Pengaruh Penggunaan Papan Interaktif Digital terhadap Kemampuan Berpikir Kritis pada Mata Pelajaran IPAS Siswa Kelas IV UPTD SDN Pondok Cabe Udik 02 Tangsel

Abstract

This study was motivated by the low critical thinking skills of fourth-grade students at UPTD SDN Pondok Cabe Udik 02, South Tangerang. The study aimed to determine the effect of using a digital interactive board and to measure the magnitude of that effect. A quantitative research method was employed, specifically a quasi-experimental design using the Nonequivalent Control Group Design. The study population consisted of 60 students, selected via a saturated sampling technique. The sample comprised 30 students in the experimental class and 30 students in the control class. Data collection involved critical thinking skills tests in the form of pretests and posttests. Data analysis was conducted using normality tests, homogeneity tests, N-Gain tests, and hypothesis testing (Independent Sample t-Test) via SPSS version 25. The results showed that the average score of the experimental class rose from 55.83 (pretest) to 83.17 (posttest), while the control class score increased from 42.50 (pretest) to 71.50. The N-Gain score was 0.5836 for the experimental class and 0.2142 for the control class. Hypothesis testing yielded a significance value (Sig. 2-tailed) of 0.000 (< 0.05), leading to the rejection of H₀ and the acceptance of Hₐ. Thus, the use of a digital interactive board has a significant effect on the critical thinking skills of fourth-grade students at UPTD SDN Pondok Cabe Udik 02, South Tangerang. The study implies that digital interactive boards can serve as an alternative instructional tool to enhance the critical thinking skills of elementary school students.
