Abstract:

The purpose of this study was to investigate the preservice science teachers’ perceived technological pedagogical content knowledge (TPACK) on genetics. More specifically, the purpose was to examine the relationships among the components of TPACK and genetics knowledge of the preservice science teachers. Moreover, findings the effect of the demographic information on perceived TPACK was also aimed. This study was conducted with preservice science teachers who were enrolled in elementary science education department of Education Faculties of eight public universities located in Central Anatolia. 1530 preservice science teachers participated to the study. There were two instruments used in this research which were perceived TPACK questionnaire, which was later adopted by the researcher as perceived TPACK on genetics, and genetic concepts test. v Data were analyzed by using descriptive and inferential statistics. In order to answer the first research question, descriptive information about the components of TPACK was given. Correlational analyses were used to identify the relationship between each component of the perceived TPACK on genetics and their genetic knowledge. Another correlational analysis was conducted for the third research question which seeks the relationships among the components of the TPACK. Moreover, MANOVA was conducted to investigate the impact of gender and year of enrollment on perceived TPACK on genetics of preservice science teachers. The results revealed that genetic knowledge was correlated with each component except the perceived project specific technology knowledge. Moreover, there were positive significant correlations among the components of the TPACK. According to the MANOVA results, the mean scores of male and female preservice science teachers differ in five components of TPACK, namely project specific technology knowledge, pedagogical knowledge, pedagogical content knowledge, technological content knowledge and technological pedagogical content knowledge. The results of MANOVA for year of enrollment revealed that the mean ETK, GTK, PSTK, and CK scores of participants with different year of enrollment differ significantly.
