Abstract

This study aims to determine the validity of guided inquiry-based interactive learning media in improving students' Science Process Skills (SPS). The research used a research and development (R&D) approach with a 4D development model, encompassing the stages of definition, design, development, and dissemination, but limited to the development stage. Data were collected using a validation sheet covering aspects of content/material, systematics, language, graphics, and science process skills. This was conducted by expert validators, namely two lecturers from the Department of Biology Education. Data analysis was conducted using quantitative descriptive analysis techniques using validity formulas and criteria for interpreting product validity scores. The results showed that the overall average validation test result for the interactive learning media obtained a score of 89%, indicating a very valid category. Therefore, the validity of the guided inquiry-based interactive learning media has reached product validity and can be developed into the dissemination stage.

Abstract

This study aims to determine the effectiveness of the influence of the Project-Based Learning learning model on the learning outcomes of 9th-grade science students at Junior High School 5 Tuban. The type of research used is experimental research, and the research design is a one-group pretest-posttest Design. The population in this study was the ninth-grade students of SMP Negeri 5 Tuban as a whole, while the research sample was class IX-E students, totalling 31 students. The data collection techniques through learning outcome instruments include pretest and post-test scores. The data analysis techniques used are N-Gain Test analysis and descriptive analysis. The results showed that students' average score after applying the PjBL model increased by 29.03; in contrast, the results of the N-Gain analysis showed a value of 0.69 with a sufficient category. This study concludes that the effectiveness of the project-based learning (PjBL) model affects the results of students' natural science learning
