	abstract = {This study addressed teachers{\textquoteright} perceptions of the effect of online teacher professional development programs (OTPDPs) on their professional development. This five-month study focused on four aspects of OTPDPs: (1) Teachers{\textquoteright} perceptions on OTPDPs, (2) the impact of OTPDPs on lesson planning, (3) the impact of OTPDPs on STEM teaching, and (4) the impact of OTPDPs in STEM education on teacher employment. The sample consisted of 36 teachers. An OTPDP tailored to STEM education was designed to help participants develop professional skills. This study adopted a qualitative type of research, which was a single case study.{\textquotedblright} Data were collected through interviews, videotapes, and lesson plans. The data were analyzed using content analysis. Participants had positive perceptions about OTPDPs. They stated that the OTPDP helped them plan and teach STEM better and gain pedagogical and content knowledge. It also allowed them to acquire technological self-efficacy. They also noted that OTPDPs helped teachers develop the skills that would make them more likely to be employed in the future. The results indicate that technological self-efficacy and Internet access are of paramount importance for effective OTPDPs.},

The use of movies may enhance students{\textquoteright} interest in science, technology, engineering, and mathematics (STEM). They can be effective tools to build students{\textquoteright} interest in STEM fields and raise their awareness of STEM and STEM careers. This study purpose was to identify STEM-related topics in the movie {\textquotedblleft}Hidden Figures{\textquotedblright} and determine preservice female teachers{\textquoteright} views of it. The study sample included 19 female students. A qualitative phenomenological design research method was used. Data were collected using {\textquotedblleft}the Movie Hidden Figures{\textquotedblright} and a {\textquotedblleft}Semi-Structured Interview{\textquotedblright} forms. Qualitative data were analyzed using semiotics and content analysis. Analysis showed that Hidden Figures focus mostly on the theme of {\textquotedblleft}gender perception in science{\textquotedblright} as well as {\textquotedblleft}design process{\textquotedblright} and {\textquotedblleft}advances in technology.{\textquotedblright} Participants believed that the movie had messages mostly of negative gender perception in science. Despite that, movies emphasized that women can be mathematicians, engineers, and scientists as men. They also stated that gender equality is crucial in education. They also advocated that mathematics and engineering are essential for technological progress and female scientists can play a more active role for achievement.},

This research has been carried out by 29 mathematics pre-service teachers who are schoolers at the educational faculties of Mus Alparslan University. The research was completed in 10 weeks (3 hours per week) in spring semester of 2016-2017 academic year. Mixed research approach was used in the study. "Mathematical Literacy Self-Sufficiency Scale", "Mathematical Thinking Scale", "Technological Pedagogical Area Information Scale" and "STEM Interview Form for Mathematics Pre-service Teachers" were used as data collection instruments. The collected data were analyzed, and it was certain that the STEM applications positively affected the pre-service teachers{\textquoteright} mathematics literacy self-efficacy and technological pedagogical content knowledge. However, STEM applications were not seemed to have a positive effect on mathematical thinking. Moreover, when the opinions of the pre-service teachers were examined, it was identified that the STEM applications changed positively the opinions of the pre-service teachers about the mathematical literacy, and that they lacked many subjects such as field knowledge and pedagogy knowledge about STEM education. Suggestions were made in the direction of the findings obtained. },
