Abstract:
The aim of this study is to develop teaching material products in the form of open problem-based e-modules in geometry learning courses. Plomp’s development stages are used in this study, namely preliminary research, prototype stage, and assessment stage. This paper focuses on the assessment stage, the e-module field test. The field test is conducted at the Elementary School Teacher Education Study Program of PGRI Kanjuruhan University Malang, Nusantara PGRI University Kediri, and STKIP PGRI Trenggalek involving 277 students as subjects. In the field test, the practicality and effectiveness of the E-Module were measured using the Lecturer and Student Response Questionnaire and the Creative Thinking Ability Test. Based on the analysis results, lecturers and students responded positively to the designed e-module. More than 75% of the students' creative thinking ability level was at least in the “High” category. The form of open problems presented in this e-module makes students able to provide more than one solution and were also able to provide alternative solutions to open problems. However, in general, students are still unable to come up with new and unique solutions. The results of this study show that e-module meet the criteria of practicality and effectiveness.
