Abstract

Science learning media play an important role in the learning process because science is closely related to everyday life and helps students understand themselves and their environment. This study aims to examine the effect of the Project-Based Learning (PjBL) model assisted by miniature media on students’ learning outcomes and creative thinking skills in the solar system topic at SMP Negeri 17 Medan. This research used a quasi-experimental method with a pretest-posttest control group design for learning outcomes and a one-posttest control group design for creative thinking. The sampling technique applied was cluster random sampling, where each class was treated as a cluster. Two classes were randomly selected as samples: class VII-2 as the control group receiving conventional instruction, and class VII-3 as the experimental group taught using the PjBL model assisted by miniature media. The research instruments consisted of a multiple-choice learning achievement test and a creative thinking observation sheet based on Torrance’s indicators of fluency, flexibility, originality, and elaboration. The instruments were validated by experts and pilot-tested to ensure validity and reliability. Data were analyzed using a one-tailed t-test with SPSS version 30. The results indicated that students taught using the PjBL model with miniature media achieved higher learning outcomes and creative thinking skills than those taught conventionally. The t-test results showed significance values of 0.001 < 0.05 for both learning outcomes and creative thinking. Therefore, the PjBL model, assisted by miniature media, positively and significantly influences students’ learning outcomes and creative thinking skills on the solar system topic at SMP Negeri 17 Medan.

Abstract

The purpose of this study is to analyze the need for improvement of chemistry teaching materials for high school grade XI on reaction rate material, and the findings of this study will be consulted for further information in the development of electronic chemistry teaching materials or e-modules that are integrated with project-based learning-based ethnopedagogy. A qualitative descriptive method was employed in this study. The research was conducted at SMAN 2 Percut Sei Tuan through interviews with a chemistry teacher and classroom observations in class XI-C, involving 36 students. The results indicate that the teacher has never used e-modules in chemistry learning, particularly for reaction rate materials. Learning activities are still limited due to the lack of laboratory tools and materials, resulting in the use of simple teaching resources that are not integrated with local wisdom. The teacher also acknowledged that the development of ethnopedagogy-based e-modules integrating local wisdom is highly necessary to provide authentic learning experiences, enabling students to better understand abstract reaction rate concepts and construct their own understanding independently. Furthermore, the results of the student needs analysis questionnaire show that 85.5% of students are interested in and agree with the development of project-based e-modules integrated with ethnopedagogy, as this approach supports independent exploration of their understanding.
