The data were collected from 82 seventh graders from two high-performing classes in an urban area in China, through a pre-test, a post-questionnaire, and follow-up interviews. Inspired by this, our study aims to develop, implement, and evaluate an AR-based multi-representational learning environment (MRLE) with three representations of linear functions. Augmented Reality (AR) may affect these teaching and learning difficulties by offering dynamically linked representations. However, many students have difficulty connecting multiple representations of linear functions. Using multiple representations is advocated and emphasized in mathematics and science education. The use of Geometer's Sketchpad in mathematics classroom has positive effect on the students' mathematics achievement and attitude towards the learning of graph of functions also improved. Both groups took the same pre-test.This study indicated that the results ofthe experimental group had a significant mean difference compared to the control group. The control group used only the textbooks. Two instruments were used to gather information on the students' mathematics achievement and attitudes towards learning graph functions.A survey questionnaire was used to gauge students' perception on the usage of Geometer's Sketchpad in the learning of graph functions.In the study, the experimental groups used Geometer's Sketchpad-based worksheets and each student has an access to one computer equipped with the Sketchpad software. This study utilized a quasi-experimental design using intact group of students from two classes in an urban secondary school. ![]() The purpose of this study is to investigate the effect of using the Geometer's Sketchpad software in the teaching and learning of graph functions among Form Six (Grade 12) students in a Malaysian secondary school.
