Website-Based Electronic Module With SSI on Human Excretory System Material to Improve Cognitive Abilities and Critical Thinking

This development research aims to determine the feasibility, practicality and effectiveness of website-based electronic modules with socio scientific issue (SSI) on human excretory system material to improve cognitive abilities and critical thinking of class XI high school students. This type of research is R&D (research and development) with the ADDIE model (analysis, design, development, implementation and evaluation). The feasibility of the developed product was assessed by material and media experts, practicality was assessed by biology teachers and student responses. Effectiveness is obtained from the results of field trials by implementing the product to experimental class students and not implemented to control class students. Analysis of product feasibility and practicality was calculated using the feasibility and practicality test formula, while the analysis of the results of cognitive abilities and critical thinking was calculated using Exel and SPSS 23. The results showed that the web-based electronic module product with SSI on human excretory system material developed was very feasible to use with very good criteria, based on the feasibility test. The product is also very practical to use with very good criteria according to biology teachers and students. The developed product is known to be effective in improving students' cognitive and critical thinking skills. The average result of cognitive ability in the experimental class of 73.44 is greater than the control which is 64.78. The average result of cognitive ability in the experimental class was 72.50 with an N-Gain value of 0.64, indicating that the increase was in the moderate category, while the average critical thinking in the experimental class was 0.60 greater than the control class of 41.28. The average result of critical thinking ability in the experimental class is 0.60 which shows that there is an increase in the moderate category. Based on these results, it is known that the cognitive and critical thinking abilities of students obtained a sig value. (2-tailed) 0.05, which means that there is a significant difference in cognitive abilities and critical thinking of students between the control class and the experimental class.
