Development of Website-Based Biology UKBM Module with Discovery Learning Model on Student Learning Outcomes at MAN 1 Medan

This study aims to determine the development of the website-based UKBM Biology module with the discovery learning model at MAN 1 Medan in improving student learning outcomes. The type of research used in this research is the 4D research model developed by S. Thiagarajan, Dorothy S. Semmel, and Melvyn I. Semmel in 1974. This research was conducted from March to May 2023. Based on the expert validation process it shows that this module very valid with a score of 88% material experts, 84% learning design experts, 86% website design experts, 87% biology teachers. Independent t test was conducted to see whether there were differences in the results of the students^ post-tests from the experimental group and the students post-tests from the control group. Based on the data analysis results, it is known that the value of Sig. (2-tailed) is 0.000 <0.05, so it can be concluded that there is an average difference in student learning outcomes between the experimental class and the control class. So it is known that the NGain value for the experimental class is 77.27 which means that the UKBM Biology module uses a website with an effective discovery learning model to apply in biology learning in class X MAN 1 Medan.
