Connecting Productive Schools And Workplaces For A Knowledge Society, Byrd Jones, Robert Maloy Jun 1994

Connecting Productive Schools And Workplaces For A Knowledge Society, Byrd Jones, Robert Maloy

Robert W. Maloy

As American education struggles to achieve new competencies for an emerging information age, popular reforms remain locked in industrial-era metaphors. Testing for basic skills, teacher professionalism, and school-business collaboration assumes that schooling prepares workers with skills for predictable roles. Meanwhile, computers and related technologies make possible low-cost information that is transforming learning and jobs. Hierarchical organizational structures that subordinated most employees have given way to flatter, flexible teams. Quasi-autonomous decision making by knowledgeable professionals extends to more and more workers. When businesses simply offer schools a few extra resources, they stunt interactive partnerships that enable youth and business cultures to …

Cortical Type 2 Astrocytes Are Not Dye Coupled Nor Do They Express The Major Gap Junction Genes Found In The Central Nervous System, Daniel Belliveau, C. Naus Dec 1993

Cortical Type 2 Astrocytes Are Not Dye Coupled Nor Do They Express The Major Gap Junction Genes Found In The Central Nervous System, Daniel Belliveau, C. Naus

Daniel J. Belliveau

The O‐2A progenitor cell first described from the rat optic nerve is a bipotential precursor of oligodendrocytes and type 2 astrocytes. Each cell expresses specific markers that distinguish them as unique cell types. O‐2A progenitors cultured in high serum preferentially differntiate into type 2 astrocytes and when exposed to defined medium or low serum develop along the oligodendrocyte lineage. We analyzed the gap junction gene expression of type 2 astrocytes to determine if they are coupled to form a syncytium, like their type 1 astrocyte counterparts. Dye coupling experiments demonstrated that cortical type 2 astrocytes are not coupled, while type …

Enhancing Professional Competencies In Graduate Education, John C. Smart, Linda Serra Hagedorn Dec 1993

Enhancing Professional Competencies In Graduate Education, John C. Smart, Linda Serra Hagedorn

Linda Serra Hagedorn

The recent spate of national reports criticizing both undergraduate and graduate education (National Endowment 1984; National Institute 1984; Association of American College 1985) has focused on a number of specific educational deficiencies, including an excessive narrowing a the discipline level, insufficient emphasis on academic research and scholarship, and an overemphasis on encyclopedic knowledge. Such criticisms have generated numerous efforts at program improvements by campus officials (Hawley 1989; Klemm 1988). Unfortunately, a dearth of knowledge about the fundamental educational processes of graduate programs has been a serious constraint on efforts to decide which of the numerous improvements will actually enhance student …

Measurement And Judgment In Curriculum Assessment Systems, Glen Rogers Dec 1993

Measurement And Judgment In Curriculum Assessment Systems, Glen Rogers

Glen Rogers

While educators show increasing interest in performance assessment, many measurement specialists express alarm over implications for increased costs. When we see ourselves as assessment practitioners who are collaboratively working with educators to create integrated assessment systems, however, we must first rethink relationships among our measurement, curriculum development, and institutional assessment goals before we can understand what assessment costs are implied. The quality of the contribution of assessment practitioners depends on their knowing when to pursue measurement, and when instead to facilitate coordinated human judgment.
