Aptitude-Treatment Interaction Effects of Variations in Direct Instruction.

Janicki, Terence C.; Peterson, Penelope L.

American Educational Research Journal, v18 n1 p63-82 Spr 1981

Two teachers each taught a 2-week fractions unit to two classes of grades 4-5 students. Each teacher taught one class using direct instruction and the other using a small-group variation of direct instruction. Regression analysis on achievement showed significant aptitude-treatment interaction (ATI) and significant teacher effects. (Author/RL)
