We can only note correlations among variables, and construct logical arguments about reasonable causal connections. I have not restricted this paper to such aNrigid constraint", from which it would be very difficxilt to generate any Inplications. Participation norms and skills, attitudes and knowledge are taught in these settings through peer and adult modelling, imposition of rules and, t;hrough4pert instruction. It is noted that this conception of political education differs somewhat from that of Patrickwho xfaaradterizes political socialization as a subsfet of political education.
