ABSTRACT
This study aims (1) to improve the quality of the mathematics learning process, (2) to develop students' mathematical creative thinking abilities, and (3) to get better learning outcomes by applying lesson study based problem-solving learning models. This type of research is a classroom action research study involving 32 students of class VIII.2 SMP Negeri 18 Bengkulu in the 2019-2020 school year. Data collection was carried out using tests and interviews. Data were analyzed using descriptive methods. Based on the results of data analysis the following results are obtained (1) lesson study based problem-solving models have a positive impact on students 'mathematical creative thinking abilities (2) the learning process is undertaken can improve student learning outcomes (3) improve students' ability to better understand learning activities and the ability to apply ways of solving problems in all types of problems encountered, and (4) enhance student learning activities. Based on the results of this study, it is recommended to apply the lesson study-based problem-solving model on the subject or other subjects.
