Online Science Education Journal, 3(2): 15-25. ABSTRACT Argument is defined as a whole of claim that have presumptive relationships with each other. Argument map, on the other hand, is used in visually presenting arguments that have a presumptive structure with the help of graphical techniques. Argument maps help individuals to visualize and evaluate reasoning processes. In learning environments, argument mapping helps to establish connections between the data and think at a higher level. The purpose of the study is to enable preservice science teachers to create individual and interactive argument maps using the RationaleTM program within the scope of the subject of lenses. Argument mapping process was realized on the basis of “RationaleTM”, which is an online computer program. The aforementioned program allows us to examine argument maps that are taught in the subtopic of “Lenses” in the subject of “Optic” at higher education level. Also, discussions were made concerning how to use argument mapping in learning environments and examples of relevant argument maps were presented within the scope of the study.
