A study of the effects of explicitly teaching a problem‐solving strategy on problem‐solving ability, course average, course success, and student retention is reported. Two classes of microeconomics principles were involved in a quasi‐experiment. The experimental class was explicitly taught the problem‐solving strategy and this strategy was then used to solve microeconomic problems in class. The control class was assigned, solved, and discussed the same problems without being taught the problem‐solving strategy. Multiple regression and analysis of variance show that while teaching problem solving did not significantly affect course average, student success in passing the course or problem solving ability, it did result in significantly higher student retention. Results indicate that teaching problem solving only affects those students with low problem solving abilities who would have dropped out of class, and that teaching this strategy helps them remain in the class and succeed. 相似文献

In this article, a Lamaze Certified Childbirth Educator describes her efforts to change the culture of birth in a community hospital in a small Midwestern town. Her experience highlights the challenges and the frustrations involved in creating change. The authors reflect on ways to enhance the success of change and advocacy strategies. 相似文献

Findings from a national study of community college administrative careers, examining issues of position, gender, and race / ethnicity are reported. Career path data also are compared with an earlier national study, showing that paths to the presidency have changed since 1985. Implications for recruitment into senior positions and leadership diversity are discussed. 相似文献

Although a generally positive effect of acute exercise on cognitive performance has been demonstrated, the specific nature of the relationship between exercise-induced arousal and cognitive performance remains unclear. This study was designed to identify the relationship between exercise-induced arousal and cognitive performance for the central and peripheral components of a response time task at two different levels of task difficulty. Sixteen male participants performed both simple and choice response time tasks at eight different arousal levels (from 20% to 90% heart rate reserve). Performance on the simple and choice response time tasks was examined after fractionating the response time into its central component, premotor time, and peripheral components, motor, and movement time. A priori trend analysis was used to test both linear and quadratic relationships. Results indicated that exercise-induced arousal has a positive influence on the peripheral components of response time tasks; however, it has a limited impact on the central components of these tasks. 相似文献

Abstract Three hundred girls in Georgia ranging from 12 through 18 years of age and enrolled in physical education from the seventh grade through the freshman year in college were given eight motor performance test items to measure running, jumping, throwing, speed, and agility. The study was undertaken to test the hypothesis that girls do not improve in motor performance after the age of 13.5 years, and also to investigate whether significant differences existed in motor skills according to age-grade level. Analysis of variance was used to test the significance of variation on each of the eight test items for the seven age-grade groups. Significance of differences in means for each test for each age-grade group was also calculated. Since ninth-grade girls, with a mean age of 14.4 years, scored highest on two items, tenth-grade girls scored highest on four items, and college girls scored highest on two tests, the hypothesis that girls generally do not evidence improvement in motor skills after the age of 13.5 was rejected. 相似文献

This paper reports on the attempts by some Caribbean science teachers to make links between their students' everyday lives and school science in their planning for teaching. It describes how these teachers drew on their exposure to a university graduate course on science education and culture in seeking to access the background cultural knowledge of their students and to incorporate this knowledge in their plans for teaching science. The paper critically examines the experiences of these teachers and highlights both the rewards and challenges that ensued as these teachers prepared for culturally relevant science teaching 相似文献
