We contrast the current science education reform effort with the reforms of the 1960s and suggest how the current effort could be enhanced. We identify insights from recent research that we believe can inform the reform process, in particular, to reach all science students and also impart a cohesive view of science. We propose an alternative models view of scientific explanation and show how this view would contribute to reforms of (1) course goals, (2) social aspects of science learning, (3) instructional practices, and (4) roles for technology.This paper summarizes discussions and debates that the authors have had over the last few years. The dialogue stems, in part, from our joint participation in the American Educational Research Association Special Interest Group on Education in Science and Technology (AERA SIG:EST) leadership. This paper communicates the spirit of our thinking and does not necessarily reflect the view of SIG:EST, or any other organization.We gratefully acknowledge the support of National Science Foundation Grant MDR-9253462 in work related to this paper. We appreciate helpful comments from Eileen Lewis and the Computer as Learning Partner group.This material is based upon research supported by the National Science Foundation under grant RED-9155744. Any opinions, findings, and conclusions or recommendations expressed in this publication are those of the authors and not necessarily reflect the views of the National Science Foundation.  相似文献

ABSTRACT

South Africa stands out in the African region for its protection of lesbian, gay, bisexual, transgender and intersex (LGBTI) rights. This article examines South Africa’s contributions to local policy for LGBTIs and to work on LGBTI issues in education policy and education rights progress internationally. It also considers broader South African contributions to the theorisation of gender and sexuality. Data derive from an analysis of 102 interviews with key informants participating in high-level global networking for LGBTI students’ rights, and documentary analysis showing how stakeholders characterise South African contributions to transnational LGBTI education work. Informants identified how such contributions have a strong human rights emphasis, furthering post-colonial resistance to simplistic gender and sexuality classification schema imposed via imperial colonising dynamics. While South African work in this area has also promoted and facilitated research, it has at times been limited by ambivalence from its leadership. The nation’s early adoption of constitutional rights, relationship rights and educational equity provisions as acts of decolonisation contribute valuable African LGBTI work examples to the region. Their success encourages further funding for South-South transnational LGBTI education work.  相似文献

The present study examined characteristics of students who took advantage of the opportunity to learn Algebra II from a highly skilled teacher. In particular, student information was gathered concerning: (a) the amount of mathematics students knew prior to the class, (b) their motivation for learning mathematics, (c) the number and types of interactions they had with the teacher during class, (d) degree of self-regulation, and (e) general aptitude. A model for achievement was used that suggests both opportunity and propensity are important (i.e., students must be willing and able to take advantage of opportunity). Support for the model was found. Propensity to take advantage of a highly favorable opportunity accounted for almost sixty percent of the variance in achievement. In particular, students who were self-regulated, had strong mathematics backgrounds, and had low levels of frustration benefited more from high-quality instruction.  相似文献

It has been widely documented that accountability systems, including school inspections, bring with them unintended side effects. These unintended effects are often negative and have the potential to undo the intended positive effects. However the empirical evidence is limited. Through a European comparative study we have had the rare opportunity to collect empirical evidence and study the effects (both intended and unintended) of school inspections (a key system of accountability) in a systematic way, across seven countries. We present the findings of the unintended effects in this paper. Survey self-report responses from school principals in each country, with differing school inspection systems, are analysed to measure the prevalence of these unintended effects and to investigate the part played by pressure to do well in inspections. A key finding is that increasing pressure in school inspection systems is associated with the undesired effect of the narrowing and refocusing of the curriculum and instructional strategies. We also show that a proportion of school principals admit to misrepresenting the school in data sent to the inspectorate and show evidence for formalisation/proceduralisation (excessive focus on records) and ossification (fear of experimentation in teaching), although these factors are less related to changes in pressure.  相似文献

This paper is an investigation of understandings of critical thinking from two teaching perspectives: academic staff and tutors. It explores critical thinking as situated within an assessment task in introductory macroeconomics. This study found that while the two academic staff conceptualized critical thinking as a set of concrete cognitive skills, the tutors challenged this notion. Although tutors used the way of understanding critical thinking identified by the academic staff in their teaching and marking, they also discussed broader notions of critical thinking that they saw as a fundamental aspect of the discipline. The paper examines the multiple constructions of critical thinking in this setting and its broader implications.  相似文献

Photoresist technology, which is used for micro-patterning exploits changes in properties of polymeric materials, such as their solubility or volatility, upon photo-irradiation. This process has greatly benefitted from the knowledge base of organic chemistry and photo-induced organic transformations. The role of chemistry in the development of photoresists is described in this article.  相似文献
