Abstract

This study aims to determine the effect of the STEM learning model on students' numeracy literacy skills. The STEM (Science, Technology, Engineering, and Mathematics) learning model is an interdisciplinary instructional approach that integrates concepts and practices from science, technology, engineering, and mathematics to solve real-world problems. This model emphasizes inquiry-based learning, critical thinking, and problem-solving skills, encouraging students to apply knowledge across disciplines in a cohesive and meaningful way. STEM education aims to enhance students’ cognitive engagement and prepare them for future academic and career challenges in a rapidly advancing technological world. The study was conducted at SMP Darussalam with a sample size of 27 students. A quantitative approach was employed, utilizing data analysis techniques such as normality and homogeneity tests. Subsequently, a t-test was conducted to assess the influence of the STEM model in mathematics learning. The results of the study indicate a significant effect on students' numeracy literacy skills, as evidenced by the average test scores, which increased from 18,852 on the pretest to 30,704 on the posttest. This finding suggests that the null hypothesis (H₀) is rejected and the alternative hypothesis (Hₐ) is accepted.

Abstract

The low level of spatial literacy among elementary school students in geometry is one of the main challenges in mathematics education. This issue is largely due to the lack of interactive learning media and the limited use of instructional methods that support spatial understanding. This study aims to develop a multimedia-based interactive e-book on plane geometry to ence the spatial literacy of fifth-grade students. The research employed a Research and Development (R&D) approach using the ADDIE model (Analysis, Design, Debelopment, Implementation, Evaluation). The participants were 32 Fifth-grade students from SDN Kebon Jeruk 08, West Jakarta. Resesrch instruments included observaitions, interviews, expert validation questionnaires, and pre-test and post-test assessment. The validation results indicated that the interactive e-book is feasible for use, with a feasibility score of 94%. The effectiveness test showed a significant improvement in students’ spatial literacy, with a t-test revealing a mean difference of 26.48 points (p<0.001) between the pre-test and post-test scores. Students became more active, motivated, and cable of communicating spatial ideas more effectively. Therefore, the interactive e-book has proven to be an effective innovarive learning medium for improving elementary students’ spatial literacy. This study recommends the integration of e-books into geometry instruction and teacher training programs to optimize the use of digital media in the classroom.
