Abstract

Improving cognitive learning outcomes can be assisted by problem-based learning (PBL) based on Lesson Study (LS), where in the characteristics of PBL there is a question posed as a problem for students to work on. LS is learning through collaboration of subject teachers in discussing the direction of learning objectives in finding suitable learning strategies or methods to help achieve learning objectives.

This learning activity was carried out using 2 learning cycles, with the acquisition of scores in cycle I amounting to 62.1% and cycle II amounting to 92%. The results showed an increase in students' cognitive learning outcomes. Furthermore, the N-Gain test was carried out with a value of 80.19% with the interpretation of "effective", and the results of the division of the N-Gain score, which is greater than g> 0.7, namely with a value of 0.80 with a "high" category. Based on the results of these calculations, it can be concluded that.
