We report a systematic investigation into the relationship between proportional logic and typical Piagetian formal schemata (control of variables, and proportions) for a group of students in the informatics department of a university. The analysis of results suggests that a unitary structure exists in the mastery of hypothesis testing logic, standard proportional logic and formal schemata.

In this study, the mastery of the hypothesis testing (HT) skill and its relationship with the control‐of‐variables (CV) formal schema are investigated. A paper‐and‐pencil test, consisting of 4 items on the CV and 2 items on the ht, was administered to a sample of 144 high school students (from grades 9 to 13) majoring in science in a region in southern Italy. Students of this sample experienced more difficulties in ht logic than in the CV formal schema. The detailed analysis of the answers given...
