When comparing the usefulness of highlighted glosses and unhighlighted links,de Ridder (2000;2002) found that the invisible links enhanced L2 reading,perhaps because of the additionally thoughtful choices that learners needed to make, which is an argument for using vocabulary hypertext programs like WordChamp Wed Reader to provide support to all words in the text. Roby(1999) makes an important point claiming that the design of a computer-assisted environment should encompass learners o gloss for their own benefit, enabling them to annotate electronic hypertext on their own,mark words and automatically compile them into printable lists.This feature of selected online vocabulary management systems including WordChamp is in line with the current emphasis on learner autonomy and cooperative learning.
