Rittle-Johnson, Bethany; Star, Jon R.; Durkin, Kelley – Journal of Educational Psychology, 2009
Comparing multiple examples typically supports learning and transfer in laboratory studies and is considered a key feature of high-quality mathematics instruction. This experimental study investigated the importance of prior knowledge in learning from comparison. Seventh- and 8th-grade students (N = 236) learned to solve equations by comparing…

Rittle-Johnson, Bethany; Star, Jon R. – Journal of Educational Psychology, 2009
Researchers in both cognitive science and mathematics education emphasize the importance of comparison for learning and transfer. However, surprisingly little is known about the advantages and disadvantages of what types of things are being compared. In this experimental study, 162 seventh- and eighth-grade students learned to solve equations (a)…
