Effect of Deep Learning Approach With GeoGebra-Based Interactive PowerPoint and Animated Videos on Concept Understanding

Nur Silvina — 2025-09-23

This study focused on identifying the magnitude of the impact of a deep learning approach assisted by GeoGebra-based interactive PowerPoint media and animated videos on junior high school students’ conceptual understanding, particularly on the topic of straight-line equations. The research employed a quasi-experimental methodology with a pretest–posttest design involving two groups: the experimental group and the comparison group. The measurement instruments consisted of essay questions, and the data were analyzed using normality testing, homogeneity testing, and an independent t-test. The findings revealed a significant improvement in the experimental group’s conceptual understanding. The higher average posttest score compared to the control group confirmed that the use of interactive media enhanced students’ understanding of the material in a more visual and engaging way. Furthermore, the deep learning strategy optimized students’ active involvement in understanding and connecting relevant material to real-life situations. Thus, the synergy between digital media and this learning strategy was proven to effectively enhance conceptual understanding.

Enhancing Students’ Mathematical Literacy Skills through Contextual Teaching and Learning (CTL) and Problem Based Learning (PBL) Approaches

Junianto Junianto — 2025-09-30

The results of the PISA survey conducted by the OECD serve as one of the indicators that the mathematical literacy skills of Indonesian students remain low. Ranking 66th out of 81 countries also indicates that Indonesia is still lagging behind other nations. The purpose of this study is to improve students’ mathematical literacy skills through two alternative learning approaches: Contextual Teaching and Learning (CTL) and Problem-Based Learning (PBL). The research method used was a quasi-experimental design with a pretest-posttest approach to collect data. The population consisted of a junior high school in Yogyakarta, with a sample of two eighth-grade classes. The research instrument was a mathematical literacy test based on PISA-type questions. The findings indicated that the CTL and PBL approaches were both successful in enhancing students’ mathematical literacy skills. Further analysis through a comparative effectiveness test revealed that the CTL approach was superior to PBL. It is hoped that this research can serve as an alternative reference for educators and future researchers in efforts to enhance students’ mathematical literacy.

STEAM in the Perspective of 21st Century Mathematics Learning: A Field Study of Indonesia and Malaysia

Abdul Aziz — 2025-09-30

The aim of this study is to explore the implementation of the STEAM approach in Indonesia and Malaysia in relation to mathematics learning concepts and the skills developed during the mathematics learning process. This study employs a descriptive qualitative method with school students as the research subjects, aiming to examine the application of STEAM in the learning process in both countries. The findings reveal that the integration of STEAM has a positive impact on mathematics learning, particularly in enhancing students’ confidence as well as their critical thinking, creativity, communication, and collaboration skills. The application of STEAM in the context of 21st-century mathematics education encourages students to build self-confidence in facing challenges, which is essential for maximizing their potential.
