Effects analysis of CALL (Computer-Assisted Language Learning) for enhancing English vocabulary power.

Abstract

Throughout the decades, various computer assisted learning methods have been developed for computer aided educations (CAE). Computer assisted language learning (CALL) is one of those methods which aim to learn foreign languages. This paper presents the effectiveness of CALL as an educational tool to increase vocabulary power for elementary school students in their English classes. For experimental purpose, students are divided into two groups, CALL based group and traditional learning based group. For the CALL based group, students are divided into two subgroups, Web-based learning tool and CD-ROM titles are provided to student in each subgroup respectively, while only traditional lectures are given to students in comparative group. Performance results shows that CALL based learning is more efficient than traditional learning in achieving vocabulary power and especially, CD-ROM title based learning shows better performance than Web-based learning. This comes from the functional simplicity of CD-ROM title and will be discussed in detail at the analysis part of this paper. Some statistically confirmed hypotheses from this experiment could be useful reference for applying CALL based learning in language learning classes for elementary school students.
