The Effect of Visual and Interactive Tools on Students’ Performance in Identifying one-to-one Functions

This paper investigates the effect of using computer applications on students’ capabilities in distinguishing a type of functions. The type of functions is one-to-one and the use of the computer applications was through visual and interactive webbased tools. The students who participated in this study were divided into two groups: control and experimental. The students in the first group were taught to identify one-to-one functions using the traditional, definition-based method. The students in the second group were also taught to identify such functions using the traditional method. However, they had the advantage to use the tools. To measure the effect of using the tools, an achievement test was prepared and given to both of the groups twice: before the beginning of the teaching process and after the end of it. The results of the tests for the students in both groups were compared and the results showed that the students in the experimental group outperformed their counterparts in the control group. This provides evidence that utilizing visual and interactive tools in identifying one-to-one functions improve the learning outcomes
