CALL+E-Learning

CALL, which is initially from Computer-assisted language learning, is a concept that teaching or learning can be assisted with computer-based tools. It is a student-centered learning material. Students can do self-studies such as reviewing after school or in class learning. Early CALL programs typically reffers to simple activities such as filling in gapped texts, matching sentence halves and doing multiple-choice activities. There are many kinds of tools can be used in CALL, I will indroduce some of them in this article.

1. A CD-ROM is initially from 'Compact Disc Read-Only Memory', it looks exactly like an audio CD but includes multimedia files that are programmed to use text, images, audio and video to provide interactivity. CD-ROMs are mainly designed for learners to work on alone as follow-up to a lesson, either in a school self-access center or at home. It provides a lot of activities such as grammar practice, and listening and reading materials. However, it has less effective for speaking practice for it is lack of 'real' interaction inherent in a CD-ROM. 2. DVDs are similar to CD-ROMs that a variety of data can be stored on them, but they have much greater storage capacity than CD-ROMs. A character of DVDs is that they allow the viewer to choose from various language options such as pronunciation languages options and subtitle languages options. Therefore, there are several ways that subtitles in DVDs can be used with learners in an English class.

Above all are just some typical examples of Computer-assisted language learning, and there are still a lot of computer-based materials can be used in teaching.
