The change in epistemological beliefs and beliefs about teaching and learning: a study among pre-service teachers

This study investigated the change in Singaporean pre-service teachers' epistemological beliefs and beliefs about learning and teaching over the course of a teacher preparation program. An online survey was administered during the first week of a nine-month program and the same survey was administered after the 413 participants had completed all their course work and teaching practice. Participants exhibited significant changes in epistemological beliefs and beliefs about learning and teaching – participants indicated more relativistic epistemological outlooks and less constructivism in beliefs about teaching. At the end of the teacher preparation program, they seemed to less value effort in learning and believed more in innate ability.     

Education policy borrowing in China: has the West wind overpowered the East wind?

Recent education reform in China reflects the global trend of education policy borrowing from Anglophone countries such as the USA. The reform in China essentially advocates shifting from knowledge reproduction and didacticism to knowledge construction by students through a learner-centredness approach. Aware of the trend of borrowing policy from ‘Western’ countries, some educators in China use the proverb ‘the West wind has overpowered the East wind’ to describe this phenomenon. This paper examines the cultural factors that influence education policy borrowing in China by drawing upon Johnson’s metaphors of the ‘politics of selling’ and the ‘politics of gelling’. This paper argues that there exist fundamental cultural differences between Western and Chinese perspectives on the nature and transmission of knowledge that make education policy transfer in China challenging. This paper further proposes that China borrow education policy judiciously by integrating foreign and indigenous sources of knowledge, teaching and learning.     

Activity identification and classification in wheelchair rugby using fractal dimensions

The purpose of the study was to develop an evidence-based method for identification and classification of wheelchair sports (rugby) activities and performance during a match using fractal dimensions. The approach involves five wheelchair rugby athletes of different classifications who were monitored during six different matches using mobile devices with in-built accelerometers. The linear acceleration signals were processed using two different approaches based on calculating fractal dimensions. One was based on Rényi’s entropy, which produced the probability dimension (S ₀), and the other was based on Hausdorff’s definition, resulting in the Hausdorff dimension (D _H). When both dimensions were individually plotted as cumulative distribution plots, they offered two approaches to analyze the performance of a wheelchair rugby athlete. Combining the two dimensions produced a two-dimensional (2D) mapping that identified five different activities of each athlete during a wheelchair rugby match—(1) no activities, (2) low activities, (3) high-speed coasting, (4) high-speed pushing, and (5) extreme collisions. In the 2D mapping, four boundary lines separate the five different activities, which produced a template for each athlete. It was found in this research that the classification and skill level of the athlete had an effect on the boundary line values that form the template. The outcome of the activity identification was also verified by comparing with video footage of the athletes. The method developed in this research has possible applications for coaching, match analysis, and talent identification.     

Anatomical Sciences Education Vol. 5, Issue 4, 2012 Cover Image

A group of first year medical students at the Yong Loo Lin School of Medicine of the National University of Singapore study anatomy in the Anatomy Museum at this institution. Using an anatomical model, students discuss the extraocular muscles with their lecturers Drs. Boon‐Huat Bay (center) and Eng‐Tat Ang (third from left). In this issue of ASE, Dr. Ang and his colleagues review the past, present, and future of anatomy education in Singapore's three medical schools.     

Microfluidic device for trapping and monitoring three dimensional multicell spheroids using electrical impedance spectroscopy

In this paper, we report the design, fabrication, and testing of a lab-on-a-chip based microfluidic device for application of trapping and measuring the dielectric properties of microtumors over time using electrical impedance spectroscopy (EIS). Microelectromechanical system (MEMS) techniques were used to embed opposing electrodes onto the top and bottom surfaces of a microfluidic channel fabricated using Pyrex substrate, chrome gold, SU-8, and polydimethylsiloxane. Differing concentrations of cell culture medium, differing sized polystyrene beads, and MCF-7 microtumor spheroids were used to validate the designs ability to detect background conductivity changes and dielectric particle diameter changes between electrodes. The observed changes in cell medium concentrations demonstrated a linear relation to extracted solution resistance (Rs), while polystyrene beads and multicell spheroids induced changes in magnitude consistent with diameter increase. This design permits optical correlation between electrical measurements and EIS spectra.     

A comparative study on first-time and experienced project-based learning students in an engineering design module

This study aims to compare and evaluate the learning ability and performance differences between two groups of students undergoing project-based learning (PjBL), with one group having prior PjBL experience, while the other group is being freshly exposed to PjBL. More specifically, it examines if there are significant differences in knowledge score, problem-solving ability, and eventual project-deliverable outcomes between the two sets of students. Performances were compared via qualitative and quantitative analyses. Key findings have indicated a significant increase in fundamental formative knowledge; enhanced problem-solving abilities; and production of better performing artefacts with regard to the set of design skills between experienced and first-time PjBL groups. This study also highlighted that experienced PjBL students have less conflicts within their groups, and are more receptive to PjBL compared to first-time PjBL students. Results from this study provide a starting point for educators to seek new learning/facilitating strategies that are relevant based on the experience and learning styles of students.     

A study of Web 2.0 applications in library websites

Web 2.0 represents an emerging suite of applications that hold immense potential in enriching communication, enabling collaboration and fostering innovation. However, little work has been done hitherto to research Web 2.0 applications in library websites. This paper addresses the following three research questions: (a) To what extent are Web 2.0 applications prevalent in libraries?; (b) In what ways have Web 2.0 applications been used in libraries?; and (c) Does the presence of Web 2.0 applications enhance the quality of library websites? Divided equally between public and academic, 120 libraries' websites from North America, Europe and Asia were sampled and analyzed using a three-step content analysis method. The findings suggest that the order of popularity of Web 2.0 applications implemented in libraries is: blogs, RSS, instant messaging, social networking services, wikis, and social tagging applications. Also, libraries have recognized how different Web 2.0 applications can be used complementarily to increase the level of user engagement. Finally, the presence of Web 2.0 applications was found to be associated with the overall quality, and in particular, service quality of library websites. This paper concludes by highlighting implications for both librarians and scholars interested to delve deeper into the implementation of Web 2.0 applications.     

分解与实验:现代艺术的核心力量

现代艺术自19世纪末登上历史舞台,就以反传统的面貌和挑战的姿态奋力激进,不断震撼和改变着人们的视觉经验.分解与实验成为现代艺术发生发展过程中的核心力量.通过各个不同流派的艺术实践,色彩、空间、透视等绘画本体要素获得全面解放,这是对现代艺术分解与实验的有力证明.分解与实验使艺术回归到自身,色彩、线条、块面之间关系与组合具有独立意义.
