q3 i? Across LC selections, subjects chose low-density materials more often than high-density, with overall means of 3.5 selections for print and 3.0 for CBI out of five lessons. → Ross 1988

q3 · i? · causal · r2

ANOVA on the number of low-density selections (out of 5) made by LC subjects found no significant effects of LC strategy or presentation mode. The discussion reports subjects chose low-density versions "on approximately 65 percent of the LC selections."

"Overall means were 3.5 for print and 3.0 for CBI. Thus, there was a general tendency by subjects to prefer low-density materials, regardless of presentation mode."

Related Claims¶

• High-density text takes longer to complete than low-density text in self-paced lessons
• Reading comprehension strongly predicts achievement from high-density microtext, unlike other density conditions
• Low-density text is as effective as high-density text for achievement in expository CBI and print lessons
• Less skilled readers are more likely to select high-density text under learner control
• CBI subjects outperform print subjects on the delayed posttest only — related
