Designing a constructivist learning aid module in disentangling least mastered competencies in the wave motion

This study sought to design constructivist learning aid module in disentangling least mastered competencies in wave motion among the 72 Grade 7 students of Quezon Science High School, S.Y. 2019-2020. Specifically, it sought to test if there is significant difference between the pre-test and post-test scores. Also, level of acceptability of the developed instructional material was evaluated. A 30-item achievement test (pre-test and post-test) and the questionnaire. One-group pre-test post-test design was used as the research design. The findings showed that the mean scores of the students in the pre-test and post-test is 11.29 and 29.08 respectively. The computed t-value is -13.176 is less than the tabular value of -1.99 at 0.05 level of significance. There is a significant difference between the pre-test and post-test scores after the utilization of the said learning material. It implies that the constructivist learning aid module is a valid tool in disentangling the least mastered competencies in wave motion. The average weighted mean values for the following criteria on the level of acceptability are as follows: learning objectives (3.74); learning activities (3.72); clarity (3.74); accuracy (3.76); appeal (3.67); and usability (3.74). These criteria fall under “strongly agree”. Thus, the developed constructivist learning aid module in disentangling least mastered competencies in wave motion is commendable to use.
