Abstract

A common problem in learning is the low achievement of students, which is influenced by differences in students’ understanding and learning styles, as well as the insufficient application of innovative and student-centered learning models. Therefore, an instructional approach that can address these issues is needed, such as differentiated learning combined with the Problem Based Learning (PBL) model. This study employed a quantitative approach using an experimental method with a One-Group Pretest-Posttest Design. The research subjects were tenth-grade students of the Electrical Installation Engineering program at SMK N 2 Sawahlunto. Data collection was conducted using pretest and posttest instruments to assess students’ learning outcomes. The data obtained were analyzed using N-Gain scores and classical completeness. The results indicate that the implementation of differentiated learning integrated with the PBL model is quite effective in improving students’ learning outcomes. This is evidenced by an increase in the average posttest score to 86.06 from a pretest score of 59.66. The implementation of differentiated learning was proven to significantly enhance students’ learning achievement, as reflected by a normalized gain score of 0.66, which falls into the medium category, with a classical completeness of 97%.

Abstract

This study investigates the effectiveness of implementing the Guided Discovery Learning model in improving student learning achievements within the Fundamentals of Electrical Power course for tenth-grade learners specializing in Electrical Power Installation at a vocational high school in Padang, Indonesia. The research adopts a quantitative methodology featuring a one-group pretest-posttest design, where participants engaged with a validated multiple-choice assessment tool confirmed reliable via product-moment correlation and internal consistency checks. Descriptive statistics, normalized gain calculations, the Wilcoxon signed-rank test, and effect size analysis were applied to evaluate improvements. Findings reveal a marked enhancement in post-intervention scores compared to initial assessments, with normalized gains predominantly falling into moderate categories, alongside a subset achieving higher levels and a smaller portion showing lower progress. The Wilcoxon test indicates statistically significant differences between pre- and post-scores, while the effect size points to a substantial influence. These results affirm that Guided Discovery Learning effectively bolsters conceptual understanding of electrical principles, fosters active engagement, reduces learning disparities among vocational students, and promotes a more equitable classroom dynamic. Consequently, this student-centered approach is recommended as a viable alternative to traditional teacher-led methods in vocational settings, particularly for technical subjects like electrical fundamentals, to better align education with industry demands and enhance practical problem-solving skills.
