Predicting the Relative Difficulty of Problem-Solving Exercises in Arithmetic. Final Report.
Jerman, Max E.
The possibility of preparing a set of word problems of a predicted level of difficulty based on six variables (for multiplication, division, recall, conversions, operations, and number of words in the problem statement) and on regression equations developed in previous work was investigated. Four problem sets were used in grades four through six, and four different sets were given in grades seven through nine; a total of 340 students participated. The data indicated that the relative difficulty of the exercises was nearly the same over grade levels. Results showed that the general equation used in previous studies did not yield accurate predictions for the problems, based on a chi-square test. New equations computed for each grade level gave more accurate, though not significant, predictions. (Appendix B, pages 54-65, may be illegible.) (Author/DT)
