Cetingul, Puren Ipek; Geban, Omer – Hacettepe University Journal of Education, 2005
This study explores changes of the tenth-grade students' conceptions about acids and bases by using conceptual change text oriented instruction accompanied with analogies. Since conceptual change is viewed not only as a process of replacement of old concepts but also a process of learning to relate ideas to appropriate contexts, the instruction…
