Device and method for optimal reading vocabulary development

摘要

An educational device (10) for facilitating vocabulary development includes a display (11) for displaying reading text, a keyboard (12) and microprocessor (14). The reader selects target words or short phrases whose meaning may be unfamiliar. A context-sensitive sentence illustrating the meaning of the selected portion of the reading text and including the target word or phrase is provided and displayed for a first preselected period. The target word or phrase in the context- sensitive sentence is replaced with verification text and displayed for a second preselected period. A test function furnishes context-sensitive questions that check the reader's understanding of the correct meaning. Performance information is collected and presented upon request.
