The emergence and institutional co-determination of sustainability as a teaching topic in interdisciplinary science teacher education

This paper takes an institutional perspective on the topic of sustainability in order to analyse how this ‘idea’ enters science teacher education through an interdisciplinary approach. It shows how the development and implementation of a course for Danish pre-service teachers was conditioned and constrained by a complex web of interactions in and among the teaching disciplines of biology, geography and physics/chemistry and among the institutions of school, teacher college and university. The data collected are used to identify influences among the disciplines as well as disciplinary differences, conceptualised through a new reference model that separates the analysis from the usual sustainability dimensions. The findings reveal how sustainability as a teaching topic can be a unifying idea in an interdisciplinary setting. Disciplinary differences evidently impact course planning and implementation significantly, but not exclusively. By elaborating on the interactions between these circumstances, the paper provides insight into the processes of developing interdisciplinary teacher education.     

刀具半径补偿指令在数控机床上编程中的应用

试论国内非教育网站资源的教学价值

本文以非教育网站资源为研究对象,系统分析和总结了非教育网站资源的教学价值。教育网站资源很容易被用于教育教学中,而非教育网站资源的教学价值往往容易受到忽视,其实非教育网站资源具有目标受众广泛、分布离散性、价值潜在性的特点,并在优化教学、学生的个性发展、对师生的人文关怀、批判思维的培养方面具有独特的教学价值。     

Metaphor——A Tool for Writing

Figurative speeches, especially metaphors that prevail essays, novels, reports, poems, etc. give flavor, if not life, to writings, help express the inexpressible, bring the abstract concrete, make the tedious succinct, and illuminate the vague and the ambiguous bright and clear. It seems that metaphors to writing is what salt to cooking ─ and more. In this paper, we are attempting to drag it to a "down-to-earth" tool to be handy to common learners by quoting examples from various styles to show how it can be used to increase language power and how important it is for ordinary Chinese learners of English to get familiar with and learn to employ metaphors and other figurative speeches in writing. We should be able to use words in non-literal sense to lend force to an idea, to heighten effects, or to create atmosphere, so as to make our writings eligible at least for practical use and readable for an ordinary native speaker of English.

Ultrasonic tomography and its applications in oilfield

INTRODUCTION Oil and water well is an important basic estab- lishment in oilfields. In many oilfields, there are many different damages in the well’s casing walls after its development for a period of time. They will affect the normal production of damaged wells and adversely influence the neighbouring wells and the block, and threaten steady production. There are different kinds of damages due to multiple problems in the casing walls, for example, corrosion, perforation, decreased diame…     

Exit cards: creating a dialogue for continuous evaluation

This study explored the use of Exit Cards, which are formative evaluations of student knowledge and instruction undertaken at every class meeting. Its results are based on Exit Card data from two undergraduate research methods courses. Thematic analysis indicated that students used Exit Cards to communicate (1) what they learned, (2) challenges with course material, (3) experiences with peers, (4) requests for help, (5) challenges with coping, and (6) successes. While the present study is an initial exploration of the use of Exit Cards, it contributes to knowledge on the utilization of informal formative assessments.
