Abstract

In this study, the aim of this research is to produce a learning device based on a valid CRH cooperative learning model. Learning devices are a means used by students to start the teaching and learning process. The learning tools developed are in the form of a Learning Implementation Plan (RPP) and Student Worksheets (LKPD). The development model used in this research is the Plomp model which is modified into 4 stages, namely: (1) Prelimenary Investigation (initial investigation), (2) Design (design), (3) Reliazation / Construction (realization / construct), (4) Test, Evaluation, and Revision (tests, evaluations, and revisions because at this time it is still in a pandemic atmosphere of Covid-19. The data analysis technique used is descriptive statistical analysis which describes the data that has been collected will be tested for its validity. Validation of learning tools is carried out by 4 validators consisting of 2 mathematics education lecturers at Riau Islamic University and 2 mathematics subject teachers at SMK Taxation Riau. The results of the data obtained from the validation of learning tools from the validators were then analyzed. From the research results obtained the results of the validation of RPP for each aspect assessed at 89 , 5% with very valid validity criteria and the overall RPP results 88.67% with criteria validity is very valid. For the results of the LKPD validation, each aspect was assessed at 85.64% with very valid validity criteria and the overall validation results with a value of 84.98% with validity criteria quite valid. Based on the results of this study, it can be concluded that the development of learning tools based on the CRH type cooperative model in class XI Accounting at the SMK Taxation Riau level which has proven its validity is feasible to be used and tested.
