Abstract

This article aims to describe philosophically related to Constructivism-Based Science Practicum. This article uses a qualitative descriptive approach. Information was obtained based on observations, experience, and a literature review from several journal literature. Philosophical studies can strengthen ontology related to the nature of constructivism-based science practicum, a science practicum that leads to constructing students' thinking so that knowledge, skills, and attitudes are increasing. Epistemologically (usefulness), constructivism-based science practicum can improve students' concepts and skills in understanding science concepts. Axiologically (Universal values) constructivism-based science practicum can be obtained from science practicum activities that shape scientific attitudes and behaviour in general.

Abstract

Mathematics education in Indonesia still faces challenges in developing students' Higher Order Thinking Skills (HOTS), particularly in mathematical problem-solving ability. One of the reasons for this is the limited availability of instructional materials specifically designed to support PBL-STEM. This study aims to develop Problem-Based Learning (PBL)-based mathematics instructional materials integrated with STEM to enhance the problem-solving abilities of science-stream students. This study is a Research and Development (R&D) project using the 4D model (Define, Design, Develop, and Disseminate). The subjects of this study consisted of 30 students from Grade 11 of SMAN 1 Labuhan Haji, who had low mathematical problem-solving skills. The developed materials included the Lesson Plan (RPP), Student Worksheet (LKS), problem-solving test, and practicality questionnaire for teachers. The results of validation by experts showed that the developed materials received an average score of 94.9%, which falls into the “highly valid” category. The practicality questionnaire, filled out by teachers, resulted in an average score of 92.5%, indicating that the materials are easy to use and well-structured. The effectiveness test, measured through a problem-solving test, showed an average N-Gain score of 0.72, which falls into the “high” category, indicating that the materials significantly improved students' problem-solving abilities. In conclusion, the PBL-STEM instructional materials developed in this study are valid, practical, and effective in enhancing the mathematical problem-solving ability of science-stream students.
