If a researcher wants to do a study to show that active learning strategies help students learn she should
A)manipulate teaching strategies by having one group assigned to work with active learning strategies and a second group assigned to work with strategies that did not involve active learning and see if students' performance covaries with the teaching method.
B)have one teacher teach one group of students with active learning strategies and have a different teacher teach a second group of students with a method that did not use active learning strategies,then compare the performance of the two groups.
C)have students choose to learn either using active learning strategies or using methods that did not use active learning strategies and then compare the performance of the two groups of students.
D)teach one group of students with the active learning strategies and describe the students' performance based on her observations.

Question

Quizplus · Accepted Answer

By manipulating teaching strategies and comparing the performance of two groups, the researcher can establish a cause-and-effect relationship between active learning strategies and student learning. This type of experimental design is the most appropriate for testing the effectiveness of a teaching intervention. Option B does not control for potential teacher differences that could affect the results, while option C does not assign the groups randomly, which could bias the results. Option D lacks a comparison group and does not provide a basis for comparison.
