Abstract

The purpose of this study is to produce contextual-based teaching materials on function materials to improve the mathematical problem solving capabilities of students in Grade X of Sma Negeri 1 Rambah. This type of research isresearch & development using Bord and Gall development model. Research instruments in the form of validation sheets, questionnaires of students' responses and tests of mathematical problem solving skills (KPMM). The percentageof rata-average teacher guide teaching material validation results is 81.09% with a very valid category and the percentage of teacher guide teaching materials is 87.01% with a very valid category. The results of the student repon questionnaire on teaching materials amounted to 84.05% with very practical categories and no revisions so that practical teaching materials were used in the learning of mathematical function materials. The results of the teaching materials trial based on the KPMM test of the learners showed that the average score of the experiment class students (89.16) was higher than in the control class (67.97). Based on the level of validity, practicality and effectiveness, the development of contextual-based mathematical teachingmaterials
