Development of Academic Achievement in Biology, on the Topic of Biodiversity, Senior High School, Using the (5Es) Inquiry-Based

Abstract

This research aimed to compare the learning achievement before and after studying biodiversity among Grade 12 students using the (5Es) inquiry-based learning process integrated with multimedia learning materials. The study also examined student satisfaction with this integrated learning approach. The sample consisted of 31 Grade 12 students studying in the second semester of the 2024 academic year at Wachiraprakarn Wittayakhom School, Kamphaeng Phet Province.                 The research instruments included eight lesson plans utilizing the (5Es) inquiry-based learning process integrated with multimedia resources on biodiversity, a 45-item multiple-choice achievement test (with five options per item, totaling 45 points), and a satisfaction assessment form for Grade 12 students regarding the integrated learning approach. Data were analyzed using mean, standard deviation, and dependent t-test statistics. The research findings revealed that: The learning achievement in biodiversity of Grade 12 students using the (5Es) inquiry-based learning process integrated with multimedia learning materials, after studying it increased from 25% to 75%, which was significantly higher after instruction than before at the .05 statistical significance level. The overall satisfaction of Grade 12 students after learning through the (5Es) inquiry-based learning process integrated with multimedia learning materials was at a high level.
