The usefulness of joint and conditional maximum-likelihood is considered for the Rasch model under realistic testing conditions in which the number of examinees is very large and the number is items is relatively large. Conditions for consistency and asymptotic normality are explored, effects of model error are investigated, measures of prediction…

Criteria for prediction of multinomial responses are examined in terms of estimation bias. Logarithmic penalty and least squares are quite similar in behavior but quite different from maximum probability. The differences ultimately reflect deficiencies in the behavior of the criterion of maximum probability.

Four school districts in the United States provide information about their teacher supply and demand situations for 1974-1975 and project what their situations might be in 1975-1976. Generalizations about the total job market from these four examples only should be made with caution. (Author/PC)

In predicting why one person may label behavior "sexual harassment" while others may be less inclined to interpret communication as harassing, four variables appear: the immediacy of the communication, employment in a field dominated by or balanced with members of the opposite sex, information about anti-harassment guidelines, and prior…

The study compared the self-concepts of siblings of handicapped children with norms and examined mediators for this personality variable. Thirty-four siblings of handicapped children (2-15 years old) from the United States and Canada completed a children's self-concept scale while their parents filled out two questionnaires: one on parental…

Intended to provide insight into the dynamics of demand analysis, this paper presents an eight-step method for forecasting sales. Focusing on sales levels that must be achieved to enjoy targeted profits in favor of the usual approach of emphasizing how much will be sold within a given period, a sample situation is provided to illustrate this…

Students tend to rate teachers in the direction of their grade but not necessarily because of it. (Editor)

Discusses the problems of grading, including the estimation by students of their own performance level. (Editor/PG)

Data from a study of teacher-bias and teacher-expectancy effects on elementary school students' achievement test performance are presented. Analysis of the data revealed that the teacher-bias manipulation had no effect and that the teacher-expectancy manipulation was strongly related to test performance. (Author/RC)

Results of an investigation to determine if differential study habits between internal and external individuals could be a significant factor in the link between locus of control and academic achievement indicate that the study habits are an important factor. (Author/KM)
