Unpacking the paradox of Chinese science learners: insights from research into Asian Chinese school students’ attitudes towards learning science,science learning strategies,and scientific epistemological views

Chinese students’ excellent science performance in large-scale international comparisons contradicts the stereotype of the Chinese non-productive classroom learning environment and learners. Most of the existing explanations of this paradox are provided from the perspective of teaching and learning in a general sense, but little work can be found which systematically summarises the findings from the research on Chinese science learners and their science learning so as to explain the paradox. In this paper, a total of 25 empirical quantitative studies, whose sample sizes range from 132 to 8815, published between 1987 and 2014, are reviewed. Three aspects are explored: students’ science learning strategies, attitudes towards learning science and their scientific epistemological views. In addition to summarising the results reported in these studies, efforts are made to link them with the paradox of the Chinese learners, and to generate some hypotheses to resolve it. Finally, directions for further research are suggested.     

Teacher collaborative learning through the lesson study: identifying pathways for instructional success in a Singapore high school

Research shows teacher collaborative learning to be a powerful vehicle to mobilise teacher instructional change and pedagogical practices, and to improve student achievement. For such undertakings to have positive impact, understanding the visible features of collaborative structures may not be sufficient to ensure sustainable practice. Instead, there is a need to identify underlying pathways that provide for successful instructional improvement. The purpose of this qualitative study is to obtain deeper insights into teacher outcomes arising from this practice and to identify aspects of the lesson study structure and processes that afford such opportunities. Three subject groups consisting of ten teachers from a Singapore high school participated in this study. Implications on staff development programs will be discussed in the light of these findings.     

继续教育不应冷落书法教育

书法是我国传统文化,在我国继续教育领域中几乎冷落了书法教育。致使我国国民书写水平较差,书法素养极低,很难适应我国物质文明和精神文明的高度发展。继续教育要开展好书法教育,应从四个方面做好工作:转变观念,端正对书法教育的思想认识;建立相关考核评价制度;加强师资培训;建立健全书法研讨团体,培养一批书法测试员。     

Sexuality in Older Adults: Effect of an Education Intervention on Attitudes and Beliefs of Residential Aged Care Staff

The sexual needs and wellbeing of older people living in residential aged care receives scant attention in practice, is easily dismissed by care staff, and remains a significant challenge for aged care service providers. This study reports on the evaluation of an education program delivered to residential aged care nurses to improve their knowledge about, and attitudes towards, older people's sexuality in this context. Participants' attitudes and beliefs towards older people expressing their sexuality in long-term care, including same sex couples and people with dementia, were more permissive following education. Findings further underscore the value of sexuality education as an important factor in dispelling the commonly held negative views of residential aged care staff about older people expressing their sexuality, thereby improving staff responses to this issue.
