Daftar Isi:
- This quasi experimental research aimed to know the effectiveness of cooperative learning model of group investigation type viewed by student’s mathematical problem solving skill. The design which was used was posttest only control design with the population was all students of grade eight of Junior High School TMI Roudlotul Qur’an Metro in academic year of 2014/2015. The research samples were students of VIIIC and VIIID class that were determined by purposive random sampling. The data of mathematical problem solving skill were obtained by essay test. Based on the result of data analysis, it was concluded that the implementation of cooperative learning model of group investigation type was effective viewed by student’s mathematical problem solving skill.Penelitian eksperimen semu ini bertujuan untuk mengetahui efektivitas model pembelajaran kooperatif tipe group investigation ditinjau dari kemampuan pemecahan masalah matematis siswa.
