    Turkish adaptation of questionnaire on attitudes towards engineers and scientists
    (International Electronic Journal of Elementary Education, 2017) Ergün A.; Balçın M.D.
    The aim of this research was to present the Turkish adaptation of the survey for Middle-School Students’ Attitudes toward Engineers and Scientists prepared by Lyons, Fralick and Kearn (2009) 32 items in a 5-point Likert type scale. The questionnaire was administered to 707 students receiving education in the fifth, sixth, seventh and eighth grades in state schools in the Ministry of National Education. Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA) were used to examine the structural validity of the questionnaire. SPSS 21 and LISREL 8.7 software were used for EFA and CFA, respectively. A structure consisting of 22 items and two factors, and accounting for 41.88% of total variance was obtained after the EFA. To evaluate the questionnaire’s reliability, Cronbach’s Alpha internal consistency coefficient, corrected-item total correlation and the significance of differences between item averages of meta-groups and subgroups (27%) were evaluated using t-test. Cronbach’s alpha internal consistency coefficient was found to be .83 for the overall questionnaire. As a result of the study, the Turkish adaptation of the questionnaire, prepared for determination of secondary school students’ attitudes towards scientists and engineers, was conducted and a valid and reliable measurement tool was obtained. © 2017 Published by T& K Academic.

    The effect of design based science education applications of science teacher candidates on their perceptions of engineering education and engineer
    (Pegem Akademi Yayincilik Egitim Danismanlik Hizmetleri, 2019) Ergün A.; Kiyici G.
    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. © 2019, Pegem Journal of Educational and Instruction.

    Identification of the interest of Turkish middle-school students in stem careers: Gender and grade level differences
    (Scientia Socialis Ltd, 2019) Ergün A.
    In Turkey, it is predicted that the need for STEM employment in the 2016-2023 period will be close to one million and that about 31% of this need will not be met. Therefore, the identification of students’ interest in STEM careers in middle-school is regarded as important. The aim of this research was to identify the interest of middle-school students in STEM careers. The sample of the research was made up of 892 students who received education in four middle-schools in the Aegean region of Turkey. In this research which was of the descriptive survey model, the STEM Career Interest Questionnaire was used to collect data. As a result of research, it was determined that the interest of male students in STEM careers is more positive compared to the female students. It was found that the interest in careers in terms of grade level did not display any differences in the area of technology, whereas it displayed differences in the areas of science, engineering and mathematics. In addition, it was identified that the interest in STEM careers displayed differences in terms of grade level and that as the grade level increases, the interest in STEM careers decreases. © 2019, Scientia Socialis Ltd.
