ABSTRACT

In recent years, there has been increasing interest within the engineering education research community to prepare engineering students to address wicked problems (WPs) such as climate change, resource scarcity and violent conflict. Previous research suggests that engineering students are able to address WPs if they are given adequate support, but there is a lack of research on what kinds of support are needed. This paper aims to reduce this gap by reporting on students’ performance in, and approaches to, addressing WPs when different scaffolding strategies were used in different parts of a rubric-based intervention. The intervention aimed to provide undergraduate engineering students with an understanding of the nature of WPs and with a structured way of addressing them. For each part of the intervention, we discuss affordances for learning provided by the different scaffolding strategies. The results suggest that strong cognitive scaffolding can support students’ understanding of the nature of WPs and students’ performance in written responses to WPs, but possibly also limits deep engagement with WPs and transfer of learning to other contexts.  相似文献

Icelandic parents' views on the national policy on early childhood education     

Johanna Einarsdóttir 《Early Years: An International Journal of Research and Development》2010,30(3):229-242

Considerable change has taken place in Icelandic early childhood education during the past few decades. Preschool, from being geared primarily towards children with evident social needs, has become all but universal. The aim of this study was to shed light on Icelandic parents' views on their children's preschool education and to examine how their views harmonize with the nation's preschool policy. The participants in this study, 43 parents of five‐ and six‐year‐old children in three preschools in Reykjavík, participated in focus‐group interviews concerning the preschool curriculum. The results indicate that the parents' main expectation of the preschools was that they should support the children's social development; the way in which the preschool day was organized, and the content of the curriculum seemed to be less important to them. Parents wanted their children to have the opportunity not only to enjoy themselves as individuals, but to learn self‐reliance and respect for other people. Care‐giving and attentiveness of the staff were more important than the teaching of knowledge and skills. These views are compatible with the social pedagogical tradition, the Icelandic Preschool Act, and the National Curriculum Guidelines for Preschools.  相似文献   

Stress and risk for depression in competitive athletes suffering from back pain – Do age and gender matter?†     

Johanna Belz  Jahan Heidari  Claudia Levenig  Monika Hasenbring  Michael Kellmann  Jens Kleinert 《European Journal of Sport Science》2018,18(7):1029-1037

Back pain (BP), a prominent problem for competitive athletes, is a primary reason for limitations in athletic performance and daily life restrictions. As studies on the relationship between psychological variables and BP in athletes are scarce, the aim of this study was to investigate stress and depression in competitive athletes with BP. In a cross-sectional design, data of 154 competitive athletes (51% female; M_age?=?18.81 years, SD_age?=?5.05 years) were collected, assessing Performance stress, Socio-emotional stress, Risk for depression and Psychological well-being and the two BP parameters BP Intensity and Disability. Two multiple linear regressions were conducted to predict (1) BP Intensity and (2) Disability from Performance stress, Socio-emotional stress, Risk for depression and Psychological well-being. Multiple linear regressions demonstrated that Performance stress (β?=?.21, p?=?.01) was the only significant predictor of BP Intensity (F_1,142?=?6.68, p?=?.01, R²?=?.05), whilst Risk for depression (β?=?.24, p?=?.01) was the only significant predictor of Disability (F_1,142?=?8.46, p?=?.01, R²?=?.06). Neither gender nor age explained a significant amount of variance in the models. Study results showed that, as in the general population, the variables stress and depression are related to BP in competitive athletes. In particular, BP intensity was found to be associated with stress and BP-related disability was associated with depression, whereas age and gender showed no association with the BP parameters. A longitudinal investigation is warranted to determine the direction of the observed relationships.  相似文献

Differences between motion capture and video analysis systems in calculating knee angles in elite-standard race walking     

Brian Hanley  Catherine B. Tucker  Athanassios Bissas 《Journal of sports sciences》2018,36(11):1250-1255

Race walking is an event where the knee must be straightened from first contact with the ground until midstance. The aim of this study was to compare knee angle measurements between 2D videography and 3D optoelectronic systems. Passive retroreflective markers were placed on the right leg of 12 race walkers and 3D marker coordinate data captured (250 Hz), with 2D video data (100 Hz) recorded simultaneously. Knee angle data were first derived based on the markers’ coordinates, and separately by using a 3D model that also incorporated thigh and shank clusters; the video data were analysed using both automatic tracking and manual digitising, creating four conditions overall. Differences were calculated between conditions for stance (using root mean square values), and at discrete events. There were few differences between systems, although the 3D model produced larger angles at midstance than using automatic tracking and marker coordinates (by 3 – 6°, P < 0.05). These differences might have occurred because of how the 3D model locates the hip joint, and because of the addition of marker clusters. 2D videography gave similar results to the 3D model when using manual digitising, as it allowed for errors caused by skin movement to be corrected.  相似文献   

An analysis of alterity in teachers’ inclusive pedagogical practices     

Johanna Sagner-Tapia 《International Journal of Inclusive Education》2018,22(4):375-390

This investigation contributes to understanding how teachers reflect on the other with a disability and on their own practices. Literature suggests that inclusion takes place when barriers are removed, allowing participation. However, scholars agree that teachers still struggle with pedagogical practices in inclusive classrooms. Hansen (Hansen, J. H. 2012. “Limits to Inclusion.” International Journal of Inclusive Education 16 (1): 89–98) contends that teachers establish limits to inclusion in order to manage the level of diversity, arguing that the limits depend on the teacher’s understanding of disability. This article examines German secondary school teachers, who reflect on inclusive pedagogical practices and their relationship to learners with disabilities. The analysis shows that most teachers add levels of complexity when constructing the disability’s identity. Teachers struggled with the notion of limitation associated with disability and with the discovery of the other, with new learning skills and abilities. Interactions with learners with a disability open new venues to practice inclusion and encourage participation, but this requires a change in practices; yet, not all teachers feel prepared to do that. Teachers offered various rationales on why they applied limits to inclusion; those rationales are rooted in how they interpret disability and their own roles as teachers.  相似文献   

Analysis of lower limb internal kinetics and electromyography in elite race walking     

Brian Hanley  Athanassios Bissas 《Journal of sports sciences》2013,31(11):1222-1232

Abstract

The aim of this study was to analyse lower limb joint moments, powers and electromyography patterns in elite race walking. Twenty international male and female race walkers performed at their competitive pace in a laboratory setting. The collection of ground reaction forces (1000 Hz) was synchronised with two-dimensional high-speed videography (100 Hz) and electromyography of seven lower limb muscles (1000 Hz). As well as measuring key performance variables such as speed and stride length, normalised joint moments and powers were calculated. The rule in race walking which requires the knee to be extended from initial contact to midstance effectively made the knee redundant during stance with regard to energy generation. Instead, the leg functioned as a rigid lever which affected the role of the hip and ankle joints. The main contributors to energy generation were the hip extensors during late swing and early stance, and the ankle plantarflexors during late stance. The restricted functioning of the knee during stance meant that the importance of the swing leg in contributing to forward momentum was increased. The knee flexors underwent a phase of great energy absorption during the swing phase and this could increase the risk of injury to the hamstring muscles.  相似文献   

Change in Teacher Education: interpreting and experiencing new professional roles     

David Blake  Vince Hanley  Mike Jennings  Michele Lloyd 《欧洲师范教育杂志》1996,19(1):19-34

In this paper we consider the effect of moves by the British Government to make initial teacher education (ITE) in England and Wales more school‐based (Blake, 1993). To monitor the impact of this shift towards school‐based training we conducted a fine grain study of what was happening on the ground within the one‐year Secondary School‐Based Postgraduate Certificate in Education (PGCE) at the Chichester Institute of Higher Education (ChIHE). * *At the time the research was conducted, the Institute's name was the West Sussex Institute of Higher Education, hence interviewees refer to ‘WSIHE’ and ‘West Sussex’. View all notes Data were gathered from questionnaire surveys and interviews. Findings from our regional case study indicate that while school‐based ITE programmes may offer student teachers greater insight into school life, this should not be at the expense of developing students’ analytical and theoretical understanding of education and schooling promoted within higher education‐based work.  相似文献   

The recruitment of VET teachers and the failure of policy in England’s further education sector     

Pam Hanley 《Journal of Education & Work》2019,32(2):103-114

England’s further education (FE) sector has been characterised by instability and policy churn for at least three decades during which time reform of vocational education and training (VET) has been piled on top of reform, with few resulting in lasting change. In the context of another ambitious new reform of VET in England, this article reports on a study that examined the chronic difficulties in recruiting teachers of vocational science, engineering and technology (SET) to FE colleges. We argue that these difficulties in recruiting SET teachers reveal persistent weaknesses in policy planning for the English VET sector and help to explain the serial failure of VET policy in England.  相似文献
