Effectiveness of STEM-Based E-Worksheets Through Project-Based Learning on Strategy and Tactics Indicator

The ability to formulate strategies and tactics, one of the critical thinking indicators, remains relatively low in physics education. Meanwhile, previous studies on STEM-based electronic student worksheets (E-LKPD) integrated with Project-Based Learning (PjBL) have generally assessed critical thinking as a whole rather than focusing on specific indicators. This study aimed to examine the effectiveness of STEM-based E-LKPD implemented through the PjBL model in improving students’ Strategy and Tactics ability on the topic of work and energy. A quantitative approach with a quasi-experimental nonequivalent control group design was employed. The participants consisted of 30 students in the experimental class and 32 students in the control class. Data were collected using an essay test measuring the Strategy and Tactics indicator and analyzed using the Shapiro–Wilk test and the Wilcoxon signed-rank Test. The findings revealed that students’ strategy and tactics ability improved in both classes, with a greater improvement in the experimental class. The Wilcoxon signed-rank Test indicated a significant difference between pretest and posttest scores in the experimental class (p < 0.05). These findings suggest that STEM-based E-LKPD through the PjBL model effectively enhances students’ Strategy and Tactics ability in physics learning.
