Nearly all applications of computer assisted instruction have utilized the conventional keyboard as the input/output device for the computer. This has a limiting effect on which areas of education can be supplemented by computerised techniques. This paper describes applications of computer assisted instruction in handwriting and number conservation using special interactive devices which have been designed for teaching these skills. In addition, it outlines evaluative studies which have demonstrated significant improvements in the skills being taught. The broader implications of this work, especially with respect to how education might best utilize computer technology, are also discussed.
