Student attrition continues to be a significant and costly challenge for higher education institutions across the globe. In Australia, universities cite the importance of addressing student attrition through strategic statements and policy documents, and expend time and resources on the problem. Despite vast expenditures, they have made little impact on student attrition, which continues to negatively impact reputation and revenue. Using a regional Australian university as a case study, this paper analyses a student exit survey to identify the complex and inter-related array of factors that contribute to student attrition. It was found that attrition would be better conceptualised as a wicked problem, which is one that cannot be strategically addressed using traditional approaches to problem-solving. The practical implications of these findings reinforce that current approaches to attrition are likely to fail. Therefore, the wicked nature of the attrition problem needs to be taken into account when developing strategies or policies within higher education.  相似文献

The existence of similarities between the ideas of modern students and those of early scientists have led to suggestions about how the history of science can be used to help students undergo similar transitions to those experienced by early generations of scientists. In this paper attention is focused not only on these similarities but also on some crucial differences between the processes and concepts or conceptual frameworks of these two groups of people. In the light of these similarities and differences some of the implications for producing and using historical material in the science classroom are discussed. Specializations: Physics education, concept development, history and philosophy of science and science teaching.  相似文献

In youth-focused community and citizen (YCCS) youth in classrooms and community-based programs produce data that scientists, resource managers and community members will use. This “nested” data situates learners’ scientific activity within larger datasets, projects, and communities, with consequences for youth agency. To document opportunities for agentive learning with data in YCCS, we report on how youth interact with data across eight school and community-based project sites and how youth talk about their data and work. From analysis of 54 participant interviews, we found that youth perceived the data they produced as being used for: (1) broader scientific work, (2) their own learning, and (3) community endeavors. Nested uses of data were most meaningful when youth interacted with end users, were exposed to the larger datasets to which they contributed, or took action linked to data. Not all youth saw, believed, or valued that data would be used by others. Framing of task and purpose, nature of engagement with community users, data production protocols, and level of emphasis on youth-identified questions may contribute to youth perceptions and can foster or undermine conditions for learner agency. The results shed light on when and how conditions for expansive learning and agency get established.  相似文献

The United Kingdom Artist Teacher Scheme (ATS) commissioned a study of the artistic and pedagogical practices of students on a recently established Artist Teacher Scheme MA (ATS MA). The aims of this study were to: investigate the motives and objectives teachers/educators have for undertaking this ATS MA programme, the impact the programme had on their artistic and pedagogical practices and their pupils’ learning; and make recommendations for future development of ATS MA programmes. Through the analysis of questionnaires it was found that the ATS MA’s strength lies in the development of communities of practice and peer support, artist teachers’ renewed confidence in their extended artistic and pedagogical practices, the professional development of artist teachers, and significant development of the art and design curriculum.  相似文献

ABSTRACT

Cyclists in the Tour de France are endurance specialists. Twin and family studies have shown that approximately 50% of the variance in a number of performance-related phenotypes (whether measured at baseline, i.e., natural talent, or in response to training) including those important to cycling can be explained by genetic variation. Research into the specific genetic variants that are responsible has identified over 200 genes containing common genetic variants involved in the genetic predisposition to physical performance. However, typically these explain only a small portion of the variance, perhaps 1–2% and collectively they rarely explain anything approaching the 50% of the variance identified in the twin and family studies. Thus, there is a gap in our understanding of the relationship between heritability and performance. This gap may be bridged by investigation of rare variants or epigenetic variation or by altering study designs through increased collaborations to pool existing cohorts together. Initial findings from such efforts show promising results. This mini-review will touch on the genetics and epigenetics of sporting performance, how they relate to cyclists in the Tour de France and where best future efforts may be directed as well as discuss some preliminary research findings.  相似文献
