Development of Self-discovery and Exploration (SDE) Integrated Low Level Organism Taxonomy Teaching Materials to Improve Students’ Critical Thinking Skills

Abstract

This research aims to improve students' critical thinking skills through the development of self-discovery and exploration (SDE) teaching materials for low-level taxonomy of organisms. This material is a modified version that combines the concepts of Discovery Learning with the mapping of the Indonesian National Qualification Framework. The Indonesian National Qualification Framework consists of six tasks: Routine Tasks, Critical Journal Review, Critical Book Report, Mini-Research, Project and Idea Generation. This research is classified as research and development (R&D) under the ADDIE approach. Data collection techniques through interviews, questionnaires, media test results, and effectiveness tests. Interview sheets, questionnaires, effectiveness tests and media effectiveness tests were used as research instruments. Research data were analyzed by calculating the percentage of the media effectiveness test and the effectiveness of the media in improving students' critical thinking skills. Results showed that there was a significant difference in critical thinking learning outcomes between experimental and control groups classes with tcount of 29.453 on Monera material, 23,204 on Protista material, and 15,214 on Fungi material, while ttable of 1,697 on Sig. (2-Tailed) of 0.000 which indicates tcount > ttable; The acquisition of critical thinking results for experimental class students on each of these materials was 85.40%, 78.41%, 75.88% in the very high category, while control class students were 31.66%, 27.95%, 49.89% in the low category. Thus, it can be concluded that the teaching materials developed are effective in improving students' Critical Thinking Skills.
