Mr. Jacobs wants to find out whether a new program for teaching physical education promotes students’ physical development. He g

ives his students a number of tests before they begin the program (pretests) and the same tests again after they have been in the program for eight months (posttests). He finds that the students’ posttest scores are higher than their pretest scores and so concludes that the program is effective. What is definitely wrong with Mr. Jacobs’ conclusion? a. Eight months is too short a time for such a program to have a long-term effect. b. There are other possible explanations for his results. c. Tests are not a good measure of physical development. d. The posttests should always be different from the pretests

Answer:

The correct option is letter B. There are other possible explanations for his results.

Explanation:

One possible explanation for the results, for instance, is the fact that all the students have already taken the same tests before. It is okay to use the same tests again but, since students already know it, they could figure out a way to do better this time. For Mr. Jacobs to be sure of his results, he should have divided his students into two groups. One group would train according to the new program and the other group wouldn't. They would be tested and have their results compared. If the experimental group - the one that used the new program - did better than the control group, then Mr. Jacobs could conclude the program works.

Answer:

c. gender roles

Explanation:

In psychology, the term gender roles refer to the values and behaviors that society things are appropriate for men and women. In other words, it refers to how we expect men and women to act, dress, speak, etc.

This gender roles usually have a big impact in our lives since we are exposed to them since when we are little kids and they will have an impact in how we speak, dress and even choose a career (for example, there's an stereotype by which "women are not good in exact sciences such as math and physics).

Therefore, gender roles have enormous consequences for the behavior of most people and influence a wide range of human activities, including how we speak, dress, walk, engage in courtship, and choose a career.

vichka [17]

A school atmosphere in which the motions of teaching and learning continue, while the students are more concerned about surviving than learning is called <u>Ritualized Deprivation</u>.

Students go to school to learn new things and to gain knowledge about the world and different topics regarding what is going around the globe. They learn these topics so that they can develop skills and gain knowledge so that they become successful in life. But sometimes the students take learning as just a task and they are not interested in learning. They feel like they are surviving the task of learning instead of enjoying it. This type of learning environment is known as Ritualized deprivation. The atmosphere of learning should be made more fun loving and participative by teachers so that students can enjoy learning.
