Geometry and Measurement Essay Example for Free

Geometry and Measurement Essay Measurement refers to the estimation of the magnitude of some attribute of an object, such as its length or weight, relative to a unit of measurement (Measurement, 2008). It usually involves using a measuring instrument, such as a ruler or scale, which is calibrated to compare the object to some standard, such as a meter or a kilogram. In science, where accurate measurement is crucial, a measurement is understood to have three parts: first, the measurement itself, second, the margin of error, and third, the confidence level that is, the probability that the actual property of the physical object is within the margin of error.

When one is tasked to measure a specific unit, one is expected to acquire the most accurate data possible. Be it length, area, weight, volume or time, there are different modes of measuring processes designed for each classification of measurement so that all data acquired would be correct and appicable to all. Whatever kind of measurement you are trying to get, there should be a universal standard that should be used so that it can be used and applied by everyone. This helps in the consistency of measurement and the validity of the data. The van Hiele levels of geometric reasoning is a measuring stick to determine how advanced a persons thinking is in terms of geometric figures and objects. By using these levels, one can evaluate the progress of any person in learning about geometry and the concepts behind it. In the first level, known as visualization, students can name and recognize shapes by their appearance, but cannot specifically identify properties of shapes. Although they may be able to recognize characteristics, they do not use them for recognition and sorting. The second level, called analysis, students begin to identify properties of shapes and learn to use appropriate vocabulary related to properties, but do not make connections between different shapes and their properties. Irrelevant features, such as size or orientation, become less important, as students are able to focus on all shapes within a class. And in the third level, known as informal deduction, students are now able to recognize relationships between and among properties of shapes or classes of shapes and are able to follow logical arguments using such properties (Van de Walle). When one is faced with having to deal with fellow students who have differing geometric levels, one has to understand a couple of things. First, one cannot expect other people to be at the same level as you. We all have different levels of intelligence, or perhaps have a different pace in terms of learning new concepts or ideas. When someone is less advanced than everyone else, this does not automatically mean that he is less intelligent than the others. Several factors could have played a role, such as the unfamiliarity of the person towards geometric concepts. Those who are at a lower level could easily move on to the next, provided they are guided appropriately by those who are knowledgeable of the subject. Likewise, those who are more advanced than others need not feel that they more superior than their peers. They could simply have just been more familiar with geometric figures, perhaps having encountered them already in previous occasions. In the end, it is still the progress of everyone that should be the main concern, rather than focusing on individual achievements. References Measurement (2008). Annenberg Media.

Matewan: A John Sayles Film :: Economy Economics Movies Essays

Matewan: A John Sayles' Film John Sayles, the writer and director of the film Matewan, demonstrates an understanding, albeit possibly an unconscious one, of the struggle between two economic systems. This work depicts the historical events of 1920 in the Mingo County, West Virginia town of Matewan, a place that came to be known as "Bloody Mingo". Although many people are accustomed to viewing feudalism as a social system from the past, history is not such an orderly, linear progression of societies and ways of life but is, rather, a dynamic, chaotic process. Therefore, it should come as no surprise that in the 1920s in this part of the United States there was a clash of two different economic systems—capitalism and feudalism. Economic systems are attempts to solve the following questions: Who does the production? Who controls the profits? And what is the social arrangement by which the two previous questions are resolved? There is an interlocking triad of considerations: economic relationships; political relationships; and cultural relationships. We see these relationships brought to life in the events of Matewan. Feudalism exists when free people have to work for a single employer, or not work at all. Capitalism, in contrast, allows free people to choose their employers. There is often in history a struggle between feudal and capitalist structures. The story of the coal miners is the story of one such clash. The Stone Mountain Coal Company owns everything in the town of Matewan. Its owners, the economic elite, could be likened to a collective feudal lord presiding over the estate of Matewan. Theirs is the only game in town and the miners have no choice in where they work This monopoly is feudal because of the absence of free choice. Capitalism requires competition over capital, not just capital. The total lack of competition is exposed in the train scene. The new men are told that they are beholden to the company for expenses—their tools, their train fare, tool sharpening, and even their fuses, caps, and powder. What little pay is left over is issued in company scrip, which is only good at the company’s store. We, the audience, are told at the onset of the film that the pay rate per tonnage has just been lowered. The company’s grip is vise-like; it can charge more and pay less. This combination is the scissors effect, and it leaves the miners in a subservient positio n.

Essay on Psy201 R6 Research Plan - 643 Words

University of Phoenix Material A Research Plan Part I – Research Problem Think about something in psychology that you would be interesting in studying. You can select a topic from what you’ll be studying in this course or another topic that seems intriguing to you. Respond to the following in 50-75 words: Identify your research problem and describe it. What about this topic interests you? The research problem is what causes stress. I will discuss the cause and problems of stress on the body. I will discuss how stress can affect the body and how they correlate with each other. This topic interests me because many people will say I’m so stressed out. But why and how stress affects the outcome of a situation is still unknown. In†¦show more content†¦Be sure to go over each step of the scientific method in your response. Formulate a testable hypothesis. For this study, I have to define my hypothesis as, â€Å"Are stress and health related, in such a way that health decreases as stress increases?† Hypothesis are statements about what will happen in any give situation; if my observations do not match my prediction, the hypothesis will be rejected. Step 2: Select the research method and design the study. - consider how to best test the question. There is no â€Å"best† research strategy; each design has its advantages and disadvantages. Who I available to participate I the study? Where should the study take place? How should the behaviors be measured? Psychological researchers test their hypothesis in ways that represent the real-world environment; their question, or hypothesis, has to have meaning, I am not a psychologist, so I will not be testing my hypothesis within a laboratory. In the report of the methods used in a study, information is given so that someone else can reproduc e the same circumstances I did. For this reason, I have to be careful in conducting my study. Step 3: Collect the data- The researchers approached more than 100 people (men, women, and children) waiting until they would mind answering a few questions or taking a survey for a psychology study. Step 4: Analyze the data and draw conclusions. - The ratings provided by the participants were grouped by gender, age, adult and child.
