Abstract
The purposes of this study were to evaluate the level of PCK which middle school science teachers have on the concept of density and to analyze the characteristics of science teachers' content representation on the concept of density by their PCK level. For that purpose, 20 science teachers were selected and asked to answer the questionnaire on the eight aspects of CoRe. Results of this study indicated that the science teachers' PCK levels were low in general and evaluated as below average. The differences among the characteristics of science teachers' content representation by their PCK level were high in seven aspects of CoRe but the one aspect of the understanding of learner's preconception. These differences were analyzed and the patterns shown by the science teachers in eight aspects of CoRe were drawn in this study. It was also found that the characteristics drawn in eight aspects of content representation shown by the teachers whose PCK level was medium were close to those whose PCK level was low rather than high in most aspects of CoRe.
