Abstract

A preliminary study on the possibility of developing representational competence pre-service chemistry teachers has been done. The aim of this descriptive study was to provide the description of representational competence's profile of pre-service chemistry teachers in chemical problem solving and to give consideration about the learning strategy have been conducted. The results showed that most students were unable to provide explanations relating to the representation of sub-microscopic level, which exist between the macroscopic and symbolic levels of representation. There was tendency those students solved problems using a transformation from the macroscopic to the symbolic level of representation and vice versa. Although they should give the explanation at the sub-microscopic level of representation, they did not understand the role of sub-microscopic representation to explain the macroscopic level or transformed into the symbolic level. Presumably, the lack of student representation competence, because the lectures were held tend to separate the three levels of representation and influence the learning process, which they experienced in senior high school. Those problems need serious efforts to find the solution.
