The purposes of the study were to assess preservice teachers’ domain-specific epistemological beliefs and to investigate whether preservice teachers distinguish disciplinary differences (physics, chemistry, and biology) in domain-specific epistemological beliefs. Mixed-method research design guided the present research. The researcher explored three epistemological dimensions: certainty and simplicity of knowledge, justification for knowing, and source of knowledge. Both quantitative and qualitative results suggested that a domain-specific epistemological beliefs system is a valid model to describe preservice teachers’ epistemological beliefs. In terms of epistemological beliefs, disciplinary differences in physics, chemistry, and biology were discussed in the last parts of the study. 相似文献

Many introductory biochemistry students have problems understanding metabolism and acquiring the skills necessary to study
metabolic pathways. In this paper we suggest that this may be largely due to the use of a traditional teaching approach which
emphasises memorisation rather than understanding. We present an alternative approach to teaching carbohydrate metabolism
which is designed to promote understanding of pathways. The approach also enables regular monitoring of, and reflection on,
student progress and the identification of student reasoning and conceptual difficulties through the use of specially designed
problems. Preliminary results are presented giving examples of specific student difficulties and the extent to which they
were addressed by the alternative instructional approach. A qualitative evaluation of the approach is also presented.

The use of problem-solving in science instruction implies a change in the teacher's role from dispensing content information
to encouraging critical reflective thinking in the student. For problem-solving to become an integral part of the science
curriculum, teachers must make it the focus of their instruction. This study investigated the extent to which pre-service
primary teachers used the problem-solving approach in their science instruction. It also identified the factors affecting
their efforts to teach science using this approach. The issues considered are important in whether problem-solving becomes
part of the science curriculum, as teaching behaviour influences student learning outcomes.

The main objective of this research paper is to introduce the concept of medical libraries, and to survey the present status of medical libraries in the State of Bahrain in terms of their history, collections, staff, and services. The study gives a general background about the State of Bahrain and its libraries. It also discusses the main problems facing medical libraries in Bahrain. Finally, the study gives some recommendations for developing medical libraries in Bahrain. Personal interviews and documents were used for collecting the information. 相似文献

The notion that technology is the application of science to the making of artefacts is a widely-held, persistent and influential
view. Considerable scholarly work has been done during the past quarter century to refute it on the grounds that it is historically
and ontologically inaccurate. It is a view which fails to recognise the contribution of non-scientific factors to technological
development,which neglects the reverse contribution of technology to science, and which offers a superficial account of the
process of application. This paper focusses on this last point, and argues that in those cases where science is applied to
technology, the application process is usually exceedingly complex. The process involves the selection of appropriate knowledge,
the adoption of differing criteria and the translation and re-shaping of knowledge to make it amenable to the technologist.
The issue has important implications for the school curriculum.

Abstract This article represents a meta-analysis of three research KEYWORDS projects undertaken recently at the National Foundation for Educational children in Research. The projects were discrete but resultant data showed that they care; had a common focus: ways in which schools do or might accommo-disaffection; date more effectively the needs of a range of pupils who are at risk of inclusion; being denied the opportunity to experience the ‘normality’ of the cur-special riculum offered by schools in England and Wales. The pupils whose educational experiences were studied had special educational needs, and/or were needs ‘disaffected’, and/or were in the public care. While their circumstances were, thus, ostensibly various, analysis showed that they were underpinned by a common set of needs which, unaddressed by the education system, resulted in the exclusion of the pupils. Strategies that effectively nurtured pupils’ inclusion were found to be applicable across the client group. 相似文献
