245			_aEffectiveness of computer-based instruction _bAn updated analysis
520			_aA meta-analysis of findings from 254 controlled evaluation studies showed that computer-based instruction (CBI) usually produces positive effects on students. The studies covered learners of all age levels — from kindergarten pupils to adult students. CBI programs raised student examination scores by 0.30 standard deviations in the average study, a moderate but significant effect. Size of effect varied, however, as a function of study feature. Effects were larger in published rather than unpublished studies, in studies in which different teachers taught experimental and control classes, and in studies of short duration. CBI also produced small but positive changes in student attitudes toward teaching and computers, and it reduced substantially the amount of time needed for instruction.
