The abstract reports this as a tendency, not a tested difference, from the Physics Film Project's achievement comparisons; no statistic is printed and the hedging is retained.

"There was some tendency for medium ability students to do better in the film course."

Discussion¶

Related Claims¶

• In the Utah Physics Film Project, filmed and regular physics instruction showed no differences in large and small schools, but medium-sized schools favored regular instruction — related
• The Physics Film Project concluded that physics can be taught effectively with the filmed course despite inadequately prepared instructors and ill-equipped laboratories — a broader claim this one bears on
• Ability moderates the hierarchical-organization advantage: low-ability subjects showed no significant benefit, while medium-ability subjects did — related
• More intelligent learners benefited more than less intelligent learners from additional film examples, and supplementary instruction reduced common mistakes on difficult material — related
