Pengembangan e-modul mata kuliah kalkulus berbasis blended learning untuk mahasiswa Jurusan Tadris Matematika IAIN Kerinci menjadi fokus penelitian ini. Penelitian ini dilakukan karena terdapatnya hambatan didaktis khususnya untuk bahan ajar sebesar 64% yang menjadikan mahasiswa kesulitan untuk belajar. Pengembangan e-modul berbasis blended learning bertujuan menghasilkan e-modul yang dapat dikategorikan valid dan praktis agar dapat digunakan oleh mahasiswa. ADDIE merupakan desain dari penelitian dan pengembangan yang dilakukan. 30 orang menjadi subjek penelitian yang berasal dari mahasiswa jurusan tadris matematika IAIN Kerinci yang sudah dan sedang mengontrak mata kuliah kalkulus. Data diperoleh melalui teknik pemberian angket validitas dan angket praktikalitas lalu data dianalisis dengan cara deskriptif kualitatif untuk mendeskripsikan saran para ahli serta analisis kuantitatif untuk mengolah data hasil angket. Hasil penelitian menunjukkan bahwa e-modul berbasis blended learning pada mata kuliah kalkulus valid dan praktis.
The focus of this research is the development of a blended learning-based calculus course e-module for students of the Mathematics Tadris Department at IAIN Kerinci. This research was carried out because there were didactic barriers, especially for teaching materials of 64%, which made it difficult for students to learn. The development of e-modules based on blended learning aims to produce e-modules that can be categorized as valid and practical so that students can use them. ADDIE is the design of the research and development carried out. 30 people who became the research subjects came from students majoring in mathematics at IAIN Kerinci who had and were currently contracting calculus courses. The data were obtained by administering validity and practicality questionnaires. Then, the data were analyzed using a qualitative descriptive method to describe the advice of experts and quantitative analysis to process the results of the questionnaire data. The results of this study obtained e-modules based on blended learning in valid and practical calculus courses.
