The aim of this research is to examine the effects of various variables (cognitive flexibility, school achievement. physics course success, gender, popularity. family income level) and communication that occur between students in the problem solving process of the high school students. The research, which was designed according to the mixed research approach, was carried out with 80 tenth grade students determined by high school education and purposive sampling. It is given in research; the problem form was obtained by cognitive flexibility scale and observations. the discourses obtained from the observations were coded, and the data obtained from the other variables were categorized. Problem solving situation is coded with rubric in accordance with ordinal variable. Data is analyzed by modelling with multi-level sequential logistic regression and sequential logistic regression analysis. Findings showed that obtaining a creative solution to the problem is related to the success of the physics course related to solution of the problem rather than the general academic achievement, it is related to cognitive flexibility level, gender, family income level. The higher the level of cognitive flexibility and the level of family income. the higher likelihood of reaching creative solutions. The probability of women reaching creative solution is lower than men. The number of discourses and rudely disagreeing discourses in schools with low achievement levels are higher than those of successful schools. While presenting suggestions that are modelled as descriptive in reaching creative solutions, discourse of ignorance is meaningful variable; approval, politely disagreeing. rudely disagreeing are not meaningful variables.
