形成性评价（Formative Assessment）的本质及其对教与学的影响

长期以来,很多学者一直倡导指导教学的评价,即通过评估学生需求和监测其学习进展,适当地设计学习顺序,调整教学策略,改良学习计划,以便有效地促进学习目标的完成。本研究调查了形成性评价在美国中学科学课中的实施情况,并分析其对学生学习进步的影响。研究表明,教师都在努力使用形成性评价来指导教学,而学生取得的成绩各不相同。     

Helping Students Develop Statistical Reasoning: Implementing a Statistical Reasoning Learning Environment

This article describes a model for an interactive, introductory secondary‐ or tertiary‐level statistics course that is designed to develop students' statistical reasoning. This model is called a ‘Statistical Reasoning Learning Environment’ and is built on the constructivist theory of learning.     

Improving the academic outcomes of undergraduate ESL students: the case for discipline‐based academic skills programs

This article examines the impact of an adjunct English language tutorial program on the academic performance of first‐year Architecture students. With increasing numbers of international students enrolling in Australian universities, language and academic skills programs have shifted from generic to more discipline‐specific models; however, there has been little research on the effects of these programs on ESL students' academic performance. This study uses a mixed‐method approach to evaluate the effectiveness of an English as a second language (ESL) intervention program. Findings indicate that students value a highly discipline‐specific approach to language and academic skills support and that regular participation in a content‐based ESL program can lead to positive learning outcomes for students. Preliminary findings also suggest that there are positive longer‐term benefits on students' academic outcomes. The authors suggest the need for longitudinal studies on the impact of discipline‐based programs for ESL students.     

Youth cultures,activism and agency: revisiting feminist debates

Following the invitation issued by the London Feminist Salon Collective in the pages of Gender and Education, this paper offers further theoretical suggestions for understanding agency. Based on an ethnographic study with young people engaged in activist politics, I offer a conception of agency that is at its core relational. I build this theoretical contribution upon a lineage of feminist theorising about the nature of agency, which began in debates about poststructuralism/postmodernism but have since moved to incorporate Pierre Bourdieu's cultural sociological approach. I suggest that while previous theorising has been enormously important for yielding insights into the possibilities for agency, it has not adequately accounted for the everyday means by which agency takes place. My empirical work highlights one of the modalities through which young people come to take political action – that is, through relational processes. I suggest that such an understanding about agency can further illuminate the means by which progressive and feminist goals might be reached.     

Device physics vis-à-vis fundamental physics in Cold War America: the case of quantum optics

Historians have convincingly shown the close ties U.S. physicists had with the military during the Cold War and have raised the question of whether this alliance affected the content of physics. Some have asserted that it distorted physics, shifting attention from fundamental problems to devices. Yet the papers of physicists in quantum electronics and quantum optics, fields that have been exemplary for those who hold the distortion thesis, show that the same scientists who worked on military devices simultaneously pursued fundamental and foundational topics. This essay examines one such physicist, Marlan O. Scully, with attention to both his extensive foundational studies and the way in which his applied and basic researches played off each other.     

What university teachers teach and how they teach it

In this article we make three related arguments. The first isthat different teachers have different intentions concerning whatstudents will learn and consequently in their teaching they constitutethe topic or subject to be taught quite differently. The second is thata teacher's intentions concerning what it is that students should learnis closely aligned with a teacher's expectation of how students learnand how they can be helped to learn through teaching. The third is thatwhen teachers focus specifically on the teaching of a particular topic,within a specific context, there is a close relationship between theirintentions and their teaching practice. In this article we explore thesearguments through an empirical study which considers the different waysin which 26 university teachers intended to constitute a subject ortopic for their students to study, how they then taught the subject andsubsequently how consistent were their intentions and their practice.The analysis shows that when the context of teaching and learning istightly defined there is a clear relationship between a teacher'sintention and their practice. In particular, university teachers whoadopt more conceptual change and student-focussed approaches to teachingconstitute objects of study which are more relational and focus on thestudent's knowledge. Approaches which are more information transmissionand teacher-focussed constitute objects of study which are moremulti-structural and have a focus on knowledge which is as constitutedas being external to the student.     

Diplomas for learning, not seat time: the impacts of New York Regents examinations

Economic theory predicts that improvements in signaling of achievement generated by external exit examination systems will (1) result in students learning more and this in turn will (2) enable them to get better paying jobs. Since New York State had the only statewide curriculum-based external exit exam system in the nation in the early 1990s, hypothesis 1 predicts that New York students should out perform socio-economically comparable students from other states. Cross section analysis of mean 8th grade NAEP math scores and SAT-I scores found that New York students were indeed about one grade level equivalent ahead of where one would expect given their socio-economic background. A similar analysis of dropout rate data found no differences between New York and other states. Hypothesis 2 was tested in HSB and NLS-88 data. Female students who reported that their high school required they pass a minimum competency exam in order to graduate were paid significantly more after they graduated from high school. Men did not earn more but did get a higher hourly wage.
