Abstract

This study aims to determine the effect of LKPD STEM using Problem Based Learning (PBL) model on reaction rate material. This research was conducted at SMAN 8 Medan in the 2022/2023 school year. This type of research is a quasi experiment with pretest posttest control group design. The population in this study were all XI MIPA classes at SMAN 8 Medan. The research sample was XI MIPA 4 class as an experimental class taught with STEM LKPD using Problem Based Learning (PBL) model and XI MIPA 1 class as a control taught using Problem Based Learning (PBL) model without STEM LKPD. The instruments used in this study were 20 multiple choice questions that had been tested for validity, reliability, difficulty level and differentiation, and 25 items of questionnaire statements of learning interest. The results of this study indicate that there is an effect of STEM LKPD using the Problem Based Learning (PBL) model on learning outcomes with hypothesis testing sig. 0,001 < α (0,05). In addition, there is an effect of STEM LKPD using the Problem Based Learning (PBL) model on learning interest with a hypothesis test sig. 0,000 < α (0,05).

Abstract

This study aims to determine the needs analysis, validity, practicality, effectiveness and student response to STEM-PjBL-based E-Modules. This research was conducted at SMAS Kartika I-2 Medan and the sample of class XI IPA 2. The type of research used is Research and Development (R&D) and the development model is 4-D (Four D). The data collection technique is through interviews, observations, questionnaires and tests. Data analysis on the validity test uses the kappa moment formula and the effectiveness test uses the N-Gain test. The results obtained are analyzing the needs of teachers have not maximally used the PjBL learning model, and have never used STEM-PjBL-based E-Modules and the books used have not contained projects and STEM. As many as 69.7% of students feel bored and 57.6% of students prefer to do project-based learning. Validity obtained an average kappa moment of 0.82 very high category, from material experts 0.86 and media experts 0.79 very high category. Practicality by teachers obtained an average kappa moment of 0.99 very high category. Effectiveness obtained an average N-gain of 0.52 medium category. Student response obtained an average kappa moment of 0.81 very high category.
