Abstract

The background of this research stems from the importance of mastering critical thinking skills from an early age in elementary school, especially in facing the rapid development of science and technology. The purpose of this study was to determine the effect of the Scramble learning model on the critical thinking abilities of second-grade students in the IPAS subject at SDN Donggobolo. This research employed a quantitative approach using a quasi-experimental design in the form of a nonequivalent control group design. The research subjects consisted of all second-grade students at SDN Donggobolo, totaling 33 students, comprising 16 students in the experimental class and 17 students in the control class. The instrument used was an essay test designed to measure students’ critical thinking skills. The data analysis technique was carried out through several stages, namely prerequisite tests including normality and homogeneity tests, followed by hypothesis testing using an independent sample t-test. The results of the analysis indicated that the significance value (2-tailed) was 0.001 < 0.05, thus rejecting the null hypothesis (Ho) and accepting the alternative hypothesis (Ha). Therefore, it can be concluded that the use of the Scramble learning model has a significant effect on improving the critical thinking skills of second-grade students. These findings suggest that the implementation of the Scramble learning model can serve as an innovative instructional strategy to enhance the quality of the teaching and learning process, particularly in IPAS learning at the elementary school level.

Abstract

This research addresses the cognitive crisis in primary science education caused by "digital reductionism," which frequently triggers disembodied learning. Excessive reliance on static screen simulations has led to a disconnect between a student’s cognitive processes and physical reality. This study aims to mitigate this gap through a re-materialization strategy, utilizing the frameworks of Material Engagement Theory (MET) and Embodied Cognition. The primary objective is to evaluate the effectiveness of haptic intervention implemented through a Cognitive Interactive Pop-Up Book integrated with an Inquiry Science Approach (ISA). A mixed-methods research design with an Exploratory Sequential approach was employed, involving 60 fifth-grade students. Quantitative data were analyzed using MANCOVA to assess the intervention's impact on dependent variables simultaneously. The results indicate a highly significant difference between the experimental and control groups. The experimental group’s post-test HOTS score reached 82.5, significantly outperforming the control group’s 65.0. Similarly, in Fluid Creativity, the experimental group achieved 78.4 compared to the control group’s 58.2 (p < .001). Specifically, the haptic group showed sharp increases in high-level cognitive indicators: Analysis (Gain 38.6) and Evaluation (Gain 36.4), with a substantial Effect Size of 0.42 (Partial Eta Squared). These findings empirically confirm that physical re-materialization serves as a "cognitive prosthetic," bridging the gap between abstract concepts and physical reality through sensorimotor feedback. This study concludes that activating the hands as "thinking senses" is crucial for developing embodied knowledge and adaptive creativity in primary education.
