Penggunaan Metode Problem Based Learning (Pbl) Berbantuan Media Audio Visual Untuk Meningkatkan Hasil Belajar Matematika Siswa Sekolah Dasar

: Background research problem is the teacher in delivering the subject matter of mathematics in the form of assignments and lectures. With that result the students are less enthusiastic and active in learning and learning outcomes of students 4th grade math N Ketapang 01 becomes low. This study aims to improve students' mathematics learning outcomes and describe the steps of the methods Problem Based Learning (PBL) aided audio-visual media that are tailored to the standard process. Classroom action research consists of two cycles, each cycle consisting of three meetings. The subject of research students 4th grade N Ketapang 01, as many as 21 students. Data collection instruments using test and non test. The research instrument is a matter of essay tests, observation and observation sheet. The results showed an increase in student learning outcomes. Improving student learning outcomes seen from the average value of classical, before action is 68.7, the first cycle increased to 78.5, and the second cycle increased to 87.8. Completeness student learning outcomes in pre-cycle by 42.9%, after the implemented action first cycle increased to 76.9%, and the second cycle increased to 90.47%. So PBL teaching methods aided audiovisual media adapted to the standards process can improve students' mathematics learning outcomes. Suggestions in the study are expected teachers can apply the methods of PBL aided by audio-visual media in improving student learning outcomes in mathematics, student activity in learning increases, adding the work in the school library, can complement the weaknesses of previous studies and discover new things, namely the application of PBL aided media EEK-based audio-visua
