Propositional logic in informatics students: an experimental study of its relationship with control of variables and proportion schemata

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...
