Technology Feature Brief: Glossary

A screenshot of an article within the CISL reader environment is in the background of this image. An arrow extends from the underlined word “nutrients” in the article to a pop-up box in the foreground of the image. The box has the title “Nutrients,” a definition of the word nutrients, and a captioned image of a group of various food ingredients, including carrots, strawberries, and walnuts.

Glossary and dictionary features provide ways for readers to gain an understanding of unfamiliar words immediately. Readers can access definitions of words directly within the text, eliminating the need for separate support texts.

The Center on Inclusive Software for Learning (CISL) at CAST conducted literature reviews and testing within Clusive, our adaptive and accessible web-based reader designed during the project, to develop Technology Feature Briefs. These briefs are designed for educators, developers, and researchers to find out more about particular features within technology tools, how they’re used, and whether they might be effective in addressing different barriers within a technology environment.
