Abstract

Kemampuan Berpikir Tingkat Tinggi (HOTS) siswa dalam pembelajaran matematika masih rendah, khususnya pada kemampuan menganalisis, mengevaluasi, dan mencipta. Penelitian ini bertujuan menguji pengaruh Problem-Based Learning yang diperkaya dengan scaffolding metakognitif (PBL-MS) terhadap peningkatan HOTS siswa. Penelitian kuasi-eksperimental dengan desain pretest–posttest control group melibatkan 60 siswa kelas X SMA Negeri 15 Bandung yang dibagi ke dalam kelompok eksperimen (PBL-MS) dan kontrol (PBL). Data kemampuan HOTS dikumpulkan melalui tes tertulis berbentuk esai berdasarkan taksonomi Bloom revisi. Hasil penelitian menunjukkan bahwa peningkatan HOTS siswa pada kelompok PBL-MS berada pada kategori sedang (N-Gain = 0,51), sedangkan kelompok PBL berada pada kategori rendah (N-Gain = 0,30), dengan perbedaan yang signifikan (Sig. 2-tailed < 0,05). Temuan ini menunjukkan bahwa integrasi scaffolding metakognitif dalam PBL lebih efektif dalam meningkatkan kemampuan HOTS siswa. Students’ Higher-Order Thinking Skills (HOTS) in mathematics learning remain low, particularly in analyzing, evaluating, and creating skills, indicating the need for instructional strategies that can better support students’ thinking processes. This study aimed to examine the effect of Problem-Based Learning enriched with metacognitive scaffolding (PBL-MS) on improving students’ HOTS. A quasi-experimental study with a pretest–posttest control group design was conducted at SMA Negeri 15 Bandung, involving 60 tenth-grade students divided into an experimental group (PBL-MS) and a control group (PBL). HOTS data were collected using an essay-based written test developed based on the revised Bloom’s taxonomy, covering analyzing, evaluating, and creating indicators. The results showed that the improvement in HOTS of students taught using PBL-MS was in the moderate category (N-Gain = 0.51), while students taught using PBL alone achieved a low category (N-Gain = 0.30). Statistical analysis indicated a significant difference between the two groups (Sig. 2-tailed < 0.05). These findings indicate that integrating metacognitive scaffolding into Problem-Based Learning provides a stronger effect on improving students’ higher-order thinking skills.

Abstract

Occupational Health, Safety, Environment, and Industrial Work Culture learning in vocational schools is often constrained by limited interactive teaching materials, resulting in low student engagement and suboptimal learning outcomes. This condition highlights the urgent need for innovative digital learning resources that align with industrial demands and vocational student characteristics. This study aimed to design, develop, and evaluate the effectiveness of a K3LH E-Module for vocational education students. The research employed a Research and Development approach using the 4D development model, consisting of define, design, develop, and disseminate stages. The research subjects were 60 tenth-grade students of the Automotive Engineering program at Vocational High School in Semarang. Effectiveness testing was conducted at the classroom scale using an experimental group and a control group. Data were collected through expert validation sheets, practicality questionnaires, and pretest–posttest assessments. The results showed that the E-Module was highly feasible, with media expert validation reaching 89.5% and material expert validation 88.9%. Practicality testing indicated a very practical category with a score of 91.3%. Effectiveness analysis using N-Gain yielded a score of 58%, categorised as sufficiently effective. These findings demonstrate that the developed E-Module enhances student learning outcomes and promotes more active participation in K3LH learning. In conclusion, the K3LH E-Module is feasible, practical, and sufficiently effective for use as a digital learning resource in vocational education, with potential for further optimisation to improve learning gains.
