The purpose of this study was to evaluate the traction characteristics of four different stud configurations on Fédération Internationale de Football Association (FIFA) 2-Star, third-generation artificial soccer turf. The investigated stud configurations were hard ground design, firm ground design, soft ground design, and an experimental prototype. The concept of this study combines performance, perception, biomechanical, and mechanical testing procedures. Twenty-five soccer players took part in the different testing procedures. Variables of this study were: running times, subjective rankings/ratings, ground reaction forces, and mechanical traction properties. Statistical discrimination between the four stud configurations was shown for performance, perception, and biomechanical testing (p < 0.05). Unsuited stud configurations for playing on artificial turf are characterized by less plain distributed and pronounced studs.  相似文献

Can Wii Engage College-Level Learners? Use of Commercial Off-the-Shelf Gaming in an Introductory Statistics Course     

Jessica A. Stansbury  Evangeline A. Wheeler  Justin T. Buckingham 《学校用计算机》2014,31(1-2):103-115

Technological advancements and growing dependence on media outlets as sources of information compete for the attention of individuals born in a rapidly expanding digital age. As a result, educators using traditional, nondigital teaching methods struggle with keeping students engaged in the classroom. The present study assessed the extent to which a digitally enhanced learning environment can improve student involvement in learning. A traditional behavioral statistics lecture was supplemented with Nintendo Wii video gaming to increase student content knowledge comprehension and engagement with course material. A mixed Analysis of Variance (ANOVA) revealed that those in the video gaming condition improved significantly more than those receiving traditional lecture only. This research suggests that students can learn difficult conceptual material (i.e., statistics) through more novel, interactive teaching methods.  相似文献   

Students’ use of personal technologies in the university classroom: analysing the perceptions of the digital generation     

Debra Langan  Nicole Schott  Timothy Wykes  Justin Szeto  Samantha Kolpin  Carla Lopez 《Technology, Pedagogy and Education》2016,25(1):101-117

Faculty frequently express concerns about students’ personal use of information and communication technologies in today’s university classrooms. As a requirement of a graduate research methodology course in a university in Ontario, Canada, the authors conducted qualitative research to gain an in-depth understanding of students’ perceptions of this issue. Their findings reveal students’ complex considerations about the acceptability of technology use. Their analysis of the broader contexts of students’ use reveals that despite a technological revolution, university teaching practices have remained largely the same, resulting in ‘cultural lag’ within the classroom. While faculty are technically ‘in charge’, students wield power through course evaluations, surveillance technologies and Internet postings. Neoliberalism and the corporatisation of the university have engendered an ‘entrepreneurial student’ customer who sees education as a means to a career. Understanding students’ perceptions and their technological, social and political contexts offers insights into the tensions within today’s classrooms.  相似文献   

NARST: a lived history

In this Forum, we construct a history of the National Association for Research in Science Education (NARST) through the analysis of documents and through the personal perspectives of individuals. The history of NARST is inseparable from the biography of the individuals through whose lives it was produced and reproduced. The history of NARST is a living history that both shapes and was shaped by the biographies of its members.

Exploring students’ epistemological knowledge of models and modelling in science: results from a teaching/learning experience on climate change     

Giulia Tasquier  Olivia Levrini  Justin Dillon 《International Journal of Science Education》2016,38(4):539-563

The scientific community has been debating climate change for over two decades. In the light of certain arguments put forward by the aforesaid community, the EU has recommended a set of innovative reforms to science teaching such as incorporating environmental issues into the scientific curriculum, thereby helping to make schools a place of civic education. However, despite these European recommendations, relatively little emphasis is still given to climate change within science curricula. Climate change, although potentially engaging for students, is a complex topic that poses conceptual difficulties and emotional barriers, as well as epistemological challenges. Whilst the conceptual and emotional barriers have already been the object of several studies, students’ reactions to the epistemological issues raised by climate changes have so far been rarely explored in science education research and thus are the main focus of this paper. This paper describes a study concerning the implementation of teaching materials designed to focus on the epistemological role of ‘models and the game of modelling’ in science and particularly when dealing with climate change. The materials were implemented in a course of 15 hours (five 3-hour lessons) for a class of Italian secondary-school students (grade 11; 16–17 years old). The purpose of the study is to investigate students’ reactions to the epistemological dimension of the materials, and to explore if and how the material enabled them to develop their epistemological knowledge on models.  相似文献   

Comparison of most‐to‐least to error correction for teaching receptive labelling for two children diagnosed with autism     

Justin B. Leaf  Aditt Alcalay  Jeremy A. Leaf  Kathleen Tsuji  Alyne Kassardjian  Stephanie Dale  John McEachin  Mitchell Taubman  Ronald Leaf 《Journal of Research in Special Educational Needs》2016,16(4):217-225

Prompting systems are guidelines of when to provide learners with prompts and when to fade prompts. Today, there are several prompting systems implemented to teach receptive labeling to individuals diagnosed with autism spectrum disorders and other disabilities. This study compared most‐to‐least prompting to an error correction procedure involving feedback and remedial trials for teaching two children with autism a variety of receptive labels. All teaching was implemented in a one‐to‐one instructional setting. Researchers taught each participant how to receptively identify 18 pictures; nine were taught using error correction and nine were taught using most‐to‐least. The researchers utilized an adapted alternating treatment design nested into a multiple probe design to evaluate the two procedures. Results indicated that participants were able to reach mastery criterion on 100% of skills taught using the error correction and were able to reach mastery criterion on 88.9% of skills taught using most‐to‐least. Additionally, error correction tended to require fewer trials for participants to reach mastery criterion.  相似文献   

“Kind,Sensitive, and Above All,Honest”: Long-Term Cancer Survivors’ Quality of Life and Self-Advocacy     

Kristian G. E. Borofka  Justin P. Boren 《Communication Research Reports》2013,30(4):373-378

ABSTRACT

Long-term survivors of cancer (LTS) are a growing population whose needs differ significantly from patients undergoing cancer treatment. Many LTS suffer from late effects of cancer treatments or symptoms that persist after treatment concludes or appear following remission. This study explored the relationship between LTS perceptions of quality of life with late effects and perceptions of patient self-advocacy through quantitative and qualitative analyses. A negative statistical relationship emerged between the variables. LTS median self-advocacy scores were quite high, reflecting their preference for health-care providers who listen actively, understand patient needs, are knowledgeable and compassionate, and utilize joint decision making.  相似文献

Articulation Visibility at Two-Year Colleges     

Mark Fincher  Lance Sharp  James Burks  Kelly Lyon  Mitchell Parker  Justin Ward 《Community College Journal of Research & Practice》2013,37(7):684-692

Articulation between two-year colleges and universities provides a critical opportunity for potential students. Most institutions declare their support of articulation; however, the visibility of this support to potential students is inconsistent at best. Articulation agreements that are visible and easily understood by potential students serve as a motivation to the pursuit of higher education. Conversely, the lack of a complete, visible path to a baccalaureate degree is a powerful deterrent to enrollment. For this study, articulation is a coordinated effort and process to support efficient transfer between institutions of higher education. (DeMott, 1999 DeMott , J. ( 1999 ). Seven steps to articulation success . High School Magazine , 6 , 22 – 24 . [Google Scholar]). The purpose of this study is to explore the general visibility of existing articulation opportunities at two-year colleges. The visibility of articulation agreements is a critical practical factor in their potential positive impact on student behavior and success.  相似文献
