Improving Mathematics Learning Outcome through Realistic Mathematical Learning at 5th Grade Students

Learning will be meaningful if the teacher involves the students directly in the learning process. The observation showed that the teacher had not involved the students yet directly in the learning process so mathematic achievement result of students is still low. This research aimed to increase students’s mathematic learning achievement with realistic mathematic learning for fifth grade class of SD N Ngluwar 1 Kecamatan Ngluwar Magelang. This research was a kind of classroom action research which was collaborated with the teacher. This research design used modified Kemmis & McTaggart model in 2 cycles consisting of planning, action, observation, and reflection. The subject of the research is 37 fifth grade students. The object of the research is mathematic achievement result with realistic mathematic learning. Data collecting techniques are test and observation. Data analysis techniques are quantitative description and qualitative description. The research showed that applying realistic mathematic learning in mathematic learning process of arithmetic operation material can improve process quality and mathematic learning achievement. Learning quality process was reflected on the improvement of students’ participation percentage in the first cycle from 74,39% to 88,56% in the second cycle. The improvement of mathematic learning achievement can be found in pre action step showing 8 students (21,62%) had achieved minimum mastery criteria then it became 19 students (51,35%) in the first cycle and 32 students (86,5%) in the second cycle.Keywords: mathematic learning achievement, realistic mathematic learnin
