In this research, the effect of inquiry-based activities on the skills of pre-service science teachers with different cognitive styles to use the word processing program according to the purpose of the science courses was examined. The research was conducted according to a non-equivalent control group model, one of the quasi-experimental designs. The research was carried out with 72 pre-service teachers studying in the science education program in the third grade at a state university in the Black Sea region in the spring semester of the 2018-2019 academic year. In order to collect the data, the Group Embedded Figures (GEF) Test and the performance-based Word Processing Test (WPT) were used. The GEF test was given to the experimental and control groups at the beginning of the research, and the WPT was used as a pre-test and post-test. The Word Processing Module (WPM), which includes inquiry-based activities, was used within the scope of the organized professional development program to develop the skills of pre-service science teachers with different cognitive styles to use the word processing program according to the purpose of the science courses. As a result of the research, it was determined that the organized professional development program contributed to the development of the skills of pre-service science teachers with different cognitive styles to use the word processing program according to the purpose of the science courses. In addition, it was stated that different variables that may affect cognitive styles should be considered.
