THE EFFECTS OF USING INTERACTIVE E-LEARNING LESSONS INTEGRATED WITH PROJECT-BASED LEARNING TO DEVELOP CODING ABILITIES OF GRADE 7 STUDENTS

Abstract

The objectives of this research were 1) to develop and determine the efficiency of interactive e-learning lessons based on the 80/80 criteria and 2) to compare the programming knowledge of Grade 7 students before and after learning through interactive e-learning lessons combined with project-based learning. This study employed a pre-experimental design, specifically the One-Group Pretest–Posttest Design. The sample consisted of 35 Grade 7 students from Samutsakhon wittayalai School. The research instruments included interactive e-learning lessons, a pre-test, a post-test, programming ability exercises, and project evaluation forms. Data were analyzed using percentage, mean, standard deviation, and t-test for dependent samples, along with the E1/E2 efficiency evaluation.

The research results revealed that the developed interactive e-learning lessons achieved an efficiency of 80.20/80.29, which exceeded the specified criteria, with an average process score (E1) of 80.20 percent and an average product score (E2) of 80.29 percent, demonstrating the quality of the lessons. Furthermore, the students' learning achievement after the lessons was significantly higher than before the lessons at the .05 level, with a pre-test mean score of 10.20 and a post-test mean score of 15.91. These findings indicate that the students’ programming knowledge and abilities clearly increased following the implementation of the developed lessons.
