Abstract
We have long been successful in enhancing reading efficiency by using a CALL software with dynamic chunking display in the actual university language classes. But in the age of cloud computing, we need to develop the software into a web application. So we began to use a web system which displays a movie as well as text and sound simultaneously in chunks. In this paper, we will explain this system and how it has been used in the actual practices in some classes. And then, after such tentative uses, we will overview how it is improved now. Eventually, we come to think what the possibilities and challenges are in this web system.
