Factors and Interactions Influencing Technology Integration During Situated Professional Development in an Elementary School

This study examined factors that influence K–5 teachers’ technology integration efforts during a semester-long Collaborative Apprenticeship. Results suggest that shared planning time, shared curriculum, connection to an individual, expertise, physical proximity, and comfort level influenced interactions across the community of practice. Posing and responding to task-based questions, giving and seeking advice, and sharing ideas composed more than 70% of interactions between teachers. However, the nature of interactions changed as teachers assumed increased responsibility for designing technology-enhanced lessons. Teacher-leaders initially modeled exemplar applications of technology-enhanced lessons and gave advice on their classroom use. Subsequently, the community of teachers brainstormed ideas collaboratively as teacher-leaders supported peers to develop original lessons independently. Implications for collaborative apprenticeships and learning in professional environments are provided.     

Active engagement,emotional impact and changes in practice arising from a residential field trip

This study focused on the learning experiences of 50 undergraduate students undertaking a residential field trip (RFT) to Sweden as part of their Early Childhood Studies degree. Three dimensions were examined: the physical and emotional value afforded to the students from the active learning context; how this was interpreted and reflected in their knowledge, understanding and personal practice once they had left university; and the influence of factors such as age, and professional status on students' practice. The methodology was interpretive, and both deductive and inductive approaches were employed to analyse qualitative, narrative data sets derived from semi-structured questionnaires, interviews and written essays. The findings suggested that the physiological effects of hands on engagement influenced both the students' perceptions of the learning experience and their confidence to become agents of change. Subsequent changes directly attributed to the RFT experience, involved the re-evaluation of both the stereotypical pedagogic role and the way in which they related to children; students re-conceptualised their practices to reflect a more child-centred approach and increased their use of outdoor play and sustainable resources. The RFT was a catalyst that promoted empowerment, and informed both personal and professional transformations.     

Eight-season epidemiological study of injuries in men’s international Under-20 rugby tournaments

The aim of this study was to define the incidence and nature of match injuries sustained in men’s international under-20 rugby. The study comprised an 8-season prospective study of 16 international under-20 rugby tournaments. Procedures complied with the consensus statement for epidemiological studies in rugby. Outputs included players’ mean age, stature and body mass and incidence, severity, location, type and cause of match injuries. The overall incidence of injury was 49.7 injuries/1000 player-match-hours (backs: 48.3; forwards: 50.9) with a mean severity of 32.2 days-absence (backs: 29.4; forwards: 34.4). There were no significant changes in incidence or severity of injury over the study period. Shoulder/clavicle (18.3%), head/face (16.4%), knee (13.7%) and ankle (13.7%) were the most common injury locations and ligament sprain (35.4%), haematoma/bruise (15.9%), concussion (12.5%) and muscle strain (11.2%) the most common types of injury. Being-tackled (29.2%), tackling (24.0%) and collisions (14.3%) were the most common events leading to injury. The results confirm that international under-20 rugby has a high incidence and severity of injury but the incidence is half that reported for senior international players. There was no significant change in the overall incidence of injury at the Under-20 level in the period 2008 to 2016.     

Student laboratory presentations as a learning tool in anatomy education

Previous studies have shown that anatomy students who complete oral laboratory presentations believe they understand the material better and retain it longer than they otherwise would if they only took examinations on the material; however, we have found no studies that empirically test such outcomes. The purpose of this study was to assess the effectiveness of oral presentations through comparisons with other methods of assessment, most notably, examination performance. Specifically, we tested whether students (n = 256) performed better on examination questions on topics covered by their oral presentations than on other topics. Each student completed two graded, 12‐minute laboratory presentations on two different assigned topics during the course and took three examinations, each of which covered a third of the course material. Examination questions were characterized by type (memorization, pathway, analytical, spatial). A two‐way repeated measures analysis of variance revealed that students performed better on topics covered by their presentations than on topics not covered by their presentations (P < 0.005), regardless of presentation grade (P > 0.05) and question type (P > 0.05). These results demonstrate empirically that oral presentations are an effective learning tool. Anat Sci Educ 2: 260–264, 2009. © 2009 American Association of Anatomists.     

A link between students’ discernment of variation in unidirectional change and their use of quantitative variational reasoning

In this design experiment study, we investigated the problem: What conditions might foster students’ discernment of a critical aspect—variation in unidirectional change (e.g., discerning a “decreasing” increase)? At a public middle school in a large US city, we led a sequence of three days of whole class lessons, followed by task-based, clinical interviews with 14 seventh grade students (~?13 years old). Students interacted with researcher-developed dynamic computer environments, which linked filling polygon animations with dynamic graphs. We report results to demonstrate a range of students’ work along with detailed analyses of student interview episodes. We found connections between students’ predictions of graph type (linear, “mostly” linear, nonlinear), students’ conceptions of attributes represented by a graph, and students’ discernment of variation in unidirectional change. Students who discerned variation in unidirectional change also engaged in quantitative variational reasoning. To foster students’ discernment of variation in unidirectional change, task designers should provide opportunities for students to conceive of attributes as capable of varying and possible to measure.     

Physical Activity in Former Competitive Athletes: The Physical and Psychological Impact of Musculoskeletal Injury

Although competitive athletes exceed recommendations for physical activity while they are competing in sport, this does not necessarily translate into regular physical activity after retirement from sport. Research suggested the nature of competitive sport participation may not be conducive to lifelong physical activity. We propose one element of competitive sport participation that may impede physical activity post-retirement is injury. We propose that Vela and Denegar’s model of transient disablement in the physically active with musculoskeletal injuries (DPA) may be appropriate to examine the long-term consequences of sport-related injury—particularly with respect to physical activity disablement. Based on our review of literature, we propose the physical and psychological effects of injuries in sports present unique long-term barriers to physical activity in former competitive athletes. Future research could use the DPA as a foundation for assessing the long-term implications of sport-related injuries—particularly with respect to physical activity.     

A person-centred approach to understanding cultures of assessment

The purpose of the present study was to investigate how faculty members coalesce into distinguishable groups in terms of their perceived cultures of assessment at their respective institutions. To date, although researchers have posited the existence of various cultures of assessment, no study to our knowledge has empirically demonstrated the presence of these unobserved (latent) cultures analytically. Accordingly, a latent profile analysis was conducted using Mplus to identify these unobserved groups based on faculty (n = 1148) members’ responses to 12 items (6-point Likert scale) selected from the 2014 Faculty Survey of Assessment Culture. The resulting 4-class solution, including a previously unidentified group, was confirmed by the Lo-Mendell-Rubin Adjusted Likelihood Ratio Test: Culture of Student Learning (n = 502); Evolving Student Learning Culture (n = 398); Culture of Compliance (n = 168); and Culture of Fear (n = 80). Characteristics of each class are described and the prevalence of each class by type of degree granting institution and primary discipline is provided.

社会认识论:知识政策的理论与实践(上)

作为一种自然主义的进路,社会认识论处理的是围绕着知识过程及其产品的组织而展开的诸多规范性问题.换句话说,它是要在我们如何认识以及认识什么的基础上.致力于应该如何认识以及应该认识什么方面提供指导.这个题材相当于实用主义哲学家通常所说的"探究引导",以及今天的读者可能看起来是科学政策的抽象形式的东西.社会认识论取得了超出其它知识理论的进展,因为它重视这种情况,即生产知识的行为人不仅体现为个体,而且还以集体性的方式嵌于某些在相当大的时空范围上扩展的、可以具体指明的关系之中.并且,对于社会认识论者来说.知识的目标是需要确立的,而不是想当然的.诸如"有效性"、"可靠性"之类的语词.甚至"真理"一词本身都没有涉及探究行为的目标.它们只是涉及探究的诸多约束,以至于仍然留下很多有关知识的目的的问题悬而未决:应该生产什么种类的知识?由谁生产?为谁生产?知识政策要抓住的是那种对付这些问题的活动,而这些问题往往被常规的科学政策所忽视.
