The effect of design based science education applications of science teacher candidates on their perceptions of engineering education and engineer
The purpose of this study was to determine the effect of Design Based Science Education (DBSE) applications on the perceptions of science teacher candidates about engineering education and engineers. In the quantitative part of the study in which the mixed method was involved, a semi-experimental design with single group pre-test post-test was used while a case study design was adopted in the qualitative part of the study. The study group of the research consisted of 52 juniors who were receiving education at a university in the Aegean Region in the 2016-2017 academic year. The quantitative data of the study were obtained through the 'Engineering Education Survey' and the qualitative data through 'Draw an Engineer Test.’ The quantitative data were analyzed using a statistics software program and the qualitative data through content analysis. It was determined as a result of the study that DBSE applications positively affect the perceptions of teacher candidates about engineering education and engineers. It was also determined that the teacher candidates' stereotypical perceptions about engineers being male and working on their own decreased and their perceptions about the work area and activities of engineers changed in a positive manner. In the light of the findings obtained in the study, the importance of design based applications in STEM education was underlined.
