GeoGebra Assisted Scaffolding: Strategies to Support Student Geometry Problem Solving Ability

Abstract

Problem-solving activity is an activity that can be used to see students' mathematical abilities. Technology such as computers that are developing rapidly can be an alternative source to assist the learning process. The use of technology in Scaffolding is something that can be considered. Khalil et al (2019) stated that using GeoGebra as a scaffolding tool for solving geometry has a positive influence. In particular, further research must be carried out to reveal how applying GeoGebra-assisted scaffolding can support students' geometric problem-solving abilities. This research is descriptive research with a qualitative approach. The research subjects were students of the Mathematics Education Study Program in the fourth semester, totaling three people with high, medium, and low geometric abilities. The research method consists of three stages: 1) preliminary study, 2) planning, and 3) implementation. The data analysis technique consisted of three stages, namely 1) data reduction, 2) data presentation, and 3) concluding. The results showed that GeoGebra-assisted Scaffolding was given in the form of explaining for moderate subjects and for low-level subjects in the form of explaining and reviewing in the analysis phase and in the form of restructuring in the planning phase. The research results can be used as a reference for teachers who use the Geogebra application to provide scaffolding for solving geometric problems according to students' mathematical abilities. So that the form of geogebra-based scaffolding provided can help improve students' mathematical abilities to the maximum.
