There were two major objectives to this feasibility study: to explore the range of possible effects of Project Follow Through on parents and on teachers, and to review various models of investigating the nature of these effects. Comparatively little previous research has involved effects on parents and teachers although the original legislation was designed to guarantee parent involvement; but anecdotal data suggest the effects on parents have sometimes been dramatic. Two general models are considered: the rationalized research approach, and a study of the records of political and policy-relevant behavior of parents and teachers. Research methodologies have included surveys, classroom observations, the use of unobtrusvie measures, and field studies. These approaches are considered with respect to their generalizability, comparability, validity, reliability, cost and policy relevance. Finally, the political behavior approach is discussed and recommended because it views individuals holistically, emphasizes utility and policy relevance, and appears to be cost-effective. An Appendix provides information about the results of three previous field studies. (CTM)
