age about 30 percent, as seen <strong>in</strong> <strong>the</strong> table below. The reduction <strong>in</strong> overhead<br />

expenses averages 20–30 percent. 10 Research has shown that <strong>the</strong> cost ratios<br />

(calculated as <strong>the</strong> ratio of experimental <strong>in</strong>tervention costs over <strong>the</strong> costs of a<br />

control group) for <strong>in</strong>teractive multimedia technology (computer-based <strong>in</strong>struction<br />

with enhanced audio, graphics, and/or video; CD-ROM and DVD-based<br />

<strong>in</strong>struction; <strong>in</strong>teractive video, etc.) favor it over conventional <strong>in</strong>struction along<br />

with time sav<strong>in</strong>gs of about 31 percent. 11 Simulation of such systems as helicopters,<br />

tanks, and command-control systems for tra<strong>in</strong><strong>in</strong>g combat skills has<br />

also proven to be cost-effective. 12 The operational costs for simulation are, on<br />

average, 10 percent of <strong>the</strong> costs of us<strong>in</strong>g <strong>the</strong> actual systems to tra<strong>in</strong>. 13<br />

Meta-analysis Demonstrates <strong>the</strong> Effectiveness of Instructional<br />

Technology<br />

Researchers often use a meta-analytic approach to review and syn<strong>the</strong>size<br />

quantitative research studies on a variety of issues, <strong>in</strong>clud<strong>in</strong>g <strong>in</strong>structional<br />

that can be replicated. Next, a quantitative measure, “effect size,” is used to<br />
