Presents several examples of models for applying data management computer programs to instruction from point of view of an imaginary student. Commentaries following each example speculate on virtues and possible shortcomings of each approach, with the intention of offering valuable perspectives for improved understanding of effective computer use…

Presents thinking-aloud protocols from secondary pupils solving arithmetic story and geometrical problems and analyzes their protocols by using interpretation models founded on a general problem-solving model. A word problem solving simulation is also used to further explicate processes pupils use to solve mathematical tasks. (Author/MBR)

Sex differences in performance on the Australian Scholastic Aptitude Test (ASAT) were investigated. No significant direct effect of sex on performance was found. Sex differences were found to be the result of females having a higher verbal ability, males studying more mathematics, and males having greater confidence in ASAT success. (LMO)

The Albuquerque Language Teachers Association's strategy for increasing public awareness of and support for second-language education has three components: (1) identifying goals; (2) defining projects; and (3) publicizing projects. (Author/CB)

A multi-level intervention model is proposed to help families respond appropriately to the stress of a handicapped child. The case of a mildly impaired child who was abused by his parents is discussed to illustrate the model's integration of information input, belief and attitude change, skill acquisition, and behavior change. (Author/CB)

Presents a planning model for the automation of operations in a large hospital library and specifically describes the design and implementation of a local area network. Part 1 deals with the evolution of the idea, system planning, and design, and Part 2 addresses installation and implementation issues. (EM)

Examines alternatives to the technical orientation of the Ralph Tyler rationale of curriculum planning. Emphasizes the fact that the language and processes of curriculum planning are embedded in metaphysical, philosophical, and moral concerns. Advocates using religious metaphors in models of curriculum planning and discusses how planners' values…

Describes a survey of 356 adult students enrolled in university-level courses at the Open Learning Institute which was conducted to assess the predictive validity of Tinto's theoretical model of student dropout. It was found that, overall, the Tinto model appears to be a useful framework for such investigations. (Author/LRW)

Criticizes methodology and findings reported in the "Consequences" article, particularly in regard to disparities in characteristics of the samples, validity of the measures, and interpretation of results. (NH)

Discusses ways of teaching students about how to assign R (rectus) and S (sinister) labels to enantiomers by using their hands as models. The chirality of the human hands follows the Cahn-Ingold-Prelog Rules for assigning enantiomers and infers the correct chirality of molecules shown in two-dimensional drawings. (TW)

Provides three descriptions of demonstrations used in various chemistry courses. Includes the use of a simple demonstration model to illustrate principles of chromatography, techniques for using balloons to teach about the behavior of gases, and the use of small concentrations of synthetic polyelectrolytes to induce the flocculation hydrophobic…

The relationship between 13 demographic social variables and the numbers of students placed in four objective and four subjective special education classifications for one school year was examined using 50 states and Washington, DC. None of the objective, but two of the subjective classifications were strongly associated with socioeconomic…

In studies involving matrix sampling on items, it is often the case that there are too few responses per individual to use latent trait item response models. A model is formulated wherein individual level variability appears as independent error within the cells of a cross classification of demographic variables. (JKS)

A decision support application based on the Markov analytic model is described, and its use in the formation of policy concerning reduction in force and work force distribution is illustrated through the comparative modeling of two personnel management policies. (MSE)

Rural background and specialty choice of family medicine are each significant predictors of practice in a nonmetropolitan area. The utilization of the medical school selection process to address the maldistribution problem is examined, and a predictive model is described. (MLW)
