Recent Chinese migrant students from Taiwan studying science in two Australian secondary schools were found to explain the
meanings of selected science concept labels in English by translating from Chinese. The research strategy involved interviewing
the students concerning their recognition and comprehension of the science concept labels firstly in Chinese and then in English.
Mean recognition and comprehension scores were higher in Chinese than in English, with indications that Chinese language and
science knowledge learnt in Chinese deteriorated with increasing time of residence in Australia. Rudimentary signs of the
students being able to switch between Chinese and English knowledge bases in science were also found. Implications for teaching
science to ESL students and suggestions for further research are discussed. 相似文献

Breaktimes are ubiquitous in English schools. Research suggests they have social value for children, but school staff often have a range of concerns about breaktimes and tend to undervalue them. However, there is little understanding about these times, not least because data are not collected about their organisation and characteristics. This paper brings together data from three national surveys undertaken in 1995, 2006 and 2017 of head teachers of primary and secondary schools to provide an understanding of the nature, organisation and staff attitudes towards breaktimes and how they have changed over 25 years. At each survey point, completed questionnaires were received from representative random samples of over 1000 primary and secondary schools. Results showed marked reductions in the average total amount of time for breaks, the virtual abolition of afternoon breaks and a decline in time available for lunchtime breaks. The reductions were largely for behavioural reasons and to increase time for learning. Results also show variations in the length of breaktimes across school types and in relation to socioeconomic disadvantage, and changes to the amount of supervision provided by schools. Attitudes towards breaks varied across primary and secondary phases, and the withholding of breaks was used by schools to address poor pupil behaviour and disengagement. Schools continued to have concerns about the management of behaviour during breaktimes, even when breaks had already been shortened. It is suggested that staff undervalue the potential contribution that breaktimes afford the development and wellbeing of children and young people in school. 相似文献
