The effectiveness of critical thinking training on problem solving styles (efficient and inefficient) of students

The purpose of this study was to determine the effectiveness of critical thinking training on problem solving (efficient and inefficient) of students. The research method was quasi-experimental with pretest-posttest design and a control group. The population included all first grade high school students of District Two in Ardabil during 2015-2016 academic year. By using random cluster sampling, 60 students were selected and randomly assigned to the experimental group (30 individuals) and control group (30 individuals). The experimental group received 6 sessions of critical thinking training program. Dzorila, Nezoo & Mead-Olivers (2000) social problem solving inventory was used to collect the data. The data were analyzed by multivariate covariance. The results indicated that the research hypothesis of the effect of critical thinking training on problem solving of students was verified. So, the average post-test scores of the students in the experimental group compared to the control group was significantly high in the efficient problem solving style (positive orientation to problem and rational style of problem solving) and less in the inefficient problem solving style (negative orientation to problem solving, avoidance style and impulsive style of problem solving). Therefore, we can conclude that critical thinking training has a significant effect on improving efficient problem solving style of students.
