A reliable instrument is one that is consistent in what it measures. If, for example, an individual scores highly on the first administration of a test and if the test is reliable, he or she should score highly on a second administration. Imagine that you are conducting a study for which you must develop a test in mathematics for 7th-grade students. You develop a 30-point test and distribute it to a class of 12, 7th-grade students. You then administer the test again one month later to the day. The scores of the students on the two administrations of the test are listed below. Use Microsoft® Excel® or IBM® SPSS® to create a scatterplot with the provided scores, formatted as shown in the example graph. What observations can you make about the reliability of this test? Explain.

Watch the video Merchants of Cool at http://www.pbs.org/wgbh/pages/frontline/shows/cool/view/ After watching the video or reading the article, respond the following questions. (Must be a minimum of 400 word response)

 

How, and to what extent, does the mass media influence the public’s attitudes and behaviors? Do television shows and newscasts, for example, simply reflect what is happening in the world or do they carry the potential to actually cause real-life events? Apart from advertising, do you believe the members of the media engage in deliberate attempts to persuade people to adopt certain opinions and attitudes?

 

 

 

Question 8

 

Previously we have discussed many of the pros and some of the cons of Montessori education. If any of you have personal experience with the Montessori Method, please comment upon it here. Based upon what you now know about child development, can you think of any particular type of child for whom Montessori would not be a good fit? Are there any empirical data available to help answer this question (e.g., which children are suitable for a Montessori education)?  Do a little research on your own to see what the experts think and then form your own opinion.
