Problem solving is part of 21<sup>st</sup> century skills which is recommended by Kerangka Kurikulum Nasional Indonesia (Indonesian National Curriculum Framework). This study starts by operationalizing the direct instruction model syntax and including the argumentation strategy in form of teaching material, then implementing the strategy using a valid teaching material. In order to see the effectivity of learning strategy, the implementation is done to 92 Physics teacher students in Faculty of Teacher Training and Education Lambung Mangkurat University who are registered in Thermodynamics module as the research subject. Pretest and posttest are conducted to gain data of strategy effectivity in improving students}, number={3}, journal={International Journal of Sciences: Basic and Applied Research (IJSBAR)}, author={Arifuddin, Muhammad and Mastuang, Mastuang and Mahardika, Andi Ichsan}, year={2017}, month={Sep.}, pages={348–353} }
