Evaluation and the use of concept mapping
Evaluation and the use of concept mapping A concept is a thought, notion, or an abstract idea developed from a situation or particular instance experienced by the learner. Concept mapping consists of diagrams that represent an organized visualization of a concept and its associations or explanations (Novak Gowin, 1984). The use of concept mapping as an educational tool is well established through many branches of learning, including nursing (Schanze Grà ¼b-Niehaus, 2008; MacNeil, 2007; Trochim, 2009). Knowledge derived from the nursing process flows remarkably well into the overall design of a concept map. Although similar to other types of knowledge mapping, concept mapping provides a unique structure to gather major concepts together with direct linkages that can be easily visualized and readily examined. Properly prepared concept mapping will allow the learner to venture into all the learning domains, including cognitive, affective, and psychomotor; as well as allow the educator to move from a teacher-centered learning environment to one that is learner-centered. Concept mapping is designed to promote meaningful learning by the student, and allow for an effective formative or summative evaluation method by the educator. As the map is designed, the learner can incorporate new knowledge and reject inaccurate concepts and ideas. The map can also refine knowledge with examples or events, and allow for learning rather than route memorization. For the educator, the concept map can demonstrate the depth of the learners knowledge, and visually depict what the educator must emphasize to complete the learning process. The educator can also rapidly develop further learning opportunities through critical thinking exercises employing proposed changes to existing concept maps. Concept Mapping Theory Concept mapping was developed in 1972 as part of an effort at Cornell University to study the ability of young children to obtain basic scientific concepts. The design was the result of research into the cognitive psychology of learning and the constructivist epistemology. Based on Ausubels theory of learning, concept mapping attempts to emphasize the difference between rote learning and meaningful learning (Novak Caà ±as, 2006). Rote learning occurs when new information is added to the learners prior knowledge framework in a random and verbatim fashion. Thus, there is little permanent structure and the new information is rapidly forgotten. In meaningful learning, the new information is linked to the learners prior knowledge framework in a conscious and purposeful manner, thus producing a stable structure and substantial change in the way the learner experiences learning, in other words a conceptual change (National Institute for Science Educations College Level One Team, Universit y of Wisconsin, n.d.). This relationship is shown in Figure 1. Further studies and collaboration on concept mapping use and design, including work at the Institute for Human and Machine Cognition (IHMC) in Florida, led to integration of concept mapping with software tools and enabled rapid application of the concept mapping framework to numerous disciplines. Concept Mapping Design In concept mapping, graphical representations are arranged in two predominant manners. First, in the hierarchical fashion, the main topic or question is displayed at the top of the diagram, with inclusive and general concepts near the top and specific, less general concepts arranged in a progressively downward pattern (see Figure 2). The other most common concept map design is in a circular fashion, known as the spider method, with the core topic or idea in the center immediately surrounded by inclusive and general concepts, becoming less specific and more general the further from the core (see Figure 3). Other less common concept mapping methods include the flow path method, where concepts are linked together in a progressively linear fashion to represent a final concept, and the systems method, where input and output concepts are related to the central concept in a production-line style of visualization. Still other methods of concept mapping may be developed to reflect the learners or the educators vision of representation. Typically, concepts are enclosed in boxes, circles, or other geometric shapes with the relationships identified by connecting lines. There are descriptors on the connecting lines that specify the nature of the relationships. Concepts may also be cross-linked to show relationships between domains of knowledge or concepts located in different areas of the map (Caà ±as, 2003). Examples, events, or possible solutions can also be included, although these may not be boxed or circled, and the connecting lines can be dashed or dotted to represent an unsubstantiated relationship. Concept Mapping Construction Many methods can be used to construct a concept map. In general, the process will begin as follows: identify a question related to a process or problem; identify the key concepts of the process or problem; rank these concepts in order by identifying the most descriptive and broadest concept then narrowing the descriptions until the most specific concept is listed last; connect the concepts by links, using notations to represent the relationship between the concepts and enable meaning to the linkage; provide examples, including social, personal, and professional examples to clarify the concept or the relationship between concepts; and then continue to link, add examples, and promote the relationships. Some constructors may find it useful to perform this design using post-it notes or index cards, and arranging their ideas on a table or white board to allow for ease of concept ranking, as well the ability to provide easy changes of relationships and rapid visualization of data. The novi ce and expert alike may also use various shapes and colors to designate concepts and subconcepts to make the map clearer. Concept Mapping Software Although concept mapping may be performed with pen, paper, and other non-electronic methods, there are a number of software programs that can be used to provide a variety of concept maps with ranges of detail. In addition to using traditional word-processing programs such as Microsoft Word, Microsoft PowerPoint, or Corel WordPerfect or Corel Draw to construct concept maps, specific concept mapping software has been developed. The IHMC, a coalition of Florida universities, has developed Cmap Tools, a robust concept map developer that is free for use (IHMC, 2009). This software also includes a search feature that allows the user to search a wide variety of public Cmap databases for sample concept maps. Other software programs that are specific to concept map construction includes Axon Idea Processor, 3D Topicscape, Inspiration, MindGenious, MindMapper, MindView, Semantica, SmartDraw, Spinscape, and Tinderbox. Several of these software packages are available in multiple programming formats, in addition to several languages, and are free for download. Concept Mapping Example As an example to demonstrate concept-mapping construction, a learner is assigned to research the disease process sepsis, and make a presentation to the class. The learner studies several peer reviewed journal articles (DellaCroce, 2009; Nelson, LeMaster, Plast, Zahner, 2009; Steen, 2009) to obtain the latest information on the disease process, and decides to develop a concept map to explain the pathophysiology, risk factors, diagnostic tests, and treatments for sepsis. The learner develops a table to highlight the ideas that will be outlined on the concept map (see Table 1). Finally, using the CmapTools Knowledge Modeling Kit, Version 5.03, the learner prepares the concept map (see Figure 4). Preparation for Developing a Concept Map Steps Responses 1. Identify a question related to a process or problem What is sepsis? How is it diagnosed? What are the signs and symptoms? How is it treated? 2. Identify the key concepts of the process or problem Invading Microorganism, Sepsis, Inflammatory Response, Organ Failure, Systemic Inflammatory Response, Septic Shock, Treatments, Risk Factors, Infection, Death 3. Rank these concepts in order by identifying the most descriptive and broadest concept, then narrowing the descriptions until the most specific concept is listed last Rank 1) Invading Microorganism 2) Infection 3) Inflammatory Response 4) Systemic Inflammatory Response 5) Sepsis 6) Septic Shock, Severe Sepsis 7) Organ Failure 8) Treatment, Risk Factors, Diagnostic Tests 9) Death 4. Connect the concepts by links, using notations to represent the relationship between the concepts and enable meaning to the linkage Links are Pathophysiology, Leads To, Plus, Can Lead To, Organ Failure 5. Provide examples, including social, personal, and professional examples to clarify the concept or the relationship between concepts Vital Signs, Signs of Organ Failure, Criteria for Determining Sepsis Table 1: Preparation for Developing a Concept Map Concept Mapping Advantages Concept maps provide several advantages over other methods of instruction and evaluation. Concept maps can provide the learners access to a ââ¬Å"big pictureâ⬠view of the topic of interest, allowing the student to advance to conceptual understanding rather than simple memorization or rote learning. This in turn can provide the student the bases for critical thinking. Concept maps are also easy to construct. Concept maps can also be used as both an instructional strategy for the educator or a learning activity for the learner. As a learning activity, the student can acquire the desired knowledge, performance, and behaviors specified by the curriculum (Caputi Blach, 2008). In situations such as developing continuing education opportunities for existing nursing staff, the use of concept mapping can aid in learning new content through visualization, as many staff prefer visual or kinesthetic learning (Nursing Times, 2009). In cases where students need a platform to reduce anxiety generated prior to testing due to a lack of surety on whether the critical aspects of a clinical lesson were studied, the use of concepts maps can help students organize data, determine complex relationships between patient data and disease processes, and provide the student with an overall picture of the care provided to their patient (Hsu, 2004). Concept Mapping Disadvantages Although concept mapping has many advantages, some disadvantages exist. The wide variety of possible concept map designs can lead to additional evaluation time by the educator as students use different construction techniques. Grading of the differing concept maps may also lead to difficulties unless the educator uses strict grading criteria, such as a detailed assignment rubric. The use of concept mapping may also require a paradigm shift by learners used to only the memorization method of learning. This can sometimes cause difficulty as the learner transitions to the new method of learning. Concept Mapping Use in Learning Domains The cognitive domain includes knowledge and skill development. As cognitive learning occurs, the learner is able to recall facts, patterns, and concepts that will result in the development of intellect. Concept mapping is primarily based on the cognitive domain, as the learner combines concepts into a framework that can develop critical conceptions and critical thinking. The affective domain includes learning that is based on our interaction with our environment through feelings, values, motivations, and attitudes. Concept mapping draws into the affective domain through the construction of the framework, and the use of the environment to provide definition to the concept, and the use of values, attitudes, and feelings to link the concepts together to promote understanding. The psychomotor domain includes learning in the physical domain, such as movement, coordination, and development of motor skills. Psychomotor learning is measured through speed, precision, and techniques in execution. Concept mapping lends well to learning in the psychomotor domain, as the learner physically constructs the concept map using a variety of tools and software. Concept Mapping in Nursing Education Concept mapping is used at several levels in nursing education. By using concept mapping as a learning process in nursing undergraduate education, the educator can develop and refine critical thinking skills in the learner through generating ideas, promoting nonlinear relationships between patient data and complex disease processes, and forcing the learner to visualize the application of nursing theory to nursing practice (Abel Freeze, 2006; Phelps, Wallen, Cusack, Castro, Muehlbauer, et al., 2009). One of the most common uses of concept mapping in nursing is the use of concept mapping to demonstrate the nursing process in care planning. Each component of the nursing process (assessment, diagnosis, planning, intervention, and evaluation) can be presented around a disease process; or patient problems can be identified and relationships established between the problems to develop a holistic perspective of patient care (Taylor Wros, 2007). See Figure 5. Concept mapping can also be used effectively in formative, as well as summative assessment. In the formative assessment, the educator can provide a baseline concept map with the major concept listed and several basic relationships identified prior to lecture. The student can use the concept map during the lecture to identify further concepts and relationships, and build upon the baseline concept map to develop their knowledge base. Once the lecture is completed, the educator can use the learners maps to evaluate the effectiveness of their lecture, as well as the effectiveness of the learners attention, by examining the completed concept maps and comparing these maps to the lectures objectives (MacNeil, 2007). The baseline concept map can also be developed by the learner prior to class, such as in a homework assignment, and then completed during lecture as well. Figure 5: Sample care plan concept map (Ackley Ladwig, 2006). In a summative assessment, the educator can require a summative concept map at the end of the course to evaluate overall course objectives, as well as provide the learner with a valuable tool for future reference. Concept Mapping Function in a Learner Centered Environment Concept mapping has been used in both undergraduate and graduate nursing as an analytical tool to organize existing knowledge, synthesize new knowledge, and prioritize information in a logical, visual sequence. Concept mapping develops nonlinear cognitive function that can promote critical thinking and clinical decision making in nurses (Wilgis McConnell, 2008). This makes concept mapping an ideal strategy to switch the classroom from a teacher-centered to a learner-centered environment the learner can develop, adapt, and draw their learning directly from the concept map. Concept maps can be used by learners individually, or in small groups, to simplify complex processes and engage students in the learning process (Harrelson, 2006). As study guides, the concept maps can replace traditional question and answer study handouts with a visual map that can promote meaningful learning opposed to rote memorization (Caputi Blach, 2008). Summary Concept maps represent a collaborative learning strategy developed to take advantage of the difference between rote learning and meaningful learning. Concept maps can be used in all aspects of both undergraduate and graduate nursing, and can be used to facilitate education in all learning domains. As learners begin to analyze clinical data, the learner can begin to develop their critical thinking skills and begin to plan comprehensive care for their patients. As learners begin to study disease processes, the learners can appreciate the effects of interventions directly on patient outcomes. Educators can use concept mapping as a teaching, as well as evaluation strategy. References Abel, W., Freeze, M. (2006, September).

Qualifications of a Hero Essay
ââ¬Å"With great power there must also come great responsibility.â⬠These words from Peter Parkerââ¬â¢s uncle, along with spiders attributes, allow Peter to defeat the Green Goblin and successfully to become the hero of the story, Spiderman. Traditionally, characters who carry attributes such as strength and distinguished super-natural powers/abilities and are successful in the end are automatically known as the heroes of the stories. However, what requirements does a character literally need to be an absolute hero? In most novels today, heroes do not often hold such traditional qualities. Many have to put in effort, and pay the price to undergo this honour. In some instances, they may not even be appreciated as the heroes. Within those novels, we can identify that heroes are frequently victims of the society, victims of the immediate envies of others, which eventually lead to hostilities and cause crisis, and victims of their own isolation. These roles of heroes are apparent inside the texts of Brave New World by Aldous Huxley, and Of Mice and Men by John Steinbeck. First of all, in many cases, the heroes play roles of being victims of the society. Surviving under undesirable lifestyles causes people to suffer. They may even face harassment. When enduring in places where their different attributes are obvious to the public and yet they stand out the most, that is when people around start to harass and make fun of them. The theory of harassment as a victim of a society can be seen in Of Mice and Men: ââ¬Å"Curley stared levelly at him. ââ¬ËWell, nexââ¬â¢ time you answer when youââ¬â¢re spoke to.ââ¬â¢ He turned toward the door and walked out, and his elbows were still bent out a littleâ⬠(Steinbeck 26). As a small sized but hot-tempered boxer, Curley only likes little guys because they are who he can easily overpower. However, insecure of his size and is over-protective of his wife, Curley hates the big guys and is eager to fight anyone he perceives as a threat to his self-image. Since he is the son of the boss for whom George and Lennie work, Lennie has no choice but to stay in this terrifying situation. Noticing ââ¬Å"His (Curleyââ¬â¢s) elbows were still bent out a little,â⬠proves that Lennie unwittingly incurs Curleyââ¬â¢s antagonism as well as harassment simply because of his size. A similar case is shown in ââ¬Å"Brave New Worldâ⬠. Although John leaves the Londonà Hatchery and settles in a deserted area where only imperfect live exists, the world he is grown to live in is filled with hopelessness and yet the brave New World will stay permanent. As a result, the Savage plans to purify himself and to escape further contamination by the filth of civilized life. ââ¬Å"â⬠¦were astonished to see a young man standing outside the abandoned lighthouse stripped to the waist and hitting himself with a whip of knotted cords. His back was horizontally streaked with crimson, and from weal to weal ran thin trickles of bloodâ⬠(Huxley 226). This passage clearly demonstrates that he cleanses himself, due to the erroneous community he lives in, by carrying out a traditional Reservation religious ceremony (the whipping). Unlike Lennie, who is innocently harassed by other, John wishes to initiate self-flagellate in order for him to call on the God for forgivenes s for his lust for Lenina and lack of concern for Lindaââ¬â¢s death. In both situations, due to a heroââ¬â¢s act of being a victim of the society, he must undergo some sort of harassment. Based on these facts, one can conclude that heroes can still be victims of a society, despite that they have done nothing wrong. Other than being harassed, victims of society can also be controlled by others, which mainly results from having no options at all. In Brave New World, this concept is illustrated: â⬠ââ¬ËAnd that,ââ¬â¢ put in the Director sententiously, ââ¬Ëthat is the secret of happiness and virtueââ¬â liking what youââ¬â¢ve got to do. All conditioning aims at that: making people like their inescapable social destinyââ¬â¢ â⬠(Huxley 13). Obviously, after genetic engineering, Huxley suggests that social conditioning is the most important way for the government to enslave its people. Since the brave New World holds different classes of people, from Alphas to Epsilons, those different caste members are conditioned never to yea rn for a life other than their own. In other words, this is a major instrument for social stability which holds control of everyone within its society, including the heroes. The following scene from Of Mice and Men is another example of victims under control by others, which explains Georgeââ¬â¢s restriction on his mentally handicapped friend. â⬠ââ¬ËLennie, for Godââ¬â¢ sakes donââ¬â¢t drink so much.ââ¬â¢ Lennie continued to snort into the pool. The small man leaned over and shook him by the shoulder. ââ¬ËLennie. You gonna be sick like you was last night.ââ¬â¢Ã¢â¬ ¦ He threw a scoop of water into his face and rubbed it about with his hand, under his chin and around the back of his neck. Then he replaced his hat,à pushed himself back from the river, drew up his embraced them. Lennie, who had been watching, imitated George exactlyâ⬠(Steinbeck 3, 4). Here, it is obvious as to who is in charge between the two as Lennie carefully obeys George and imitates his actions at the riverbank. It is proven that because Lennieââ¬â¢s mind is not as bright, George simply takes this advantage and holds power over Lennie in their soci ety. Both circumstances in Brave New World and Of Mice and Men show how one can easily dominate others, leaving them no options at all. However, heroes do not necessarily suffer in a bad way when surviving under undesirable lifestyles. Indeed, they dream. They dream about their future, waiting for advancements on the current conditions. In some way, their dreams allow the heroes to dodge from reality as their depression and problems momentarily vanish. The third chapter of Steinbeckââ¬â¢s Of Mice and Men shows this concept of dreaming about conditions improving through this passage: â⬠ââ¬ËAll kinââ¬â¢s a vegetables in the garden, and if we want a little whisky we can sell a few eggs or something, or some milk. Weââ¬â¢d jusââ¬â¢ live there. Weââ¬â¢d belong there. There wouldnââ¬â¢t be no more runninââ¬â¢ round the country and gettinââ¬â¢ fed by a Jap cook. No, sir, weââ¬â¢d have our own place where we belonged and not sleep in no bunk houseââ¬â¢ â⬠(Steinbeck 57). At this point, Steinbeck clearly shows that both George and Lennie do not live in a pleasing lifestyle and both aspire to obtain a piece of land to live off. This proves that during the time the story is set, life can be very strenuous but dreams can effectively be use to repel despair. The idea of this quote links directly to the following quote, spoken by Bernard in the book Brave New World. ââ¬Å"In a different key, ââ¬ËHow can I?ââ¬â¢ he repeated meditatively. ââ¬ËNo, the real problem is: How is it that I canââ¬â¢t, or rather ââ¬â because, after all, I know quite well why I canââ¬â¢t-what would it be like if I could, if I were free ââ¬â not enslaved by my conditioningââ¬â¢ â⬠(Huxley 81). Bernardââ¬â¢s hatred for the society, which he is forced to live in, is resulted from the fact he cannot interact emotionally or physically to the community. Everyday in his life, he is treated with inhospitality and is obligated to work for something he hates the most. Therefore, sometimes during his loneliness, he will dream about himself being untangled from the brave New World he is born to live in. Unlike George and Lennie, Bernard is not able to allow his sadness fade away as he is hoping for a better future. Instead, he is even more enraged, speaking in an angered tone. From these twoà examples, it is obvious that a hero can be influenced by the society negatively, but still dreams for a better life. From all the above arguments, one can clearly realize the statement that victims of the society, whether enduring harassment of some sort, under control by others, or even dreaming about conditions improving, are often the heroes. Secondly, it is the immediate envies from others which may cause the heroes to be dragged into crisis. This takes place when a figure(s) in the story is jealous about what another has, not necessarily high-quality items such as gold or money, but whatever he does not have. Huxley displays this idea of one envying another in Chapter 12 of his book: ââ¬Å"So cordially indeed that Bernard felt a sharp pang of jealousy. In all these weeks he had never come to so close an intimacy with the Savage as Helmholtz immediately achieved. Watching them, listening to their talk, he found himself sometimes resentfully wishing that he had never brought them togetherâ⬠(Huxley 165). Basically, Helmholtz and the Savage are experiencing the same emotion of feeling not part of the society. In addition, they both enjoy poetic literature, which is what they are sharing together. In some way, their sharing of poems allows them to hide from reality as their depression and problems temporarily vanish. However, Bernard, whose knowledge is negligible in terms of literature, envies John and Helmholtz for their happiness. After attempting to jump in and break apart their conversations, Bernard is not too successful and feels like the odd man out, while also being jealous that his two friends like each other more than they like him. In Of Mice and Men, Crooks is fascinated by the strength of the friendship of Lennie and George, but also envies their relationship, by saying â⬠ââ¬ËWell, sââ¬â¢pose, jusââ¬â¢ sââ¬â¢pose he donââ¬â¢t come back. Whatââ¬â¢ll you do thenââ¬â¢ â⬠(Steinbeck 72)? Crooks asks these questions because he does not have any friends, and does not know how losing them unexpectedly will feel. Noticing that Lennie is stupid, he takes advantage of this situation to torture him mentally, which makes himself feel better and ease the pain of having others rejecting him. His face lights with pleasure at his torturing to Lennie against the friendship that Lennie has. That is to say, something that Crooks will never have. Thus, he wants other people to suffer the way that he does, of being completely alone. Apparently it is mostly the figure who envies others who must suffer,à while the target do not necessarily get harmed. Additionally, people who are envious of others set goal(s) for themselves. However, due to the fact that they cannot obtain such objective(s), they begin to look at what others have and envying occurs. In Brave New World, John hates the way that brave New World runs, hoping to twists its perspective back to the old world. He states ââ¬Å"But I donââ¬â¢t want comfort. I want God, I want poetry, I want real danger, I want freedom, I want goodness. I want s inâ⬠(Huxley 219). Here in Chapter 17 of the book, the Savage explains the old world reasoning by asserting that true life requires exposure to all things, good and evil. The unsuccessful Savage envies the Reservation Areas, where imperfect livings still exist, even though he is having a much better life in the New World. In Steinbeckââ¬â¢s novel, wanting the unattainable is also shown. From the outset of the story, Steinbeck makes the failure of George and Lennieââ¬â¢s dream inevitable. Finally, the tragedy of the ending is heightened by the fact that they never realize what just might have been possible. The first indications of this failure are revealed when Lennieââ¬â¢s mental deficiencies are demonstrated ââ¬â he is both amoral and forgetful. When he is handling the dead mouse he cannot appreciate that doing so is wrong. ââ¬Å"I wasnââ¬â¢t doing nothing bad with itâ⬠(Steinbeck 9). Lennie cannot distinguish between right and wrong, which seriously challenges the success of th eir dream. We are given more doubts when we learn of Lennieââ¬â¢s actions in Weed. ââ¬Å"You ainââ¬â¢t gonna do no bad things like you done in Weedâ⬠(Steinbeck 7). When George says this he is almost tempting fate, and when Curleyââ¬â¢s wife is introduced, their dream heads off the track. Considering what Lennie did in Weed, Curleyââ¬â¢s wife was a major threat; she was a problem just waiting to be occurred. Throughout the book, Steinbeck develops the idea of the dreamââ¬â¢s inevitable destruction. Steinbeck has clearly emphasised the fact that the dream was never going to happen. In both instances, the heroes are hoping to reach one goal which indeed is not reachable. Frequently, it is because of these unattainable objectives that give the heroes disappointments. In Huxleyââ¬â¢s Brave New World, however, it is the heroââ¬â¢s dissatisfaction of his society that leads him to setting an unreachable goal. John states ââ¬Å"Linda had been a slave, Linda had died; others should live in freedom, and the world be made beautiful. A reparation, a duty. And suddenly it was luminously clear to the Savage what he must do; it was as though a shutterà had been opened, a curtain drawn backâ⬠(Huxley 192). Here, John realizes that something has to be fulfilled to modify this erroneous society, or the brave New World. As of the day when John and his mother come to the London Hatchery Centre, Linda is feeling unwell. Although she is given somas to keep her in ââ¬Å"holidayâ⬠, John believes that somas are poisonous while also enslave the public. It is at this point that the Savage notices his reason for coming to this strange world: he will make it free. Conversely, George in Of Mice and Men is disappointed with his companion Lennie, who in fact, is one of the toughest barriers of reaching their dream of owning a farm. From the quote â⬠ââ¬ËGod, youââ¬â¢re a lot of trouble,ââ¬â¢ said George. ââ¬ËI could get along so easy and so nice if I didnââ¬â¢t have you on my tail. I could live so easy and maybe have a girlââ¬â¢ ââ¬Å"(Steinbeck 7), we become aware that George is reluctant to carry Lennie around. However, he has to bear with this responsibility due to the death of Lennieââ¬â¢s Aunt Clara. Although they both want a better life and put in the effort to attain this goal, they never seem to be very successful. Ultimately, it is Lennie whom George blames for their failure. Whether it is the heroââ¬â¢s disappointment that leads to setting an unattainable goal or it is the unreachable goal which leads to his disappointment, these two examples show that one will still suffer with distress of dissatisfaction to some degree. Certainly jealousy of others, wanting the unattainable and undergoing disappointment are the results of immediate envies from others. Frequently the heroes, victims of isolation are such roles. They feel differently about themselves compared to the public and therefore, the act of setting themselves apart from others takes place. To begin with, the decrease of self-confidence of the heroes, due to a number of reasons, is one of the main causes that eventually lead to self-banishment, or oneââ¬â¢s isolation. The friendship between John, Helmholtz and Bernard in Chapter 12 of Brave New World shows this concept of self-confidence diminishing: ââ¬Å"He was revenging himself on his two friends for liking one another more than they liked him. In the course of their next two or three meetings he frequently repeated this little act of vengeance. It was simple and, since both Helmholtz and the Savage were dreadfully pained by the shattering and defilement of a favourite poetic crystal, extremely effective. In the end,à Helmholtz threatened to kick him out of the room if he dared to interrupt againâ⬠(Huxley 166). Although John and Helmholtz experience depression, both enjoy sharing their unique poetic ideas together. By doing so, their sadness towards the society gradually evaporates. Bernard, however, is the odd man out and is very regretful of bringing them two together. Perhaps he is jealous of the friendship he creates. It is what John and Helmholtz have in common, which Bernard does not, that tightly bonds their relationship while Bernard is left out. As his two companions like each other more than they like him, his self-confidence decreases and envying starts to occur. In addition, Bernard believes that he cannot correspond to John because John is more desirable and knows more than he does. Ultimately, this odious sentiment keeps returning to Bernard as Helmholtz and John continue to share their thoughts and even threaten to boot Bernard out if he interrupts again. As a result, the friendless Bernard cannot relate to his only friends and loses his self-confidence significantly. The concept of oneââ¬â¢s isolation that results from low self-confidence of a hero decreasing also appears in Of Mice and Men. From the quotes ââ¬Å"He kept his distance and demanded that other people keep theirs. His body was bent over to the left by his crooked spine, and his eyes lay deep in his head, and because of their depth seemed to glitter with intensity. His lean face was lined with deep black wrinkles, and he had thin, pain-tightened lips which were lighter than his faceâ⬠(Steinbeck 67) and â⬠ââ¬Ëwhy ainââ¬â¢t you wanted?ââ¬â¢ Lennie asked. â⬠Cause Iââ¬â¢m black. They play cards in there, but I canââ¬â¢t play because Iââ¬â¢m black. They say I stink. Well, I tell you, you all of you stink to meââ¬â¢ â⬠(Steinbeck 68), we can identify the fact that Crooksââ¬â¢s self-confidence reduces only because of his physical appearance and attributes. Since this book takes place during the 1930ââ¬â¢s and discrimination, sadly, still exists, this Negro experiences isolation because of racism. It is this that the other farmhands believe that it is necessary not to allow, as it seems a privilege in their minds, Crooks to live with them. Furthermore, his separation from others causes his severe loneliness spending his nights reading and his days alone in the barn working on the horses. He is treated as an outcast and underling and is forced to find friendship in the only thing assessable, the books he reads. Crooksââ¬â¢s distance from others eventually causes his downfall, and his downfall also stretches their bonding. From the two circumstances, we canà conclude that oneââ¬â¢s judgements are usually base on his physical looks, instead of oneââ¬â¢s true behaviours and characteristics. This is a reason why many characters in a story, including heroes, frequently lose their self-confidence which eventually leads to self-banishment of themselves. Moreover, it is because of these reductions in terms of heroesââ¬â¢ self-confidence that causes their withdrawal from a society. Without confidence, they are afraid to be harassed and teased, and are too weak to face the public, resulting isolation in personal. This idea of withdrawing from a society is demonstrated here by Huxley in Chapter 11, stating â⬠ââ¬ËBut I do,ââ¬â¢ he insisted. ââ¬ËIt makes me feel as though â⬠¦Ã¢â¬â¢ he hesitated, searching for words with which to express himself, ââ¬Ëas though I were more me, if you see what I mean. More on my own, not so completely a part of something else. Not just a cell in the social bodyââ¬â¢ â⬠(Huxley 81). The Top Ten Controllers in Brave New World initiate Bernardââ¬â¢s hatred on his society, due to the ways on how the society runs. This links to Bernardââ¬â¢s downfall. The policies of the brave New World, such as to insert alcoholic materials into Gammasââ¬â¢ blood surrogate, indirectly cause Bernardââ¬â¢s downfall. In addition, sleep-teaching hypnosis makes people (in the society) to automatically associate heights with caste levels, thus making it more difficult for others to respect Bernard, who indeed, is an Alpha. Base on this quote, Berna rd wishes to look at the ocean, peacefully, and enjoy it. We can identify that Bernard always wishes to be by himself and extract from the society, instead of being part of the social group. However, his ability may not allow this dream to come true. The concept of withdrawing from the society also takes place in the novel Of Mice and Men, shown in this quote: â⬠ââ¬ËSââ¬â¢pose you didnââ¬â¢t have nobody. Sââ¬â¢pose you couldnââ¬â¢t go into the bunk house and play rummy ââ¬â¢cause you was black. Howââ¬â¢d you like thatââ¬â¢ â⬠(Steinbeck 72). From this, one can identify why Crooks is withdrawing from his society. This black handicap has a strong difference from the rest of the crew, as he must live in a separate room from the rest of the workers. No one in the novel ever feels any sort of empathy or even tries to comprehend what Crooks is saying. This is Steinbeckââ¬â¢s mechanism for displaying Crooksââ¬â¢s isolation from the public. For Crooks, he has never been treated well by any of his co-workers because he is black. In addition, Crooks also does not know how to relate and function normally anymore because of how his loneliness hasà effected him. Loneliness has made Crooks a very bitter individual, while he is truly not able to leave this situation because of his race during the entire novel. Proven in both instances, characters are frequently born with imperfections, depending on their society, leading to their extraction from the public and causes isolation. For this reason, victims of oneââ¬â¢s isolation experience loneliness as well. In a way, everyone needs someone to talk to, whether it is a family member, a friend, or even a pet, as a source of comfort and wealth for the person. Yet most heroes never seem to behave in such a way. This belief of one feeling lonely can be displayed within this passage: ââ¬Å"From Guildford the down-line followed the Wey valley to Godalming, then, over Milford and Witley, proceeded to Haslemere and on through Petersfield towards Portsmouth. Roughly parallel to it, the upline passed over Worplesden, Tongham, Puttenham, Elstead and Grayshott. Between the Hogââ¬â¢s Back and Hindhead there were points where the two lines were not more than six or seven kilometres apart. The distance was too small for careless flyers-particularly at night and when they had taken half a gramme too much. There had been accidents. Serious ones. It had been decided to deflect the upline a few kilometres to the west. Between Grayshott and Tongham four abandoned air-lighthouses marked the course of the old Portsmouth-to-London road. The skies above them were silent and deserted. It was over Selborne, Bordon and Farnham that the helicopters now ceaselessly hummed and roared. The Savage had chosen as his hermitage the old light-house which stood on the crest of the hill between Puttenham and Elsteadâ⬠(Huxley 222). Here, Huxley thoroughly explains the fact that John wishes to escape from the London Hatchery Centre as far as possible. He has decided to isolate himself from the society and to live away with pain and loneliness, due to his opposition in terms of the brave New Worldââ¬â¢s principles. George in Of Mice and Men also demonstrates the concept for a hero being lonely: â⬠ââ¬ËI ainââ¬â¢t got no people. I seen the guys that go around on the ranches alone. That ainââ¬â¢t no good. They donââ¬â¢t have no fun. After a long time they get mean. They get wantinââ¬â¢ to fight all the timeâ⬠¦ ââ¬ËCourse Lennieââ¬â¢s a God damn nuisance most of the time, but you get used to goinââ¬â¢ around with a guy anââ¬â¢ you canââ¬â¢t get rid of himââ¬â¢ â⬠(Steinbeck 41). Clearly, George proclaims his view on loneliness to give a reason for his connection with Lennie. This connection George has with Lennie makes the two of them unique to the rest of theà characters. Many of the men on the ranch have a dream, but only Lennie and George have a chance of obtaining it. Essentially, John Steinbeck wants to show that although George and Lennie have the advantage of being a team, they will never accomplish it because all human beings are in essence, alone. Thus, Georgeââ¬â¢s constant playing of the game of solitaire, ââ¬Å"cutting the cards again and put out a solitaire layâ⬠(Steinbeck 28) foreshadows his eventual decision to become a solitary man. Within these two occurrences, one can realize that heroes are affected by the society, which brings them loneliness and isolation. Based on the above examples, it is proven that heroes self-banish because of their weak self-confidence, which ultimately leads to withdrawal from society and subsequent loneliness. We learn from Brave New World and Of Mice and Men that being an absolute hero requires not only traditional skills and abilities, but also being able to withstand great hardships. In both novels, the heroes had to endure being victims of their societies, victims of envy from others, and victims of their own isolations. Despite them undergoing many difficulties in the stories, Bernard and Crooks are not the heroes because neither of them follows the hero monomyth structure. Yet to some extent, they were neither able to escape nor did they survive. Although based on the script, John, for example, left the London Hatchery and decided to live in a deserted area where only imperfect live exists. However, deep down in Johnââ¬â¢s mind, he knew that the world would never experience the same freedom he is grown to love. In spite of everything, he is trapped by the hands of the controllers of the brave New World. Similar to John, Lennie is forever locked in his mentally handicapped mind and be tricked and betrayed by his best companion, George. As heroes tend not to have successful conclusions, why will anyone choose to be honoured with such positions? If you are required to carry out non-traditional-qualities and/or hardships throughout a story, are you willing to be a hero when given an opportunity?

Integration Across A Range Of Learning Areas Education Essay
The universe around us is non compartmentalised or fragmented, nor are experiences and activities wholly independent of each other. This mixture and blend of experiences are all inter-related and do up the tapestry of life. On a similar note, the taught course of study should reflect this integrating to more efficaciously prosecute immature scholars in an educational procedure which consists of mostly complimentary countries of acquisition. Integrated acquisition is far from a new construct but until late mathematics has struggled to incorporate successfully with other topics. Whilst there is no remarkable educational theoretical account that can be adhered to, the premiss remains ; that of taking several topics and incorporating them with one another with the purpose of larning going enhanced exponentially across all involved capable countries. Mathematicss has such a wide range of application it is wholly appropriate that it should be integrated prolifically across a scope of capable countries. Integration works more efficaciously when there is a clear point of focal point for curricular countries to aim. This synergism of capable countries with a specific end can so complement each other in a much more valuable mode. Advantages of integrating include: Can profit students in apprehension and appreciating links between capable subjects, and a better apprehension of how this relates to life. It can relieve planning force per unit area on instructors. Curricular thoughts are connected. Boundaries sometimes related to learning a specific subject can be eschewed. It can supply a valuable tool for support. More significance and relevancy can be taken from the larning experience. Some disadvantages include: Additional planning of plans is required in order for different topics to be coordinated and to run at the same time. This besides means that a close respect to context and clip is indispensable if the integrating plan is to be effectual. If this is non considered so the consequence can really go damaging. The pureness of some capable countries ( including the existent range of the subject ) can go baffled or lost if attending is non paid. More expertness is required on behalf of the instructors in order to maximize acquisition by effectual integrating. ( Maude, 2001 )The usage of oppugning in a constructivist environment.ââ¬ËIn order to protect students ââ¬Ë self-pride and develop assurance, it is of import that oppugning takes topographic point in an encouraging and supportive ambiance ââ¬Ë ( Kyriacou, 1986 ) . Constructivism is a theory about how people learn based on scientific survey and observation. It states that through a procedure of experience and contemplation we develop ( or concept ) our ain apprehension of the universe. New experiences are reconciled with old thoughts and apprehension, sometimes changing old beliefs and sometimes going disregarded as irrelevant compared to these old beliefs. Questioning is of import when following a constructivist attack to instruction. Through pertinent oppugning pedagogues can help pupils in the building of their cognition instead than reproducing lists of facts for memorization. Questioning students is an of import tool in helping enquiry based acquisition activities and job resolution. Constructivist instruction should animate the pupils ââ¬Ë natural wonder and desire to larn how things work. Learners should be engaged by using their existing theories and experience and finally organizing valid decisions based on their findings. ( Brooks & A ; Brooks, 1993 )The usage of drama in a rich environment.The physical environment holds great power for learning possible. The environment can impact mathematical acquisition and instructors should take great attention to see how their schoolroom infinite can be arranged in order to advance kids ââ¬Ës mathematical acquisition experience. ( Carol & A ; Galper, 2001 ) The mathematically rich larning environment can be farther enhanced with drama, supplying puils the chance to see and prosecute with mathematics whilst seeing grownups apply these techniques in real-world scenarios. Supplying a mathematically rich larning infinite can better the students mathematical accomplishments by rote. ââ¬ËIn adult-guided schoolrooms, instructors provide scaffolding by introducingaÃâ à ¦ stuffs in the drama Centres and discoursing with kids how to utilize materialsaÃâ à ¦ The pupils in those schoolrooms, in bend used more printed stuffs with attending to their printed facets and produced more printed stuffs than pupils in schoolrooms with no specific instructor counsel ââ¬Ë ( Gunn, Simmons & A ; Kameenui, 1995 ) .The ongoing nature of appraisal and planning for learning.The procedure of designation, reading and turn toing the acquisition of pupils is the kernel of appraisal. The intent of appraisal is chiefly to supply information on the advancement and ongoing accomplishment of scholars in order to set up a way for future educational scheduling. It is important to describe this appraisal in order to inform and back up farther instruction via the proviso of of import feedback to the students themselves, their other instructors and their parents. Appraisal in the schoolroom is a cardinal component of developing larning schemes. In a competitory universe which is rapidly altering it is of import to develop citizens who are competent and capable of independent and flexible idea. It is besides of import that these citizens can believe for themselves. Certain appraisal schemes are more suitable to peculiar course of study results than others and it is of import for instructors to develop relevant schemes which are appropriate to the topic or method which they are using. ( Black & A ; Wiliam, A 1998 )Mathematical content cognition.It is of import for instructors to develop a sound apprehension of their topic. When learning mathematics it is important for instructors to non merely develop an apprehension of of import mathematic constructs but they should besides be able to explicitly appreciate the connexions on a cardinal degree between what they are learning and what they are larning. Teachers of maths should hold a deep apprehension of processs, constructs and concluding accomplishments that are appropriate and cardinal to the nature of the elements they are learning. It is indispensable that maths instructors know how to link and stand for mathematical thoughts whilst efficaciously pass oning them in an appropriate mode. Students should hold assurance in the pedagogue ââ¬Ës apprehension of the topic and conversely larn to appreciate the diverseness, power and public-service corporation of the topic. The instructor should be able to convey these thoughts efficaciously and understand pupil believing in footings of inquiring, scheme, misconceptions, etc. whilst turn toing these issues in such a mode that it supports and promotes pupil acquisition. ( Kilpatrick, et al. , 2001 )The usage of relevant course of study paperss.The usage of hands-on resources and manipulative ââ¬Ës.Developmental spheres, temperaments and larning manners.ââ¬ËIt is really of import to gain that within any mathematics set at that place will still be marked differences in the mathematical attainment of students. It is indispensable that the instruction takes history of these differences and is antiphonal to the demands of single students. It should non be assumed that the same instruction attack will be needfully suited to all in the group ââ¬Ë ( Cockcroft, 1982 ) _REFERENCE

Do Radioactive Elements Glow in the Dark
In books and movies, you can tell when an element is radioactive because it glows. Movie radiation usually is an eerie green phosphorescent glow or sometimes a bright blue or deep red. Do radioactive elements really glow like that? The Science Behind the Glow The answer is both yes and no. First, lets take a look a the no part of the answer. Radioactive decay may produce photons, which are light, but the photons are not in the visible portion of the spectrum. So no... radioactive elements do not glow in any color you can see. On the other hand, there are radioactive elements that impart energy to nearby phosphorescent or fluorescent materials and thus appear to glow. If you saw plutonium, for example, it might appear to glow red. Why? The surface of plutonium burns in the presence of oxygen in the air, like an ember of a fire. Radium and the hydrogen isotope tritium emit particles that excite the electrons of fluorescent or phosphorescent materials. The stereotypical greenish glow comes from a phosphor, usually doped zinc sulfide. However, other substances may be used to produce other colors of light. Another example of an element that glows is radon. Radon ordinarily exists as a gas, but as it is cooled it becomes phosphorescent yellow, deepening to glowing red as it is chilled below its freezing point. Actinium also glows. Actinium is a radioactive metal that emits a pale blue light in a darkened room. Nuclear reactions may produce a glow. A classic example is a blue glow associated with a nuclear reactor. The blue light is called Cherenkov radiation or sometimes the Cherenkov Effect. The charged particles emitted by the reactor pass through the dielectric medium faster than the phase velocity of light through the medium. The molecules become polarized and quickly return to their ground state, emitting visible blue light. Not all radioactive elements or materials glow in the dark, but there are several examples of materials which will glow if the conditions are right.
