Third graders' understanding of core political concepts (law, nation-state, government) before and after teaching

A curriculum of about 22 hr distributed over 3 months on some core political notions (law, the main Italian political offices, the state) was implemented in an Italian 3rd-grade class of 23 children. Another class of 20 children formed the comparison group. The workings of the executive system were exemplified by explaining the running of the school (which in Italy is state-run). Children's learning and retention of these notions were tested twice, 1 month and 10 months after the end of the curriculum. At pre-test, before implementation of the curriculum, the majority of the children did not have a concept of the political domain: They did not know of parliament and government, hardly distinguished between the law and other types of rules, and did not know that teachers, policemen, and judges are public servants. At post- and delayed post-test, most of the children in the experimental group had mastered the concepts, performing significantly better than the comparison group. Thus, the development of political understanding appears to be due to the acquisition of relevant domain-specific knowledge rather than the emergence of across-the-board logic ability.
