This res research with the method used is ADDIE. The subj eighth grade students of SMP Negeri 1 Ngaban instruments used were validation sheets, observa learning outcomes tests. The result indicates mathematical module has been developed in the variable linear equations of class VIII SMP student and effective. Based on the results of the validity tes problem-based mathematical module produced is v of 79.11. The implementation observation results based mathematics module is in the practical catego of 82.18. Then the results of student learning tests value of the learning outcomes test was 83.00 and problem-based mathematics module was 87.50% an category. When viewed from the results of th development of problem-based mathematical module the two-variable linear equation system has been su is suitable for use in Ngabang 1 State Middle School di pelajaran yang ajari dikarenakan gunakan untuk an berpikir yang an masalah dalam Oleh karena itu matematika sudah d pendidikan sekolah siswa paling mend Myklebust dalam menyatakan bahwa bekal bagi peserta logis, analitis, sistema Selain itu, Heruman P ISSN : 2339-2444 ndex.php/JPMat/index ASALAH PADA RIABEL limantan Barat ail.com 2 thematical module in the f class VIII SMP students search is a development bject of this study was the ng, Landak District.
