Process Models for Predicting the Difficulty of Multiplication Problems Using Flow Charts. (Part 1 of 2 Parts). Technical Report No. 337.
Romberg, Thomas A.; Glove, Richard
The purpose of this study was to determine whether a process model could be constructed using steps identified from flow charts which accounted for somewhat more variance in predicting the difficulty of two-digit multiplication problems than did a process model developed by Cromer. Cromer's data and variables were used as a starting point. Ten new variables were identified from multiplication and addition flow charts. Seven basic models, 4 reduced models, 10 factor models, 24 one-variable models, and a set of systematic restricted models were examined. Multiple regression analysis was used to predict difficulty. The overall results indicate that the flow chart variables do produce somewhat better models. This volume presents the first of two parts of this report and includes the problem statement and results. (Author/SD)
