Communication competence for hearing-impaired individuals who use speechreading involves understanding nonverbal cues, making communication needs known, using alternative strategies, and using component skills effectively. Speechreading training should include real-life simulations, situational role-playing, and modeling of difficult situations…

A review of laboratory research estimating effects of mild hearing impairment on infant speech perception abilities, under conditions simulating mild hearing loss in normal hearing infants, suggests that even mild alterations of auditory input during infancy may have significant developmental consequences. Results support identification,…

A multimedia module for training college faculty in discussion-leading techniques consists of a computer-based component, demonstration videotape, and practice session. Use of the module with an initial group of teachers has resulted in increased confidence in discussion skills, rearrangement of participants' classrooms, and positive participant…

Presents a Project WET water education activity. Through a game of tag that simulates the effects of environmental stressors on macroinvertebrate populations, students relate the concept of biodiversity to the health of an ecosystem. (LZ)

This article describes virtual reality (VR) technology and discusses its potential application to the teaching of social skills to children and youth with behavior disorders through the use of interactive role plays. Limitations of the current technology and difficulties inherent in modeling simulations of human behavior are noted, as are…

Microcomputer software that simulates drug-concentration time profiles based on user-assigned pharmacokinetic parameters such as central volume of distribution, elimination rate constant, absorption rate constant, dosing regimens, and compartmental transfer rate constants is described. The software is recommended for use in undergraduate…

This study explored the conflict resolution ability of 30 children with specific language impairment (SLI) and 30 children with normal language (NL) in grades 3 through 7. Children with SLI suggested fewer types of strategies to resolve hypothetical conflicts than their NL peers. The groups did not differ in the number of strategy types used in…

Because of increased aid to developing nations, cross-cultural evaluation has become more common. Whether culture has an influence on evaluation was studied by simulating a study of Mexican and U.S. agricultural administrators. Results demonstrate the effects of cultural differences on evaluation. (SLD)

A proposed model for the validity of measures of professional competence treats validation as the evaluation of inferences drawn from test scores, focusing on evaluation, generalization, and extrapolation. The model is used to indicate strengths and weaknesses of assessments of professional competence: observations of performance, simulations, and…

An interactive videodisc-based simulation was used to train 3 students (ages 12-17) with moderate disabilities on locating and purchasing items in convenience store settings. The students improved in their effectiveness and efficiency of locating items in the simulated environment and showed some transfer of skills to natural environments. (JDD)

Complete medical interviews and physical examinations, performed on simulated patients by a class of interns, were videotaped and scored using a rating scale developed for the purpose. Findings show that the system can be used for feedback to both students and program administration concerning performance quality. (Author/MSE)

The research of the Biology component of the Teacher Assessment Project (BioTAP) of Stanford (California) University is described. BioTAP uses portfolio development as an important aspect of teacher assessment. Advantages and drawbacks of teacher portfolios are discussed, including issues of validity and reliability. (SLD)

Fourteen high-intelligence and 13 low-intelligence first-year college students worked in a structured or unstructured simulation environment to learn correlational principles. Thinking-aloud protocols indicate that high-intelligence subjects exhibit a better working method than do low-intelligence subjects, and that working method is a strong…

Clinical surgery faculty (n=78) evaluated videotaped simulated surgery student oral examinations. Results showed that regardless of the content of students' responses, evaluators were strongly influenced by how well students communicated. Evaluators preferred a moderate response rate and direct eye contact over a slower response rate and indirect…

The principles of magma addition and liquid layering in magma chambers can be demonstrated by dissolving colored crystals. The concepts of density stratification and apparent lack of mixing of miscible liquids is convincingly illustrated with hydrous solutions at room temperature. The behavior of interstitial liquids in "cumulus" piles…
