Bentler, Peter M.; Woodward, J. Arthur – Evaluation Quarterly, 1978
The Head Start data analyzed by Magidson (1977) were reanalyzed using Joreskog's (1976) LISREL computer program methodology. The hypothesis that the Head Start program produced zero effects on the cognitive abilities of its participants was evaluated by several Chi Square tests. In all cases, the null hypothesis could not be rejected. (Author/CTM)

Magidson, Jay – Evaluation Quarterly, 1978
In a reply to the previous article (TM 503 435), Magidson disparages the arbitrary application of the .05 significance level to these data, responds to several assertions, and provides additional data in support of his original article showing positive effects for Project Head Start. (CTM)

Peer reviewedGoldring, Ellen B.; Presbrey, Laurie S. – Educational Evaluation and Policy Analysis, 1986
A meta analysis of preschool intervention programs is performed to arrive at an overall effect size of such programs. Results indicate that despite the diversities in intervention sites, ages of subjects, lengths of intervention, and curricula models, there is a positive homogeneous effect on the variables.

BATEMAN, C.W. – 1966
A MODEL IS CONSTRUCTED TO DETERMINE THE BEST PROPORTION OF FORMAL AND ON-THE-JOB TRAINING IN MILITARY OCCUPATIONS. SPECIAL CONSIDERATION IS GIVEN TO THE UNIQUE SITUATION OF ENLISTED PERSONNEL'S FIXED LENGTH OF SERVICE, THE SMALL PERCENTAGE OF RE-ENLISTMENT, AND THE NECESSITY OF TRAINING ALL ENLISTEES FOR ASSIGNED OCCUPATIONS. THE MODEL FORMULA…
