Abstract

The study aims to determine the effectiveness of the STEAM-based Project-Based Learning (PjBL) model in improving critical thinking skills among elementary school students. This research is based on the issue of low critical thinking ability in Science subjects, particularly because the STEAM approach has not yet been applied in learning. The study was conducted at 1 Pawenang Elementary School as an effort to introduce a learning model that integrates Science, Technology, Engineering, Art, and Mathematics. The STEAM-based PjBL syntax includes formulating essential questions, designing project plans, preparing information-gathering schedules, implementing projects, monitoring activities, testing project outcomes, evaluating learning experiences, and drawing conclusions. This study used a mixed-methods approach with a sequential explanatory design. The quantitative phase examined the effectiveness of STEAM in improving students’ critical thinking in Science, while the qualitative phase, through interviews and observations, identified the processes and supporting factors influencing the model’s implementation. The results showed that the STEAM-based PjBL model was effective in enhancing students’ critical thinking skills. Statistical analysis indicated a significance value of 0.001 < 0.05, meaning that the STEAM-based PjBL model had a significant positive effect on the improvement of students’ critical thinking character.

Abstract

General Background: The digital era requires elementary school students to possess critical thinking as a foundational character to evaluate information and make reasoned decisions within learning processes. Specific Background: Project-based learning integrated with STEAM has been positioned as a relevant pedagogical context for fostering critical thinking, yet systematic assessment remains challenging at the elementary level. Knowledge Gap: Existing assessment instruments are predominantly conventional and lack robust psychometric validation to comprehensively measure critical thinking characteristics in STEAM-oriented project learning. Aims: This study aims to validate a critical thinking character assessment instrument for elementary school students using Rasch Model analysis within project-based STEAM learning in the digital era. Results: From 29 developed items, 20 items met Rasch validity criteria, with person reliability of 0.82, item reliability of 0.98, and a Cronbach’s Alpha value of 0.81, indicating strong internal consistency and effective differentiation of student ability levels. Novelty: This study presents a psychometrically validated instrument specifically designed to assess critical thinking character in elementary school students through STEAM-based project learning using Rasch Model analysis. Implications: The validated instrument provides teachers with an objective and systematic assessment tool to monitor and develop students’ critical thinking character in alignment with the demands of digital-era elementary education. Highlights • The instrument demonstrated high person and item reliability through Rasch analysis• Valid items represented five dimensions of critical thinking character• Assessment results supported objective differentiation of student ability levels Keywords Critical Thinking; Rasch Model; Project Based Learning; STEAM Education; Elementary School
