Importance Of Note Taking In Colleges Education Essay Free Essays

Introduction Note-taking is a really of import larning tool in college schoolroom. Boyd ( 2004 ) found that pupils who take notes perform better on tests than pupils who merely highlight text. Most teachers besides wonder whether supplying press releases to pupils is truly utile for pupils or non. We will write a custom essay sample on Importance Of Note Taking In Colleges Education Essay or any similar topic only for you Order Now A study by Isaacs in 1994 shows that 43 % of academic staff frequently or ever use press releases in the schoolroom, and they feel that press releases help pupils to take notes and let them to listen and take part more in talk. The issue of note taking makes college professors use presentation package, such as Microsoft PowerPoint and its related press releases. Although Microsoft PowerPoint is more popular in colleges, it besides has negative impact on instruction and acquisition. For case, Tufte ( 2003 ) argues that PowerPoint and other presentation package have reduced the quality of presentations and represent hapless teaching method. This paper presents two surveies which determine if supplementing Microsoft PowerPoint lectures with press releases of the slides improve test-taking public presentation in an undergraduate homo development class. In the first survey, it was expected that pupils who received the press releases would execute significantly better on tests than pupils who did non. Students were surveyed about their usage of the PowerPoint press releases and perceptual experiences of the grade to which the notes helped with exam public presentation. The 2nd survey assessed the acquisition manners of pupils in order to find whether the acquisition manners with PowerPoint presentation press releases may impact pupil larning results. It looked at the three acquisition manners: lingual, visual-spatial, and bodily-kinesthetic. Method For the first survey in the autumn semester, pupils in two subdivisions of an upper degree Human Development class at a little Midwestern university participated in the current survey. Each subdivision had 50 pupils who were demographically similar across subdivisions. In the autumn semester, the class was divided into tierces, with an test given at the terminal of each 3rd. Students were required to take one of the first two noncumulative tests, but the lower class of the two was non computed into the concluding class. The concluding cumulative test was required of all pupils. At the beginning of category, Section 1 pupils were given hard-copy press releases to attach to the Power Point lectures for the 2nd test and the concluding ; they were instructed non to demo these press releases to pupils from Section 2. Section 2 pupils were given the press releases for the concluding tierce of the semester merely. In the spring survey, the process of the survey was similar to the autumn semester. However, pupils in both subdivisions were asked to look into as many points in the checklist of Multiple Intelligences Inventory for grownups ( Harper, 2005 ; Lazear, 1991 ) , wh ich characterized the ways they learned stuff. Consequences For both surveies, there were no important differences between the two subdivisions on the trial scores with the usage of the PowerPoint press releases. As clearly seen, the average test mark of the pupils given PowerPoint press releases is rather similar to the average test mark of the pupils without PowerPoint press releases. Survey Results and Qualitative Analyses Responses to the study show most pupils ( 79 % ) used the notes for analyzing for the concluding, 21 % were really attentive to the PowerPoint projections along with the notes, 25 % indicated that they had paid a batch of attending to the talk along with the press releases, and 39 % often wrote extra notes on the press releases. Similar to the autumn semester survey, the spring semester pupils were for the most portion rather positive about having the press releases, as 75 % indicated that the press releases were by and large helpful, 75 % felt that they were utile in fixing for trials, and 50 % indicated that the press releases improved their hearing to the talks. Discussion Some findings show that the function of presentation press releases is truly utile for pupils to heighten the trial public presentation, but some do non. Although the findings seem to be strong, many factors to measure the usage of this instruction technique. One factor is class content which may act upon the acquisition results in categories utilizing PowerPoint. Another is that the consequence that PowerPoint slides has on larning results is non matched by studentsaa‚Â ¬a„? intuitive beliefs. Finally, the format of press releases does non supply complete sets of notes for pupils. Future research should analyze such teacher effects in the usage of PowerPoint press releases, every bit good as whether PowerPoint slides may be more effectual for certain class content and non others. In some respects, the usage of presentation package in the college schoolroom is one of those old contentions encased in new technological wrapper. Yet, it forces those of us who are actively i nvolved in bettering instruction and acquisition in higher instruction to joint our premises and beliefs about what happens in and out of the schoolroom. To that terminal, there decidedly is something to be gained in the continued usage of the package and empirical geographic expedition of its effects. Mentions Boyd, C. H. ( 2004, May ) .

Corona Free Essays

Ingredients According to Sinebrychoff, a Finnish company owned by the Carlsberg Group, Corona Extra contains barley malt, rice and/or corn, hops, yeast, antioxidants (ascorbic acid), and propylene glycol as a stabiliser. [5] [edit]Gluten quantities Some proponents of gluten-free diets for general health or specific conditions, such as celiac disease and SIBOS (small intestine bacterial overgrowth syndrome), advise beer consumers to drink Corona because of its low gluten quantities. Bottles of Corona Extra contains less than 20 ppm gluten, while other typical beers contain well over 2000 ppm.

A draught version also exists, as does canned Corona in some markets. An explanation[citation needed] for the origin of the distinctive ‘crown’ logo from which Corona takes its name since 1925, says it was based on the crown that adorns the Cathedral of Our Lady of Guadalupe in the town of Puerto Vallarta. This cannot be, as the tower that supports the crown was only erected in 1952, the crown itself being installed at the top in 1963. 7] In Spain, the beer is branded as â€Å"Coronita† (literally, little crown), as renowned wine maker, Bodegas Torres owns the trademark for â€Å"Coronas† since 1907.

Definition and Hero free essay sample

Webster dictionary defines a hero as an Illustrious warrior; or a man admired for his achievements and noble qualities. This puts into perspective what we look for in a hero;. The last two apply to a more down-to-earth human Just as the heroes we hear about in the news or everyday people who will show these characteristics; for example, cops, firefighters, and doctors. Most people will agree with this deflation as the basic concept of a hero, but some, of course, will have a broader or more specific view on the individual.Another view off hero can be found in an extended definition. As previously mentioned, heroes can be found throughout history, many of whom have made a difference In peoples lives. They were the ones who forever made an Impact while changing the course of time with their revolutionary thinking and courage to stand up for what was right, as well as what they believed in, without regard for the consequences. We will write a custom essay sample on Definition and Hero or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page For example, Dry. Martin Luther King Jar. Dad an impact In the African-American community In the united States by standing up for African- Americans rights with non-violent protests and movements while sharing with the oral his vision of a dream, which has been memorized in his famous speech, l Have a Dream speech which says, l have a dream that one day this nation will rise up and live out the true meaning of Its creed: We hold these truths to be self- evident, that all men are created equal. Even though martin Luther King was shot and killed on April 4, 1968 in Memphis, Tennessee, his dream of racial coexistence between whites and blacks lived on and with the years, would come true. Lastly, there is the one definition that Is regarded as the highest form of truth as o what it means to be a hero, the military definition. The criteria that the military uses to identify a person as a hero is simple: it is summed up by the most prestigious military award till this day, the Medal of Ho nor, which is given to the bravest of all soldiers. According to the military, this man Is described as to conspicuously themselves by gallantry and Intrepidity at the risks of their lives above and beyond the call of duty. Many can claim the title of hero, but thanks to the military and use of this prestigious exclusive medal, it keeps the word hero from being commonplace or misconstrued. In reality, however, many think that if one Joins the military, then he Is automatically a hero In their eyes.This is because people who join the military are those who sacrifice years of their lives to serve honorably for a cause they believe in, knowing there is a possibility they will not return home. Some people whom they love, and others Join because they believe it is simply the right thing to do. Either way, many of these characteristics are well known characteristics that define a true hero. People who volunteer their time, sacrifice their lives for others, expect no imposition, and do it out of a sense of duty and selflessness, without reg ard for the possible consequences or repercussions are, by every standard, a hero. As we can see, there are many definitions and views on what a hero should be, from mythical figures with supernatural powers, to average crime-stopping cops and firefighters, to revolutionists with a righteous cause that forever changes history, and finally to war heroes who put their lives and time above others. To conclude, heroes can be defined by current events, fictional references, and military policies, but in the end, we must decide for ourselves who a hero is.

Social Media Saturated Society free essay sample

We live in a world of drones preoccupied by checking notifications on Facebook and responding to their next text message. Social media is described as electronic devices that enable communication of media, news and conversation between people. With a mounting 1. 6 billion active Facebook members as of 2013, aside from Google Facebook is the most popular website in America (Smith, 2013). Online communities such as Facebook, Twitter and YouTube are not the only thing distracting the populous. Cell phones, mobile applications and interactive gaming are just a few examples of social media in the 21st century. One cant help but wonder what kind of effects relentless participation in social media will have on our body and our mind. Our future generations are being conditioned to wake up and text until they fall back asleep. Children are spending more hours a day interacting with electronics than spending time with their family or engaging in physical activities (Hutton, 2013). Studies are proving kids growing up spending this amount of time engulfed in social-media results in less participation in the classroom and lowered grades (Hutton, 2013). Teenagers are more likely to become involved with dangerous activities such as drug abuse, drinking and sexual activity (Frank, 2010). Many may not know the negative impact social media can have on ones health and the astonishing new findings actually state it may be altering the way our genes work (â€Å"Online networking harms health,† 2009). Studies are proving that spending too much time sucked into social networking is hazardous to the well-being and growth of adolescents; therefore parents need to limit how much time their children are hypnotized by social media. It would seem, with hundreds of Facebook friends, people would have an abundant social life, but surprisingly it is the exact opposite. Dr Sigman, who has a Bachelor of Science degree in Psychology, a Master of Science degree in The Neurophysiological Basis of Behavior, and a Ph.D. in the field of the role of attention in autonomic nervous system self-regulation studies how social media is effecting people today. His results went beyond people creating isolation stating, â€Å"lack of face-to-face networking could alter the way genes work, upset immune responses, hormone levels, the function of arteries, and influence mental performance† (â€Å"Online networking harms health,† 2009). These findings indicate our current social media addiction may be causing biological side effects. Dr. Sigman also found shocking information stating people who are media-dependent, â€Å"could increase the risk of health problems as serious as cancer, strokes, heart disease, and dementia† (â€Å"Online networking harms health,† 2009). Most people have no idea the dangerous health concerns that Dr. Sigman brings to light. Social media is booming like never before, and the majority of Americans are at risk for these negative effects. A large amount of the people in the United States that participate in social media are teenagers and children. A website that was made for family education is coming fourth with astonishing information, broadcasting that children are spending more time involved with social media devices than spending time with their family, being in school, or even sleeping. The article reveals,In just five years, media use has increased from 6 ? to nearly 7 ? hours a day in children between the ages of 8 and 18. Even more alarming children have become master multitaskers, often using two or more media devices at the same time. Counting each device separately, these kids have found a way to cram in a total of 10 hours and 45 minutes of media content into those 7 ? hours. (Hutton, 2013, para. 3) That is seven hours that could be spent reading books, engaging in real face to face communication with their family, or running around outside using their imagination like generations before this media craze began. These â€Å"media saturated† children are also having this phenomenon negatively impact their grades in school. â€Å"Almost half of the children in the survey who were considered heavy media users had grades of mostly Cs or lower† (Hutton, 2013, p. Parents need to limit the amount of time their children spend using the computer, playing video games or any other electronic device. If parents allow their kids to continue overdosing on social media it will not only effect their education, it could also change their satisfaction with life and consequently their behavior stemming from those inadequate feelings. The same website created for parenteral education that explains how social media is becoming detrimental to students grades continues to share it is damaging kids ability to feel fulfilled. FamilyEducation. com informs readers, â€Å"kids who spend more time with media devices reportedly have a lower level of personal contentment, and have a tendency to get in trouble more often. They also reported feeling more sad or bored than their non-media-obsessed counterparts† (Hutton, 2013, p. 1. ) Young minds that are addicted to media devices could be feeling unenthusiastic about life and not even understand why. Maybe this is why studies are linking dangerous actions, such as suicide, to social media-dependent teenagers. A term new to some, â€Å"hyper networking† describes spending more than three hours on social networks per day and â€Å"hyper texting,† which means texting more than 120 text messages per day. In 2010 Case Western Reserve School of Medicine study showed, â€Å"correlations between unhealthy behaviors in teens, including drinking, smoking and sexual activity† (Frank, 2010. ) When teenagers spend more time captivated by sites like Facebook they are gaining access to people older than them, and with that comes more exposure to dangers such as substance abuse and drinking. The study also concluded â€Å"Hyper networking was also associated with depression, substance abuse, poor sleep patterns, suicide and poor academic performance. † Remember poor academic performance and feelings of sadness were also reported in children that were spending hours a day removed from real-life interactions. It is up to parents to protect and nurture their children as their mind and bodies develop, so limiting how much time is wasted lurking on sites like Facebook is essential. Many parents are completely ignorant of the unfavorable effects of social media. Parents need to be informed of the enormous increase in likelihood that teenagers would engage in these self-destructive activities. Teens who are hyper-networkers are 62 percent more likely to have tried cigarettes, 79 percent more likely to have tried alcohol, 69 percent more likely to be binge drinkers, 84 percent more likely to have used illicit drugs, 94 percent more likely to have been in a physical fight, 69 percent more likely to have had sex and 60 percent more likely to report four or more sexual partners. (Frank, 2010, para. In all statistics conducted there was at least a 60% increase in the chance of a teen partaking in these harmful activities that, for some, will form into habits. Minors are naive to all the dangers of social media. It is the responsibility of parents to filter what their children are exposed to and alter the amount of time spent interacting in social networks. Speaking of naive, I have a little sister who is socially underdeveloped for her age. When I was in middle school the only way I could talk to my friends was through real face to face interaction or calling them on the telephone. Those circumstances forced me to learn social skills and communication. My younger sister, on the other hand, barely has any friends and spends days in isolation playing games or spending time on sites like Facebook. She already has issues with self confidence like most young girls, and being in the bubble of social media seems to enable her even more. She has always struggled in school with reading and writing. I am positive if she would have spent more time outside or practicing her grammar and exploring literature she would not only have a different experience in school but also a greater self-confidence. Changing how upcoming generations engage in social media would have a impact on how healthy our future adults are mentally and physically. That impact could be negative or positive based on the duration of time devoted to social media and how dependent on that interaction they are. There are some positive aspects of social media like staying connected with family or friends and outsourcing of information like the news. America is still at war and some families have members overseas. They rely on the use of programs like Skype to stay connected. Others have claimed to find the love of their via use of internet access. While not all use of social media is negative, in regards to nurturing our children it is still essential to limit their interactions with social media. Kids growing up in this era of social network overload spend most of their days pushing plastic buttons instead of turning book pages. Children are being effecting by the overuse of electronics from their grades in school to feeling depressed and unsatisfied (Hutton, 2013, p. 1. ). Parents need to be in control of their teens internet usage, and monitor who they are interacting with and how much time they spend dazed in front of computer screens. Teenagers are more likey to regress by par taking in self-destructive activies such as binge drinking or smoking if particiating in hyper texting or hyper networking (Frank, 2010). New research has shown too much time spent in isolation due to social networking is negatively effecting peoples health and might even be altering our genes (â€Å"Online networking harms health,† 2009). Not all use of social media is bad, but limiting the amount of time spent frivolously playing online is of the utmost importance to our up coming generations.  Social networking in abundant amounts is clearly disruptive to adolescents health and development. Parents have the power to break their childrens addiction to social media so that they may transcend and prosper into healthy, well rounded, happy individuals.

Julus Caesar - Analysis Of Caesar Essays - , Term Papers

Julus Caesar - Analysis of Caesar Essay on Caesar In Shakespeare's play of "Caesar" Brutus is a conspirator who portrays a person who favors a republic for Rome. Brutus is an honorable man. Many characters in the play show there reverence for Brutus. Brutus exemplifies his honor in many ways. Brutus is obsequious when he is needed to abet his fellow romans. Brutus is an honorable man. "Am I entreated to Speak and Strike? O Rome I make thee promise, If the redress will follow, then receivest thy full petition at the hand of Brutus" (Shakespeare 397). Brutus will obey to whatever the romans convey to him. Consequently, Brutus joins the conspiracy inorder to help the romans rid rome of Caesar. Brutus also understands that he is putting it all on the line for his romans, therefore Brutus is an honorable man. Brutus is a scrupulous man, whose virtues endure. "No not an oath, If not by the face of men, the sufferance of our souls, the time's abuse-If these motives be weak, break off betimes, and every men hence to his idle bed; So let high sighted tyranny rage on, till each man drop by lottery" (Shakespeare 399). Brutus said that if the conspirators do not join for a common cause, then there is no need for an oath because the conspirators are self-righteous, and they are serving the romans. If the conspirators don't bind together, then each man will go his own way, become a weakling, and die when it suits the tyrants caprice. Brutus is advocates peace, freedom and liberty, for all romans, which shows that Brutus is an altruistic as well as an honorable man. Brutus also had a compassion for Caesar when he had killed Caesar. "If then that a friend demand why Brutus rose against Caesar, this is my answer: Not that I loved Caesar less, but that I loved Rome more" (Shakespeare 421). Brutus had honored Caesar but Brutus felt that Caesar was to ambitious. Brutus also felt that Caesar made the romans as slaves. Therefore, Brutus is an honorable man. Brutus is a noble man who was revered by many. Brutus had j oined the conspiracy because he had the desire to help the commoners. He was a follower of idealism, where the romans would possess peace, liberty and freedom. Brutus wanted the kill Caesar, because he believed that all of the people of Rome would eventually be slaves, thus Brutus resorted to the assassination if Caesar. Brutus is a honorable man. Marcus Brutus was a good friend to Julius Caesar, but not good enough. He had moral values dealing with Rome and its people. Brutus' values then made him join a conspiracy against Caesar put together by Cassius. Brutus joined this mainly because he didn't want Caesar to turn his back on Rome so there would be a reasonable reason for killing Caesar. If Brutus wasn't in the play, there would be no "Tragedy" in The Tragedy of Julius Caesar.

Projectile range and projectile motion Essay Example

Projectile range and projectile motion Paper As we all know ski jumping is a worldwide sport in which athletes skate down a slope ramp, gaining speed that throws them in the air that makes them land some distance away. The distance travelled at the time when the jumper leaves the ramp, until he reaches the ground is known as the jump range. This interesting and challenging sport involves a lot of physics behind it. Kinetic energy, gravitational potential energy, motion, speed, height, time, distance and the athletes ability to reduce air resistance to their body are all factors that determine the athletes performance. This experiment represents a ski jumping slope through which we will investigate and demonstrate how physics can be used by ski jumpers to increase their range in the jump. Aim: My aim of this experiment is to explore the relationship between the launch height and the range of the jump. I will use the my knowledge of physics knowing that gravitational potential energy can be converted into kinetic energy and using the equations ? Egrav = mg? h for gravitational potential energy and Ek = 1/2 mv2 for the kinetic energy to work out the relationship between height, velocity and the range of the projectile.

Null Hypothesis There will be no relationship found between the height of the ramp, velocity and the range of the projectile. Rationale The displacement, velocity and acceleration of the projectile are all vectors. The forces of the projectile motion can be treated separately, so they can be resolved into horizontal and vertical components. They are independent of each other; that is, neither motion affects the other. We can label these components x and y. The horizontal component can be represented as Vx and the vertical component as Vy. Vx = V cos ? Vy = V sin ? The projectile/ball baring will be dropped from the top of the ramp giving the projectile gravitational potential energy. We can work out the gravitational potential energy by using ? Egrav = mg? h as we know the mass of the projectile, gravitational effect and the height at which the projectile is launched. As the projectile travels down the ramp it will be affected by air resistance and friction, however in this experiment we will ignore these factors. The point at which the projectile starts moving down the ramp, the gravitational potential energy converts into kinetic energy allowing it to accelerate off the ramp and into the air. We can use the equation Ek = 1/2 mv2 to work out the kinetic energy. Ignoring air resistance and friction, we know that the gravitational potential energy at the top of the ramp will equal the kinetic energy when it leaves at the bottom. This experiment involves me looking at the relationship between the height and the range of the projectile. In theory by changing the height I am changing the velocity of the projectile and so therefore the range will be affected. By re-arranging the equation Ek = 1/2 mv2 we can work out the velocity of the ball baring, 2Ek/m = v2 then do V v2 = v. This can also be simplified to give V (2mgh) /m = v. The m cancels which will leave us with V = V (2gh). We can then use the equation V = Distance/Time which will give the theoretical horizontal value. We can re-arrange this equation to give us the distance, Distance = Velocity x Time. This is the horizontal component. Changing the vertical height of the drop from the ramp would vary the range. This is because according to the law of energy, it cannot be made or destroyed but transferred. To apply this law into this practical, we can say all of the gravitational potential energy is converted into kinetic energy assuming no energy is wasted. As a result, gravitational portential energy is equal to kinetic energy.

How a hit almost failed its own audition Essays

How a hit almost failed its own audition Essays How a hit almost failed its own audition Essay How a hit almost failed its own audition Essay Bill Carter, in an article that is to be published in the book Desperate Networks, tackles the fact that television networks need to find hit shows to be able to survive. Because of this, they can be very thorough in examining potential programs and may sometimes almost forego program proposals because they do not sound potentially popular with viewers. This was what happened with Fox Network’s American Idol. In the article â€Å"How a hit almost failed its own audition†, Carter tells of how the now-famous reality show American Idol encountered difficulty in breaking through in America. Despite the fact that its creators Simon Cowell and Simon Fuller are well-versed in the music scene and are even pretty popular in Britain, their idea bombed out in America. Cowell and Fuller, when proposing Pop Idol in Britain, had little to no obstacles because of their credentials in the country. And Cowell’s proposal in Britain seemed to have sparked a lot of interest: this music format is to be as much a talent search as a soap opera. Basing on the success of former talent search-soap opera amalgamated shows like Pop Stars, British network ITV was immediately sold to the idea. Yet crossing over to America proved to be problematic. As was outlined in the article, it could have been easy to peddle well-known British reality shows to America because of the tremendous success of British-produced Who Wants to Be a Millionaire and Survivor and because reality programming is â€Å"light, entertaining and not very expensive to produce†. But Pop Idol (soon to be American Idol) had one big barrier to overcome: the fact that music reality shows have previously failed in America. Having endlessly met the unenthusiastic response of American network executives regarding the American version of the hit British reality show Pop Idol, Cowell almost seemed ready to give up. He was, as Carter said, already answering network executives with â€Å"a dash of acid†. But Fuller was not going to throw in the towel. Going to Fox, he pitched Pop Idol â€Å"with fervent passion†, saying that the show will â€Å"essentially be all audition†. This seemed to have gotten the attention of Mike Darnell, Fox’s reality division head; after all, the only part of band-making shows that he liked was the auditions. But even this positive response was not to signal American Idol’s birth. The show’s creators are still to be haunted by Fox’s demands for the program to come attached with sponsorship. Perhaps American Idol would have taken more time before its successful take-off if Creative Artists Agency (C.A.A., which represented Fuller and helped him get Pop Idol in America) did not pull some strings. In a meeting with Elisabeth Murdoch, daughter of News Corporation (which owns Fox) founder and chief executive Rupert Murdoch, C.A.A. executives mentioned how Pop Idol is being stalled in Los Angeles. Having witnessed the program’s success in Britain and genuinely loving it, Elisabeth Murdoch immediately called her father and convinced him that Fox should buy the program’s rights. And the rest, as they say, is history. American Idol had a rough start, proving that what is already popular in another country will not necessarily be sold easily in another – there are, in fact, other important factors to consider. In Idol’s case, the history of like program formats worked to its disadvantage. Yet the show also demonstrated how, at times, flexing some muscles and forging good business relationships are really advantageous to one doing business. Had it not been for C.A.A.’s initiative to ‘use’ their connection with Elisabeth Murdoch, American Idol may have not found its American home as soon as it did. And now, Fox have under its belt, one of the most famous American shows to ever hit TV – and to think, it had been rejected by numerous TV networks in April of 2001.
