Abstract

This study aims to evaluate the implementation of advanced calculus courses assisted by GeoGebra using the CIPP model. This evaluation assessed the relevance, effectiveness, and results of applying GeoGebra as an interactive learning medium. The research approach was descriptive quantitative, with data collection through questionnaires and observations. The research subjects were 36 students who attended advanced calculus courses at FMIPA Universitas Negeri Padang in the July–December 2024 semester. The evaluation results show that in the context aspect, the use of GeoGebra is aligned with the curriculum objectives that support the mastery of advanced mathematical concepts and visualization skills. Regarding input, lecturers have basic competence in using GeoGebra, but not all students are familiar with this software. In terms of process, GeoGebra-assisted learning is interactive, although it is constrained by students’ adaptation time to the software. In terms of product, the evaluation results showed increased students’ analytical skills and conceptual understanding, although the increase in exam results was not significant overall. The findings recommend the need for intensive training for lecturers and students related to the use of GeoGebra, the provision of technology-based learning guides, and adjustments to lecture strategies to maximize the effectiveness of GeoGebra in supporting advanced calculus lectures.

Abstract

This study aimed to develop a valid, practical, and effective Problem-Based Learning (PBL) mathematics teaching module integrated with scientific inquiry to enhance mathematical literacy among Grade X vocational high school students in a Computer and Network Engineering program. The development followed the Plomp model, comprising preliminary research, prototyping, and assessment phases. Data were collected through expert validation, student and teacher response questionnaires, observations, and pre- and post-tests. The module was validated by experts with an average score of 3.607 (very valid), while the student worksheets scored 3.582 (very valid). Practicality was confirmed with a 88.33% score from teachers and 88.40% from students, both categorized as very practical. The module significantly improved students’ mathematical literacy, with an average post-test score of 82.66, reflecting gains in formulating, employing, and interpreting mathematical solutions within real-world vocational contexts. Findings indicate that the integration of scientific inquiry into PBL fosters deeper engagement and strengthens problem-solving skills.
