This study investigated the adequacy of the Rasch model in equating existing standardized tests with groups of examinees not widely separated in ability. With the exception of one test pair and one grade level, the Rasch model using the anchor test procedure provided a reasonably satisfactory means of equating. (Author/CTM)

Four types of experiences in problem solving are identified, and steps children must learn to do problem solving are presented. (MP)

California Assessment Program's application of matrix sampling and item response curve theory to the scaling and reporting of state assessment data is described. It is designed to express educational outcomes in an efficient and interpretable form that is both immediately informative and suited to analysis over extended periods of time.…

Proposes a two-level decision model to evaluate educational programs by types of learners they generate as well as the utility and cost of the program. Decision rules based on the underlying requirement that each learner reach self-sufficiency are described. (Author/BK)

Cut-off scores from two approaches for setting standards are examined. Standards determined from judgments about groups and from inspection of test content are compared. Results indicate that there was neither consistency nor pattern to cut-off scores set from the two procedures. (Author/RD)

The paper specifies mathematically the demand and supply functions for interacting factor markets to characterize the impact of alternative antipoverty programs. Wage subsidies were found to be the most transfer-efficient, implying that education and training is the most cost-effective means of aiding the low-skilled. (MF)

Two related problems are discussed: developing a methodology which (1) will not require full commitment of a local education agency to new techniques which may be ineffective in local settings and (2) will allow graceful abandonment of a new technology that may be proved ineffective. An example is discussed. (CTM)

Discusses the need for mathematics teaching to be matched to children's understanding rather than to the demands of mathematics. Illustrations are given from the results of testing British children by the Concepts in Secondary Mathematics and Science (CSMS) Project, Chelsea College, University of London. (HM)

Case-based reasoning (CBR) focuses on analogy in the context of solving real-world problems. Its research methodology of computational modeling is aimed at deriving hypotheses about cognition. As a plausible educational model, CBR can help refine education philosophy and practice and contribute to the design of educational software. (SLD)

Estimates the effects of three types of differences in Taiwanese vocational schools on students' achievement: institutional investment, student background, and learning processes. The analysis is based on multilevel modeling. Although some subgroups of the qualitative differences affect students' performance, student background has little effect…

Examined gender differences in 514 children's competence and value beliefs from first through twelfth grade, and the relation of these trends to initial differences in parents' perceptions of children's ability. Found that gender differences in competence and value beliefs related to sports and mathematics. Gender differences in competence beliefs…

Provides a method for estimating precision without examining individual database documents, which requires knowledge of only the query or expressed information need and a set of database parameters constant for all queries. Concepts of historic and expected precision are examined, and applications of precision-document graphs are assessed. (36…

Reports a project that incorporated mathematical modeling into a college course. Reports evaluation of the course in terms of criteria derived from the stated aims: modeling performance, modeling framework, pedagogy assessment, and personal growth. Included are two sample problems. (YP)

Explored are responses of students aged 9 to 13 to linear generalizing problems from both a technical and strategic point of view. The methods commonly used were the same in all age groups and across all three questions, although some students choosing each model varied. (YP)

A theory for the visual and cognitive processing, which accounts for slower naming of pictures than reading of words, is introduced. Two experiments assessed the differences distinguishing word reading and picture naming, using 58 undergraduates. The coding of the mind is neither intrinsically linguistic nor imagistic; it is abstract. (TJH)
