摘要：The purpose of the study was to investigate and describe pre-service elementary science teachers’ written arguments related to Mersin-Akkuyu Nuclear Power Plant in terms of reasoning mode, Toulming argumentation model and argumentation levels. A single group pre/post-test design was administered to investigate participants written arguments about Akkuyu Nuclear Power Plant. The result of the study was that when the preservice science teachers’ knowledge about the socio-scientific issues increased, their multiple reasoning modes increased too. Furthermore, it was found that the most generated argument was ecologic oriented while the least was social oriented. The result of the study also showed that when the argumentation level increased, the reasoning mode tended to increase as well.
