摘要:The primary science curricula have strong constructivist elements since 2000 in Turkey. As the creator of the learning environments it is the teacher who determines its quality. The purpose of this research is to determine if science teachers’ behaviour and thoughts are consistent with what the primary science curriculum in essence offers. The research was conducted with two researchers based on a qualitative design consisting of observation and interview with primary science teachers of Turkey. At the end, it was found that, although science teachers have constructivist ideas they do not behave in constructivist manner in the classroom.
