Computers are increasingly a part of preschoolerÕs 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 preschoolersÕ 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.
The present study was designed to investigate the influence of two different types of modeling and knowledge of performance on acquisition and retention of two volleyball skills (set and serve). Participants were 63 boys and 53 girls in elementary school, whose mean age was 11.7 yr. (SD=.5). The children were randomly assigned into two groups given the same practice method for 16 practice sessions (8 for the set and 8 for the serve) but different types of modeling. Some participants observed a videotape of an expert model performing the skills, and the second group observed a videotaped replay of their own performance. Verbal cues were provided simultaneously with the videotaped demonstration. The first group improved set and serve skills more on acquisition and on the retention test than the second group. This improvement was present when scores and form were evaluated. Modeling plus instructional cues seemed to improve children's learning of two volleyball skills (set and serve), and this procedure is suggested for use by practitioners.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
