Abstract
Heat material closely related to everyday life and it is one of the main materials of physics learning in class XI. However, students still do not understand it optimally. Meanwhile, the use of the ADI-STEM-FA model to improve conceptual understanding in heat materials is still rarely done. Therefore, the purpose of this study is to increase students^ conceptual understanding in heat material through ADI-STEM-FA learning. This study uses a mixed-method with embedded experimental design. The research was conducted in Malang with 54 students in class XI high school, which were distributed to 27 students in the experimental class and 27 students in the control class. The experimental class was taught through ADI-STEM-FA learning, which emphasizing practical activities, doing group arguments, and making prototypes of simple stove technology. When the control class was taught through everyday conventional learning. Students^ conceptual understanding was measured by 5 multiple choice questions of conceptual understanding with a reliability of 0.45. The results of the Wilcoxon difference test analysis showed that the ADI-STEM-FA model had an effect on increasing students^ conceptual understanding. This result supported by the N-Gain value in the experimental class which is higher than the control class, both overall and in each subtopic. The experimental class has an N-gain of 0.48 (medium category) in order from low to high are temperature, heat transfer, heat, and expansion. While the control class has N-gain 0.25 (low category) in order from low to high are temperature, heat, expansion, and heat transfer. In future research, it will recommend adding an ^Art^ and a ^Religious^ aspects to the STEM approach in order to obtain a better increase in conceptual understanding.
