The CoVis Project: Building a Large-Scale Science Education Testbed*

This paper describes the construction and research program of the Learning Through Collaborative Visualization (CoVis) Project, a testbed for exploring science education reform with telecommunications technology. The CoVis testbed is contrasted with other forms of educational research in an “ecology of paradigms,” which argues that testbeds are in fact a new setting for research with different requirements and challenges for the researcher. Two extended examples of telecommunications research are provided as examples of the kind of research that testbeds are well suited to explore. The first example is the evolution of videoconferencing in the CoVis testbed. The second example is the design and development of a networked groupware application called the Collaboratory Notebook.

Temperamental Shyness,Frontal EEG Theta/Beta Ratio,and Social Anxiety in Children

The authors examined how children’s frontal electroencephalogram (EEG) theta/beta ratio—an index of neurocognitive control—changed from baseline to a social stressor, and whether these EEG changes moderated the relation between temperament and anxiety. Children (N = 152; M_age = 7.82 years, 52% male, 81% White) had their EEG recorded during a baseline and speech anticipation condition. Children’s frontal theta/beta ratio decreased from baseline to speech anticipation, and this baseline-to-task change moderated the relation between temperamental shyness and social anxiety. Temperamental shyness was related to higher state and trait social anxiety only among children with large baseline-to-task decreases in theta/beta ratio. Findings are consistent with theoretical models hypothesizing that temperamentally shy children with heightened neurocognitive control may be at greater risk for anxiety.     

Higher education policies in Brazil: 1970–90

Under the authoritarian regime, policies on higher education were mostly produced by the Excutive. First of all, an Educational Reform made up for the rapid expansion of a huge private sector where small teaching institutions prevail and which now absorbs over 60% of Brazilian students. The public sector, in turn, was substantially improved: the number of full time faculty increased and teachers in the federal universities were encouraged to apply for a M.A. or a Ph.D. and to get involved with research activities. Meanwhile, a dual funding system (teaching and research) emerged which was responsible both for the creation of graduate programmes all over the country and for the expansion of a research infrastructure. The civilian government (1985 on) brought policy making out of the bureaucracy and into the Congress. The new Constitution granted the university a degree of autonomy it had never enjoyed before which, however, is still to be regulated by further legislation. Policy initiatives driving at institutional differentiation and at performance assessment have systematically failed to become effective due to resistances within the university itself. Meanwhile financial stringency at a time of recession necessarily leads to reductions in funding, notably for research.     

Afro-Caribbean Immigrant Faculty Experiences in the American Academy: Voices of an Invisible Black Population

Afro-Caribbean immigrants have been an integral part of the history and shaping of the United States since the early 1900s. This current study explores the experiences of five Afro-Caribbean faculty members at traditionally White institutions of higher education. Despite the historical presence and influence of Afro-Caribbean communities and the efforts within education systems to address the needs of Afro-Caribbean constituents, Afro-Caribbean faculty members continue to be rendered indiscernible in higher education and to be frequently and erroneously perceived as African–Americans. The study examines the lived experiences of these individuals in the hegemonic White spaces they occupy at their institutions with both White and Black populations. Through their narratives, issues of stereotyping, microaggression, and isolation are addressed. The participants also offer solutions to address these issues by university administrators, department heads, faculty development professionals, diversity officers, policy makers, and other stakeholders. The voices in this study shed light on an overlooked, misunderstood, and under-researched population within our faculty ranks in the American Academy.     

Technology Knowledge and Use: A Survey of Science Educators

The purpose of this study was to determine the current state of technology use and know-how among members of the Association for the Education of Teachers in Science. A web-based survey site and an e-mail merge invited members to participate in the study. The survey examined the differences between current and desired levels of knowledge about using technology as an instructional tool, to support research, to enhance productivity in classroom applications, and to enhance data collection and analysis. Large mean differences about using technology as an instructional tool were found, including: (1) teaching students at a distance, (2) database applications, and (3) desktop publishing. Small mean differences were found for telecommunications and word processing.
