Abstract
Twenty-first-century learning requires students not only to master concepts, but also to think critically and manage their learning processes independently. One strategy considered promising in addressing these demands is Project-Based Learning (PjBL) integrated with the STEAM approach (Science, Technology, Engineering, Arts, and Mathematics) through authentic tasks, interdisciplinary collaboration, and formative self- and peer-assessment. This study aims to examine the effect of PjBL-STEAM implementation on (1) critical thinking skills and (2) self regulated learning among secondary school students, as well as to explore the relationship between the two by considering potential mediating pathways such as learning motivation/self-regulation. The study employs a quantitative approach with a quasi-experimental Nonequivalent Control Group Design. The sample consists of two classes: an experimental class receiving PjBL-STEAM instruction and a control class receiving conventional instruction, selected purposively based on institutional readiness and teacher capability. Data are collected using a critical thinking test (with a rubric assessing analysis, evaluation, and synthesis of evidence-based arguments) and a self regulated learning scale grounded in self-regulation and metacognition- the instruments are validated through expert review and their reliability is examined through a pilot test. Data analysis is planned using ANCOVA with the pretest as a covariate, as well as path analysis to test mediation if the data and sample size are adequate. The findings are expected to provide empirical support for strengthening curricula and PjBL-STEAM practices to enhance critical thinking and self regulated learning, while considering contextual factors such as teacher readiness, professional development support, and technological infrastructure.
