In this paper, the main purpose is to describe the development and use of three flowcharts for identifying types of isomers and naming coordination compounds. The first flowchart is designed to help students identify the type of isomers between the two coordination compounds. The second one is is designed to identify the type of stereoisomerism. Students can then name one of the coordination compounds through the third flowchart. Ten second-year preservice chemistry teachers attending an Inorganic Chemistry II course participated in the study. It has been demonstrated in practice that these flowcharts could influence preservice chemistry teachers' ability to identify types of isomers and their knowledge of nomenclature for coordination compounds. Participants' views about the flowcharts indicated that they are very effective tools.
