Enhancement of Concentration and Mathematics Learning Outcomes Using Discovery Learning Method on Transformation Topic
<em>This study aims to examine whether the actions of educators in using discovery learning models can improve concentration and mathematics learning outcomes in the material of transformation in class IX D of one of the junior high schools in Magelang. This research is a participant class action research. While the models used are the Stephen Kemmis and Robin McTaggart Model. The subjects of this study were students of class IX D of one of the junior high schools in Magelang in the academic year 2018/2019. This research consists of two cycles, namely cycle 1 and cycle 2. The material provided in this study is a transformation topic that includes translation, reflection, rotation, and dilation. Data on the concentration of mathematics learning are obtained using observation sheets. Data on mathematics learning outcomes were obtained using a theory test sheet. The data obtained were analyzed quantitatively and qualitatively. The results of the study show that: (1) learning using discovery learning models can increase student learning concentration; (2) learning using discovery learning models can improve student learning outcomes; and (3) learning using discovery learning models can increase the concentration of learning and the learning outcomes of IX D students of junior high school.</em>
