Pengembangan Bahan Ajar Kalkulus Peubah Banyak Berbantuan Software Geogebra Bagi Mahasiswa Pendidikan Matematika

Variable calculus is a subject that requires students to have high mastery and competence. This is because the material presented requires students to think critically and creatively to solve problems. In fact the results of the previous semester's assessment analysis, the percentage of students who graduated with grades A or B was very low. The research method is research and development, with ADDIE development stages, namely Analysis, Design, Development, Implementation, and Evaluation. The results of the needs analysis showed that students need teaching material for calculus variable which is assisted by a technology of mathematical applications, where students' opinions on the need for a mathematical application such as geogebra software in learning, there are 66.7% of students strongly agree, and there are 33.3% agree . The validation results show that the average of all aspects of the assessment of teaching materials obtained an average of 4.29 means that the teaching materials are valid.
