Abstract

This study aims to determine: (1) Describe the validity, practicality, and effectiveness of teaching materials based on problem-based learning that has been developed towards improving the mathematical problem solving abilities of grade VIII students of Junior High School Muhamadiyah 07 Medan; (2) Describe the improvement of students' mathematical problem solving abilities by using teaching materials based on the developed problem-based learning. Researchers developed teaching materials in the form of lesson plans, LKPD, teacher handbooks and student handbooks using the Dick & Carey development model. The results showed that: (1) Teaching materials based on problem-based learning in improving students' mathematical problem solving abilities developed had met the criteria of being valid, practical, and effective; (2) Improved mathematical problem solving abilities using teaching materials based on problem-based learning that have been developed seen from the average N-gain value in the first trial and second trial, respectively 0.43 and 0.56 which are in the category moderate. Keywords: Teaching material development, Problem Based Learning, Problem Solving Ability DOI: 10.7176/JEP/12-16-06 Publication date: June 30 th 2021

Highlights

Education is a process that takes place continuously until students reach adult personalities
2.4 Data analysis The teaching material development model that will be carried out is the Dick & Carey development model which consists of 10 stages, namely for several reasons, namely: the Dick & Carey model has been widely used to develop effective tools, every step of the Dick & Carey model there is feedback or revision. , the steps of the Dick & Carey model are very concise, concise, clear and interconnected with one another and in accordance with the applicable curriculum because it begins with identifying learning objectives
Problem Based Learning, the thinking ability of students is really optimized through a systematic group work process, so that students can empower, hone, test, and develop their thinking skills on an ongoing basis

Summary

Introduction

Education is a process that takes place continuously until students reach adult personalities. If students have reached an adult personality, students are fully capable of acting on their own for the welfare of their lives and the surrounding community (Hamalik, 2009: 3) [1]. This can be seen from the phenomenon of society where the educational character of a child who has education is less clear than a child who is sufficiently educated. Intellectual thinking is usually driven from problems related to everyday real life. In such a way, mathematics is referred to as human life and a means to train thinking. It turns out that it is that, Eviliasani, Hendriana and Sanjayawati (2018: 334) [3] that mathematics is taught basically aims at students' mindset so that they can solve problems and are creative, critical, logical, analytical, systematic, and have the ability to work together
