The Effectiveness of Flipped Instruction Method on Disposition Toward Critical Thinking of Students

The current research was conducted with the aim of determining the effectiveness of flipped instruction method on disposition toward critical thinking (innovativeness, cognitive maturity and mental engagement) of students. The research method was semi-experimental with a pre-test-post-test design with a control group. The statistical population of the research was made up of all the female students of the ninth grade of the first period of high school in the academic year of 2020-2021. To select the sample, first, using the available sampling method, two schools were selected from among the first secondary schools. Then, a 9th grade class was selected from each school and using random sampling method, the students of one of the classes were determined as the experimental group and the students of the other class as the control group. The students of the experimental group were taught using the flipped instruction method. Ricketts' (2003) critical thinking disposition questionnaire was used to collect data. The data were analyzed using the statistical method of analysis of covariance. The findings showed that the flipped instruction method was effective on disposition toward critical thinking (innovativeness, cognitive maturity and mental engagement) of students and increased the disposition toward critical thinking (innovativeness, cognitive maturity and mental engagement) of students in experimental group. Therefore, the research hypothesis was confirmed (p<0.01). According to the results of this research, it can be concluded that the use of the flipped instruction method by teachers can be effective in increasing the disposition toward critical thinking (innovativeness, cognitive maturity and mental engagement) of students, and as a result, it can lead to better performance of students. In fact, the reverse education method is an effective way of teaching and learning in the world, which should become part of the comprehensive lifelong learning system in schools.
