Abstract

The purpose of this research is to produce devices of Mathematics learning were valid device in the form of Learning Implementation Plans and Student Worksheets with the Discovery Learning on Cube and Block material Junior High School. The development of learning devices in this study uses development or R&D methods using the Plomp model, namely: 1) initial investigation, 2) design, 3) construction and 4) tests, revision and evaluations. Research data collection instruments were RPP validation sheets and LKPD validation sheets. Data collection techniques used were validation data from 2 FKIP UIR Mathematics Education Lecturers and 2 mathematics teacher at SMP Negeri 36 Pekanbaru. Based on data analysis from the result of device validation, it can be concluded that learning device in the form of RPP is very valid with an average percentage 89,13% and the learning device in the form of LKPD is also very valid with an average percentage 90,83%. So that from this research obtained mathematics learning were valid device with discovery learning model on cube and block material in Junior High School.
