Abstract

The purpose of this research is to know how the Contextual Teaching and Learning with Learning Community method is able to increase the mathematics learning outcomes and critical thinking skills of students at SDN Salatiga 05 and describing the implementation of Learning Community method. The research type is collaboration classroom action research. And the subject of this research is the fourth grade students at SDN Salatiga 05 consist of 20 students. This research did on March 2019, that consist of pre-cycle, cycle one, and cycle two. Each cycle consist of action planning, action implementation, observation, and reflection. The research instrument for collect the data such as observation sheets and an evaluation test analyzed quantitatively. Observation sheets have purpose to know how the Learning Community that apply on the class can give the good benefit for the students. Classroom teacher have an opportunity to give the value and comment during the learning process for repairing on the next cycle. In the evaluation test students get some test during the cycle one and cycle two, it have purpose to know how the Learning Community can increase the learning outcomes for the students. And that approve on the result of academic, from pre-cycle to cycle one there is 30% increased. And also it show the significantly result on the cycle two that was 40% increased. The reason researcher used the Learning Community method are, first is want to focus on learning independently for the students, second is concern on critical thinking of students that need to be increased. It can be seen on the background of the research if the students are not really pay attention during the learning process and it is like they have their own world. From those things researcher put them on the group of learning that has different role one and another, it help to increase their responsibility, give some group activity in the classroom, have the students to share the result from group project with another team used pairs discussion. The condition of the learning process was little by little conducive until the students really enjoy and enthusiasts join in the activities. The students show the improvement during the cycle one to cycle two by did a great job on their role. Thus Learning Community method was implemented for the students and get the good result for learning outcomes and critical thinking of the students.
