An experiment has been conducted in an attempt to determine if there is a significant difference between the achievements of two matched groups of students each having differential treatment with respect to problem solving as measured by a standard final examination. The Physical Solution method gave unquestionably statistically significant results for the upper one-third of the groups. There was no significant difference in the low group which fact tended to hide a small but significant difference from the whole group.
