ABSTRACT

Agus Suyono. Development of Learning Devices Based on Realistic Mathematics Education to Improve Students^ Mathematical Problem Solving Ability at SMK Negeri 1 Air Putih. Thesis. Medan: Postgraduate Program, State University of Medan, June 2022.
This study aims to analyze: 1) the level of validity of the learning devices developed through the Realistic Mathematical Education, 2) the practicality of the learning devices developed through the Realistic Mathematical Education, 3) the effectiveness of the learning devices developed through the Realistic Mathematical Education, and 4) analyzing the improvement of students^ mathematical problem solving abilities by using learning devices developed through the Realistic Mathematical Education. The products developed are: lesson plans, student activity sheets, and student books. The development of RME-based learning devices was developed using the 4-D Thiagarajan development model with 4 stages, namely define, design, develop, and disseminate. The subjects in this study were students of class X RPL-1 and X RPL-2 at SMK Negeri 1 Air Putih in the academic year 2021/2022. The object of this research is the developed X grade SMK mathematics learning device. From the results of trial I and trial II, it was obtained: 1) The learning device oriented to the realistic mathematics approach developed met the valid criteria, in terms of: a) content, and b) construct, 2) the learning device developed met practical criteria, in terms of: a) assessment of validators, b) interviewing student and teacher responses, c) feasibility of learning devices, 3) learning devices developed that meet the criteria of being effective, in terms of: a) classical learning outcomes, b) student activities, and d) positive student responses and 4) The students^ problem solving ability in the second trial increased in the moderate category.
