Interactive Instructional Material in Teaching Atomic Structure: Development and Validation
This study was conducted to develop and validate an interactive instructional material in teaching atomic structure for Grade 8 learners. The study used research and development cycle (R & D) to come up with an interactive material in science instruction. The interactive instructional material was evaluated by Science and Information Technology experts, respectively. The interactive instructional material was excellent in terms of relevance, adequacy, appropriateness, and instructional characteristics. Likewise, the interactive instructional material was very satisfactory in terms of usability, functionality, and user interface. All indicators showed that the interactive instructional material is highly acceptable. Statistics showed no significant difference between the pretest means scores of the control and experimental groups. Both traditional method and the use of interactive instructional material were effective in improving learners’ performance. However, the use of interactive instructional material was more effective than the traditional method after comparing the mean scores of the posttest of the control and experimental groups (d = 0.05). It is recommended that the interactive instructional material be used as a supplement in teaching atomic structure in Chemistry.
