The Effect of the Flashcard-Assisted Group Investigation Type Cooperative Model on Learning Outcomes and Critical Thinking of Grade III Students in the IPAS Subject

Problems faced in science learning at SDN Kutorenon 01 include suboptimal student learning outcomes, weak critical thinking skills, teachers being the center of learning, limited use of textbooks as teaching materials, and the use of less innovative learning models and media. Therefore, this study aims to examine the effect of the Cooperative Group Investigation Model accompanied by Flashcards on the learning outcomes and critical thinking of third-grade students in the subject of science. This study is an experimental study (True Experimental) using Pretest-Posttest Control Group Design with third-grade students of SDN Kutorenon 01. The measuring instrument used is a test, which is expressed in the form of scores obtained from the results of the students’ pretest and posttest. Data analysis uses a t-test or independent sample test with the help of SPSS 27 for Windows software. The results of the data analysis show that the learning outcomes and critical thinking of students in the experimental class are higher than those in the control class. This is supported by the hypothesis test calculations, which state that student learning outcomes reached a significance value (2-tailed) of 0.000 and critical thinking skills reached a significance value (2-tailed) of 0.000, both less than 0.05. This proves a difference in the average learning outcomes and critical thinking skills of students in the experimental and control classes. Thus, it can be concluded that the cooperative investigation-type group model assisted by flashcards has a significant influence on the learning outcomes and critical thinking skills of third-grade science students.
