Abstract

The research aims to improve the activity and learning outcomes of physics subject matter for the law of thermodynamics for class XI IPA-1 SMA Negeri 1 Siborongborong Semester 2 of the 2020/2021 academic year. The research was carried out in two cycles and each cycle consisted of four stages, namely planning, action, observation, and reflection. The research subjects were 36 students.
