Question

As a secondary mathematics teacher, Hernandez conducted a study that explored whether giving children recess prior to testing helped their test performance. For one of the semesters, he sends half of his classes out for 10 minutes of recess prior to testing for the other half, he provides 10 minutes of free time after the test. Which of the following best represents the design of Hernandez’s study? 1. Static-group comparison 2. Post-test only control group 3. Solomon four group 4. One-shot case study

Explanation / Answer

There is no pre-test score here in this study. So from the given study it can be looked from either in static group comparison or post test only control group. As one group receives the treatment and the other doesn't. But the only difference of static group comparison and post test only control group is the randomization. here, whether the students in the control groups are selected randomly or not is not explained. If the choice of half of the students is done randomly then it is a Post test only control group design otherwise it will be a Static group comparison.
