Lord of the Flies as a Religious Allegory Essay

There are numerous approaches to peruse  «Lord of the Fliesâ ». To some it is essentially an experience anecdote about a gathering of young men abandoned on a remote location, others decipher it, and consider the to be as allegories for significant parts of our regular day to day existences. A few unique speculations have been introduced, professing to clarify Golding’s imagery. What many appear to have neglected, is that the appropriate response is in that spot before them. It is in the title:  «Lord of the fliesâ », an interpretation of the greek word  «Beelzebub ». Also, what do the vast majority consider when they hear this name? The Devil, Satan himself†¦  «Lord of the Fliesâ » is a purposeful anecdote indicating the battle among Christian and Pagan qualities. The character that more than anybody speaks to Christianity in the book is Simon. The first occasion when you read through the story, he is presumably the character that is the hardest to depict an d discover a reason for. He is unique and doesn't fit in among different young men, But in the event that you go further into the book, it turns out to be increasingly more evident that Simon’s life on the island is strikingly like the life of someone else that didn't fit in. An individual that experienced somewhere in the range of 2000 years back in Israel. Much the same as Jesus Christ Simon thought about the little and helpless, he adored nature and all living. Simon is likewise a prophet. He realizes that Ralph will return to progress alive. He doesn't utter a word about himself or Piggy. Neither Simon nor Jesus are ever frightened, in light of the fact that they are sure that what is intended to happen will win. They were both ready to challenge the obscure and overcome it. Jesus prevailed upon death, Simon confronted the Beast and returned alive. Jesus did it for all the individuals living on Earth, Simon for different young men. What is so perplexing and miserable is that they were both murdered when they attempted to share what they had discovered. They were both murdered out of frustration and in the conviction that they were malevolent. On the opposite side, speaking to agnosticism and indulgence, we see Jack and his trackers. All they care about are themselves. They would prefer not to live by any standards and they don't have any regard for the island, They consume and murder without stresses, all to satisfy themselves. The clan lo ses all highlights of human progress, the main thing that impacts them, aside from their own will, is the dread of the Beast. None of them haveâ ever seen a real beast, however it is a dread of the obscure. From multiple points of view the Beast turns into a religion for the young men. As we probably am aware trackers did in old occasions, the choirbboys begin to forfeit piece of their prey, They leave meat with the goal that the Beast will like them and disregard them. The most theoretical and emblematic episode in the book happens when Simon sees this penance. The image of Christianity, and what is acceptable, meets the image of the Devil, and all that is underhanded. We realize that Simon is just fantasizing a result of his epilepsy, yet a great deal of what he sees bode well. The sow’s ridiculous head persuades him that  «Ã¢â‚¬Ëœeverything is awful business’†¦ The half closed eyes were diminish with the interminable cynisism of grown-up life.â » The Lord of the Flies says  «Fancy thinking the mammoth was something you could chase and kill†¦ I’m part of you†¦ I’m the motivation behind why it’s no go†¦ Why things are they are.â » What Golding is stating that the Devil is shrouded some place somewhere within all individuals. Without ethics, lawfulness it will in the long run surface and come out. http://www.malvik.vgs.no/engelsk/allegory.htm (1 of 2)4/20/2005 5:55:48 PM allegory http://www.malvik.vgs.no/engelsk/allegory.htm (2 of 2)4/20/2005 5:55:48 PM

But there are times that remarriage does occur. In fact, according to one study, as many as 10% to 15% of all divorced couples will reconcile.?? In those cases, the couples may have realized that the grass really wasnt greener on the divorced side. Or, maybe time did heal all wounds. Whatever the reason, remarriage between divorced couples does happen on occasion. If youre thinking of rekindling the romance with an ex-spouse, there are some critical things to consider first. Why Divorced Couples Get Remarried While the reasons for getting remarried vary from couple to couple, many people realize after the anger and frustration dissipate that they actually miss their former spouse, especially if they were married for any length of time. Then, they start to wonder what they could have done differently or if the marriage could have been salvaged. Some people even wonder if they made a mistake. Here are some other possible reasons divorced couples consider remarrying one another.?? Realize single life is unsatisfying and difficultRecognize they divorced impulsively or for stupid reasonsRealize theyre still in love with their exExperience some personal growth that led them back to the relationshipMiss the familiarity they had with their ex  Forgive and/or forget the things their ex did wrongMaintain a positive relationship with their exs family Things to Consider Before Remarrying Before you remarry your ex, you need to be sure you are both ready for the work involved because it wont be easy. And, statistically speaking, the odds are against you. For instance, second marriages often end in divorce more often than first marriages. In fact, according to Psychology Today ... a whopping 60% of remarriages fail. And they do so even more quickly; after an average of 10 years, 37% of remarriages have dissolved versus 30% of first marriages.?? If you and your ex-spouse are committed to the idea of getting back together, you need to remember these three things: The odds are against you.You must take things slowly.You should see a marriage counselor and take a marriage education course.?? Making Your Second Time Around Together Successful If you are committed to remarrying your former spouse, you should plan on being in a loving relationship for a minimum of a year before tying the knot again. During that time, you need to address the reasons why you divorced in the first place. After all, you are marrying the same person. While you both may have experienced some personal growth since the divorce, there still will be things about your ex that annoy you. Here are some suggestions to improve your chances of having a successful second marriage to one another. Get Counseling Marriage counselors agree that you must learn from your marital history or the two of you are doomed to repeat the same mistakes. Unresolved and unfinished business will resurface.?? Honestly look at what caused your divorce. If the marriage failed because of finances, be clear on how you will spend money. If problems revolved around parenting issues, work this conflict out first. If the divorce was due to infidelity, process the unfaithfulness, forgive, and rebuild trust. You also may want to read a marriage book together and take a marriage workshop  or course. The more work you do on the front end of your relationship, the better off you will be after you remarry. Building a new foundation takes time and effort. You have to confront past issues that caused conflict and learn new ways of interacting. Take a Personal Inventory When divorce happens, no one is blameless. Even if infidelity was the primary reason for the divorce, there are bound to be other issues in the marriage. And while those issues do not excuse the unfaithfulness nor can they be blamed for it, they still need to be addressed. Admit to your role and responsibility in what went wrong in your first marriage. If you cant readily do this, you will continue to struggle in this marriage. You also need to keep things completely honest between the two of you. There should be no game playing, no mind reading, and no unspoken expectations. Share with one another your hopes, dreams, and expectations. Consider Your Children Getting back together just for the sake of the kids is a bad idea. Get back together because you love (and like) one another and want to be together again.  If you do have children, dont let them know youre dating again for a while. They could get their hopes up that you will reconcile. These hopes also could put pressure on you to remarry even if things are not going as well as you would like. Be Realistic It is important to recognize that the first marriage is dead. As hard as this may be, do not let that ghost hurt your new marriage. Dont dwell on the mistakes you made in the previous marriage. Instead, focus on your future together. Also, make sure you have reasonable expectations. At the core, you will be marrying the same person. Some of the old, annoying habits will still be there. And, if you discover that things arent right, trust your gut and end the relationship.   A Word From Verywell Whatever you do, dont rush into a second marriage with your ex-spouse. Developing trust and making a marriage work requires a strong commitment by both of you. Take time to understand the dynamics of your relationship more fully before getting married again.

Smoking and the Effects on the Heart Essay - 1413 Words

The Surgeon General has called it the leading preventable cause of disease and deaths in the United States. Smoking is among the top preventable risk factors of heart disease amongst many other health problems. Coronary heart disease and strokes are the primary types of cardiovascular disease caused by smoking. They rank as the first and third leading causes of death in the United States. More than 61 million Americans suffer from some form of cardiovascular disease. Smoking increases your risk for high blood pressure, coronary heart disease, stroke, congestive heart failure, and aneurysms to name a few. More than 2,600 Americans die every day from cardiovascular diseases. To function effectively, the heart needs a constant supply†¦show more content†¦Smoking creates toxins in the blood. This greatly contributes to the development of atherosclerosis. Atherosclerosis is a condition in which fatty material is deposited along the walls of the arteries. This fatty material thickens, hardens, and can eventually block the arteries if not treated. Clots may also form around the plaque deposits. Smoking raises the levels of proteins that cause the blood to clot and also increases platelet production, making the blood stickier which further creates risk for clots. This also interferes with the blood flow and poses an added danger if they were to break off and travel through the body causeing assorted health problems such as heart attack, stroke, or gangrene. As soon as you begin to smoke, you cause immediate health risks. Within one minute of smoking, the heart rate rises significantly, as much as 30% in the first 10 minutes. Nicotine also raises blood pressure. Blood vessels constrict, forcing the heart to work harder. This makes it more difficult for the oxygenated blood to be pumped efficiently to the rest of the body. Carbon monoxide in tobacco smoke also diminishes the bloods ability to carry oxygen in the blood. It attaches itself to hemoglobin much more easily than oxygen does. Hemoglobin is what carries oxygen in the blood. Also, Smoking decreases HDL, or good cholesterol. It also increases LDL, bad cholesterol.

Taking a Look at Sports Psychology - 1561 Words

Don’t think of a pink elephant. Come on – don’t let the picture creep into your mind. Stop thinking of that†¦ Pink Elephant (Gardner). It has been proven that putting a â€Å"don’t† or a â€Å"not† into a statement can cause the brain to have difficulties in interpreting the statement. In sports, players tend to tell themselves â€Å"not† to do something. In soccer, a goalie might tell him/herself to not let the other team score a goal, and then the team does. Or in tennis, players tell themselves not to serve the ball into the net, and then they do just that. Sometimes they tell themselves to â€Å"do† something, and that athlete might end up doing the unthinkable. With three seconds left in the game, a basketball player might take the three-point shot and win the game, even though they have never been able to make that shot before. These types of scenario tend to happen all the time. Psychology, or the mental game in spo rts, is so important it can completely change the outcome of the game. Sports Psychology has become more and more influential in understanding how to play the game. Serious athletes are now training their mind just as much as they train their body. They have found that to be a champion, it now takes more than just being fit and having talent.

(2012, ch 2) the son Thomas has had to build new relationships and adapt to changes that he is not familiar and comfortable with. With the involvement of professionals Thomas was introduced to a speech and language therapist Task 1 Question 3 The focus of this essay is to describe the three parenting styles and to discuss how they might impact on children’s behaviour. The three parenting styles are authoritarian parent, an authoritative parent and a permissive parent. I am also going to describe other factors that may impact on children’s behaviour, such as changes in a child’s life, the involvement of professionals in children’s lives, the early learning stages and also the transition children experience when having to detach from their primary carer to attend day-care or school. Authoritarian parents are considered as being disciplined, strict and controlling. Rules are set and they expect their child to follow them. They will not allow the child to make any choices or decisions of their own. They use a tough disciplined technique. The rules imposed are not open to negotiation with the child. They often will not explain the reasons why the rules are being imposed and also enforce their own punishment when a rule is broken. Similar, but different to, is the authoritative parent. They are also defined as strict but they have more of an understanding approach to their child when boundaries have been broken. The parent will set boundaries, rules and guidelines that are plausible rather than enforce unrealistic ones. They will explain to the child the reasons why they are being introduced, should they broken, they will also issue non-punitive punishments. The third style is a permissive parent. They recognise their child’s developmental and emotional needs but they have difficulty imposing rules and setting boundaries. This style teaches the child that rules do not have to be followed. They are also described as being soft and too easy going. Permissive parents become a friend rather than a parent and tend to ‘give in’ to their child very easily. A child’s behaviour can be both good and bad, so parenting styles can have a positive and a negative effect on a child. Majority of children’s behaviour problems take place during times of change and transition, this is a natural progression of development. Child psychiatrist and educator Rudolph Dreikurs (1897-1972), believed â€Å"that all humans, as social beings, want to belong and be accepted by others. He identified four goals for misbehaviour: attention, power, revenge and display of inadequacy† Colloby et al. (2012, p. 62). With the focal family in Colloby et al. 2012, ch 2) the assistance of Dreikurs four goals for misbehaviour gave Cara a better understanding of both her children. Cara was able to reflect on this information, and was able to take an impartial and objective look at her children’s behaviour and address it. Initially the parenting style both Cara and Alastair were trying to establish with Thomas and Rowanna, had a disciplined approa ch, however, as they lived with Alastair’s mum Diane, she had a soft approach, and this did not help the situation as Diane would give in to their every needs, she adopted more of a permissive style. Children in this situation can get confused and frustrated not knowing which is right and which is wrong. Children require consistency as this can greatly impact on how they grow and develop. As well as the overall parenting style, family’s lives are affected by outside factors, such as changes in a child’s life can also affect behaviour. With the focal family in Colloby et al. (2012, ch 2) the son Thomas’s behaviour since being diagnosed with having a hearing impairment has had a significant effect on the family. Thomas has had to build new relationships and adapt to changes that he is not familiar and comfortable with. With the involvement of professionals Thomas was introduced to a speech and language therapist. In addition to the sessions they carry out together, Cara and Alastair play an important role carrying out further exercise and activity sessions at home. The home sessions became mundane and tedious, and Thomas was getting upset because he no longer wanted to do them. Early learning stages of a child’s life can create an impact on children’s behaviour as Swiss biologist and psychologist Jean Piaget (1896-1980) â€Å"is renowned for his four-stage model of child development that linked children’s behaviour to different stages of development† Colloby et al. (2012, p. 42). Russian psychologist, Vygotsky (1896-1934) â€Å"believed that learning occurs when a child is supported by another person to do what they could not do alone. He called this the ‘zone of proximal development’†. Colloby et al. (2012, p. 43). Whilst I agree with Piaget’s first two stages of cognitive development, the sensori-motor stage, whereby infant’s 0-2years will practice play and be allowed to explore and experience things for themselves, and the pre-operational stage, 2-7years, when a child’s play will replicate their own experiences, and they will see things from their own perspective using their own imagination, I also agree with Vygotsky’s beliefs that children can copy a person and learn from them. Some children can be further developed than others and so a child more conversant in play can assist with another child’s development. Transition in children’s lives can impact on their behaviour when a transition to daycare or school occurs. In Society today it is much more common for both parents to go out to work, Colloby et al. (2012, p47) and so the need for childcare facilities increases. Childcare professionals play an important role in the lives of the twenty-first century family for a number of reasons, Colloby et al. (2012, p. 47). An example of this could be a child possibly needing to attend day-care before they attend school so parent(s) are able to continue with their careers. By accessing the day-care placement, a child would be allocated a key person. The role of the key person is for the child to develop a bond with them so that they will make them feel safe and secure. The choice of parenting style is crucial to a child’s psychological and social development. Baumrind suggested that the majority of parents display one of three different parenting styles, Colloby et al. (2012, p. 70). The chosen style should provide a loving, supporting and disciplined approach to build a healthy and happy child. A parent’s behaviour towards a child can potentially impact significantly on his or her wellbeing. The style is generally based on how they were reared themselves, or, it can be as a result of this that they choose another. It can also be chosen as a result of the society in which they live, their ethnicity or their cultural groups.

John Deere Steel Plow Essay Example

John Deere Steel Plow Paper We chose our topic, the Cast-Steel Plow by John Deere because we all live or have lived on a farm in some period of time and found it would be interesting topic to learn more about the cast-steel plow. We thought that since we have used some type of plow we wanted to know more about it and how it was invented. We found most of our research in books like John Deere’s Company: A History of John Deere And Company and its times, also John Deere Tractors and Equipment. We have contacted John Deere’s Company in Illinois, Living History Farms in Urbandale, and Pomery Living History Farms in Washington. Also more information from Deere. com, and also facts from our American History books. How we chose our presentation category was how all three of us were more familiar with creating good boards and thought that if we could all think about our topic together so we could get a lot more information about our topic, and wanted to come up with a good idea for our board. Our project relates to the NHD theme because the steel plow was a meaningful product to farmers of the 1800s. The John Deere Steel Plow changed history forever since the land was much too rich. The Cast-Iron Plow could only go for a couple of feet and then the farmers would have to scrape off the sod. The steel plow made it easier for the farmers of the 1800s to push and also farmers could plow more acreage then a cast-iron plow. The John Deere cast-steel plow impacted the farmers back in the 1800s and it affects us now in farming. It makes everything easier, now then it has ever before.

The Need for Wireless Standards and Protocols essayEssay Writing Service

The Need for Wireless Standards and Protocols essayEssay Writing Service The Need for Wireless Standards and Protocols essay The Need for Wireless Standards and Protocols essayToday, the development of technologies contributes to the wider emergence of wireless networks that open new opportunities for communication and data sharing. However, the rise of the popularity of wireless networks raises the problem of the introduction of reliable and safe wireless standards and protocols. At the moment, wireless standards and protocols remain, to a certain extent, under-regulated and under-developed. As a result, the risk of information breaches persists along with the risk of misusing wireless networks for the access to the private information and other cyber crimes. In such a situation, wireless standards and protocols need consistent enhancements not only at the domestic level but also internationally and such organizations as the Federal Communications Commission or the International Organization of Standardization should regulate the development of wireless networks and technology through setting effective wi reless standards and protocols.The Federal Communications Commission is the US federal government body that regulates the communication market, including the wireless market in particular. In fact, the Federal Communications Commission does not limit its functions by the control over businesses but also it expands its control on private means of communications introducing standards and regulations that determine the development of the communications industry in the US. In this regard, the Federal Communications Commission has the authority to regulate wireless technology and networks in the US. The regulation occurs through the establishments of norms and standards which all users in the US have to respect. Otherwise, the Commission will use its authority to impose sanctions and launch the legal prosecution on businesses and individuals that violate established norms and standards.The ISO is the international organization that establishes standards in different fields, including the wireless technology and networks. At this point, it is worth mentioning the ISO 21216-2012 standard, as one of the main standards dedicated to the regulation of the wireless technology and wireless networks (Behzad, 2013). The ISO focuses on the establishment of standards at the international level and maintains the control over the observation of those standards, while the violation of those standards can raise substantial problems in the international trade for violators of standards established by the ISO.The breadth of the standards regulations depends on the scope of operations of each regulatory organization. In this regard, the Federal Communication Commission focuses on the regulation of wireless standards throughout the US. As for the ISO, this is the international organization that focuses on regulation and development of international wireless standards that are applicable globally.At the same time both the Federal Communication Commission and ISO regulations and standar ds need enhancements and advancements. The Federal Communications Commission and ISO face, to a significant extent, similar problems since their regulations are, in a way, outdated because the wireless technology progresses faster than the standards are introduced by both organizations (Tanenbaum, 2013). In addition, ISO faces the problem of the introduction of such standards that would be applicable internationally that means that the ISO has to take into consideration national differences and establish standards that can be adapted in different countries.At the moment, the ISO 21216-2012 standard is one of the key standards used for wireless networks. ISO 21216-2012 standard covers the open systems interconnection layer 1 physical layer air interface for communications medium operating in the 60 GHz millimetric frequency range by providing the parameters for medium range, medium to high speed wireless communications in the ITS sector. This standard specifies the parameters require d to interface the Layer 1 of such a system to the communications access for land mobiles architecture.Along with formal regulations and standards, there are information ones, which do not have the solid legal basis but still do exist de-facto. At this point, it is possible to refer to the standard known as 802.11b. 802.11b has been the de facto  wireless networking standard of the last few years, and for good reason. It offers excellent range and respectable throughput. (While the radio can send frames at up to 11 Mbps, protocol overhead puts the data rate at 5 to 6 Mbps, which is about on par with 10baseT Ethernet.) It operates using DSSS at 2.4 GHz, and automatically selects the best data rate (either 1, 2, 5.5, or 11 Mbps), depending on available signal strength (Tanenbaum, 2013). Its greatest advantage at this point is its ubiquity: millions of 802. 11b devices have shipped, and the cost of client and access point gear is not only phenomenally low, but also ships embedded in many laptop and handheld devices. It can move data at rates much faster than the average Internet connection (Tanenbaum, 2013).Thus, the development of the wireless technology and growing popularity of wireless networks confront the problem of the poor or insufficient regulations and standardization (Viadrot, 2001). As a result, companies and individuals using the wireless technology face different risks, such as information breaches. Regulatory organizations that set standards, such as the Federal Communications Commission and ISO should unite their efforts to create a solid and effective system of standards to regulate the wireless technology and networks market.

Why They Extend Contest Deadlines

Why They Extend Contest Deadlines I have a writing friend who gets downright angry when a contest extends the deadline. He considers it an insult, or that the editors are looking for specific people who didnt make the deadline. In reality, contests are run Heres how I see it when a contest announces a later deadline for submissions: 1. The obvious. They didnt receive enough quality submissions.   Keep in mind that their reputation is based upon what they publish as a result of contest entries. So, if they extend the deadline in order to obtain better material, is that so wrong? However, if I had entered on time and saw an extended deadline, admittedly, I would interpret that as my work not being acceptable enough. Professionally, however, I see this as the contest not being organized enough to get the word out properly. Just my two cents. 2. They received fewer entries than expected.   Contests like to grow over time. When I ran the FundsforWriters Essay Contest for nine years, the submissions grew in number each year. . . such that I could not manage it any longer and write novels at the same time. That number is representative of a contests success in reaching the masses the talented writers out there. If last year a contest brought in 325 entries, and this year, a week before the deadline, theyve only received 150, something went awry. The contest doesnt want it known that the numbers dropped, so they extend the deadline. 3. They need more money to cover prize money. This reason isnt as common as one might think, but Im sure it happens. Lets say a journal promotes a $1,000 prize and publication. The entry fee is $15. The first prize figure merits a need for 67 entries to break even. Thats not considering the cost of publication and paying a judge . . . maybe advertising. Even in the world of the arts, budgets are a factor. But again, I read this as poor planning. 4. Crisis management.   You never know if something happened that sabotaged the event. Maybe the ads didnt make it out in time. Maybe the judge got sick. A sponsor may have backed out. What if the online entry form was down for a week prohibiting entries? So, you can look at deadline extensions as tricks

Education and Professional Studies Essay Example | Topics and Well Written Essays - 2000 words - 1

Education and Professional Studies - Essay Example This paper approves that The context of primary education in England and Wales in which the ideology of child-centered education is still central, it is not possible to devise any assessment task or test to be implemented by teachers, which will not be subject to very considerable contextual effects. The National Curriculum is a statement of educational entitlement to which no child should be denied. To withdraw a child’s entitlement by disapplying the National Curriculum requires strong justification. The Code of Practice on special educational needs reiterates the inclusivity of the National Curriculum: ‘Children with special educational needs require the greatest possible degree of access to a broad and balanced curriculum including the National Curriculum’. This paper makes a conclusion that one way of utilising children’s motivation for learning and of building on this is to encourage children to develop their own interests through topic- or project-based learning. The extent to which a topic approach to developing learning is motivating for children may depend on how the topic is chosen. Ways of introducing topics range from wholly child-centred to more strongly teacher-initiated. At the child-centred end are situations in which learning develops naturally from a child’s firsthand experiences. This approach requires much careful teacher guidance of children and direct teaching when the need for this is apparent. Its great strength is that it starts with the child’s interests but difficulty arises in ensuring progression, balance and breadth in learning.

Petition for a Grade course Essay Example | Topics and Well Written Essays - 500 words

Petition for a Grade course - Essay Example I not only enrolled in the class, which entails paying the fee and working to complete the course, but I also put a lot of hard work in it, which resulted in me getting an A grade. I registered in the class because my professor, Dr. Dekmejain, led me to believe that the course was a grade course. When I received the transcript, much to my surprise, the class was listed as a Credit/Non Credit Course. By this time I had completed my research, and not only that, I was hoping to get a Cumulative GPA of 3.0 with the grade that I achieved in this class. Now, as it stands, not only is my GPA going to suffer, because the class is a Credit/Non Credit course, instead of a grade course, but because of the GPA being lower than 3.0 (it stands at 2.9 now), I cannot get the job that I was hoping to get, because I will not receive the MBA diploma I was hoping to, with a GPA of 2.9. I am desperately in need of this course to get a job, as without a GPA of 3.0 I will not be able to land the job that I so desperately need. My situation is made more serious by the fact that I have a parent to support who is completely reliant on me financially and for whom I am the only â€Å"bread winner†. I would reiterate here that I would be grateful if you consider my situation with sympathy and keeping all the facts in mind (how I was misled to believe that it was a grade class, how I did well in the class and received an A, how I was relying on this course to boost my Cumulative GPA to a 3.0 to receive the diploma, how I will not be able to get a job without this diploma, and, finally, how I have financial obligations towards my parent for which I need to land this job), covert the class from a Credit/Non Credit Course to a Grade Course. I will be extremely grateful to you if you do grant my request. Once again, it is a very serious matter to me and I would be extremely thankful if you did all that you can to help me solve this

Reaching Beyond Pen and Paper :: Essays Papers

Reaching Beyond Pen and Paper Learning in school is always a given. When students are taught a subject they are eventually tested on the information learned. Most teachers use tests, handouts or papers as methods of evaluating how much a student has learned in their course. With the development of technology and the increasing amount of internet access that most classrooms have, teachers are now thinking outside the box and coming up with new ways to assess their students. Creating web pages and using online tools such as Blackboard are some of the ways teachers can have students present information they have learned. These methods are being used more often as technology grows. Though these alternative ways of assessments seem to benefit teachers, they benefit students as well. Allowing students to be more creative when completing assignments ensures their enjoyment and likelihood to do better. In 1994 Duke University’s Department of Biochemical Engineering initiated its first use of infrared (IR) networking. The classroom became completely wireless without a physical alteration to the room. Each student had to purchase a PowerBook to be able to participate in the classroom discussions and projects. The professor also had a PowerBook with a program called Timbuktu installed on it, which allowed him to access any students computer screen and project the information seen onto a screen that the whole class could see. The program also allowed the teacher complete control of the students keyboard and trackball. Through use of the IR network, the class could work on group projects more easily because they would be working though one computer. The system opened more opportunities for students to learn information effectively. For example, if a student had a problem or question about the information being learned in the class, they would simply raise their hand, the teacher would select the name from a menu bar, and instantly the whole class would see the student’s computer screen projected on the big screen. With the whole class being able to see the problem or question an individual had, they could all collaboratively help or learn from the problem. The teacher could address the question to the class and the students could help each other out. The IR network system allowed the classroom to become completely paperless. Without the hassle of handouts, research papers, and paper tests, the professor could concentrate on the information being learned by his students.

The Truth About Sharks

Yes, the dialogue was realistic which presented the realistic view of family relationships. For examples, Beth’s mum asked her to go shopping and wash the dog. Also, Beth must go to her uncle’s party that she really didn’t want to go but her mum required to go. It’s a typical view of family relationships as the son and daughter always need to listen to their parents, they don’t even have any freedoms. For me, my mum is the typical mother too. She always force me to do the thing she wants, like she asked me to study in Canada despite I truly wanted to stay in Hong Kong. What a ridiculous! Also, she is annoying too. I’m seventeen now so I’m not a kid anymore, I know what I should do or shouldn’t, but she would still ask me to sleep when it is 11p.m. only or tell me this vegetables and that vegetables are healthy but she never know I don’t like vegetables. I think she did a good job. She complained about Madge not because of the $650 gift certificate only, was because Madge offended her self-esteem. For example, she was humiliated by Madge since Madge asked her to take off the pants. I think she was a typical young adult because she had strong self-esteem, for the typical young adults, they regard money as a very important thing, just like Beth, she would try to up the price of gift certificate. Firstly, since Beth didn’t take off her pants and then walked toward other section of pants, so Madge Groton misconstrued that she wanted to steal the pants. Secondly, she had seen many kids doing this before, hence she didn’t believe what Beth’s explanation. Lastly, she wanted to do her job and she enjoyed her power of ordering the people she caught. If I were Madge Groton, I would definitely listen to Beth’s explanation since I wouldn’t know she was innocent or not. You weren’t willing to attack by the shark, you didn’t want that happen. Similarly, Beth didn’t want to accuse falsely by Madge. I think it was not a bad analogy, Madge was like a shark which meant she was cold-blooded, she ignored what Beth said and she still want to ‘eat’ her. And Beth just liked a little small fish or an innocent swimmer that couldn’t evade from the shark as it was more powerful. I think Beth was almost adequately compensated for the injustice. She could embrace the budget-free shopping, but the $650 gift certificate wasn’t enough as it wasn’t equaled to the future of Beth, she was nearly sentenced to the jail. Also, Beth won the self-esteem back from the Madge’s apology because that arrogant security guard thought she had caught the shoplifter correctly. She got empowerment on her face that money could not buy which made her feel confident.

Citizen Organizing - Free Essay Example

Sample details Pages: 3 Words: 831 Downloads: 10 Date added: 2019/04/15 Category Society Essay Level High school Tags: Citizenship Essay Did you like this example? When you live in a city, you are recognized as a citizen. From Ancient Greece, Aristotle, the father of political science, considered you a citizen if you had an active part in the states government. From the textbook, We The People, by Thomas E. Patterson, introduces the responsibilities of becoming a citizen at the beginning of the book. From this book, a couple of tips that may help enhance your feelings of citizenship and activate your engagement in the community are thinking politically and understanding the nations political culture. Political thinking is not voicing an opinion, it is critical evaluation to make political judgments on what can be believed from the information that is heard. It enhances responsibility among citizens. Thinking politically is aiming to help students, of all levels, become responsible citizens. Responsible citizenship was what English philosopher John Stuart Mill had in mind when he said that democracy is the best form of government (Patterson 2015, 3). Don’t waste time! Our writers will create an original "Citizen Organizing" essay for you Create order The citizens should not be concerned only of their rights. They should be equally alive to their duties and responsibilities. John Locke was of the view that if a man has a right to live, he has a corresponding duty not to kill others. In his words, Everyone living in the society is to obey the laws of the society. To help students understand politics, there is no right or wrong way to think politically. Everybodys understanding of politics is different. From the work of scholars, as well as political practitioners and writers have helped, political science has developed largely (Patterson 2015, 6). Tools to help broaden an understanding of politics consist of reliable information, have a general idea of major topics, and understand the terms and concepts of everyday politic conversations. The biggest obstacle citizens face in politics is the effortless act of understanding how to politically think. In this case, this shows the lack of responsibility. When citizens do pay attention, it seems as if its portrayed in an ineffective way. Many Americans get their political information and opinions, from social media and or television. It is concluded, from the University of Maryland, a study represented that the false information is universal in the talk show culture. The information from social media and television are not total lies, but the information does get twisted, as the political reporter ties in their opinion, making it sound politically correct. A journalist, Walter Lippmann, is concerned about the citizens of the United States that are unprepared to play the role democracy hands them. They live in a real world, but think in an imagined oneit is difficult to understand that citizens are in a self-governing society, but are blind to reality, Lippmann states. Lippmanns concerns have been confirmed by many scholarly studies. To continue confirming American citizens blindness to reality, one thousand American citizens were given the citizenship test that immigrants must pass in order to become a legal citizen. Four of every ten American citizens who took the test failed. With the lack of information given to citizens, that does not keep them from voting in elections, or stating their strong opinions. Most citizens are unfamiliar with their nations political stand. Again, there is no right or wrong way to politically think, but the history of the nations political stand is rarely understood. To understand where your country stands politically, it is important to know your countrys political culture. A political culture are the beliefs of its people about politics. These beliefs come from the countrys traditions and relationships of citizens to the government. There are four ideal core values of Americas culture that I learned that could help someone enhance their feelings of citizenship and activate their engagement in their community. These four values are liberty, equality, individualism, and self-government. Liberty is the act of each individual to be set free and think as they choose. A popular statement, the United States was born free, states political scientist Louis Hartz. Equality expresses the equal moral worth and treatment of each individual under the law. All men are created equal, from the Declaration of Independence, specifically from Thomas Jefferson. Individualism is self sufficiency. Americans are to remain their own masters, from Observers of Tocqueville. Lastly, self-government, is that people should have a voice in their governing and authority.
