The sustainability concept of Riau cultures through development of mathematics learning devices based on Riau folklore at elementary schools

Abstract

Abstract This research aimed to develop valid and practical mathematical learning devices. Learning devices were developed with the Realistic Mathematics Education approach (RME) based on Malay folklore of Riau. The method in this research was Research and Development (R & D) using Plomp modification with five phases namely: (1) initial investigation, (2) design, (3) realization or construction, (4) Tests, evaluations and revisions, (5) implementation. Samples in this research were Elementary School Benteng District of Riau Province. Learning tools developed in the form of Planning Learning Implementation Planning (LIP) and Students Activities sheets (SAS). The instruments used were LIP validation sheets, SAS validation sheets, LIP practicality questionnaires (teacher and student responses), SAS practicality questionnaires (teacher and student responses) and questionnaires to assess the implementation of learning. The results of LIP validation acquired value about 83.04% with fairly valid criteria, the practicality analysis result of LIP about 85.29% with very practical criteria, SAS validation result about 83.77% with fairly valid criteria, and SAS practicality analysis result about 84.55% with quite practical criteria. Based on the results of the research it can be concluded that learning devices developed based on Riau Malay folklore have been valid and practical.
