Abstract | Third-graders showing negligible mastery of multiplication combinations were randomly assigned to two groups which practiced different subsets of combinations. Retest results were inconsistent with Siegler's (1988) proposal that item-specific computational practice is necessary to change error patterns and promote mastery. Results suggested that children devise increasingly flexible and accurate estimation strategies and use relational knowledge such as commutativity principle. (EV) |
