The venture capital market and technological innovation

This paper was stimulated by assertions that technological innovation in the United States by new or small firms is being delayed or altogether stifled by an inadequate supply of capital for such firms. Analysis of available data on the performance and activities of public venture capital sources and information supplied by knowledgeable people in the field provided little support, on strictly economic grounds, for the argument that a major problem exists. The data, however, are extremely thin and inadequate to suport recommendations for major policy changes.     

Local Dependence in an Operational CAT: Diagnosis and Implications

The accuracy of CAT scores can be negatively affected by local dependence if the CAT utilizes parameters that are misspecified due to the presence of local dependence and/or fails to control for local dependence in responses during the administration stage. This article evaluates the existence and effect of local dependence in a test of Mathematics Knowledge. Diagnostic tools were first used to evaluate the existence of local dependence in items that were calibrated under a 3PL model. A simulation study was then used to evaluate the effect of local dependence on the precision of examinee CAT scores when the 3PL model was used for selection and scoring. The diagnostic evaluation showed strong evidence for local dependence. The simulation suggested that local dependence in parameters had a minimal effect on CAT score precision, while local dependence in responses had a substantial effect on score precision, depending on the degree of local dependence present.

Networking for Leadership,Inquiry, and Systemic Thinking: A New Approach to Inquiry-Based Learning

Recent changes in science education standards have mandated a prominent place for inquiry learning in science curricula. However, change from traditional teaching methods to a more inquiry-centered approach is difficult to enact. While research to date demonstrates a number of successful inquiry implementations, it also reveals a slow rate of change along with possible reasons for difficulty in adopting inquiry instructional methods. Further, inquiry reforms have failed in the past. The Networking for Leadership, Inquiry, and Systemic Thinking (NLIST) initiative, sponsored by the Council of State Science Supervisors and NASA, proposes to facilitate inquiry through systemic reform designed to avoid the mistakes of the past and incorporate new knowledge about teaching and learning. Systemic elements targeted for change include a standard conceptualization of science as inquiry, instructional materials, professional development, administrative support and leadership, facilities, community involvement, and technology infrastructure. To date, the initiative has created a detailed definition of inquiry learning and a rubric for evaluating instructional materials against this definition. This paper presents the theoretical and empirical foundations for the NLIST initiative, describes its progress, and outlines future goals.     

The Effect of Cognitive Style on the Preferred Format of Instructional Material

Abstract A total of 90 15‐16‐year‐old female pupils from a single‐sex secondary grammar school did the Cognitive Styles Analysis which assessed their position on the Wholist‐Analytic and Verbal‐Imagery learning style dimensions. They were asked to select their preferred format of a single‐sheet handout on study skills which was offered in three modes: Unstructured‐Verbal, Structured‐Verbal and Structured‐Pictorial. Each mode contained the same information and differed only in format. On the format preference, there was a significant effect of the Verbal‐Imagery dimension (p = 0.002), with the majority of Verbalisers choosing the Structured‐Verbal sheet and the Imagers opting for the Structured‐Pictorial version. There was a smaller effect on the Wholist‐Analytic dimension, where Wholist had a preference for the Structured‐Pictorial and the Analytics for the Structured‐Verbal version (p = 0.056). The findings were discussed in terms of their practical implications for a differentiated approach to instruction.     

Moving Toward Family-Centered Early Care and Education: The Past, the Present, and a Glimpse of the Future

Over the past 4 decades, early care and education programs in the United States have struggled to overcome obstacles to active parent and family participation, especially in the wake of recent welfare reform guidelines requiring parents to work outside the home. This article highlights the vision and activities of four Wisconsin Early Childhood Centers for Excellence, which offer family-centered services along with services to young children. Using various strategies, these programs have empowered parents and strengthened bonds between parents and professionals. Their success suggests that new models based on family-centered goals can improve the overall quality of early care and education for young children.     

THE ROLE OF UNIVERSITIES IN PROMOTING LITERACY

This article offers a critique of the traditional role of the university in relation to the promotion of universal literacy. It describes some of the developments in university Involvement in adult basic education in the United Kingdom and suggests possibilities for the future. K argues that universities must commit themselves to a lifelong learning approach to education. They must support new access routes for adult students and collaborative models of research and practice in developing the field of literacy.
