Design of Video Tutorial Media with Explicit Instruction Method to Optimize Informatics Learning in Grade 10

Abstract

The purpose of this study was to design video tutorial media using the Explicit Instruction method to optimize informatics learning in grade 10. Explicit Instruction was selected because it emphasizes systematic, direct, and structured teaching, which is particularly suitable for technical subjects like informatics. This method provides clear guidance, modeling, and step-by-step explanations that help students understand complex procedures more effectively. It ensures that learners are actively guided through each stage of the learning process, making it ideal for developing instructional videos. The primary objective of this study was to develop video tutorial media and measure its contribution to enhancing student comprehension in informatics. This study employed a Research and Development (R&D) approach and tested the optimization using a one-group pretest–posttest design. The development process followed the 4D model. Results from media expert evaluations indicated a feasibility score of 80%. Statistical analysis revealed a significant improvement in students’ understanding of the learning material, as indicated by an increase in test scores from 55.2 (pretest) to 89.0 (posttest). The study concluded that video tutorial media utilizing the Explicit Instruction method can effectively optimize informatics learning, especially for technical materials that require structured teaching.
