Reports the results of research that used descriptor subfiles in the online version of "MLA Bibliography" to quantify literary warrant in the domain of scholarly work about fiction. Topics discussed include domain analysis; the interaction between literary works, scholars, and library classification systems; and further research…

Presents a meta-analysis of research concerning the effectiveness of learner control in tutorial computer-assisted instruction based on a model of control as decision making plus information. Results are discussed which suggest that instructional design in learner control research should be based on model building rather than hypothesis testing.…

This commentary on EC 608 301 points out that devotion to the natural science canon of experimental proof in the area of generality testing requires proof procedures that are difficult, expensive, or impossible, but adopting a different canon of proof will not produce the desired certainty about the accuracy of the answer. (JDD)

Reports on a study that compared the behavior of two types of users (search specialists and subject matter specialists with no search experience) with two types of online information retrieval interfaces, including DIALOG. Highlights include data recording via transaction logs, structured interviews, and focus group discussions; and hypothesis…

Explores optimal foraging theory, derived from evolutionary ecology, for its potential to clarify and operationalize studies of scholarly communication. Metaphorical parallels between subsistence foragers and scholarly information seekers are drawn. Hypotheses to test the models are recommended. The place of ethnographic and bibliometric…

Statistical methods for program evaluation with nonexperimental data are reviewed with emphasis on circumstances in which nonexperimental data are valid. Three solutions are proposed for problems of selection bias, and implications for evaluation design and data collection and analysis are discussed. (SLD)

Presents a theoretical formulation that integrates, within the framework of expectation states theory, theories of the emergence of power-and-prestige orders in status-heterogeneous and homogeneous task-oriented groups. Discusses a model based on this theoretic formulation. Offers a model for predicting participation rates in open interaction…

Clarifies the idea of prediction in science teaching by distinguishing between the two extremes of guessing and making logical deductions. Discusses the use of predictions in testing teachers' and students' explanations. (MDH)

Dismissing research that is not theory driven, hypothesis testing, or generalization producing does injustice to the variety of contributions that qualitative research can make. Studies conducted through qualitative approaches are reviewed to summarize the desirable outcomes that can result. No research model has a monopoly on quality. (SLD)

Describes a study conducted at the Dutch Open University to determine students' actual use of embedded support devices (ESD). Topics addressed include a theoretical background; research hypotheses; the use of student interviews; quantitative and qualitative aspects of ESD use; student characteristics; study success (i.e., final examination…

Describes a study of undergraduates that examined the effects on retention of the screen location of information displayed in computer-assisted instruction (CAI) for Spanish. Three treatment groups are described: (1) text was relevant to graphical information; (2) text was at the upper middle section of the screen; and (3) text was random. (32…

Discusses five common myths about statistical significance testing (SST), the possible erroneous and harmful contributions of SST to educational research, and suggested alternatives to SST for mathematics education research. (Contains 61 references.) (MKR)

Presents two statistical topics and examples of their use in natural resource monitoring. The first topic deals with use of correlated observations in calculations of variance estimates for a regional mean, required sample size determination, and confidence intervals. The second topic concerns the use of Bayesian techniques in hypothesis testing.…

Describes software which was developed to help collaborating pupils test hypotheses. Discusses use of the software by 9-14 year-old pupils in Scotland, comparing their activity with that of similarly aged pupils who worked with otherwise equivalent software which lacked any prompts. (Author/AEF)

Describes a multiple case study that was used to evaluate hypotheses on the critical success factors for online course resources in a Singapore tertiary setting. Discusses educational media; human factors pertaining to instructors; technical competency of students and instructors; mindsets about learning; collaboration; and information technology…
