Abstract

The aim of the research was to develop a collaborative online learning design for integral calculus courses through lesson study activities. The study employed didactical design research as the research design. Participants in the research consisted of 19 students (aged 19–22 years, 18 women) from two private universities in Indonesia. The researcher served as the main instrument in the study, utilizing several additional instruments, such as collaborative online learning design, presentation slides, and documentation studies. The data were analyzed using qualitative data analysis. The research revealed that collaborative online learning design through lesson study activities helped prospective mathematics teachers understand concepts related to integral calculus, especially definite integrals and the substitution method. This was because the collaborative online learning design used learning videos as a means for students to understand the concept of integral calculus. Apart from that, the collaborative online learning design also facilitated students’ understanding of this concept more deeply.

Abstract

The purpose of this research was to design a high school vector learning module within the Independent Curriculum based on Problem-Based Learning (PBL) integrating numeracy skills with valid and practical criteria. This research was R&D (Research and Development), and the research model used was ADDIE (analysis, design, development, implementation, and evaluation). Data collection used validation instruments and questionnaires. The module was validated by five expert validators, and its practicality was piloted by two teachers and 15 students. Based on the research results, the PBL-based learning module design integrating numeracy skills was declared highly valid with an average validity percentage of 76% and met the criteria for highly practical with an average practicality percentage of 89%. The research concluded that the PBL-based learning module design met the criteria for highly valid and practical, making it suitable for use in the 10th-grade high school mathematics learning process for vectors.
