Environmental education in primary schools: a case study with plastic resources and recycling     

Winnie Wing Mui So  Stephen Cheuk Fai Chow 《Education 3-13》2019,47(6):652-663

This paper aims to examine teachers’ use of strategies and approaches in integrating Plastic Resources Education (PRE) into primary school life in order to overcome the challenges encountered during implementation to promote environmentally friendly practices. Case studies with eight Hong Kong teachers from PRE-participating primary schools were invited to take part in focus group interviews, to explicate their personal stories and experiences associated with the PRE implementation in primary schools. Based on the data collected from the teachers’ sharing, several challenges which are commonly reported in the previous literature, including lack of time, shortage of manpower, and insufficient pupil engagement were found. The teachers tackled the barriers by using different strategies to improve pupils’ involvement as well as getting support from the relevant stakeholders of school management and parents. The case studies provide crucial and relevant information which can be used as a reference for other schools to integrate PRE more efficiently to facilitate learning.  相似文献   

Designing a Responsive e-Learning Infrastructure: Systemic Change in Higher Education     

Anthony S. Chow  Rebecca A. Croxton 《The American journal of distance education》2017,31(1):20-42

As university administrators respond to increasing demands of the educational market to offer greater opportunities for online learning, their capacity to create an economically stable, sustainable, yet rich teaching and learning environment deserves immediate and continued attention. A university-wide study involving 130 participants examined the e-learning perceptions and needs of faculty, students, and staff as part of a needs assessment of the e-learning unit. Results suggest that faculty recognize the importance of e-learning, that students covet it for its convenience, and that real-time technology support was the top priority. Both the school and university resources, however, are not well aligned to meet these needs and remain largely separate and unintegrated. Implications suggest a need to increase the overall ease of use for the adoption of e-learning as a new technology for teaching and learning of both faculty and students and more closely aligned department and university resources.  相似文献   

Methodological Approaches to Comparing Pedagogical Innovations Using Technology     

Nancy Law  Angela Chow  Allan H. K. Yuen 《Education and Information Technologies》2005,10(1-2):7-20

The study of educational innovations has become increasingly important in education research as many countries around the world have embarked on education reforms that aim to change both the goals and practices in education. There is also a general expectation that such innovations can be leveraged or supported by the use of information and communication technology (ICT) in the learning and teaching process. However, comparative studies of innovations are relatively rare. SITES M2, as an international comparative study of innovative pedagogical practices involving 28 participating systems, thus faced important methodological challenges the solution of which was no less an innovation in itself. This paper examines the methods of analysis used and the kind of research findings that resulted from the work of three research teams that had conducted comparisons of the case studies of innovation collected, including the work of the SITES M2 International Coordinating Centre (ICC). Even though all three studies attempted to examine similarities and differences across multiple case studies, the analysis conducted by the ICC looked for characterizations of the innovations while the other two studies developed meaningful ways to compare the cases in terms of levels of innovation across a number of dimensions. In discussing the methodological differences across these studies, this paper pays special attention to how one could compare different innovations in terms of their levels or extents of innovation and what such comparisons may contribute to our learning from technology-supported education innovations.  相似文献   

Image Capital,Field, and the Economies of Signs and Space     

Carol Pui-Ha Chow 《The Communication Review》2013,16(4):251-270

Drawing upon the concept of cultural capital, this article develops image as a form of Bourdieusean capital to examine what Lash and Urry identify as the economies of signs and space. Image capital refers to the accumulated labor of visual resources that allows agents possessing it to yield power. The concept of image capital will differentiate the power of images from the power of linguistic signs in the age of mediation.  相似文献   

Combining Cultural Analytics and Networks Analysis: Studying a Social Network Site with User-Generated Content     

Almila Akdag Salah  Lev Manovich  Albert Ali Salah  Jay Chow 《广播与电子媒介杂志》2013,57(3):409-426

Humanities and social sciences require new research approaches to deal with and to benefit from the explosion of digital media. Thanks to large scale data storage and processing, close reading of individual items can be supplemented with analysis of broader trends from massive amounts of data. Cultural Analytics (CA) is a recently developed methodology for the exploration of content and visual form in large image and video collections. It has already been applied to a variety of media types, including TV programs, feature films, newspapers, and video games. However, until now these applications did not take into account the social context of media. In many cases, media artifacts under scrutiny are generated or used by people in a social setting, either in forms of (digital) communities, or in terms of social relations, which can be also analyzed as a valuable source of information. Social network analysis (SNA) is a set of methods for the analysis of human networks, including massive online social networks. In this article, we argue that CA and SNA can be combined synergistically, using data and images from deviantArt, the leading online network of user-created art, as a case study.  相似文献

Kinematic analysis of shot-putting performed by wheelchair athletes of different medical classes     

John W. Chow  Woen-Sik Chae  Michael J. Crawford 《Journal of sports sciences》2013,31(5):321-330

The aim of this study was to identify those kinematic characteristics that are most closely related to an athlete's medical classification and measured distance of a put. Two S-VHS camcorders (60 fields per second) were used to record the performance of 17 males of different classes. Each participant performed six trials and the best trial for each was selected for analysis. Three-dimensional kinematics of the shot and upper body segments at the instant of release and during the forward thrust (delivery) were determined. The average speeds and angles of the shot at release for different classes (5.3-7.8 ms -1 and 21.2 to 34.4°, respectively) were smaller than those exhibited by elite male able-bodied throwers. The height of the shot at release, the angular speed of the upper arm at release, the range of motion of the shoulder girdle during the delivery, and the average angular speeds of the trunk, shoulder girdle and upper arm during the delivery, were all significantly correlated with both the classification and measured distance ( P ? 0.05). The results indicate the importance of achieving a high average angular speed for each upper body segment during the delivery.  相似文献   

Year-long teacher professional development on fifth grade student science outcomes     

Carolyn Nichol  Alice Chow  Scott Furtwengler 《International Journal of Science Education》2013,35(17):2099-2117

ABSTRACT

We first examined the effects of a year-long professional development (PD) programme for elementary science teachers on fifth grade student performance on state-mandated science achievement tests of students from a treatment and a comparison group of teachers in the 2009–2010 academic year. Then, we investigated the longer-term impacts by comparing the 2010–2011 student test results of the teachers one year after receiving treatment in 2009–2010 with the students of teachers who received treatment during 2010–2011. Test scores were analysed using a propensity score matching method to examine the relationship between the PD and student achievement. Results showed that even though the treatment teachers were out of the classroom 20% of the school year to attend the PD, there was no difference between their students’ science achievement scores and those of the comparison teachers who were in the classroom every day. This is an important finding because many principals and parents are reluctant to provide teachers with release time for PD. We also determined that students of teachers one year after participating in the PD significantly (p?<?0.001) with a medium effect size (η²?=?.088) outperformed students of teachers who had just completed the programme. This suggests that it takes time for teachers to implement new teaching strategies and that to observe the impact of an intervention programme, it may be important to expand the timeframe of the programme evaluation.  相似文献   

Pre-movement and during-movement visual search behaviours vary depending on expertise and anxiety levels in ten-pin bowling     

Wan Xiu Goh  Bernice H. Y. Lim  Matthew James Wylde  Michele Macnaughton  Jia Yi Chow 《Journal of sports sciences》2018,36(18):2076-2086

This study investigated the pre-movement and during-movement visual search behaviour (VSB) and quiet eye (QE) of 11 elite versus 10 sub-elite ten-pin bowlers, performing under high-anxiety and low-anxiety conditions. Pre-movement and independent of expertise, bowlers had more fixations and directed them to more locations when performing under high-anxiety compared with low-anxiety. Elite bowlers fixated at more locations closer to the pins in pre-movement than during-movement, with pre-movement QE occurring mostly at the breakpoint and middle arrows. During movement however, bowlers fixated closer to the foul-line at the middle and right dots and arrows, with during-movement-QE occurring at the middle dots and right arrows. Elite bowlers recorded longer QE durations during-movement rather than pre-movement, albeit a later onset during the longish five-step approach prior to ball release compared with sub-elite bowlers. Our results suggest that QE during-movement instead of pre-movement could be more pertinent in differentiating expertise during sporting tasks with a long movement phase and far-aiming target. The relevance of pre-movement or movement-QE in characterising expertise and performance could therefore be sport-dependent. This should be considered when investigating skilled action and developing training programs for skill acquisition.  相似文献   

Why Johnny Can't Prove     

Tommy Dreyfus 《Educational Studies in Mathematics》1999,38(1-3):85-109

The one sentence answer to the question in the title is that the ability to prove depends on forms of knowledge to which most students are rarely if ever exposed. The paper gives a more detailed analysis, drawing on research in mathematics education and classroom experiences.This revised version was published online in September 2005 with corrections to the Cover Date.  相似文献
