Computers are increasingly a part of preschooler's lives. The purpose of the present paper was to discuss research avenues employing computers as a learning tool and to analyse the results obtained by this method at the preschoolers' learning level. Specifically this research was to determine if computer assisted instruction (CAI) was a useful tool to enhance cognitive, emotional, linguistic, and literacy skills in preschool children. CAI programmes may never replace the book and the blackboard but one should be aware that they were more accessible by young children, who learn better with pictures and sounds, and the proper use of appropriate programmes could make a considerable difference.
