The influence of mobile instant messaging with scientific approach on students’ critical-thinking skills in physics learning during covid-19 pandemic

Abstract The purpose of this study was to determine the influence of Mobile Instant Messaging with the scientific approach on critical-thinking skills on physics learning during the Covid-19 pandemic. The research method used was a quasi-experimental research with a non-equivalent control group design. The population of this study was all eleventh-grade science students Senior High School Bandar Sribhawono. The sampling technique used the purposive sampling technique. The instrument used a test in the form of essay questions to measure students’ critical-thinking skills. Based on the critical-thinking skills, the experimental class and control class obtained 72.60% and 61.30% in the basic support indicator. In elementary clarification indicator, the experimental class and control class obtained 64.40% and 51.90%. In advanced clarification indicator, the experimental class and control class obtained 62.20% and 45.30%. Indicator of inference, the experimental class and control class obtained 67.90 and 46.40%. Indicator of strategy and tactics, the experimental class and control class obtained 66.40% and 46.09%. The score of students’ critical thinking skills in both classes was tested with the independent sample t-test with the obtained sig value of 0.001 <0.05. Thus, Ha was accepted which indicated that the students were able to think critically.
