Abstract

This research was aimed to produce students worksheet based on discovery learning was valid and practice with effective towards students mathematical problem solving ability. The research subject was grade VIII Ummu Salamah and VIII Khalid students in SMPIT Permata Bunda (IBS) Bandar Lampung in academic year 2016/2017. The stages of development were research and information collecting, students worksheet prepartion, students worksheet validation, preliminary field testing and main field testing. The data of this research were obtained by observation, interview, questioneirs, and mathematical problem solving ability test. The material and media expert said that of the students worksheet development was valid and practice. The result of main field testing showed that the students mathematical problem solving ability that used students worksheet based on discovery learning more than students mathematical problem solving ability that didnt use students worksheet. The conclusion is the students worksheet based on discovery learning was effective to increase students mathematical problem solving ability.Penelitian dan pengembangan ini bertujuan untuk menghasilkan LKPD berbasis Penemuan Terbimbing yang valid dan praktis serta efektif terhadap kemampuan pemecahan masalah siswa. Subjek penelitian ini adalah siswa kelasVIII Ummu Salamah dan Khalid SMPIT Permata Bunda (IBS) Bandar Lampung Tahun Pelajaran 2016/2017. Tahapan pengembangan ini yaitu studi pendahuluan, penyusunan LKPD, validasi LKPD, uji coba lapangan awal, dan uji lapangan. Data penelitian diperoleh melalui observasi, wawancara, angket, dan tes pemecahan masalah. Hasil uji ahli media dan materi diperoleh bahwa LKPD valid dan praktis. Hasil uji lapangan menunjukkan bahwa kemampuan pemecahan masalah matematis siswa yang menggunakan LKPD berbasis Penemuan Terbimbing lebih tinggi daripada kemampuan pemecahan masalah siswa yang tidak menggunakan LKPD berbasis penemuan terbimbing. Simpulan penelitian ini bahwa LKPD berbasis penemuan terbimbing efektif untuk meningkatkan kemampuan pemecahan masalah matematis siswa.Kata kunci :pemecahan masalah, LKPD, penemuan terbimbing.
