Responses of Massachusetts groups of 200 male and 200 female delinquents to the items of the School Interest Inventory were contrasted with 200 male and 200 female nondelinquents. The same procedure was followed with an identical number of subjects in Rhode Island. Items which appeared significant at the .20 level in at least one subgroup of 100…

The authors attempt to locate predictor variables associated with the outcome of alcoholic treatment programs. Muscia's study focuses on the predictive potential of: (1) response to a GSR conditioning procedure; (2) several personality variables; and (3) age and IQ measures. Nine variables, reflecting diverse perspectives, were selected as a basis…

Predictions and forecasts are the most critical features of rational planning as well as the most vulnerable to inaccuracy. Because plans are only as good as their forecasts, current planning procedures could be improved by greater forecasting accuracy. Economic factors explain and predict more than any other set of factors, making economic…

Weighting test scores by appropriateness of confidence, has almost without exception raised the reliability of test scores. Greater gains appear to occur for the less reliable tests, but that is at least partly because the more reliable a test is to begin with, the more difficult it is to improve it. If confidence-testing allows us to weight…

The 2-year study evaluated the language performance of 69 hearing impaired, preschool children born following the rubella epidemic of the early 1960's in order to develop an instrument for objectively assessing language achievement and a predictive index of language achievement. Two language rating scales were developed which were tied to the…

Sixty-two first graders identified as being at risk for later learning difficulties were assigned to either of two special classes or distributed through regular first grade classes and were provided with one of the following forms of treatment: direct teaching of reading, indirect teaching (perceptual-motor training), combined treatment, and…

Academic achievement in males is quite consistently predictable from locus of control scores, although this is not true for females. Reasons suggested for this apparent inconsistency include the use of externality as a shield against failure, the instruments used and a "fear of success" in women. Several studies with college and elementary school…

A basically tutorial point of view is taken in this general discussion. The author examines the basic concepts and principles of simulation and modelling and the application of digital computers to these tasks. Examples of existing simulations, a discussion of the applicability and feasibility of simulation studies, a review of simulation…

This paper reports the results of a major research effort by the Northern California Cooperative Research Group (Nor Cal) and the Coordinating Council for Higher Education (CCHE) in California to study junior college attrition. This study differs from the original Nor Cal attrition study in that it was designed to follow up those students who…

Nor Cal Phase III was the experimental portion of the 3-year attrition study. The general purpose of the study was to design and test treatments aimed at reducing attrition among first-time freshmen entering community colleges. Twenty-eight colleges (22 in Northern California, five in Southern California and one out-of-state) were involved in…

Training programs for data processing personnel are plagued by the rapid turnover of the technology involved. An attempt was made to provide a self-paced training plan for a large, data processing staff. Factor analyses of questionnaires about the skills and tasks involved divided the population into specialization groups. Within the…

The purpose of this study was to identify some of the variables that relate to high achievement in elementary school science in Detroit (Michigan) Public Schools. A random sample of 2,112 sixth-grade students from 27 schools was selected for participation in the study. Student data were obtained from the STEP, the Iowa Tests of Basic Skills, and…

Investigated was the relationship between Science Concept Retention by high school science students six months after completion of a course in BSCS biology, CHEMS chemistry, and PSSC physics with each of the following variables: I.Q., Sex, Science Achievement, Natural Science Development, Reading Comprehension, Quantitative Thinking, Delay…

In an effort to predict the academic performance of their students, the counseling staff at Montgomery College (Maryland) administered the Brown and Holtzman Survey of Study Habits and Attitudes (SSHA) to 210 freshmen students. The findings of the SSHA indicate that the majority of entering freshmen at Montgomery College do not know efficient…

This study sought to identify factors that motivate girls to complete a four-year sequence of academic mathematics. Forty variables involving community, family, school and personal factors were measured and analyzed by a MANOVA for correlations with two criterion variables. The first criterion was a classification of schools on the basis of the…
