Abstract

This research is motivated by the unavailability of determinant matrix teaching materials that meet students' needs and curriculum standards and students' low critical thinking skills, so a determinant matrix teaching module is needed that complies with curriculum standards and facilitates critical thinking skills. Teaching modules are developed using the Project-Based Learning model. This mixed-methods research aims to determine teaching modules' validity, practicality, and effectiveness. This article is a design research report using the Plomp model. The data sources in this research are material expert validators, media experts, educational practitioners, and respondents. The instruments used are validity sheets for material experts, media experts, description tests, observation of the learning process, and critical thinking ability tests. The results of data analysis in this research concluded that the teaching module that had been developed was very valid, practical, and effective. The developed instructional materials are believed to support learning that emphasizes critical thinking. In conclusion, the teaching materials incorporate exercises that enhance critical thinking skills using case presentations. Furthermore, it is suggested that the module be used as an alternative teaching tool and that further research be done with different data, materials, or other mathematical abilities.

Abstract

The purpose of this study was to describe the process and results of the development of the matrix Inverce module related to students' mathematical connection skill, as well as to describe the quality of the matrix Inverce module in terms of validity and practicality. The method used was design research with Plomp model, includes the initial research stage, development stage, and assessment stage. The data was obtained from interview, document analysis, and questionnaire. The result of this study showed that developed module was valid based on validation of material experts, media experts, and practitioner. The validation results of this module show that this module was quite feasible to use with a percentage of 80.83% from material experts and 75.93% from media experts, and was quite practical to use with a percentage of 76.90% from the educator's response questionnaire. From the validation results and educator responses, this module can be implemented as a learning resource or teaching material. In conclusion, the Inverce matrix module was declared fit and practical to be used as teaching material and learning resources.
