Signing Miracles essays

Signing Miracles essays When one door of happiness closes, another opens; but often we look so long at the closed door that we do not see the one which has been opened for us. (Helen Keller) This is one of many quotes from the play The Miracle Worker, which was performed at Highlands Ranch High School on January 21, 2005. The play was a tragic story of a young girl growing up deaf and blind. It took place during the nineteenth century. The play story revolved around Helen Keller, the young girl, and the difficulties of learning without sight or sound. The production of The Miracle Worker seemed on average a pleasing experience for the audience. All lines by the cast were well memorized and hardly any mistakes were noticeable. Sound and music could not have been more appropriate. The only thing that seemed lacking was lighting and the over exaggeration of a particular character. This character talked as if she were a woman of little intelligence and disrupted the realization. All actors were taught very well on sign language and brought a certain recognition to the well know play. The actors reacted to each other very appropriately. In one scene an actress said her lines in the wrong order and the other actors played it off as if it was supposed to be this way. Everything has its wonders, even darkness and silence, and I learn, whatever state I may be in, therein to be content. (Helen Keller) The theme of this play was through darkness and silence learning is an adventure. Where darkness and silence are, happiness always prevails. ...

Becoming a teacher of English in Thailand Essay

Becoming a teacher of English in Thailand - Essay Example Even the globalization has filed to make any huge impact on Thai people’s attitude towards English. English is not recognized as a status symbol in Thailand and hence it is not a compulsory subject in Thai schools. This article also provides a research study about the lives and careers of the Thai teachers of English. The research has been conducted through interview methods and the researchers interviewed seven Thai English teacher for around 3.5 hours to collect data. The research has shown that the experience of schooling has an immensely powerful effect on children, for better or worse, and that often these effects last well into later life. The research also revealed that positive experiences not only make schooling enjoyable in its own right but can often plant the seeds which lead children at school to consider teaching as a career in later life. Active teaching styles of the Thai English teachers also influenced the interviewees to opt for selecting teaching English as their career. Social, cultural and family reasons also forced these teachers to select their teaching career. (Hayes, n.d) Teaching is a stable profession with job security in a world where the changing trends in business has resulted in many people losing their jobs. The current economic crisis has affected millions of peoples around the world and many people are living in anxiety or fear of losing their jobs. But teaching is found to be one profession which is not affected by the current crisis. Nobody can underestimate the value of teaching even in a crisis scenario and hence teaching is supposed to be one of the most reputed professions in the world. As government servants, teachers had considerable job security and other benefits, which were emphasized nursing or teaching, seemed to be the choices for those who wished to continue their education close to home (Maum, 2002) â€Å"Many non-native-English-speaking teachers (NNESTs),

Teenage pregnancy and its consequences Research Paper

Teenage pregnancy and its consequences - Research Paper Example Discussing the actual incidence of teenage pregnancy in both eastern and western societies along with identifying the major horrific consequences this issue produces, while taking care to mention how differently those particular consequences are perceived in the eastern and western societies form the bulk of this paper. Introduction: Granting appropriate rights to teenage mothers is not a facility entertained in many countries even in the present world since much hatred and conservatism exist towards the issue of teenage pregnancy especially in the eastern world where even discussing this critically sensitive issue is considered and perceived more like a social taboo. How the overall intricate and worse situation produced by teenage pregnancy can be overturned by granting proper and officially approved rights to the teenage mothers can change the dramatic situation brought on by this issue is a debate much worked on by many scholars and sociologists. Moreover, child abuse, neglect, a nd poor parenting are important negative outcomes of teenage pregnancy and are shown towards children born to teenage mothers, thus forming a grave consequential problem produced by teenage pregnancy (Britner & Reppucci, 1997, p. 165). This serious issue raises much concern for the upbringing of young children who have to become responsible citizens later in the future. This also remains a plausible reality that the incidence of teenage pregnancy is much higher in the western world in comparison to the eastern world and valid reasons backed up by research reports for explaining this difference in teenage pregnancy incidence also forms a part of discussion contained in this paper. Thesis statement: Facts and discussion presented in this paper are basically meant to illuminate the reality of the claim that â€Å"teenage pregnancy is an issue perceived differently and while the teen pregnancy has a higher incidence in the developed world, the severe consequences produced by this grave issue are better handled in the modernized western society than they are in the more conservative undeveloped countries.† Incidence of teenage pregnancy in the western world: The fact that the risk of teenage pregnancy in America is twice that of any other industrialized country presents a scenario which is both increasingly grave and attention-demanding and illuminates the profound need to raise awareness about the sexual caution measures which the teenage girls should be familiar with in an order to avoid the risk of pregnancy. â€Å"Available national survey-based information for the United States shows that 78% of all pregnancies and 66% of all births to adolescents in the early 1990s were unintended† (Henshaw, 1998, p. 24). Teenage girls are certainly less mature and sensible to take care of their children in an appropriate way which is one of the reasons why reducing teenage pregnancy is highly important. This sad reality also illuminates the prevalence of promis cuous behavior among teenage girls in USA which has increased over time, thanks to an increase in the party culture and sexually explicit material very often presented in a highly glamorous manner on various television channels. It is understandable that getting pregnant due to carelessly engaging in dangerous sexual activities and one night-stands can rob the young women of their education, respect, and family support. A terrible hand-to-mouth existence awaits for such teenage mothers who obviously cannot depend on their partners for

Calculating Free Fall Acceleration

Calculating Free Fall Acceleration Introduction A research by Heckert (2010) shows in 1600s, the famous physicist Galileo . Galilei found the swinging motion of a large chandelier in the Pisa cathedral. He began to seriously analyse the chandelier, and recorded the time the light took to swing. In the 16th century, there was no stopwatch so that Galileo timed the swing by pulse. In addition, he was the first European to really study this phenomenon and he discovered that their regularity could be used for calculate the local gravity. For Galileo his pendulum was the light but generally speaking a pendulum can be defined as a body suspended from a fixed point which swing freely by the motion of gravity and momentum. It is used to regulate the movements of clockwork and other machinery. In its simplest form and avoiding the math there are three parts to the basic laws of a pendulum. First the time for each oscillation is depending on the length of the strings. In addition, mass of the bob does not affect the motion at all. Second, a pendulums horizontal speed is the same as the vertical speed would be, if the bob had fallen from its highest point. Thirdly, the square of period of the bob is inversely proportional to free fall acceleration and the square of period of the body is proportional to length of the pendulum The background definition and the laws of a pendulum can be used to calculate the free fall acceleration. Using a simple gravity pendulum like Galileos Pendulum System, I would like to show how to find the best ways in order to test free fall acceleration. Methods 1. Experiment equipment: Protractor Steel Bob Stopwatch Vernier Caliper Iron Support Stand Meter Ruler Inelastic String 2. Apparatus setup Figure1-1 Figure1-1 shows that iron support stand was put beside edge of test desk in case the height of stand was shorter than the length of test string. Next, the steel ball was hung by an inelastic string and the iron support stand was used to support the weight of steel ball. Last, the clip was clamped to the string in order to keep a constant length. At the same time, the bob swing in a vertical surface which parallels the stand. 3. Procedures First of all, the simple pendulum was made up by hanging a bob from the top of stand and the bob was released in a constant height, then protractor was used to control the degree between 5 and 15 to normal line. Secondly, pendulum would begin to oscillate in vertical surface in a regular action, and then the stop watch was used to record the time of each swing. Finally the most important data which describes this oscillation is period and we did different types of test by different length of string, like 30cm, 45 cm, 60 cm, 75 cm, 90cm, 105 cm, and 120 cm. Results Table of result Experiment times Length of string (cm) Trials: 1 Trials: 2 Total Average period Oscillationtimes Average period of each swing T2 (second square) Time taken for one complete Oscillation(seconds) 1 30cm 56.60s 56.50s 56.55s 50 times 1.13s 1.28s2 2 45 cm 68.60s 68.50s 68.55s 50 times 1.37s 1.88 s2 3 60 cm 79.00s 78.90s 79.00s 50 times 1.58s 2.50 s2 4 75 cm 87.60s 87.90s 87.75s 50 times 1.76s 3.08 s2 5 90 cm 96.05s 96.00s 96.05s 50 times 1.92s 3.69 s2 6 105 cm 104.00s 104.00s 104.00s 50 times 2.08s 4.33 s2 7 120 cm 110.50s 111.00s 110.75s 50 times 2.22s 4.91 s2 Table-1.1 Table-1.1 shows the data of 7 experiments using different length of string and how the data changed, as the length of string was increased; the period of each oscillation was increase as well. L is the distance from the frame of the stand to the center of the mass; the length includes the radius of ball. The period of oscillation is the time required for the pendulum to complete one swing. For one complete swing, the steel ball must move from the left to the right and back to the left. T2 can be understood as the square of the period of oscillation, the equation below shows how T2 was calculated. Square both sides: T2= 4 Ãâ€" Ï€2 Ãâ€" (L/g) T2 = L Ãâ€" (4 Ãâ€" Ï€2 à · g) Multiply both sides by g g Ãâ€" T2 = 4 Ãâ€" Ï€2 Ãâ€" L Divide both sides by T2 Discussion and Analysis The results of experiment show the relation between T2 and length of string. To turn to discuss the results it is important to understand some key ideas, there are controlled variable, experimental variable, error and uncertainty. Firstly, according to Science Buddies(2009) said that a controlled variable can be defined as the factor which is unchanged or kept constant to prevent its effects or error on the outcome. It was verified the behavior of the relationship between independent and dependent variables. The factors which can be regarded as controlled variable were steel ball, oscillation times; the angle of each swing and the height when the steel ball was released. An answer from wiki (2009) the definition of experimental variables is the variable whose values are independent of changes in the values of other variables. Experimental variable in this experiment is the length of string. According to dictionary the error can be defined as a deviation from accuracy or correctness. And the uncertainty means that the lack of certainty, a state of having limited knowledge so that it is impossible to exactly describe existing phenomenon or future outcome confidently.Errors were caused by any individual who could be affected by many factors. Such as before we measure the length of string, we need to measure the radius of ball by vernier caliper in case the string is shorter than actual length. Secondly, we need to take care of how much oscillation times we did. Thirdly, we need to keep the pendulum swing in a same surface in case the extra energy was wasted. At last, taking more time measurements of experimental variable which is length of string may be more accurate average for each trial. Find two point from the graph A(x1, y1) B(x2, y2), use the formula (y2-y1)/(x2-x1) the result of gradient is 4.03. The table shows the results of free fall acceleration Gradient(T2/L) 4.03 Calculate data in using formula G 9.79ms-2 Confines of Error 0.22% Table2-1 To summarize the weakness that is error and uncertainty and calculating the acceleration of gravity to within 5%, and table 2-1 shows that the experiment obeys the allowable confines. Confines of Error were calculated by the difference between actual gravity and what I got, and the values were divided by the actual values. Conclusion To sum up, the calculation of Galileo that free fall acceleration from the formula, this can infer the result of free fall acceleration. I need to compare the calculation of Galileo which free fall acceleration should be 9.81ms-2. In fact, a gravity pendulum is a complex machine, depending on a number of variables for which we are ready to adjust. In addition, firstly we try to understand the method that Galileo did in 1600s, and making a plan to have a complete the system. Then form the data I found some different values about gravity, and the factor to influence the values. The main factor is that the different length of string influence the period instead free fall acceleration, the period square and length have a constant ratio to calculated the acceleration. Turning to Dohrman, P (2009) it can be argued that the factors which influence the fact are length of the string, period of each cycle by using those two factors we can get the local gravity. All above those factors can influence the values of free fall acceleration, and we got the less number than actual values. I need to take care of them and have an improvement. For instance, first difficulty is that measuring the length is deciding where the centre of the bob is. The uncertainty in determining this measurement is probably about 1 mm. Secondly, the stopwatch measures to 50 of oscillation although the overall accuracy of the time measurements may be not certain. According toDohrman (2009) the human reaction time to start and stop the watch has a maximum range of 0.13 seconds and the average is0.7. Finally, 9.79ms-2 was calculated by the gradient and the formula in part of result.

Symbols and Symbolism in The Yellow Wallpaper and A Rose for Emily

Symbolism in The Yellow Wallpaper and A Rose for Emily      Ã‚   William Faulkner's "A Rose for Emily" and Charlotte Perkins Gilman's "The Yellow Wallpaper" hold numerous similarities. Both stories show the influences of society and the slow decay on a particular woman. The title of each piece becomes important to the plot and ultimate outcome. In several ways, each title takes shape to portray symbolism in one sense or another. The references to color identify contradictory messages to those who have not heard of these stories, while the title itself takes physical form and is "living" at some point in the piece.      Ã‚  Ã‚  Ã‚   When first assigned to read "The Yellow Wallpaper," a student may think of a bright, cheerful paper covered room. Little does he realize that, instead of a stereotypical yellow, the wallpaper's "color is...almost revolting; a smouldering unclean yellow" (Gilman15). It reminds the narrator of "all the yellow things [she] ever saw--not beautiful ones... but old foul, bad yellow things" (23). According to Carol Westcamp, "the author designed the wallpaper...to be yellow for a reason" ("Smouldering"). Even though "yellow is often viewed as a cheerful, joyful color...[it] can also cause unpleasant, exciting, and hostile moods due its symbolism" (Westcamp). The wallpaper takes on a distinctive odor that " 'creeps all over the house,' drenching every room in its subtle aroma of decay" (Gilbert 35). The only thing the narrator "can think of that [the smell] is like is the color of the paper! A yellow smell" (Kivo 23). The narrator feels herself being drawn closer to the brin k of insanity by the maddening color and begs her husband to do something about the paper, but he simply laughs at her.      Ã‚  Ã‚  Ã‚   As the... ...apy.
