Abstract
Turkish science teachers' in‐service needs and the effects of teacher and school demographic variables on these needs are examined in this study. In addition, major barriers that prevented science teachers from attending in‐service programmes are investigated. The data for the research were gathered through a survey. This study shows that Turkish science teachers require more instructional materials, laboratory equipment, computers, and software and need in‐service education to integrate these instructional facilities into their lessons. This study also indicates that teacher and school demographic variables have little significance in predicting science teachers' needs.
