Not only are the problems teachers pose throughout their teaching of great importance but also the ways in which they use those problems make this a critical component of teaching. A problem-posing episode includes the problem setup, the statement of the problem, and the follow-up questions. Analysis of problem-posing episodes of precalculus instructors suggests that their mindset influences how they pose problems. In this paper, we describe the reflexive relationship between an instructor’s mindset and problem-posing episodes. 相似文献

In this study we investigate how federal and state policy makers, and school principals are working to improve science teacher
quality. Interviews, focused discussions, and policy documents serve as the primary data source. Findings suggest that both
policy makers and principals prioritize increasing incentives for teachers entering the science teaching profession, providing
professional development for new teachers, and using students’ data to evaluate and improve instruction. Differences between
the two leadership groups emerged in terms of the grain size and practicality of their concerns. Our findings indicate that
the complexity of educational challenges to improve science teacher quality call for the co-construction of policy by multiple
constituent groups including school principals, federal and state policy makers, and science education researchers. 相似文献

前言 ２０世纪５０年代以来，人们发现肠里葡萄糖的存在促进钠的转运（Ｒｉｋｌｉｓ＆Ｑｕａｓｔｒｅｌ，１９５８），这个里程碑式的发现引发口服补水溶液配方的产生。为满足水、碳水化合物和电解质最大限度的吸收，精确配制这些溶液的问题激起了相当多的科学研究和讨论。 口服补水溶液一直是由葡萄糖、蔗糖、果糖、多精、谷物淀粉或由这些糖混合，并添加不同种类的电解质（如钢、氯、钾、柠檬酸盐、碳酸氢盐），而配制成低渗至高渗的溶液。这些溶液在十二指肠空肠、回肠和结肠的吸收。已在兔子、鼠、狗、猫和人身上得到了测试。 大多数的… 相似文献

Early literacy interventions have demonstrated that pedagogically sound programmes can boost reading achievement for students who do not succeed in early literacy learning. However, there is less evidence as to what extent gains are maintained in subsequent years or the factors which may contribute to sustained progress. The research reported in this article employed a cross‐sectional design to investigate the achievement of students who had previously participated in Reading Recovery. Two to four years after successfully completing the intervention, students were assessed in reading and writing by using standardised assessment tools. Although 60% of students had retained parity in reading in comparison with their age cohort, 40% were markedly below the mean of the cohort and the national norm. Data from case study schools provide some initial suggestions for school implementation factors which affect continued success. Conclusions regarding the need to plan for sustainability of gains following early intervention are made. 相似文献

Faculty and student engagement in the Argentine grassroots rebellion: toward a democratic and emancipatory vision of the university 总被引：2，自引：0，他引：2
Following Argentina’s economic collapse of December 2001, the authors examine the engagement of university faculty and students
in various grassroots movements. Based on a qualitative study involving 24 formal structured interviews, 18 informal interviews,
observation-based field work, and document analysis, the authors identify key forms of faculty and student engagement as well
as the manner in which individuals discussed the relationship between universities and society. Findings are used to advance
the idea of a more democratic and emancipatory vision of the contemporary university and build on the work of Boaventura de
Sousa Santos. Throughout the article, the authors ground their discussion in international/comparative literature addressing
globalization, neoliberalism, university reform, and social movements.

The Mathematics of Estimation: Possibilities for Interdisciplinary Pedagogy and Social Consciousness
The purpose of this article is to report on the importance of providing pre-service and in-service teachers with experience
and specific training in critical thinking skills. The essential concepts in elementary mathematics curricula can be augmented
to include and cultivate critical thinking skills that have tremendous ramifications for future leaders and for those who
move on to more technical training. A sample problem, along with pre-service teacher responses, is used here to show the necessity
and importance of this kind of training as the responses show clear evidence of a certain naivete on the part of these college
level students. The responses do show evidence of budding social conscience in the students, but the level of expertise in
critical thinking is not at all sophisticated. We discuss and explore the implications of our approach. 相似文献

基于全球范围内四所大学的案例研究,本文探讨并深入阐述了"学术公民身份"的概念,着重讨论了作为学术公民的学生和教职员如何应对全球化带来的挑战和机遇。在研究广东外语外贸大学、加州大学洛杉矶分校、布宜诺斯艾利斯大学和中欧大学等四所高校的学术公民的职业与生活时,作者指出全球化的一些重要特征,并且在所有被研究的区域中全球资本主义都在改变学术生活的本质。作为学术公民的学生与教职员采取创造性的方式来面对强大的全球力量,这也可能正是当今大学为实现其社会转型所寻求的。 相似文献
