Abstract
This study aimed to develop a website-based interactive e-module on germination and examine its effectiveness in improving biology students conceptual understanding. The development process followed the Hannafin and Peck model, consisting of needs assessment, design, and development stages. The e-module was validated by subject matter and media experts to ensure the feasibility of its content, design, and interactivity. A limited trial was conducted with Biology Education students using a quasi-experimental design with pretest and posttest in experimental and control groups. The experimental group used the developed e-module, while the control group received conventional instruction. Validation results indicated that the e-module was highly feasible in terms of content quality, visual presentation, and technological interactivity. Paired sample t-test analysis showed significant improvement in conceptual understanding in both groups, with greater gains in the experimental group. Independent sample t-test results on posttest scores revealed a significant difference (p < 0.001), indicating the effectiveness of the web-based e-module in supporting learning of abstract biology concepts. Therefore, the developed e-module is feasible and effective for enhancing conceptual understanding and supporting technology-based self-directed learning.
