The results of the knowledge gained were the same, however the higher achieving classrooms scored higher on the pretest and posttest.

The “manipulate condition” removed the interactive instruction of the teacher and encouraged the students to work in groups to design and run the experiment. They were not given directions on how to build a ramp they were only told they needed to determine how far a ball could roll using a ramp. To make up for the instruction time that was not provided, students worked on more variations of the experiment. In the “both condition” students were lectured in an interactive format as well as in groups to design and run the experiment. After the pretest the interactive instruction provided information on how to conduct the experiment. After the experiments and lectures a posttest was immediately given to determine the student’s level of understanding.

If there were not enough fourth-grade classrooms in a particular school, multiple schools with roughly the same instructional teaching and atmosphere would form a triplet. To ensure the data was not skewed the same two female graduate...
