Abstract

This study employed Latent Profile Analysis (LPA) to investigate engagement patterns among Indonesian university students (N = 81) in a calculus course integrated with STEM through engineering case studies and digital tools. A cross-sectional design using a multidimensional engagement questionnaire identified three distinct profiles: Highly Engaged Digital Learners (22.20%), Minimally Engaged Learners (3.70%), and Moderately Engaged Learners Requiring Support (74.10%). ANOVA results revealed that Highly Engaged Digital Learners achieved significantly superior calculus performance (mean score = 89.70) compared to other profiles (mean difference = 17.30 points, p < 0.001). MANOVA further indicated that this group demonstrated substantially greater development of character virtues, including perseverance, intellectual honesty, and collaborative ethics (all p < 0.001). The findings confirm that STEM-integrated calculus education, when effectively engaging students, serves a dual pedagogical function, simultaneously advancing technical competencies and ethical reasoning. This highlights its transformative potential in fostering holistically developed professionals, aligning with Sustainable Development Goal 4 (Quality Education). Strategic educational responses should include early engagement profiling and targeted support to maximize these benefits.

Abstract

This Community Service Program (PKM) aims to introduce and train students of SMA Negeri 4 Padang in using GeoGebra as an interactive mathematics learning medium. This activity is motivated by the fact that many students still experience difficulties in understanding abstract mathematical concepts such as functions, graphs, and geometric transformations. Therefore, an appropriate learning medium is needed to help visualize concepts in a more concrete and comprehensible way. The implementation method includes several stages: preparation, opening and team introduction, material presentation by the instructor, guided hands-on practice using laptops, question-and-answer sessions accompanied by rewards to enhance participation, and a closing session with group photos. The results indicate that students were highly enthusiastic throughout the training, actively participated in discussions, and showed increased interest and motivation in learning. The use of GeoGebra effectively helped students visualize mathematical concepts more clearly, interactively, and engagingly. Overall, this activity had a positive impact on improving students’ conceptual understanding and motivation in learning mathematics.
