This Lesson Study mentoring activity aims to improve the quality of learning mathematics by using a contextual approach oriented to Minimum Competency Assessment. This mentoring activity used workshop and simulation methods. Four mathematics teachers attended the workshop and simulation. The results showed that the Lesson Study team produced a Minimum Competency Assessment for six grade 7 groups oriented contextual learning design that integrated students’ involvement in creative and critical thinking, communication, and collaboration, which was realized through lesson design. Model teachers and observers were enthusiastic and carried out Minimum Competency assessment-oriented contextual learning activities through Lesson Study well. Students gave a positive response and were very active while participating in learning. The mentoring activities of Minimum Competency Assessment-oriented contextual learning can be said to be effective. The learning designs prepared by the teacher can be implemented in other classes with relatively the same student characteristics.]]>
