Abstract

This study aimed to design a Student Worksheet (LKPD) to improve students' critical thinking skills on the topic of Aves. The method used was Research and Development (R&D) with the 3D model, consisting of the define, design, and develop stages. The research subjects were students of Class X4 at a school in Bandung Regency, West Java. Data were obtained through validation sheets from a subject-matter expert, a pedagogical expert, and a biology teacher, as well as pretest-posttest questions based on critical thinking indicators. Data were analyzed using the Likert-scale feasibility percentage and the N-Gain test. The results showed that the developed LKPD was categorized as feasible to highly feasible according to the three validators, and was shown to improve students' critical thinking skills at a moderate level. Therefore, the developed LKPD is suitable for use in instruction and effective in improving students' critical thinking skills on the topic of Aves. Keywords: Aves, Biology Education, Critical Thinking Skills, LKPD, Research and Development

Abstract

This study aimed to analyze the improvement of students' creative thinking skills through the implementation of project-based learning integrated with the Environmental-STREAM approach in the topic of plant structure and tissues by utilizing the local potential of mendong fiber (Fimbristylis globulosa). The research was conducted at a public senior high school in Tasikmalaya Regency in April 2026. A quasi-experimental approach with a Static Group Pretest-Posttest Design was employed. The sample was selected using a purposive sampling technique, resulting in an experimental group consisting of 38 students who participated in Project-Based Learning (PjBL) integrated with Environmental-STREAM and a control group consisting of 40 students who participated in conventional PjBL. Data were collected using a creative thinking skills test instrument covering the indicators of fluency, flexibility, originality, and elaboration. The data were analyzed using the N-Gain test based on established classification criteria. The results indicated that the experimental group achieved an average N-Gain score of 0.72, which was categorized as high, while the control group obtained an N-Gain score of 0.69, categorized as moderate. Indicator-based analysis revealed that fluency achieved the highest score of 0.76, whereas originality showed the lowest score of 0.68. Based on these findings, it can be concluded that project-based learning integrated with the Environmental-STREAM approach through mendong fiber craft-making activities was effective in enhancing students' creative thinking skills compared with conventional learning.
