The sample of study was composed of three 6th and three 7th graders attending øhsan Koz Primary School in
Trabzon Province Center in the spring term of 2008-2009 educational year. Concerning the classroom teachers’
comments, the students were chosen so as to represent one high, one middle and one low achievers from both
grades. In order to detect student misconceptions, clinical interviews were conducted. In clinical interview
technique, whether the student learn the concept can be investigated deeply while he/she is being interviewed about
a situation or an event. In some cases, students are asked to define a concept and in addition they are expected to
answer and explain why they reach that idea. The explanations by students reveal students’ understanding criteria. In
these interviews the exchange starts with starter questions and by making students focus on the topic or the concept
which will soon be given. Then it goes on with questions about a range of pictures (White & Gunstone, 1992). This
study is also carried out with prepared “question cards”. Concerning the misconceptions remarked by the related
literature, question cards was prepared along with the results of the interviews with 4 expert Science and
Technology Course teacher working for different primary schools. The cards took their final form with expert
opinions. The procedural stages of this study are presented in the algorithm chart in Figure 1.
