摘要:AbstractToday, there is unprecedented attention to critical thinking. Teacher's correct perception of teaching methods has a key role in students’ disposition to critical thinking. So this study aiming to effect collaborative learning on students’ disposition to critical thinking in high school. This study is quasi-experimental design of pre-test and post-test. Findings showed that there was significantly different between the pre-test and post-test in disposition critical thinking (t=-4.27,p=0.000) and creative component (t=-5.92,p=0.000) But, in the maturity(t=-1.21,p=0.235) and commitment components(t=-1.17,p=0.252) there wasn’t significant different between the pre-test and post-test. According to these findings, we suggest applying collaborative learning in curriculum.
