Abstract:

A convenient and user-friendly method for computer-based L2 question presentation, answer entry, feedback, and revision is presented. This method presents a "pool" of text chunks from which the student forms an answer by using a mouse to select and drag the chunks to form the answer. The chunks may range in size from single letters through syllables, infixes, complete words and phrases.

Several methods of feedback may be selected (including edit markup) and the mechanics of answer revision consist simply of rearranging, adding, and deleting chunks. Spelling and typographical errors are eliminated, and consequently edit markup is clear and unambiguous. Questions can vary in depth and difficulty from the equivalent of simple multiple choice to nearly free-form short answer questions.

This method is particularly appropriate for languages with exotic alphabets (such as Thai) since students will not need to learn to type on an unfamiliar and exotic keyboard, but will also be useful for languages which use roman alphabets. In addition, a "virtual keyboard/keypad" is described, which can be used by lesson authors as an aid in typing question text. A prototype Windows-based program incorporating these features is also described.
