Four children (ages 1-2) with language delays were evaluated to assess the benefits of a play-based model for providing an accurate analysis of a child's language capabilities. The play-based assessment model provided a broader picture of the children's emerging skills, which was helpful in planning interventions. (Author/CR)

Critically analyzes an article by Jan Klabbers, focusing on methodological, epistemological, and ontological viewpoints. Examines the reasoning process whereby the actor approach model of learning environments is derived from the machine approach model; looks at claims of differentiation between rationalism and historicism, and the distinction…

Describes three models that provide a concrete experience of abstract concepts such as DNA replication, RNA synthesis, and protein synthesis. Explains their hands-on use and notes their advantages for teaching and learning. (JRH)

Reports a study which used the effectiveness criteria contained in the Competing Values Model of Organizational Effectiveness to produce a set of organizational effectiveness self-rating scales for Hong Kong higher educational institutions. Scales were developed using the behaviorally anchored rating scales procedure. Highlights the qualitative…

This study presents a model to explore the design of international virtual graduate programs, grounded in the theory of distance education. Results provide initial evidence suggesting that this new instrument can be useful to assess the quality of educational design in distance education. (Contains 67 references.) (Author/LRW)

Little research exists on the assessment of administrators' performance in higher education. The authors offer an evaluation model for assessing and monitoring the effectiveness of academic deans and directors, using generalizability theory as a basis for developing more accurate assessment procedures.

Speech samples of 79 dysarthric patients were judged for voice quality, articulation, nasality, and prosody as well as overall intelligibility. Application of a multiple regression model found that intelligibility can be expressed as a linear combination of weighted perceptual dimensions with articulation as the strongest contributor to…

Explores the prior knowledge children from Key Stage 2 (7 to 11 years) at one school in England had of rock classification and how they developed a more scientific understanding using strategies shown by research to support understanding. Findings for 60 Year 5 and 6 students show the importance of providing students with a conceptual model and…

The ASSIST evaluation is a unique analysis of the relationships among social context, public-health activity, tobacco use, and…

Introduces a cost-benefit transfer model which considers a performer's perception of need, sensibility, and effort to determine the likelihood of putting to use an idea learned in training. The model predicts use through a mathematical formula: the product of need and sensibility divided by effort. Case evidence of academic physicians are cited in…

Describes the technique and benefits of having physics students practice connecting paper models of electric circuits before attempting to use real ones. (WRM)
