Efficiency of Dynamic Computer Environment in Learning Absolute Value Equation

Abstract

The presented study analyzes the usage of the didactic efficiency of multiple representations in a computer environment in learning absolute value functions and equations. It is known that the axis of symmetry of the graph of the absolute value function is the y-axis. The research was applied at the University of Novi Sad, Serbia. The data were collected by testing a group of 226 students: major chemistry and physics students at the beginning of their common calculus course. The students worked individually in two groups: the experimental and control group. The experimental group of students practiced using GeoGebra software, and the control group of students practiced using paper and pencil. At the end of the experiment, which lasted for two weeks (six school classes), both groups were tested with a post-test of knowledge without using a computer. It can be concluded that GeoGebra software had a positive influence on the students’ achievements in solving absolute value equations.

Learning the Concept of Absolute Value with Multi Representations Approach-Based Instructional Video

“…As a consequence, numerous studies have been conducted to help students understand the concept of absolute value. One method is to employ a learning strategy and/or learning media, such as using GeoGebra [11]. The identified learning media can visually present mathematical concepts.…”
