Development of Guided Discovery Learning Oriented E-LKPD
Critical thinking skills from student learning outcomes are one of the emphases in 21st century learning. Critical thinking skills can train students to be good at selecting the information needed in solving problems, more skilled at detecting conceptual deviations, so as to be able to correct these deviations and can solve problems logically, systematically, rationally, and empirically. One of the learning models that can improve critical thinking skills which will affect learning outcomes is the guided discovery learning model. The guided discovery learning model can be integrated into learning media in the form of e-LKPD oriented towards guided discovery learning on cell material. Cell matter is a material that is quite broad and complex. This research is a type of research and development (R & D) research. This study uses a 4D development model (define, design, development, disseminate). This study aims to produce guided discovery learning-oriented e-LKPD and describe the validity, practicality and effectiveness of improving critical thinking skills and student learning outcomes on cell material. This guided discovery learning-oriented electronic student worksheet (e-LKPD) has been implemented in class XI Science 5, 6 and 7 SMA Negeri 3 Klaten for the 2021/2022 academic year. The results showed the validity of the e-LKPD was very valid with a percentage of 90% by material experts and 87.96% by media experts. The results of the practicality of the e-LKPD obtained a percentage of 92.39% very practical criteria from teacher responses and 77.12% practical criteria from student responses. The improvement of critical thinking skills after using the guided discovery learning oriented e-LKPD obtained the percentage results of 80.70% of high criteria and the percentage of students' critical thinking skills questionnaire percentage of 75.85% in the high category. Increasing student learning outcomes after using guided discovery learning-oriented e-LKPD obtained the results of the classical completeness percentage of 88.88% having reached KKM = 70 and obtaining g ≥ 0.3 of 86.11% in the medium to high category. Thus, it can be concluded that the guided discovery learning-oriented e-LKPD developed is valid, practical and effective to use in learning.
