COMPARISON OF PHYSICS CONCEPT UNDERSTANDING ABILITY OF STUDENTS USING PHET SOFTWARE WITH NI MULTISIM SOFTWARE

Abstract

The lack of practical equipment for physics in schools is a contributing factor to the absence of practical. This study aims to determine the differences in understanding of the concepts of students in the control class and experimental class 1 and for differences in understanding the concepts of students in experimental class 1 and experimental class 2. The research methodology involves a quasi-experimental approach employing a nonequivalent control group design. The target population consists of all students at XII IPA SMA Negeri 8 Banda Aceh. The sample for the study is derived using purposive sampling technique. Data collection is accomplished by employing essay test instruments. The independent sample t-test is utilized to assess the difference in concept understanding ability among the three classes, with a significance level of 0.05 after meeting the prerequisite test. The study findings reveal a significant disparity in concept understanding between the control class and experimental class 1, with a t_count value of 12.049 > t_table 2.068. Additionally, there is a notable difference in concept understanding between the control class and experimental class 2, with a t count value of 13.931 > t_table 2.068.
