Searching for good practice in teaching: a comparison of two subject‐based professional learning communities in a secondary school in Shanghai

Since the mid‐1990s, the concept of professional learning communities has arisen in the education field in the West, aiming to improve teachers’ professional competency by using collaborative approaches. Western studies indicate that these strategies help teachers achieve professional growth. Schools in China have had a long history of enhancing the professional competency of teachers by using collaboration in school‐based contexts. But do professional learning communities in Chinese schools, especially in times of change, do the same for Chinese teachers? This study provides empirical data from Chinese teachers to assist global discussions on school‐based professional development. The study uses qualitative data collection methods, including semi‐structured interviews, observations and documentary analysis, to investigate how teachers from two subject departments in a secondary school in Shanghai enhance their knowledge and practice within their subject‐based professional learning communities. Results show that members of these two communities have shared common goals and have developed a sense of collective accountability. The study also found that socio‐cultural factors, such as the collectivist values, authoritarian‐oriented practices and influences of interpersonal relationship, are crucial in the development of Chinese professional learning communities, even though different communities may differ in other respects.     

The construction of parents and teachers as agents for the improvement of municipal schools in Chile

This article examines how teachers and parents in 10 municipal schools serving students growing up under conditions of social vulnerability represented themselves, and others, as valid agents for charting school improvement. In four schools parents and teachers saw each other as trustworthy and collaborating to provide an education that could transform students’ life chances. In the other six schools, social relations were marked by distrust, staff constructed students as lacking the resources necessary to benefit from a rigorous academic programme, and parents in leadership positions shared with teachers the belief that school failure could largely be attributed to uncommitted parents. These results suggest that the impact of quality assurance policies tends to be associated with the social capital of municipal schools, thus educational policy needs to consider developing and strengthening social capital within schools.     

Pre-service teachers' dispositions towards diversity: Arguing for a developmental hierarchy of change

This article explores Australian pre-service teachers' beliefs about and attitudes towards diversity. Building on Garmon's [Garmon, M. A. (2004). Changing preservice teachers' attitudes/beliefs about diversity: what are the critical factors? Journal of Teacher Education, 55(3), 201–213] argument that there are three dispositional factors that influence students' likelihood of developing multicultural awareness and sensitivity in teacher education programmes, the authors explore the relationship between such dispositions as exhibited in students' autoethnographic work. In so doing, the authors posit that these dispositions may be hierarchically developed: beginning from ‘self-awareness/self-reflectiveness’; moving towards ‘openness’; and finally a ‘commitment to social justice’. After exploring the nature of this hierarchical development through the in-depth investigation of six representative student accounts, the paper concludes by discussing the implications for teacher education, including the necessity to adjust our expectations of changing the dispositions of pre-service teachers in discrete, short courses.     

The efficacy of final examinations: A comparative study of closed-book, invigilated exams and open-book, open-web exams

Educators have long debated the usefulness (or otherwise) of final examinations; a debate that has typically revolved around the relative merits of closed-book exams, open-book exams, take-home exams or their substitution by some other assessment format (eg, project work). This paper adds a new dimension to the debate by considering how the final examination assessment instrument might be enhanced through harnessing the power of technology, more specifically, how the learner experience of the final examination might be made more authentic and, in the process, more constructively aligned with stated learning outcomes. The authors report on the latest findings of an ongoing research project evaluating the effectiveness of 'open-book, open-web' (OBOW) examinations delivered by an online university, vis-à-vis a closed-book, invigilated alternative. Earlier research had indicated that the OBOW model receives the strong endorsement of students in a number of respects, most particularly the quality of the learning outcomes.     

The impact of the use of response pad system on the learning of secondary school physics concepts: A Singapore quasi-experiment study

Although a number of researchers have examined response pad systems (RPSs) in higher education, there has been very little research at the K-12 level. This paper investigated the impact of using an RPS in the learning of physics concepts in a secondary school in Singapore. Two classes ( n  = 35 students in each class) of secondary five students participated in this study. One of the classes used an RPS while the other did not. Both classes completed a pretest and a posttest which tested the students in the application of the physics concepts taught. Results suggested that the class that used an RPS performed better in the posttest compared to the class that did not use the system. In addition, we explored the teacher and students' perceptions of using the RPS.     

Efficient page layout analysis on small devices

Previously we have designed and implemented new image browsing facilities to support effective offiine image contents on mobile devices with limited capabilities： low bandwidth, small display, and slow processing. In this letter, we fulfill the automatic production of cartoon contents fitting small-screen display, and introduce a clustering method useful for various types of cartoon images as a prerequisite stage for preserving semantic meaning. The usage of neural networks is to properly cut the various forms of pages. Texture information that is useful for grayscale image segmentation gives us a good clue for page layout analysis using the multilayer perceptron （MLP） based x-y recursive algorithm. We also automatically frame the segment MLP using agglomerative segmentation. Our experimental results show that the combined approaches yield good results of segmentation for several cartoons.
