The research was carried out on the 6th grade students in a secondary school in the province of Samsun. In the research, exploratory order model, one of the mixed method research designs, was used. There were 44 students in the experimental group and 41 students in the control group. "Academic achievement test" was used for data collection. The second phase of the study was designed as a case study and a semi-structured interview form was used to collect data. The interview form prepared for 10 students in the experimental group was applied.

Descriptive analysis method was used in the analysis of qualitative data.
