This study examines how student practice of scientific argumentation using socioscientific bioethics issues affects both teacher expectations of students’ general performance and student confidence in their own work. When teachers use bioethical issues in the classroom students can gain not only biology content knowledge but also important decision-making skills. Learning bioethics through scientific argumentation gives students opportunities to express their ideas, formulate educated opinions and value others’ viewpoints. Research has shown that science teachers’ expectations of student success and knowledge directly influence student achievement and confidence levels. Our study analyzes pre-course and post-course surveys completed by students enrolled in a university level bioethics course (n = 111) and by faculty in the College of Biology and Agriculture faculty (n = 34) based on their perceptions of student confidence. Additionally, student data were collected from classroom observations and interviews. Data analysis showed a disconnect between faculty and students perceptions of confidence for both knowledge and the use of science argumentation. Student reports of their confidence levels regarding various bioethical issues were higher than faculty reports. A further disconnect showed up between students’ preferred learning styles and the general faculty’s common teaching methods; students learned more by practicing scientific argumentation than listening to traditional lectures. Students who completed a bioethics course that included practice in scientific argumentation, significantly increased their confidence levels. This study suggests that professors’ expectations and teaching styles influence student confidence levels in both knowledge and scientific argumentation. 相似文献
By age 2, children are developing foundational language processing skills, such as quickly recognizing words and predicting words before they occur. How do these skills relate to children’s structural knowledge of vocabulary? Multiple aspects of language processing were simultaneously measured in a sample of 2-to-5-year-olds (N = 215): While older children were more fluent at recognizing words, at predicting words in a graded fashion, and at revising incorrect predictions, only revision was associated with concurrent vocabulary knowledge once age was accounted for. However, an exploratory longitudinal follow-up (N = 55) then found that word recognition and prediction skills were associated with rate of subsequent vocabulary development, but revision skills were not. We argue that prediction skills may facilitate language learning through enhancing processing speed. 相似文献
eParticipation is an emerging research area which, like most emerging areas, lacks a clear literature base or research approach. This study maps out some of the academic theories and disciplines that the new area addresses, using conventional literature study techniques. We identify 99 articles that are considered to be highly relevant to eParticipation. We develop a definitional schema that suggests different ways of understanding an emerging research area, and use this schema to identify key academic articles that help to define eParticipation. We adapt Deetz's [(1996). Describing differences in approaches to organization science: Rethinking Burrell and Morgan and their legacy. Organization Science, 7(2), 191–207] taxonomy of discourses in organizational science to provide an overall categorization scheme for research in the area, and map the literature. The article thus contributes to a developing picture which will help future researchers both to understand and to navigate the research area. 相似文献
Parents are usually anxious about the quality of pre‐school education for their children and Singapore is no exception. As such, research into quality indicators of pre‐school care and education continues to receive much attention, especially in terms of identifying which aspects are related to positive outcomes for children, their parents and the policy makers. However, the significance of the day to day pre‐school experiences per se, are rarely investigated. Rather than considering outcomes, this paper reports a study which is concerned with pre‐school teachers' views on selected aspects of their working environment, in particular their dealings with parents, as determinant measures of quality in pre‐schools.
The majority of pre‐school centres in Singapore have a central structure and environment which by necessity adheres to government regulations. Except for teachers' views and feelings about aspects of their working conditions, most of the usual measures of centre quality are regulated. The study is concerned to identify which features of their day to day encounters most satisfactorily contribute to their roles as pre‐school teachers, and to examine any differences attributable to qualifications and experience.
The results show, that whilst there are some differences between teachers according to qualifications and experience, amongst the most positive features are satisfaction with parents' involvement, children's behaviour, and positive support from other teachers. 相似文献
ABSTRACTThis study focuses on how young people read and discuss two political documentary films, Labor Day and Hillary: The Movie. We were specifically interested in the impact of the film viewing and discussion on participants’ beliefs about the issues in the films, how they view evidence and expertise in the films, and how the session impacted their views of documentaries as a source. Groups were designed according to composite political scores and individuals (n?=?30) were selected to form liberal, conservative, and two mixed groups (strong and moderate) for the viewing and discussion. Our analysis illustrates the power of political ideology in shaping how expertise is viewed and how evidence is warranted in film – and the role of social context and peer discussion in this process. Implications for media and democratic education in times of political polarization are discussed. 相似文献
Members of this research team are investigating the use of multipoint desktop video conferencing (MDVC) technology in Singapore to enhance the National Institute of Education's schools practicum partnership model. The project builds on the Singapore ONE ATM island-wide network and the high-speed ADSL line access provided by Singtel Magix. This infrastructure provides state-of-the-art support for the White Pine CU-SeeMe Meeting Point server and client software that enables students on teaching practice to conference with each other and their university-based supervisors. A typical conference involves four of five students at different schools and one staff member at the National Institute of Education in Singapore. These conferences provide opportunities for professional sharing between staff and students without the limits of time and space which are traditional constraints on conventional teaching practice. 相似文献
