This paper describes a recent effort to infuse the Total Quality Improvement (TQI) approach, popularized by Deming and others, into an upper-division, junior-senior economics course at the University of Wisconsin-Madison. The process of infusing TQI into instruction has received relatively little attention. Most efforts to bring TQI into higher education focus on improving administrative operations and establishing courses and programs for students to learn how to apply TQI in their future jobs. The challenge is in using TQI to help students realize their potential for learning in traditional courses.The TQI instruction approach developed for use in the course had three major elements. Customer Focus is represented by the proficiencies emphasized in the course and expected of graduating economics majors. Student Involvement is represented by team-centered research projects whose purpose is to enhance the proficiency of creating new knowledge. Continuous Improvement is represented by ongoing student evaluations of the course and instructor, carried out by a student team.After discussing the motivation for adopting this approach and the independent development of the concept of proficiencies in the economics major, the paper moves on to discuss the planning, implementation, and execution of the course. Particular attention is given to discussing the operation of the teams and the development of a multi-faceted ongoing evaluation process to assess the effectiveness of the TQI Instructional Approach.The evaluation results indicate strong student satisfaction with the TQI orientation of the course, while at the same time pointing out ways of improving what was done.The author is grateful to Jacob O. Stampen and Mark Finster for helping him learn about TQI, and to Ian Hau whose seminar stimulated this effort to infuse TQI into the classroom. Helpful comments on a draft of this paper came from Jacob O. Stampen, Maury J. Cotter, Charles A. Liedtke, Paul Weiss, and Michael L. Williamson. Special thanks for generating much of the underlying data go to the Evaluation Team of Kevin Brumm, Kimberly Klatt, and John Kittilstad, and to the Proficiency Team of Evan Anderson, Deana Lynn Grobe, and Tom Yale. Ilona Loser and Kris Feggestad assisted in assembling the results of the surveys. Suzanne Vinmans handled the typing, Vicki Szypulski made the visuals, and Elaine Moran provided helpful editorial suggestions. Laura A. Guy, Data and Program Library Service, facilitated access to the Current Population Survey tape used by several teams, and Kurt Neuwirth, Social Science Microcomputer Laboratory, created a user-friendly approach to the Current Population Survey data.  相似文献

Recent research has shown that many people with dyslexia find it unusually difficult to detect flickering or moving visual stimuli, consistent with impaired processing in the magnocellular visual stream. Nonetheless, it remains controversial to suggest that reduced visual sensitivity of this kind might affect reading. We first show that the accuracy of letter position encoding may depend on input from the magnocellular pathway. We then suggest that when children read, impaired magnocellular function may degrade information about where letters are positioned with respect to each other, leading to reading errors which contain sounds not represented in the printed word. We call these orthographically inconsistent nonsense errors letter errors. In an unselected sample of primary school children, we show that the probability of children making “letter” errors in a single word reading task was best explained by independent contributions from motion detection (magnocellular function) and phonological awareness (assessed by a spoonerism task). This result held even when controlling for chronological age, reading ability, and IQ. Together, these findings suggest that impaired magnocellular visual function, as well as phonological deficits, may affect reading.  相似文献

This article explores the complex process of school change over a six‐year period in one high‐poverty, urban elementary school in a northeastern city of the United States. The school included in this instrumental case study was identified by its State Department of Education as “being in need of improvement” in March 2000. Findings suggest that creating opportunities for context‐based solutions, curricular coherence, and responsive and consistent coaching were the necessary means for leveraging change at this school. Further, responding to the layers and iterations of educational policy, and addressing the deeper social issues intimately associated with serving high‐poverty communities, was essential. We identify policy issues that contributed to the complexity of this school’s improvement efforts. Our analysis extends beyond surface‐level documentation of the school’s inputs and outputs, and illustrates what it means to meet individual students’ needs in complex social and institutional spaces. We also discuss social justice issues that are linked with current policies targeting improved outcomes for all children.  相似文献

Identifying social learning in wild populations is complicated by the relative lack of ability to conduct controlled experiments in natural habitats. Even in more controlled captive settings, tracking the innovation and spread of behavior among known individuals can be challenging, and these studies often suffer from a lack of ecological validity. In recent years, a host of new approaches have been undertaken to attempt to provide more quantitative control and empirical demonstration of social learning, both in the wild and in captive settings that more closely mimic natural contexts. Developmental approaches are being undertaken more regularly that allow us to study the ontogenetic trajectory of complex skills in a variety of taxa. Likewise, a spirited focus on the social context of social learning has emerged, and researchers have begun to meticulously analyze the influences of social systems and the characteristics of demonstrators and observers. Here, we provide a review of these studies and summarize the opportunities and constraints that exist when one attempts to study learning in social species. We suggest that although the study of social learning in nonhuman animals is becoming much more complex, addressing this complexity provides a fruitful model for understanding the evolution of human cultural behavior.  相似文献

This paper discusses trends in contemporary Danish early childhood education and care (ECEC). Data are sourced from various policy documents, along with material from ongoing research projects in which the authors are involved. It is claimed that contemporary policy on Danish day care services has a tendency to emphasize narrow curriculum improvements and standardized testing. The democratic dimensions are still relatively strong, but at the moment these dimensions are interpreted within a skills‐and‐testing framework, which is leading to a situation where the political masquerades as the technical.  相似文献

During the past decades, many developing countries have been severely hit by a combination of poverty and the HIV pandemic. However, there has been a debate about the relative contribution of these two factors. This study showed that poverty and orphanhood were two separate but interrelated factors contributing to poor schooling. There were no differentials shown based on double orphanhood or gender. We recommend that educational policies should put into consideration both poverty and orphanhood in order to increase schooling access for children affected by HIV/AIDS and poverty.  相似文献

Purpose: To evaluate the influence of physical maturity on the changes in ventricular morphology and function with sport training in female youth athletes.

Methods: Thirty-two female athletes (age 13–18 years) underwent height and weight measurement and 2-D echocardiographic evaluation immediately prior to, and following, a 20-week soccer season. Pre- and post-season left ventricular end-diastolic diameter (LVEDD), end-diastolic volume (LVEDV), ejection fraction (LVEF), stroke volume (LVSV), mass (LVM), and posterior wall thickness (LVPWT), right ventricular end-diastolic diameter (RVEDD), end-diastolic area (RVEDA), and fractional area change (RVFAC), and interventricular septal thickness (IVST) were compared. In-season change in each variable was compared across pre-season hours of vigorous physical activity (0–1, 2–3, >3 hours).

Results: Significant increases were identified in LVEDV (51.3?±?10.4?v 56.4?±?9.6?ml/m2, p?=?0.001) and RVEDA (10.5?±?1.9?v 11.3?±?2.5?cm2/m2, p?=?0.040), but not LVEDD, LVM, LVPWT, LVSV, RVEDD, RVEDA, RVFAC, or IVST (p?>?0.05 for all). In-season changes in echocardiographic variables did not differ across hours of pre-season vigorous physical activity (p?>?0.05 for all).

Conclusion: Among female adolescent soccer players, in-season training elicits changes in resting ventricular volume, but not wall thickness or systolic function. These adaptations do not appear to be influenced by pre-season physical activity level.  相似文献
