ABSTRACT
Regulation of the Minister of National Education Number 16 of 2007 mandates that every teacher should develop their profession sustainably by reflecting on learning and improving the quality of their learning through classroom action research. However, in reality teachers have difficulty in implementing this because of a lack of understanding of classroom action research methodology and experience in conducting it. The purpose of this activity is to improve teachers’ understanding and experience in improving and reflecting on the quality of learning. A lesson study was conducted involving Indonesian teachers. With this lesson study, teachers’ creativity was found to improve when reflecting on learning, they designed better learning, and learning increased. In addition, teachers become more confident in carrying out learning.
