Abstract

The purpose of this research is to use a Rasch model analysis to determine how integrating RADEC (Read, Answer, Discuss, Explain, and Create) learning in schools influences students' ability to think critically about the topic of locomotion. This descriptive research is a quantitative study conducted in early 2023 with a sample size of 29 students. The results of the pretest and the posttest were collected, and the Rasch Stacking Analysis method was used to examine them. The implementation of the RADEC learning paradigm (Read, Answer, Discuss, Explain, and Create) improved the critical thinking skills of students of all ability levels, according to the findings. Reading, Analyzing, Discussing, Explaining, and Creating (RADEC) trains students for independent and group learning. Starting from reading to the last stage, namely making free work through problem-solving activities carried out so that students are trained in high-order thinking skills. Students' high-level thinking skills have improved to the very excellent, good, and enough categories after participating in learning utilizing the RADEC paradigm. The difference between the logit readings before and after the test demonstrates this improvement. Applying the RADEC learning model to students' higher-order thinking skills shows that students experience improvement, as seen from the results of the pretest and posttest, which are processed using the Rasch stacking analysis model. Students are trained in high-order thinking skills students with high level.

Abstract

This study aims to determine the effect of using comic media in the Team Games Tournament (TGT) learning model on improving the science literacy of elementary school students on the topic of animal life cycle. Science literacy is an essential skill that should be fostered from an early age. This quantitative study employed a quasi-experimental pretest-posttest control group design involving 48 third-grade students at SDN Duren Tiga 13, South Jakarta, divided into an experimental class (21 students) and control class (27 class). A 25 item multiple choice instrument was used, analyzed using the Rasch model via the Winstep application. Results showed that 20 out 21 students (95.24%) in experimental goup improved, while only 1 declined. In contrast, only 18 of 27 students (66.70%) in control class improved, with 4 remaining unchanged and 5 declining. An Independent sample t-test confirmed a significant difference between the groups, t(46) = 2.973, p = 0.005. these findings indicate that integrating comic media with the TGT model learning effectively enhance students’ science literacy and may serve as an engaging alternative to conventional instruction.
