The site variability issue for Direct Instruction Follow Through sites is examined from a variety of perspectives--meta-analysis of the Abt Associates' data, norm-referenced comparisons, and a longitudinal look at stability of effects. Much of the seemingly unexplained variability found in both the Abt report and the reports by M. Kennedy and E.…

This paper reports the problems involved in measuring the extent to which the practice in program sites matches model theory formulated in Head Start Planned Variation. The main focus in studying program implementation is the question of internal validity, whether the children in the HSPV programs actually receive the treatment being evaluated.…

The inherent methodological problem in conducting research at multiple sites is how to best derive an overall estimate of program impact across multiple sites, best being the estimate that minimizes the mean square error, that is, the square of the difference between the observed and true values. An empirical example illustrates the use of the…

This paper presents a discussion of issues raised in the evaluation of Project Follow Through reported by Abt Associates. The paper suggests that many of the problems inherent in the design of both the program and the evaluation stem from the underlying assumption that one educational model could be found which would best alleviate the educational…

The Model Secondary School for the Deaf is exploring research areas in which computer-assisted instruction (CAI) plays a major role. Research in the area of learning styles and strategies of deaf adolescents is being aided by CAI data gathering systems. Also under investigation is the use of CAI and visual thinking for deaf adolescents. Curriculum…

The movement toward integration of qualitative and quantitative research methods within the same study has been most evident in social policy research. Four major approaches to integrating can be identified in recent studies. The sequential, the parallel, and the fused models have been rather widely used. The interactive model, developed during…

The pilot project, "A Pedagogy of the Land" (POL), provides an opportunity to ponder the relations between aboriginal community/university knowledges in this case, the relations between an Anishinaape land-based pedagogy and the developing theorizing around formal and informal learning. Traditional aboriginal education is not limited to…
