The Validity of Realistic Problem Based Learning Model Development of Mathematics Learning in Vocational High School (SMK)

摘要

The aims of this research is to determine the validity aspects of Realistic Problem Based Learning Model or abbreviated as Reaalistic PBL Model for students of SMK grade X1 semester 1 in Padang. Realistic PBL Model is a learning model developed from Problem Based Learning Model and Realistic Mathematics Education Approach (RME Approach). The development stages of the Realistic Model PBL refer to the Plomp Model consisting of (1) the introductory stage, (2) the prototyping stage which includes planning, evaluation and revision, and (3) the product assessment stage. The validity aspect of Realistic PBL Model is investigated at prototyping stage with 6 test subjects consisting of 4 mathematicians and 1 educational technologist and 1 linguist. The results show that PBL Realistic Model which includes syntax/learning steps, social system, reaction principle, support system and instructional impact and supporting tools, along with learning support tools have fulfilled valid criteria.
