Do students today know less than their parents or grandparents did as students? Are they being academically outclassed by students of other nations? Or have ideologically driven policy makers painted an unnecessarily negative picture of student achievement? 相似文献

This study analyzes the predictors of 2 types of media selectivity: interest-based (i.e., choice of entertainment over politics) and partisan (i.e., choice of pro-attitudinal over counter-attitudinal or balanced news). Relying on a large survey-based experiment, we find that issue-specific engagement variables, including perceived issue understanding, issue importance, and issue attitude strength, predict interest-based and partisan selectivity above and beyond the influence of general political knowledge, news interest, and strength of political leanings. These results show that the drivers of selectivity are more complex than general political attributes; rather, they are contextual and reflect people’s engagement with particular issues. 相似文献

Scholarly productivity and the research reputation of academic staff frequently dominate as criteria in the review of higher education courses, disciplines and institutions, a bias which represents a profound hazard for plausible evaluation. Three distinct outcome constructs were identified from analyses of performance indicator data gathered on the accounting discipline in Australia. They were the scholarly productivity of the academic staff involved, the quality of teaching and learning as perceived by students and graduates, and the academic efficiency, in terms of subject completion rates, with which the courses were conducted. Each outcome was shown to be related in a different manner to various characteristics of the courses investigated. The results challenge the orthodox view that scholarly productivity will lead naturally to other desired outcomes of higher education, question the usual surface level interpretation of performance indicators, and suggest that evaluation in higher education might combine connoisseur and performance indicator approaches within the framework of a realist epistemology, placing emphasis on the structures and mechanisms which generate the diverse and distinct outcomes of different courses. 相似文献

Florida and Puerto Rico Secondary Science Teachers’ Knowledge and Teaching of Climate Change Science
Benjamin C. Herman Allan Feldman Vanessa Vernaza-Hernandez 《International Journal of Science and Mathematics Education》2017,15(3):451-471
Misconceptions about climate change science are pervasive among the US public. This study investigated the possibility that these misconceptions may be reflective of science teachers’ knowledge and teaching of climate change science. Florida and Puerto Rico secondary science teachers who claim to teach extensively about climate change were surveyed in regard to their conceptions of climate change science and the climate change-related topics they teach. Results show that many teachers hold naïve views about climate change (e.g. that ozone layer depletion is a primary cause of climate change) and climate change science (e.g. that it must be based on controlled experiments for it to be valid). In addition, teachers in both groups neglect crucial topics such as how evidence for climate change is developed and the social, political, and economic dimensions of climate change. Our results suggest the need for teachers to understand how to teach climate change and the nature of climate change science using authentic contexts that promote effective socioscientific decision-making and climate change mitigation. 相似文献

Solving Bernstein's Problem: A Proposal for the Development of Coordinated Movement by Selection 总被引:6,自引:0,他引:6
In recent years, many established concepts in the theory of human motor development have undergone profound change, and our knowledge has increased greatly. Nevertheless, some outstanding problems remain unsolved. A central problem concerns the redundancy of effective movements, first pointed out by N. A. Bernstein. The human motor system is mechanically complex and can make use of large number of degrees of freedom. The controlled operation of such a system requires a reduction of mechanical redundancy, effectively by reducing the number of degrees of freedom. More recent work has shown that this problem is hard to solve explicitly by computing solutions to the equations of motion of the system. Equally challenging to traditional computational approaches is the fact the motor systems show remarkable adaptability and flexibility in the presence of changing biomechanical properties of motor organs during development and when faced with different environmental conditions or tasks. Solutions to these problems would have a large impact on a variety of issues in child development. In this article, we stress the importance of the somatic selection of neuronal groups in maps for the progressive transformation of a primary movement repertoire into a set of motor synergies and adaptive action patterns. We present results from computer simulations of a simple motor system that works according to such selectional principles. This approach suggests a provisional solution to Bernstein's problem and provides new parameters to guide experimental approaches to the development of sensorimotor coordination. 相似文献

The case study was conducted to examine the feasibility of an early intervention curriculum called Responsive Teaching with two five-year-old children from Turkey who had significant developmental delays. This study determined whether Turkish mothers might be successful in learning to become more responsive to their children, and whether this would result in significant improvements in their children’s development. Both dyads received 28 individual parent–child intervention sessions which were conducted over a four-month period of time. Pre-, mid-, and post-assessments indicated improvements in the mothers’ responsiveness to their children and the children’s levels of engagement with their parents. There were also improvements in the children’s language and personal social development. Mothers reported that Responsive Teaching helped them learn to interact more effectively with their children and that this resulted in longer and more enjoyable interactions with them. Results from this investigation are discussed in terms of their implications for providing developmental services to preschool-aged children with disabilities in Turkey. 相似文献

A linear causal model is postulated and path analysis procedures are used to examine the direct, indirect, and total influence of 39 variables (grouped into eight general measures) on the salaries of 24.461 faculty members associated with virtually every discipline and type of postsecondary institution in the academic community. The results show wide variation in the relative influence of characteristics of postsecondary institutions and the personal and professional characteristics of faculty members on faculty salaries. The implications of these findings are discussed and specific guidelines are provided to assist those interested in examining the external and internal consistency of the faculty salary structures of their respective institutions. 相似文献
