摘要：Tujuan penelitian ini untuk mengetahui tingkat ketuntasan hasil kemampuan pemecahan masalah peserta didik yang dikenai pembelajaran MMP,mengetahui tingkat ketuntasan hasil kemampuan pemecahan masalah peserta didik yang dikenai pembelajaran STAD,mengetahui hasil kemampuan pemecahan masalah peserta didik yang dikenai pembelajaran MMP dibandingkan STAD,mengetahui persentase ketuntasan belajar peserta didik yang dikenai pembelajaran MMP dibandingkan STAD,mengetahui pencapaian tingkat berpikir geometri peserta didik menurut Van Hiele. Populasi dalam penelitian ini adalah peserta didik kelas VII SMPN 4 Semarang tahun pelajaran 2012/2013. Teknik sampel dalam penelitian ini adalah cluster random sampling. Penelitian ini menggunakan desain posttest only control design. Hasil penelitian menunjukkan bahwa: (1) hasil kemampuan pemecahan masalah peserta didik yang dikenai pembelajaran MMP maupun STAD dapat mencapai ketuntasan belajar; (2) rata-rata hasil kemampuan pemecahan masalah peserta didik dengan model MMP lebih dari STAD; (3) persentase ketuntasan belajar peserta didik yang diajar dengan model pembelajaran MMP lebih dari STAD. Berdasarkan hasil penelitian (2) dan (3) tersebut disimpulkan bahwa model pembelajaran MMP efektif pada kemampuan pemecahan masalah. Dari hasil penelitian didapatkan pula bahwa peserta didik dapat mencapai tahap berpikir geometri Van Hiele tingkat deduksi informal.
其他摘要：The purposes of this study were knowing the level of completeness results of problem solving abilities of students who are learning MMP,knowing the level of completeness results of problem solving abilities of students who are learning STAD,knowing the results of problem solving abilities of students who are learning MMP compared STAD,knowing the percentage of mastery learning learners who are learning MMP compared STAD,and knowing the level of achievement of students on think geometry according to Van Hiele's theory. Population of this study were students grade VII SMPN4 Semarang academic year 2012/2013. The sampling technique in this study is cluster random sampling. This study used posttest only control design. The results showed that: (1) the results of problem solving abilities of students who are learning MMP and STAD MMP could achieve mastery learning,(2) the average results of students problem solving abilities using MMP learning was higher than the average results of students problem solving abilities using STAD learning,(3) the percentage of mastery learning of students who are taught by MMP learning was higher than the percentage of mastery learning of students who are taught by STAD learning. Based on these results of the study (2) and (3) it was concluded that the MMP model also effective on learning in problem solving abilities. From the results,also the students could reach the informal deduction level of the Van Hiele's level of thinking in geometry.
