Presents the Dyadic Interaction Scoring Code (DISC) as a marital observation system designed to be compatible with the Datamyte 900 Data Collector. Its derivation from existing coding systems and its contributions are discussed. Data on marital interaction provide a research example of its usage. (JAC)

Researchers are now attempting to improve techniques for studying stable behavior patterns in family systems over long periods of time, e.g., the marital dyad across several levels of function and dysfunction covering time periods of months to years. One approach to improving this research design is based on the assumptions that longitudinal…

Presents a computer analysis of talk-silence patterns of mixed sex triads related to levels of communication apprehension. Results indicate that high apprehensives talk less, talk less often, and are interrupted less often than low apprehensives. Discusses the implications of computer use in talk-silence behavior research. (JMF)

The design of five experiments comparing usability evaluation methods (UEMs) is examined. Each has had an important influence on human-computer interaction (HCI); however, problems with experimental design raised questions as to the efficacy of various UEMs. To obtain desired outcomes of the experimental method addressing HCI issues, close…

Implications of using pupil-to-pupil discussion with mathematics classrooms are discussed, with different ways in which such discussion might promote mathematical understanding. A framework for instruction includes the learning of the computer language Logo. (MNS)

This study, involving four staff members in an institution for people with mental retardation, found that a computerized system of prompts to improve staff-client interactions produced more positive statements, improved distribution of interaction among clients, and resulted in delivery of more positive reinforcement than a traditional…

Using a modified typewriter interaction analysis system, an observer is able to record specific teacher-pupil behaviors as they interact in an instructional setting and distinguish accurately and comprehensively the cause and effect relationship. The system has the capability to distinguish patterns of behavior between different teachers in such a…
