标题：IMPROVING STUDENTS' LEARNING OUTCOME AND MATHEMATICAL ACTIVITIES THROUGH INQUIRY LEARNING STRATEGY IN CLASS XII IPA-2 SMAN 2 BAGAN SINEMBAH 2014/2015 ACADEMIC YEAR
摘要：The purpose of this study is to examine the improvement of students' learning outcome using inquiry learning strategy and to find out the increase of mathematics learning activities using inquiry learning strategy. This study is an action research which was held at SMAN 2 Bagan Sinembah. The subject is students of Class XII IPA-2 in the academic year 2014/2015 which consists of 40 people, 11 male students and 29 female students. This study was conducted in two cycles, each consists of three meetings. A test was conducted at the beginning and at the end of each cycle in order to see students' mathematical communication ability. The results of cycle I showed that students' average score was 72.7 with 25 students complete and 15 students incomplete and the classical completeness was 62.5%. In the second cycle, the average score was 82.65 with 37 students complete and 3 students incomplete and the classical completeness was 92.5%. There was an increase of 9.5 points on students' learning outcome and hence it can be concluded that inquiry learning strategy leads students' activities to be in good category.
