Validity and Practicality of Problem-Based Integral Calculus Teaching Materials Assisted with Mathematical Software

Abstract

This study aims to develop Integral Calculus teaching materials to improve students' communication skills and positive character. The teaching materials developed are problem-based with the help of mathematical software. The model used refers to the Plomp model. Data on the validity of teaching materials were collected using expert evaluation questionnaires, practicality data on teaching materials were collected using student response questionnaires given to students for the 2020/2021 academic year and lecturer responses. Data were analyzed by descriptive statistics. The results showed that the teaching materials developed had met the valid and practical criteria. Based on the results of the questionnaire, the validity and practicality of teaching materials need to be optimized again in the content, assessment and answer key sections so that they can develop student creativity, especially in communication skills and positive character.
