Abstract :
This study aims to develop mathematics learning tools in the form of RPP and LKPD using the Connected Mathematics Project (CMP) model with the orientation of student?s mathematical problem solving abilities in the material of Two Variable Linear Equation Systems (SPLDV) in class VIII MTs Dar El Hikmah Pekanbaru which has been tested valid. The development model in this study uses the Plomp model which has three stage, namely the Preliminary Research Phase, the Prototype Phase, the Assessment Phase. The data collection techniques used were observation and interviews. The data collection instrument used was a validation instrument. The data analysis technique used is data validation analysis. The result of the research validation analysis by four validators obtained an average validation every RPP of each validator was 100% for aspect of indicator one as measured by guttman scale and 91,07% for aspect of indicator two to seven as measured by likert scale both of which are very valid criteria, and for the average validation every LKPD of each validator was 91,67% for aspect of indicator one as measured by guttman scale and 85. 98% aspect of indicator two to three as measured by likert scale both of which are very valid criteria. Based on the results of this study it can be concluded that the development of learning tools using the Connected Mathematics Project (CMP) model oriented to the mathematical problem solving abilities of grade VIII students of MTs Dar El Hikmah Pekanbaru has been tested for its validity.
