Concept Maps as a Tool for Teaching Organic Chemical Reactions

Barbara Šket, Saša Aleksij Glažar, Janez Vogrinc


The purpose of the research was to establish the impact of the application of a concept map in chemistry lessons on the effective solving of tasks with organic reactions content. In the first phase of the research, a concept map was produced representing the reactions of hydrocarbons, organic halogenated compounds and organic oxygen compounds, and in the second phase the produced concept map was introduced in lessons. Its impact was tested on a sample consisting of 186 students (average age of 17.8 years), who were divided into a control group (88 students) and an experimental group (98 students). Prior to the experiment, the two groups were equalised in terms of their level of development of formal logical thinking and their average grade in chemistry. A knowledge test, consisting of five problem tasks comprising multiple parts, was used as a quantitative instrument for measuring the impact of the applied concept map. The content of the knowledge test was selected on the basis of the chemistry lesson plan (reactions of organic oxygen compounds) for general upper secondary schools (in Slovenian: gimnazije). An analysis of the task solving showed statistically significant differences in the responses of the experimental group members and the control group members (experimental group M = 15.9; SD = 6.33; control group M = 13.6; SD = 7.93; p = 0.03). The produced concept map contributed to the more effective interrelation of concepts and, consequently, to more effective problem task solving.
