This paper explores the potential of technology-enabled feedback to improve student learning. ‘Technology, Feedback, Action!: The impact of learning technology upon students’ engagement with their feedback’ aimed to evaluate how a range of technical interventions might encourage students to engage with feedback and formulate actions to improve future learning. The study used qualitative methods and worked in partnership with 23 undergraduate students to explore their experiences of receiving different forms of feedback with varying degrees of technical intervention including, but not limited to, electronic feedback with grades withheld; online grade publication; criteria-based feedback; and more traditional feedback methods. Through a series of semi-structured interviews, student participants were encouraged to articulate their experiences of feedback. The online publication of grades and feedback and the adaptive release of grades were found to significantly enhance students’ engagement with their feedback. Data were analysed using a thematic approach, and the main themes were used to inform the development of a series of good practice guides. The findings are discussed in the context of current literature.  相似文献   

Examining increased flexibility in assessment formats     

Brian Irwin  Stuart Hepplestone 《Assessment & Evaluation in Higher Education》2012,37(7):773-785

There have been calls in the literature for changes to assessment practices in higher education, to increase flexibility and give learners more control over the assessment process. This article explores the possibilities of allowing student choice in the format used to present their work, as a starting point for changing assessment, based on recent studies and current examples of flexible assessment practice in higher education. The benefits of this flexible assessment format approach are highlighted, along with a discussion of classic assessment considerations such as validity, reliability and marking concerns. The role of technology in facilitating assessment method choice is considered, in terms of new opportunities for providing student choice in the way they evidence their learning and present their work. Considerations for implementing flexible assessment choices into the curriculum are presented, along with a call that further research into such practice is needed to develop a comprehensive set of practical recommendations and best practice for the implementation of flexible assessment choice into the curriculum. The article should be of interest to curriculum developers and academics considering implementing changes to the assessment process to increase student ownership and control.  相似文献

New Directions,New Relationships: The Smithsonian's Twenty‐first Century Learning in Natural History Settings Conference and the Natural History Museum,London     

Brad Irwin  Emma Pegram  Honor Gay 《Curator: The Museum Journal》2013,56(2):273-278

The Twenty‐first Century Learning in Natural History Settings Conference at the Smithsonian Institution, Washington, D.C. (2012) has been more influential than similar conferences, resulting in new work streams and international collaborations for the Learning Research and Evaluation team at the Natural History Museum, London (NHM). The conference offered a rare opportunity to discuss issues relevant to our unique workplace and to be surrounded by an instant peer group. Although the event itself brought personal and professional satisfaction, it is the impact of the conference on our institution that has been most fulfilling. The conference has enabled us to think bigger—to think about the sector as a whole and the role the NHM can play as a large national museum.  相似文献

Phase analysis in maximal sprinting: an investigation of step-to-step technical changes between the initial acceleration,transition and maximal velocity phases

Abstract

The aim of this study was to investigate spatiotemporal and kinematic changes between the initial acceleration, transition and maximum velocity phases of a sprint. Sagittal plane kinematics from five experienced sprinters performing 50-m maximal sprints were collected using six HD-video cameras. Following manual digitising, spatiotemporal and kinematic variables at touchdown and toe-off were calculated. The start and end of the transition phase were identified using the step-to-step changes in centre of mass height and segment angles. Mean step-to-step changes of spatiotemporal and kinematic variables during each phase were calculated. Firstly, the study showed that if sufficient trials are available, step-to-step changes in shank and trunk angles might provide an appropriate measure to detect sprint phases in applied settings. However, given that changes in centre of mass height represent a more holistic measure, this was used to sub-divide the sprints into separate phases. Secondly, during the initial acceleration phase large step-to-step changes in touchdown kinematics were observed compared to the transition phase. At toe-off, step-to-step kinematic changes were consistent across the initial acceleration and transition phases before plateauing during the maximal velocity phase. These results provide coaches and practitioners with valuable insights into key differences between phases in maximal sprinting.  相似文献   

Sport-specific musculoskeletal growth and postural control in female artistic gymnasts: a 12 month cohort study

Abstract

Female gymnasts have been evidenced to experience sport-specific growth, of which broad shoulders and narrow hips are common characteristics. In addition to being a central component of handstand performance, postural control mechanisms, including whole-body and lumbo-pelvic stability, have been identified as risk factors for overuse spinal pathology. The study aimed to develop a fundamental understanding of musculoskeletal growth and postural control responses of female artistic gymnasts in order to extend longitudinal insights into overuse spinal pathology risk. Whole-body anthropometric measures were collected for 12 competitive female gymnasts (age at recruitment: nine to 15 years) at three time points across a 12 month period. Musculoskeletal growth was partially defined as the rate of bicristal-to-biacromial breadth ratio development, and informed shoulder- and pelvis-dominant growth sub-groups. Kinematic and kinetic indicators of postural control were determined for a total of 700 handstand trials. The shoulder-dominant (gymnastics-specific) growth group was found to have significantly greater biomechanical risk for general stability (p < 0.001) than the pelvis-dominant group. Significantly greater lumbo-pelvic risk was demonstrated for the pelvis-dominant group (p < 0.001). Extended idiosyncratic examination of proportional sport-specific growth measures alongside multi-faceted risk monitoring was advocated for the effective development of future overuse pathology prevention protocols.  相似文献

Lower limb joint kinetics and ankle joint stiffness in the sprint start push-off   总被引：1，自引：0，他引：1

Sprint push-off technique is fundamental to sprint performance and joint stiffness has been identified as a performance-related variable during dynamic movements. However, joint stiffness for the push-off and its relationship with performance (times and velocities) has not been reported. The aim of this study was to quantify and explain lower limb net joint moments and mechanical powers, and ankle stiffness during the first stance phase of the push-off. One elite sprinter performed 10 maximal sprint starts. An automatic motion analysis system (CODA, 200 Hz) with synchronized force plates (Kistler, 1000 Hz) collected kinematic profiles at the hip, knee, and ankle and ground reaction forces, providing input for inverse dynamics analyses. The lower-limb joints predominately extended and revealed a proximal-to-distal sequential pattern of maximal extensor angular velocity and positive power production. Pearson correlations revealed relationships (P < 0.05) between ankle stiffness (5.93 ± 0.75 N x m x deg(-1)) and selected performance variables. Relationships between negative power phase ankle stiffness and horizontal (r = -0.79) and vertical (r = 0.74) centre of mass velocities were opposite in direction to the positive power phase ankle stiffness (horizontal: r = 0.85; vertical: r = -0.54). Thus ankle stiffness may affect the goals of the sprint push-off in different ways, depending on the phase of stance considered.  相似文献
