Algebraic Learning through Caring Community Based On Lesson Study for Learning Community

Algebraic material is still considered difficult by many students, especially for those in junior high schools. They still find it difficult to understand and solve algebraiv problems. This happens because their level of understanding for algebraic material is still low, therefore it takes the participation of many parties, including peers and parents, to overcome this problem (caring community based learning). This study aims to improve the students' understanding of the algebraic concept and to minimize the errors that occur in solving algebra problems. The study was conducted in 3 cycles, each cycle consisted of 3 phases, ie plan - do - see, in accordance with the learning cycle in the lesson study. The subjects of this research were 32 students of VII G class of MTs Negeri 2 Jember in the 2017/2018 academic year. Data collection techniques used were observation, tests and documentation. The data were analyzed using descriptive qualitative method through three steps: data reduction, data presentation and conclusion. The results showed that there was a high confidence increase in learning among the students and the “care” occured in the learning process. The students' understanding and mastery of algebraic material were also improved through caring community based lesson study for learning community.
