The learning process having done by teachers, just uses a conventional learning model in presenting the material so that not all students are interested to pay attention to teachers' explanator. Based on this problem, researchers deal with the problem by implementing guided inquiry learning model to achieving optimal learning outcomes and build learning experiences so that students can be more active with the guidance of a teacher. This study uses Classroom Action Research (PTK), which is conducted through three cycles and four stages, that is: (1) planning, (2) action, (3) observation, and (4) reflection. This study was conducted on 11 to 28 March 2013. The subject of this research is students from grade four in B class SDN 99 Pekanbaru, which consists of 30 students. Data analysis techniques observation froms of teacher’s activities, and student activities undertaken during the learning process and test for students' understanding through daily tests on each cycle. These results indicate that the application of Guided Inquiry Learning Model Improved Student’s Learning Outcomes on Mathematics in grade four at B Class in SDN 99 Pekanbaru. It can be seen from the data that student’s average student on the basis score is 55.67, daily test in cycle I is 70.83, daily test in cycle II is 76.16, and daily test in cycle III are 87 students, in which the average of student learning outcomes improved, so that the classical completeness in the their cycle is 86.67% and student learning outcomes achieving individual completeness is 26 students.en-USApplication of guided Inquiry Learning Model,Math Learning Outcomesstudent Paper Post Degree
