PENINGKATKAN KEAKTIFAN DAN HASIL BELAJAR MATEMATIKA SISWA KELAS 8 A MTS NEGERI 1 PATI MELALUI PEMBELAJARAN DENGAN MEDIA GEOGEBRA

Classroom action research in general aims to improve the quality of learning 8th grade MTs N 1 Pati learners. Research is carried out two cycles, where each cycle consists planning, implementation, observation, and reflection stages. Cycle I 2 consist encounters. Student activity data dug up with a Learner's Liveliness Observation Sheet, while student's outcome Learning Outcome Test. This includes type classroom (PTK), its main characteristic being repeated actions method self-reflection aimed at improving learning. PTK problem-solving characterized by cyclic that starts from: a) b) actions, c) observing, d) analyzing data/information decide extent advantages disadvantages such (reflecting). continuous improvement so satisfaction often benchmark cycle. The use right media mathematics will be able change students' attitudes behaviors more active participating lessons making it easier for students find their own problem solving results. In this case medium used Geogebra help explain material Circle. results study turned geogebra can increase activeness outcomes students. seen from percentage observations all aspects pre-cycle experienced an 32.45% average score replay value initial condition increased 19.65%.
