Science curriculum materials designed to improve the attitudes of below average students were developed from guidelines based on a survey of the strengths and weaknesses of these students. (Author)

Ten boys and girls in a nursery class, who were matched in age and in nursery experience, were each observed for a complete school day. All of their responses and activities were categorized and analysed in relation to their social class and intellectual and verbal ability. (Author/RK)

Data for this study were collected from a project funded by the Hogg Foundation. (SB)

Research supported by the U.S. Office of Education.

The adequacy of equipercentile, linear, one-parameter (Rasch), and three-parameter logistic item-response theory procedures for equating 12 forms of five tests of general educational development were compared. Results indicated the equating method adequacy depends on a variety of factors such as test characteristics, equating design, and sample…

A study to determine the applicability of undergraduate education in jobs and to evaluate some of the benefits accruing to a college educated person in the labor force is discussed. The relationship between the usefulness of college training in jobs and levels of job satisfaction and income is examined. (Author/MLW)

The Rasch model was used to equate reading comprehension tests of widely different difficulty for three groups of fifth grade students of widely different ability. Under these extreme circumstances, the Rasch model equating was unsatisfactory. (Author/CTM)

The relationship between types of students and the times students preregistered for the fall semester was investigated. The relationship between ACT scores, sex, approximate high school class size, first semester GPA, and time of registration/orientation at the University of North Dakota was explored. (MLW)

A review of the technical data available on the 1972 norms edition of the Stanford-Binet demonstrates how inadequate these data are. The Stanford-Binet should not continue to be used in important decision making processes unless this weakness is corrected. (Author)

A study of the context effects on item parameters for one- and three-parameter latent trait models showed that: (1) changes in context affected their item difficulties; and (2) context effects were more important in making predictions for single items than for groups of items. (Author/RL)

Responses of an unbiased random sample of students were compared with the responses of a self-selected sample for the evaluations of two medical school courses. When responses were investigated across items, the patterns of differences between the random and voluntary samples appeared to be unique to each class. (Author/MLW)

A device designed for sampling algae in rivers and streams is described. Techniques for observing algae in the laboratory as well as tips for maximizing success in sampling are given. (SA)

It is shown that using formulae for the estimation of sampling errors based on simple random sampling, when a design actually involves cluster sampling, can lead to serious underestimation of error. Jackknife and balanced repeated replication are recommended as techniques for dealing with this problem. (Author/CTM)

Details the procedures followed in obtaining a frequency-of-use list of the most-to-least-used instructional materials in mathematics (K-12), reading (K-6), and science and social studies (each 7-12). (Author/MLF)

Explores the relationship between pupil attainments on British National Curriculum Tests at the end of Key Stage 2, teacher assessments, and several pupil characteristics, such as gender and age) using representative samples drawn from schools in England from 1996-1998. Finds levels of agreement between teacher assessments and test results…
