Reliability and validity of speech rating scales: Some error effects

Validity and reliability are important criteria in speech rating scale development and use. This investigation explores the effects of certain rater errors, compares a newly devloped scale to a widely used instrument, and suggests the existence of specific factors as crucial elements in evaluation.     

Thinking about University Video Centres in the Netherlands

The introduction and use of forward thinking in modern planning is nowadays no longer merely a fashion but an absolute necessity, be it only to make sure that the skeleton of each new university building is provided with the right holes and channels through which to run the cables that might be needed at a future date for internal and external communications.     

Policy intervention and power shifts: an evaluation of South Africa's education restructuring policies

This paper argues that the South African educational restructuring policy proposals are unlikely to become interventions that help bringing about greater development, equity, participation and redress. The reasons for this are manifold. It is contended that the policy proposals are flawed in their conceptualization of the problems and misjudge the educational context and dynamics on the ground. These interventions favour the interests of the more organized and privileged sections of society and only indirectly address the needs of the excluded and disadvantaged. The policy proposals are also based on problematic assumptions about policy and the policy process, and the relationship between policy and practice. Finally, these proposals do not have an appropriate understanding of the change process and are unable to develop strategies to influence the reform process and empower the disadvantaged to struggle for a fairer, more equitable and effective education and training system.     

Educational ethology and experiments in vacuo: Some implications for research and education 1

Course memories and careful observation in the field are both important if researchers are to come to grips with the problems in the real world of the public schools. We should keep in mind that our goal is the production of causal statements which potentially make some educationally significant difference. Using “experiments in vacuo”; a la Galileo is one way for researchers to keep themselves oriented toward the production of causal statements. “Experiments in vacuo” are also a means to avoid overlooking obvious simplicities or appraising nonevents. The examples given in this article illustrate the operation of causal events operating in chains and in parallel and some pitfalls of not examining, at least hypothetically, such causal chains or of distinguishing between causal events operating in series or in parallel. Avoiding such pitfalls is one way to prevent the pessimistic view that research tells us nothing and education makes no difference.     

GaIN (Georgia Interactive Network for Medical Information) study on health professionals' search requests and continuing education needs

Health sciences librarians are being called upon to be more proactive in their institutions' continuing education efforts. In an effort to identify whether search requests indicated CE needs, a study was conducted by a group of members of GaIN (Georgia Interactive Network for Medical Information). MEDLINE requests from health care professionals for subject specific clinical topics were collected during a six-month period via a standard search request form created for the study. Copies of all completed requests were collected and broad ICD-9 codes assigned to the search topics. Institutional reports were generated for each participating library to share with hospital CE coordinators. They were also compiled for the group as a whole, and reflected the "hottest" topics requested during the study period for physicians and for non-physicians (nurses, allied health, administrators). A survey to hospital librarians and CE educators showed some value in the reports, but greater potential for further collaboration between librarians and CE coordinators.
