Posttest
The two groups were given the same pretest questions, one day later to compare and measure the achievement of both groups.The two tests were designed to estimate the number of relevant concepts that students can recall at the end of the lecture (i.e. questions were related to lecture objectives). The students were expected to form links of concepts correlated to the different learning items and relate the new concepts to their prior knowledge. Any differences that appear in the test results should be the result of the experimental variable for student performance assessment.
