PEMBELAJARAN MATEMATIKA MENGGUNAKAN LEMBAR KERJA SISWA (LKS) BERBASIS MASALAH

This research was conduct to describe mathematics learning plans using problembased worksheet, mathematics learning implementation using problem-based worksheet, and how was mathematics learning results using problem-based worksheet. This research met the essence of descriptively qualitative research. In this research, students of class VII-B MTs Muhammadiyah 1 Malang and researcher as source of the data, while teacher activites, students activites and study result as the product. Data was taken from teacher and students obsevation during learning process using problem-based worksheet. In addition, student study result. Analysis of activity of teachers and students is seen fromthe scores on the observation sheet and averaged to determine how much liveliness teachers and students during the learning process.
