Content analysis of 13 dimensions to support student teachers' PCK in the environmental chemistry textbooks

Abstract

Environmental chemistry courses in the undergraduate program is an important subject to link many concepts of chemistry and environmental sciences. Content analysis was used by the researchers to determine textbooks compatibility using 13 dimensions of content knowledge. We examined three textbooks often used as references to discuss environmental chemistry issues in the courses. We specify the analysis in the chapter on wastewater. This chapter is a very important chapter to develop trainee teachers' competencies either as teacher or scientist. We labeled each book with codes of R, S, or T with Kappa coefficient of 82.7, which means no significant differences in perception about observed aspect among researchers. The textbooks only present material-related subjects. Not all dimensions in the content knowledge contained in the textbooks, only dimensions related to basic knowledge.
