Analysis of the Relationship Between Economic Background and Access to Technology on Motivation to Study Chemistry

2026-07-23T09:07:34+00:00

This study aims to analyze the socioeconomic background and access to technological resources of 10th-grade students at SMA Negeri 5 Padang, as well as their impact on motivation to learn chemistry. Using a descriptive survey approach with a cross-sectional design, data were collected from 36 students via a questionnaire and analyzed using descriptive statistics and Rasch modeling. The results indicate that the majority of students come from lower-middle-income families. There is a paradox: while 100% of students own smartphones, only 25% use them for learning. Although students’ intrinsic motivation was low, their extrinsic motivation regarding the need for digital media was very high, and Rasch analysis revealed that the highest motivation was actually found among students from low-income families with independent access to smartphones. Therefore, this study recommends the development of interactive, mobile-friendly, and data-efficient smartphone-based chemistry learning media to bridge the economic gap and enhance students’ learning motivation in an inclusive manner.

The Integration of Smartboard Media within the Direct Instruction Model to Enhance Students’ Learning Outcomes in Reaction Rate Topics

2026-07-28T08:15:26+00:00

The integration of technology in chemistry learning is increasingly essential to overcome the abstractness of chemical concepts. This study aims to examine the effect of smartboard media integration within the Direct Instruction model on students' learning outcomes in reaction rate material. A pre-experimental approach with a One Group Pretest-Posttest Design was used, involving 43 students of class X.E at SMK SMAK Makassar selected through purposive sampling. Data were collected through pretest and posttest instruments, then analyzed using the Wilcoxon Signed Rank Test, N-Gain, and Cohen's d effect size. The results showed an increase in the average score from 49.30 in the pretest to 61.16 in the posttest. The Wilcoxon Signed Rank Test confirmed a significant difference (Asymp. Sig. = 0.000 < 0.05). Although the N-Gain value of 0.21 fell in the low category partly attributed to the ceiling effect for high-pretest students and the inherent conceptual complexity of reaction rate the Cohen's d value of 0.73 indicated a medium practical effect, comparable to other innovative chemistry teaching strategies. The synergy between smartboard's dynamic visualizations and the structured, step-by-step delivery of Direct Instruction effectively facilitated students' understanding of abstract submicroscopic concepts such as collision theory and activation energy. These findings suggest that smartboard-integrated Direct Instruction is a pedagogically promising approach for chemistry classrooms equipped with interactive technology, while differentiated feedback strategies are recommended to further optimize individual learning gains.
