THE DEVELOPMENT OF SCIENCE, TECHNOLOGY, ENGINEERING, AND MATHEMATICS (STEM)-BASED MATHEMATICS TEACHING MATERIALS TO INCREASE MATHEMATICAL CONNECTION ABILITY
Abstract
Abstract:
This research is development research that aims to develop mathematics teaching materials related to Science, Technology, Engineering, and Mathematics (STEM). This research uses the stages of Research and Development, including problem and data collection, product design, design validation, product test (practicality test), trial test (pretest and posttest), and final product. The results show that teaching materials are valid, practical, and effective to increase mathematical connection ability. The results of the test indicate that teaching materials are valid to use in learning with a percentage of 94.42%. The practicality test results show that teaching materials are easily practised by students, with a percentage of 87.47%. The analysis of the results of the pretest and posttest showed that there was an effective increase in the mathematical connection ability with the n-gain test results of 0.628 on the medium criteria. Thus, mathematics teaching materials in this research can be used in learning, and the copyright was submitted by the electronic intellectual wealth General Directory.
