The purpose of this study was to diagnose the misconceptions held by preservice physics teachers about force and motion. The secondary aim of the study was to detect whether misconceptions vary according to gender, educational level, and culture. The study was conducted with 79 student-teachers attending to one of the largest faculties of education in Turkey. Force Concept Inventory (FCI) was used to diagnose studentteachers' misconceptions. FCI is a conceptual test consisting of 29 multiple choice items. Each wrong choice for each question reflects a specific misconception about the force and motion concepts. Data from the study was analyzed by using frequencies, t-test, and ANOVA for making comparisons according to gender and years of education. Results of the study showed that student-teachers of physics hold very strong misconceptions about impetus and active force. No significant differences were found between male and female students' scores on the concept test. The results also showed that misconceptions about force and motion decreased through the years of education. However, they did not disappear completely. Findings of the study are very similar to the other research findings conducted on the subject in other countries. Student-teachers' conceptions about Newton's Third Law, on the other hand, were significantly better than those observed in other research done in other countries such as the US and Finland.

The main purpose of this study was to investigate the effectiveness of a primary teacher education program in improving science teaching efficacy beliefs (personal science teaching efficacy beliefs and outcome expectancy beliefs) of preservice primary school teachers. The study also investigated whether the program has an effect on student teachers' attitudes toward science. Data were collected by administering the “Science Teaching Efficacy Beliefs Instrument” and “Attitudes toward Science Scale” to 282 preservice primary teachers (147 freshmen, 135 seniors). Statistical techniques such as means and t‐test were used to analyze the data. Results of the study showed that the primary teacher education program has a medium positive effect on science teaching efficacy beliefs of the primary preservice teachers (t = 4.791, p = .000) and that there were no gender differences in terms of efficacy beliefs. Results also indicated that preservice primary teachers' attitudes toward science were moderately positive and differ by class level. Fourth‐year preservice teachers' attitudes toward science were found to be significantly more positive than the first years (t = 5.494, p = .000). There were no gender differences in attitudes toward science.
