Construct 2 learning media developments to improve understanding skills

The objectives of this research were to find out how to develop, to know the feasibility, and to find out the teacher’s and students’ responses toward Construct 2 as the mathematics learning media on polyhedron material. The use of instructional media can make data presentation more attractive and reliable, facilitate data interpretation, summarize information, and increase students’ understanding. This research employed the Research and Development method or R&D with ADDIE as the development model (Analysis, Design, Development, Implementation, and Evaluation). The data collection techniques employed were questionnaires and documentation. The questionnaires were distributed to four kinds of respondents, namely the media expert, the material expert, the student, and the teacher. The result of validation by media expert was in the high category. The results of the validation by the material expert and the media expert stated that the Construct 2 learning media was suitable to be used in teaching and learning activities for the seventh-grade students on polyhedron material. The application of Construct 2 was categorized as excellent based on the results of the small-group trial and large-group trial. Furthermore, the teacher’s responses during the trials indicated that the Construct 2 learning media was categorized in the excellent category.
