Eylon, Bat-Sheva; Reif, F. (1979). Effects of Internal Knowledge Organization on Task Performance. https://eric.ed.gov/?id=ED171804

q3 · i? · causal · r2

Experiment 1 null result: t-tests on the composite scores for all local tasks, which relied only on information about individual detailed steps of the argument, showed no significant differences between the H, S1, and S2 treatments; equivalence was not tested.

"The application of t-tests indicates that these scums do not differ significantly between the different treatments."

• Advance organizers produce a small average learning benefit, larger for high-ability than for low-ability learners — the general claim this finding bears on, with the studies behind it
• Ability moderates the hierarchical-organization advantage: low-ability subjects showed no significant benefit, while medium-ability subjects did — related
• A hierarchical internal knowledge organization facilitates performance on complex recall and problem-solving tasks more than a single-level organization of the same knowledge — related
• A hierarchical organization facilitates tasks only when matched to the task domain: organization A aids deductive tasks and organization B aids historical tasks — related
