Analysis of postural stability in collegiate soccer players before and after an acute bout of heading multiple soccer balls     

Mangus BC  Wallmann HW  Ledford M 《Sports biomechanics / International Society of Biomechanics in Sports》2004,3(2):209-220

The aim of our study was to determine if any immediate changes in balance were discernable in college soccer players after a specially designed heading session. Eight male and two female skilled collegiate soccer players had a baseline balance pre-test using the Balance Master, followed by heading 20 balls kicked consecutively by a teammate from the touchline to a point near the goal, which was followed by a post-test using the same testing technique. Paired t-tests were used to compare balance ability between pre- and post-test conditions. There was no difference in balance pre- to post-test (85.3% and 86.2% respectively). No significant difference was noted from pre- to post-test in the mean equilibrium scores for conditions three through six on the Sensory Organization Test, with the exception of condition four, which revealed a significant increase from pre- to post-test. We concluded that an acute session of heading soccer balls may not result in balance changes in collegiate soccer players.  相似文献

Education on the appalachian trail: What 2,000 miles can teach us about learning     

Karen D. Arnold 《About Campus》2007,12(5):2-9

Rather than dwelling on why too many men don't succeed in college, trekker Karen Arnold examines the features of an experience in which many men do excel: the long hike from Georgia to Maine. Educators can learn why accomplishing this feat may be more rewarding than college.  相似文献   

Breaking the Cycle: Future Faculty Begin Teaching with Learner-Centered Strategies after Professional Development

The availability of reliable evidence for teaching practices after professional development is limited across science, technology, engineering, and mathematics disciplines, making the identification of professional development “best practices” and effective models for change difficult. We aimed to determine the extent to which postdoctoral fellows (i.e., future biology faculty) believed in and implemented evidence-based pedagogies after completion of a 2-yr professional development program, Faculty Institutes for Reforming Science Teaching (FIRST IV). Postdocs (PDs) attended a 2-yr training program during which they completed self-report assessments of their beliefs about teaching and gains in pedagogical knowledge and experience, and they provided copies of class assessments and video recordings of their teaching. The PDs reported greater use of learner-centered compared with teacher-centered strategies. These data were consistent with the results of expert reviews of teaching videos. The majority of PDs (86%) received video ratings that documented active engagement of students and implementation of learner-centered classrooms. Despite practice of higher-level cognition in class sessions, the items used by the PDs on their assessments of learning focused on lower-level cognitive skills. We attributed the high success of the FIRST IV program to our focus on inexperienced teachers, an iterative process of teaching practice and reflection, and development of and teaching a full course.  相似文献   

Past/forward policy-making: transforming Chinese engineering education since the Reform and Opening-up     

Qin Zhu  Brent K. Jesiek  Yu Gong 《History of education》2015,44(5):553-574

Although engineering education has played important roles in China’s growing power and influence on the world stage, engineering education policy since the Reform and Opening-up in the late 1970s has not been well documented in current English-language scholarship. Informed by historical and sociological studies of education, engineering and engineering education, this paper attempts to address this scholarly gap by relating contemporary Chinese engineering education policy-making to its broader historical, cultural and ideological contexts. Based on analysis of policy documents and reports released by the Chinese government and engineering schools, and drawing on prior scholarship of Chinese (engineering) education policy, this paper employs the concept of ‘past/forward’ as an analytic lens to interpret and understand four major areas of engineering education policy change in contemporary China: institutional reform, disciplines and majors, training objectives, and curriculum reform.  相似文献

Longitudinal analysis of the environmental attitudes of university students     

Kerry Shephard  John Harraway  Tim Jowett  Brent Lovelock  Sheila Skeaff  Liz Slooten 《Environmental Education Research》2015,21(6):805-820

This article addresses the important questions that higher education institutions ask concerning their impact on their students’ sustainability-related attributes ‘How do our students’ worldviews change as they experience higher education with us?’ The process of monitoring such a dynamic entity is fraught with statistical complexity but may not be impossible for an institution willing to ask whether or not its educational efforts in ‘education for sustainability’, ‘education for sustainable development’ or ‘environmental education’, and campus sustainability developments, are paralleled by changes in the attitudes of its students. We describe here a longitudinal survey process based on the revised New Ecological Paradigm scale, with two cohorts of students, in three programmes of study, operating over four years, with multiple survey inputs by each student. We implemented the longitudinal analysis using a linear mixed-effects model and describe here the development and testing of this model. We conclude that higher education institutions can benchmark the sustainability attributes of their students and monitor changes, if they are minded to. We invite higher education practitioners worldwide to join us in further developing suitable research instruments, processes and statistical models, and in further analysing the assumptions that link higher education to sustainability and to global citizenship.  相似文献   

Smartphone-interfaced lab-on-a-chip devices for field-deployable enzyme-linked immunosorbent assay     

Arnold Chen  Royal Wang  Candace R. S. Bever  Siyuan Xing  Bruce D. Hammock  Tingrui Pan 《Biomicrofluidics》2014,8(6)

The emerging technologies on mobile-based diagnosis and bioanalytical detection have enabled powerful laboratory assays such as enzyme-linked immunosorbent assay (ELISA) to be conducted in field-use lab-on-a-chip devices. In this paper, we present a low-cost universal serial bus (USB)-interfaced mobile platform to perform microfluidic ELISA operations in detecting the presence and concentrations of BDE-47 (2,2′,4,4′-tetrabromodiphenyl ether), an environmental contaminant found in our food supply with adverse health impact. Our point-of-care diagnostic device utilizes flexible interdigitated carbon black electrodes to convert electric current into a microfluidic pump via gas bubble expansion during electrolytic reaction. The micropump receives power from a mobile phone and transports BDE-47 analytes through the microfluidic device conducting competitive ELISA. Using variable domain of heavy chain antibodies (commonly referred to as single domain antibodies or Nanobodies), the proposed device is sensitive for a BDE-47 concentration range of 10⁻³–10⁴μg/l, with a comparable performance to that uses a standard competitive ELISA protocol. It is anticipated that the potential impact in mobile detection of health and environmental contaminants will prove beneficial to our community and low-resource environments.  相似文献   

Intergenerational transmission of adaptive functioning: a test of the interactionist model of SES and human development     

Schofield TJ  Martin MJ  Conger KJ  Neppl TM  Donnellan MB  Conger RD 《Child development》2011,82(1):33-47

The interactionist model (IM) of human development (R. D. Conger & M. B. Donellan, 2007) proposes that the association between socioeconomic status (SES) and human development involves a dynamic interplay that includes both social causation (SES influences human development) and social selection (individual characteristics affect SES). Using a multigenerational data set involving 271 families, the current study finds empirical support for the IM. Adolescent personality characteristics indicative of social competence, goal-setting, hard work, and emotional stability predicted later SES, parenting, and family characteristics that were related to the positive development of a third-generation child. Processes of both social selection and social causation appear to account for the association between SES and dimensions of human development indicative of healthy functioning across multiple generations.  相似文献
