数学的对称美及其作用 总被引:1,自引:0,他引:1
田鹏 《南阳师范学院学报》2004,3(3):113-115
对称美是数学美的重要组成部分,它普遍存在于初等数学与高等数学的各个分支。对称美在数学研究中有重要作用,它是数学创造与发现的美学方法之一。对称美在数学解题中也有广泛的应用,在解题过程中,考虑对称美的因素有时可起到事半功倍的效果。 相似文献

Schools have a particular responsibility to introduce young people to the range of possible options for them after they leave education as few families can provide this. However, in the United Kingdom, careers education is currently not strong in most schools for a number of reasons but principally due to its low status and shifts in government policy and funding. As a result, too many young people make subject choices for post-16 study that they subsequently regret. In particular, fewer young people in the United Kingdom choose post-16 STEM subjects than might do. Yet, STEM (science, technology, engineering and mathematics) graduates are especially valued by employers. We draw on the findings of two research projects, ASPIRES and UPMAP, and argue that one way forward may be to embed careers education in STEM lessons. This can be done in ways that are respectful of and helpful to students. We recommend that an England- or UK-based project to investigate the consequences of embedding careers education in STEM lessons be undertaken. 相似文献

Video has assumed an increasingly prominent role in teacher education, particularly in the form of the viewing of videotaped
class lessons by preservice teachers. Yet there is little research that confirms whether preservice teachers attend to the
aspects of the video(s) that teacher educators anticipate or desire. This article explores this issue and reports on the impact
of video viewing as a means to improve teachers’ ability to be observers of classroom practice. We utilized a pre- and post-test
design to measure the quantity and type of classroom events that preservice mathematics teachers noticed before and after
a teaching methods course where improving observation skills was an explicit goal. The results of the pre-assessment suggest
that preservice teachers generally do not enter teaching methods courses with well-developed observation skills. The post-assessment
indicates that the course led to significant increases in preservice teachers’ observation skills, particularly in teachers’
ability to notice features of the classroom environment, mathematical content of a lesson, and teacher and student communication
during a lesson.

This paper reports on a study that aims to address the challenges of UN Sustainable Development Goal 4 to ensure inclusive and equitable quality education for all. The study focuses on school mathematics in particular. With regard to ensuring equitable access to quality education, it is argued that there is a need to consider the epistemic quality of what students come to know, make sense of and be able to do in school mathematics. Accordingly, the aim is to maximize the chances that all pupils will have epistemic access to school mathematics of high epistemic quality. The study is based on the theoretical framework of Joint Action Theory in Didactics (JATD). Associated research questions focus on the quality of teacher-student(s) joint action and on the epistemic quality of the content. The paper draws on empirical research findings of the Developing Mathematical Thinking in the Primary Classroom (DMTPC) project (2010–12) and also on the findings of a parallel study of mathematics teachers’ assessment practices in Ghana. One teacher’s action research project is used as an exemplar to illustrate how mathematics can become more accessible and inclusive thus leading to an evolution in mathematical thinking and high-quality epistemic access for all. 相似文献
