Research has been studied in a secondary school with 37 students in Turkey. In the research, authentic learning based education was carried out for 5 weeks in the 2017-2018 academic year. In this semi-experimental model, academic achievement and scientific process skills test, interview form, students' worksheets and observer notes were used as data collection tools. The quantitative data obtained were analyzed statistically in SPSS 20 program, and qualitative data were analyzed by content analysis. It was found that the quantitative data and the experimental and control groups differed statistically as a result of the application as an academic achievement, but did not differ according to the scientific process skill test results.
