Abstract

This study aims to develop TPACK-based digital economics worksheets and to examine their validity, practicality, and effectiveness in enhancing students’ critical thinking skills. The research employed a Research and Development (R&D) method using the ADDIE model, which consists of the analysis, design, development, implementation, and evaluation stages. The participants were tenth-grade students at SMK Negeri 1 Angkola Timur, North Sumatra. The research instruments included expert validation sheets, teacher and student response questionnaires, critical thinking skill tests, and learning achievement tests. Data were analyzed using descriptive quantitative and qualitative methods, normality testing, N-Gain analysis, and effectiveness testing. The findings revealed that the developed digital worksheets were highly valid based on evaluations by content, media, and instructional design experts. The practicality analysis indicated that the worksheets were highly practical, as reflected in positive responses from both teachers and students. Furthermore, the implementation of the TPACK-based digital worksheets was proven to be effective in improving students’ critical thinking skills, as demonstrated by increased mean scores and moderate to high N-Gain values. Therefore, TPACK-based digital economics worksheets are suitable for use as innovative instructional materials in vocational high school economics learning.

Abstract

This study examined whether implementation of the Discovery Learning instructional model was associated with improved economics learning outcomes on entrepreneurial characteristics among tenth-grade social science students at Madrasah Aliyah Nahdlatul Ulama Batangtoru. A pre-experimental one-group pretest-posttest design was employed with a sample of 35 students (total population). The intervention consisted of four 90-minute sessions over two weeks, applying the six-stage Discovery Learning framework (stimulation, problem statement, data collection, data processing, verification, and generalization). Data were collected through observations, a validated 25-item multiple-choice test, and documentation. Because pretest and posttest scores were not normally distributed (Shapiro-Wilk p = 0.039 and p < 0.001, respectively), the Wilcoxon signed-rank test was applied. Results showed Z = -5.175 and Asymp. Sig. (2-tailed) = 0.001. Since p < 0.05, the null hypothesis was rejected. Posttest scores (M = 93.71, SD = 5.47) were significantly higher than pretest scores (M = 49.43, SD = 13.44), with 33 of 35 students (94.3%) meeting the Minimum Completion Criteria compared to only 15 students (42.86%) at pretest. While these findings suggest that Discovery Learning was associated with improved learning outcomes, causal attribution remains limited by the absence of a control group and other threats to internal validity inherent in the one-group pre-experimental design.
