Development of Autograph-Assisted Problem-Based Learning Tools to Improve Students' Mathematical Problem-Solving Ability

Abstract

This study aims to: (1) describe the validity, practicality and effectiveness of problem-based learning tools assisted by Autograph to improve students' problem solving abilities; (2) Describe the improvement of students' mathematical problem solving skills with the help of Autograph by using the developed learning tools. This research is a development research that is used to produce certain products and test the effectiveness of these products. To develop and validate the product, it is combined using the Thiagarajan 4D development model, which consists of four stages of development, namely: define, design, develop, and disseminate. The results showed that: (1) Learning tools based on the Autograph-assisted Problem Based Learning model included valid, practical and effective categories; (2) The problem solving ability of students using problem-based learning tools that were developed increased in terms of the average achievement of students' problem solving abilities, namely in the first experiment of 66.67%, increasing in the second experiment of 86.67%. The increase is also seen from the average N-Gain score of 2.50 which is in the high category.
