Abstract

The background of this research is a response to the low critical thinking skills of fourth-grade students in the IPAS (Natural and Social Sciences) subject. This condition is triggered by the dominance of teacher-centered teaching approaches and the suboptimal utilization of varied learning models and learning media within the educational environment. Therefore, this study aims to test the effectiveness and to comprehensively examine the impact of implementing the RADEC (Read, Answer, Discuss, Explain, Create) learning model in accelerating students' critical thinking skills in the IPAS discipline. Methodologically, this investigation adopts a quantitative approach utilizing a Quasi-Experimental Design, specifically the Nonequivalent Control Group Design. The main population consisted of all fourth-grade students in Gugus I Diponegoro, Surakarta. Through a cluster sampling procedure, SD Negeri Rejosari Surakarta was selected as the sampling location, wherein class IV B (26 students) was assigned as the experimental group and class IV A (25 students) functioned as the control group. The data collection process was conducted through tests, observations, documentation, and interviews. The evaluation measurement utilized was an essay test that had been proven valid and reliable. Furthermore, the data processing stage was executed using SPSS version 25 software, which included prerequisite testing (normality and homogeneity) and proceeded to hypothesis testing using the Independent Samples t-Test. Empirical evidence from this examination revealed a margin of 11.62 points, with the control group's average posttest score standing at 71.80, while the experimental group's score surged to 83.42. The Independent Samples t-Test calculation yielded a t-count of -12.589, accompanied by a probability value (Sig. 2-tailed) of 0.000 (< 0.05). This statistical figure validates the rejection of H₀ and the acceptance of Hₐ. Thus, it is confirmed that the application of the RADEC learning model brings a highly significant effect on improving the critical thinking skills of fourth-grade students in the IPAS subject. Practically, this learning framework has proven successful in stimulating students to become more analytical, cooperative, proactive, and innovative throughout the teaching and learning activities.

Abstract

This study aims to determine the effect of using Canva-based interactive video media on critical thinking skills in the science and social studies subject for fourth-grade students at SD Negeri Mojosongo 5 Surakarta in the 2025/2026 academic year. A quantitative approach with a Pre-Experimental Design was employed, using a One Group Pretest–Posttest Design. The population comprised 112 fourth-grade students, with a sample of 27 selected through Cluster Random Sampling. Data were collected through tests, observation, interviews, and documentation. The research instrument was validated and tested for reliability before use. Data analysis included a normality test as a prerequisite, followed by hypothesis testing using a Paired Sample t-Test with SPSS version 26. The results revealed that the average pretest score was 44.96, while the average posttest score was 60.56. The Paired Sample t-Test showed a t-count of 4.491 > t-table of 2.056, with a significance value of 0.000 < 0.05, leading to the rejection of H0 and acceptance of Ha. These findings indicate that the use of Canva-based interactive video media in learning facilitates students' active engagement in understanding the material and developing critical thinking skills. Thus, the use of Canva-based interactive video media has a significant effect on the critical thinking skills of fourth-grade students in the science and social studies subject.

Abstract

This study aimed to empirically examine the effect of implementing the Project-Based Learning (PjBL) model supported by digital crossword puzzle media on enhancing the creative thinking skills of fifth-grade students in Science and Social Studies (IPAS) at SD Negeri Gugus 2 R.A. Kartini Surakarta in the 2025/2026 academic year. A quantitative approach employing a quasi-experimental design with a Nonequivalent Control Group Design was used as the methodological framework. The population consisted of 165 fifth-grade students, with a sample of 53 students selected through purposive sampling, comprising 25 students in the experimental group and 28 students in the control group. Data were collected through observations, interviews, tests, and documentation. The research instrument, in the form of an essay test measuring creative thinking skills, was confirmed to be valid and reliable, with a Cronbach’s Alpha coefficient of 0.709. Prior to hypothesis testing, the data met the assumptions through the Shapiro–Wilk normality test and Levene’s Test of homogeneity, followed by comparative analysis using the Independent Samples t-Test. The findings revealed that the mean posttest score of the experimental group was higher than that of the control group, namely 71.56 and 58.25, respectively. The results of the independent samples t-test showed that the calculated t-value exceeded the critical t-value (5.061 > 2.008) with a significance value of 0.000 (< 0.05). Therefore, H₀ was rejected and Hₐ was accepted. These findings indicate that the implementation of Project-Based Learning assisted by digital crossword puzzle (Crossword Puzzle/CWP) media had a significant effect on students’ creative thinking skills in IPAS learning. This improvement was supported by the implementation of PjBL syntax integrated with digital crossword puzzle media at every stage of the learning process, encouraging students to actively participate in identifying problems, planning projects, engaging in discussions, developing ideas, and presenting project outcomes.
