Bringing Science to Life Through Community-Based Watershed Education   总被引:2,自引:1,他引:1  
Four elements of successful student-scientist partnerships (SSPs) have been identified through experience in a wide variety of educational settings. SSPs should: use an inquiry-based approach to education; be built around authentic, community-based investigations; let students be scientists; and allow scientists to be educators. Each element is discussed and illuminated with examples from case studies of watershed education programs that are based on an interdisciplinary, action-oriented watershed education model developed by the Global Rivers Environmental Education Network (GREEN).  相似文献

The extent of curriculum bias was analyzed using seven standardized and criterionreferenced reading achievement tests. This bias was examined relative to five widely used commercial reading programs at the third-grade level. Results from the analysis indicated that the degree of bias varied widely depending on the specific test and program used for reading instruction. The practical and ethical implications of this bias effect are described in relation to the placement of children into reading programs and identification of students as exceptional.  相似文献

The ways in which societies and institutions institutionalize and practice invention management reflects not only how new ideas are valued, but also imaginaries about the role of science and technology for societal development. Often taking the US Bayh-Dole-Act as a model, many European states have recently implemented changes in how inventions at academic institutions are to be handled to optimize their societal impact. We analyze how these changes have been taken up—and made sense of—in regions with different pre-existing infrastructures, practices and semantics of invention management. For doing so, we build on a comparative analysis of continuities and changes in infrastructures, practices and semantics of invention management in North-Rhine Westphalia (NRW, a former Western state) and Saxony (a former GDR state) to reflect on how academic institutions have been handling inventions along transforming socio-political contexts. Building on document analysis and qualitative interviews with research managers, we discuss ongoing differences in practices of invention management and the semantic framing of the societal value of inventions in NRW and Saxony, and discuss how this can be understood before the background of their ideological, political and economic separation until reunification in 1990. Joining the conceptual perspectives of path dependencies and sociotechnical imaginaries, we argue that two critical incidents in the history of these states (the reunification in 1990 and a legal change in 2002) allowed for wide-ranging institutional alignments, but also allowed path dependencies in practices and semantics of invention management to prevail.  相似文献

This study aimed to determine the effects of the Active Early Learning (AEL) childcare center-based physical activity intervention on early childhood executive function and expressive vocabulary via a randomized controlled trial. Three-hundred-and-fourteen preschool children (134 girls) aged 3–5 years from 15 childcare centers were randomly assigned to the intervention (8 centers; n = 170 children) or control group (7 centers, n = 144 children) in May 2019. Participants were mostly Australian (85%) and from slightly higher areas of socio-economic status than the Australian average. There was an AEL intervention effect on inhibition (β = 0.5, p = .033, d = 0.29) and expressive vocabulary (β = 1.97, p = .001, d = 0.24). Integration of the AEL physical activity intervention into the daily childcare routine was effective in enhancing children's executive function and expressive language development.  相似文献

Alpine ski racing is one of the most popular sports in many countries; nevertheless, selection disadvantages and severe injuries result in high dropout rates. In this review we summarize existing knowledge about the specific challenges associated with selection bias and injuries, and their effects on talent development in ski racing.

The relative age effect (RAE) appears in all age categories of national Austrian and international alpine ski racing. Relatively younger athletes seem to only have a chance for selection if they are early maturing. Talent selection processes should consider both the biological maturity status as well as the relative age; additionally, a competition system based on a rotating cut-off date might contribute to a reduction of RAE. Youth and adolescent ski racers report lower injury rates compared to World Cup athletes. The knee was the most affected body part in relation to traumatic injuries. The most frequently reported overuse injuries were knee pain (youth) and low back pain (adolescent level). Athlete-related modifiable risk factors were core strength, neuromuscular control, leg extension strength and limb asymmetries. Based on these findings, prevention measures should be expanded to contribute to long-term injury prevention. In future research more multi-disciplinary, longitudinal studies should be performed.  相似文献

Courses: This semester-long assignment can be featured in undergraduate or graduate communication courses that include a major writing assignment such as research methods, capstone classes, senior thesis sections, or advanced courses on topics such as interpersonal, intercultural, and interracial communication. This assignment is suitable for face-to-face, online, and blended courses.

Objectives: By completing this assignment, students should be able to (a) outline and draft a full research paper or comprehensive literature review on a course-related topic, (b) tailor their papers to meet the requirements of an editor’s call for papers, (c) peer review and provide constructive feedback on classmates’ scholarly papers, and (d) revise and resubmit their original research papers to a mock journal.  相似文献
