Agriculture, industry and medicine are being altered by new biotechnologies. Biotechnology education is important because todays students and citizens will make decisions about the development and application of these new molecular biologies. This article reports an investigation of the teaching of biotechnology in an Australian state, New South Wales (NSW). In NSW few students were electing to answer examination questions related to biotechnology, suggesting that few students were studying the topic. This study looks at why electives relating to biotechnology are chosen or not chosen by students and teachers, with the intention of developing a greater understanding of the requirements for provision of a successful unit of study in this subject. Data was obtained through a survey of secondary science teachers, interviews with teachers and two case studies of the teaching of a biotechnology unit. Teachers reported a range of obstacles to the teaching of biotechnology including the difficulty of the subject matter and a lack of practical work that was suited to the content of the teaching unit. If biotechnology is worth learning in school science, then further research is needed to identify ways to promote the effective teaching of this topic, which teachers regard as important for, and interesting to, students but which most teachers choose not to teach. 相似文献

We report on two studies in which high school students who had been exposed to a cognitive training procedure known as the Conceptual Mediation Program (CMP) were compared to students who had not participated within the program. In the first study, based on data from two sites, it was found that 70 CMP students exhibited higher levels of school affect and strategy awareness than 103 comparable students not in the program. In the second study, based on retrospective data from one site, 53 students who had participated within CMP classes were found to exhibit higher levels of attainment on Year 12 South Australian public examination results (effect size of 1.04 on the aggregate). On the Year 12 examination results, the CMP students outperformed both the school and state norms. 相似文献

Schools in Singapore are now tasked to develop the spirit of innovation and enterprise in their students. This is in line with the national vision of ‘Thinking Schools, Learning Nation’. This policy initiative, which began in 2004, is set to change the fundamental nature of education in Singapore. This article discusses the innovation and enterprise (I&E) initiative, its major implications for schools in Singapore and the areas still to be addressed in the implementation of the policy. In particular, the article discusses the issues of teachers and school leaders as role models of I&E, I&E as an organic part of school business, the influence of the wider societal culture and values system, and the measurement of success of I&E. The challenge for schools is to go beyond the form of the initiative to bring real substantial and sustainable change through this movement. 相似文献

Phenol degradation in photochemically enhanced Fenton process was investigated in this work. UV-VIS spectra of phenol degradation showed the difference between photo-Fenton process and UV/H2O2, which is a typical hydroxyl radical process. A possible pathway diagram for phenol degradation in photo-Fenton process was proposed, and a mathematical model for chemical oxygen demand (COD) removal was developed. Operating parameters such as dosage of H2O2 and ferrous ions, pH, suitable carrier gas were found to impact the removal of COD significantly. The results and analysis of kinetic parameters calculated from the kinetic model showed that complex degradation of phenol was the main pathway for removal of COD; while hydroxyl radicals acted weakly in the photo-Fenton degradation of phenol. 相似文献

In spite of the growing body of research on loneliness, the relationship between the phenomena of loneliness and boredom has not been sufficiently addressed, especially in respect to children. The question, “How does the child’s experience of boredom stand phenomenologically in relation to the experience of loneliness?” is explored from a hermeneutic phenomenological perspective. A critical examination of the literature regarding the phenomenology of both loneliness and boredom provides a theoretical background to the study. Elementary school children’s experiential accounts of loneliness and boredom are collected through research conversations. An original interpersonal communication board game is devised and used to initiate these conversations. The themes of loneliness and boredom emerged in a process of phenomenological reflection based on the participants’ lived experiences, the author’s personal experiences, and experiential accounts available in the literature. Distinctions between the two phenomena are derived from the exploration of these themes. Both boredom and loneliness are viewed as important pedagogical ingredients in the formation of the child’s inner self. 相似文献

Privatisation,Decentralisation and Education in the United Kingdom: The Role of the State 总被引:1,自引:0,他引:1

Since the early 1950s, the axis centralisation–decentralisation, especially as thematised in the work of Isaac Kandel, has represented a major focus of comparative studies in education. Kandel argued that issues relating to the internal conduct of the classroom (interna ) should, so far as possible, be decentralised, while issues relating to administration, school structure and organisation of the educational system (externa ) might safely be centralised. After 1988, successive governments in the United Kingdom have undertaken reforms which have placed more central control on the curriculum and even methods of teaching (interna ), while school finance and administration (externa ) have been devolved to the school level. The present essay argues that a simplistic approach to centralisation and decentralisation is not likely to be fruitful. Instead, we should acknowledge the role of the State in creating a permissive framework for educational systems. Local action can then be seen as part of a policy accommodating or resisting the implications of that framework. 相似文献

China’s dramatic economic rise has tended to overshadow other wider perspectives on the developing China and Association of Southeast Asian Nations (ASEAN) relationship, including in higher education. The article examines contemporary relations between China and ASEAN, set against the longer term development of cultural and trade relations. It is argued that, notwithstanding current territorial disputes, and a history of discrimination against ethnic Chinese in several parts of ASEAN, prospects for a deepening of relations in higher education remain strong. Singapore, Malaysia, and Vietnam are selected as three instances of the developing relationship in higher education and some of the links traced, with the former assessed as best placed to take advantage of its China relations in higher education. The developing sense of regionalism is seen as likely to further enhance China-ASEAN relations in higher education. 相似文献

Early years curricula promote learning through play and in addition emphasise the development of computer literacy. Previous research, however, has described that teachers feel unprepared to integrate Information and Communication Technology (ICT) and play. Also, whereas research has suggested that effective computer use in the early years is associated with adult direction, further research suggests adult presence can inhibit play and reduce children's engagement. Focusing on 12 settings following the Welsh play-based Foundation Phase, this paper explores teachers' experiences of integrating computer use into classroom practice, children's levels of engagement with computer activities and how playful children perceive computer use to be. Teachers confidently delivered a variety of computing experiences. Children consistently rated these activities as play regardless of adult presence and demonstrated moderate to high levels of engagement. Findings and the features of observed practice are discussed in relation to the teachers' role as a play partner and the successful co-construction of the play-based curriculum. 相似文献
