An index of student patterns of item response, when aggregated to the class level, was shown to identify classes that have a poor match between test content and instructional coverage. The mean caution index for a class can best be interpreted knowing the within-class standard deviation of the index. (Author/LMO)

Tested the hypothesis that young children's tendency to draw horizontal or vertical objects perpendicularly to an oblique surface reflects their preference for perpendicular drawings as conceptually correct depictions. (Author/RH)

Presents five simulation models reflecting sequential levels of children's simple arithmetic story problem solving skills. Outputs of the models are compared with data obtained by presenting 60 five- to eight-year-olds with change problems to examine models' deterministic nature. Results indicate the models give an adequate description of behavior…

Evaluates estimates of full-value-equalization rates, using a study of 20 New York cities and their school districts to (1) show that these estimates contain significant errors, (2) discuss how these errors affect intergovernmental relations, and (3) analyze how they affect equity in financing local schools. (MCG)

Clues in the answers given to the Spanish Advanced Placement Examination questions can identify the test-taker as having learned the language in the classroom or as a native speaker. The Educational Testing Service has found mechanisms to ensure that the tests are equally suited to the two groups. (MSE)

Concludes that junior high school students encode movies better than prose, but that college students encode both equally well. (FL)

Reviews research on the language learner and immersion-type bilingual education programs. It is noted that formal foreign language teaching may be needed in these programs for primary school children. It is suggested that research is needed and that a combination of functional and formal approaches be used. (Author/AMH)

Discusses the size-weight illusion that occurs when a person lifts two equal-weight objects differing in size and perceives the larger object as lighter than the small object. Describes several inexpensive techniques for demonstrating the size-weight illusion and reviews some relevant issues concerning this phenomena. (MJP)

A survey of 101 faculty in a variety of disciplines found that most do not give much attention to the composition of electronic mail messages and are not bothered much when receiving messages containing mechanical or composition errors. Results suggest faculty should be cautious about relaxing the rules of grammar, punctuation, and good writing in…

A study of 191 juniors and seniors from 6 Oahu high schools tested their ability to interpret and construct search statements after reading brief instructions on concept analysis, Boolean operators, and search statement format. On average, students made two errors per statement; scores and types of errors are examined for influences of gender and…

Presents an analytic foundation of English-as-a-Second-Language pedagogical research and application extending beyond the traditional "superficial" categories of morphosyntactic rule violations and false cognates. The study focuses on lexical-semantics, syntax, text-analysis, and pragmatics, and synthesizes major categories of…

Analysis of Chinese undergraduates' oral production of English lexical items they had already been exposed to found that factors affecting both placement and phonetic stress errors involved native language patterns, syllable structure, and the lexical item's position in the rhythmic sequence.

Presents a selection of solutions of the "Three Hungry Men" problem from grade three to college students with three different strategies used: backward, forward, and forward/backward strategies. Provides error patterns in each strategy. Discusses some implications for teaching of problem solving. (YP)

Discusses self-regulation, learning to learn, and adaptive problem solving, and describes study of third, fifth, and eighth graders. The study investigated whether providing a model of self-regulating skills via teaching a computer to solve problems would increase the number tasks completed, and decrease the error and trial rate. (11 references)…

Describes the unique reliability problems of very large databases that necessitate specialized techniques for hardware problem management. The discussion covers the use of controlled partial redundancy to improve reliability, issues in operating systems and database management systems design, and the impact of disk technology on very large…
