Simulation-Based Instructional Materials on Central Dogma of Molecular Biology

Abstract

The essence of Genetics lies in the understanding of the concepts of Central Dogma of Molecular Biology. Although these ideas are fundamental to the field, they are notoriously difficult to understand and visualize. While simulation-based instructional materials are found to improve the teaching-learning process in science education, little has been done to assess their effectiveness in teaching and learning the concepts of Central Dogma of Molecular Biology. Hence, this study aimed to examine the effectiveness of simulation-based instructional materials towards the learning performance of Grade 12 learners on the concepts of Central Dogma of Molecular Biology. This study utilized a mixed-method approach. Adapted computer simulations were properly integrated in the developed session plans. Pretest and posttest were conducted, and results showed that the learners demonstrated improvement from approaching proficiency to advanced mastery level on the concepts of Central Dogma of Molecular Biology. Furthermore, it was revealed that the learners’ pretest and posttest mean scores on the concepts differed significantly (p<.05). The result of the semi-structured interview revealed that the learners were engaged in experiential learning using simulation-based instructional materials.
