教学监控能力:课堂教学中不容忽视的因素

教师的教学监控能力是决定课堂教学质量的主要因素,也是决定教师教学行为和教学效果的关键因素。教师的自我监控能力是课堂教学最终能否达到理想教学效果的保证。教师在课堂教学过程中除监控自己的教学和学生的学习行为外,还要对教学环节、课程建构、师生互动等要素进行全面的监控与协调。     

利用现代教学媒体整合物理课堂教学

21世纪的教育是全新的教育。伴随着信息技术的发展,课堂教学过程、教学观念和教育组织形式等各种教学因素的变革物理课堂教学逐渐走向现代化。新一轮基础教育课程改革带来了教育观念、教学组织形式的又一次革命。现代教学媒体全面渗入新一轮物理课程改革实践,势必改变教学方式和教学手段,提高物理教学效率。因此,在物理教学中,无论是过分地夸大现代教学媒体的作

课堂教学中有关教学媒体选择的博弈论分析

课堂教学中媒体的选择需要遵循一定的原则,但是在实践中教学媒体的选择往往由教师自身的能力和判断决定.使用媒体单一,针对性较差,应用博弈论的观点分析课堂教学中的媒体选择发现师生信息不对称、教师支付不足等原因引起媒体选择不科学、效用不高等问题,本文针对这些问题提出媒体选择中激励教师创新、以道德约束等实现均衡的建议.     

教学媒体在课堂教学中应用的分析

一、教学媒体综述 媒体是指承载、加工和传递信息的介质或工具。当某一媒体被用于教学目的时,则被称为教学媒体。一般地,从媒体的组成和使用方面把教学媒体分为传统媒体（黑板、挂图、模型、教具）、电教媒体（投影、录音、录像）及信息媒体（课件、视频、计算机、网络）等。

Connecting engagement and focus in pedagogic task design

Teachers of mathematics face a particular tension, which the authors call the planning paradox If teachers plan from objectives, the tasks they set are likely to be unrewarding for the pupils and mathematically impoverished. Planning from tasks may increase pupils' engagement but their activity is likely to be unfocused and learning difficult to assess. By seeking inspiration from research in the areas of curriculum design, the nature of authenticity in the classroom and the use of tools, and by looking retrospectively at the design of computer‐based tasks that have underpinned their research for many years, the authors recognise a theme of purposeful activity, leading to a planned appreciation of utilities for certain mathematical concepts. The authors propose utility as a third dimension of understanding, which can be linked to purpose in the effective design of tasks. The article concludes with a set of heuristics to guide such planning.

Extract from new understandings of teachers' pedagogic knowledge 1

Abstract

The focus of this article is a comparative review of the science curriculum for England and Wales from the perspective of recent developments in the United States of America, Australia, New Zealand and the Canadian province of Ontario. In the comparison of science curriculum documents and the language deployed, questions are raised about differences as well as commonalities among and between documents from various jurisdictions. Issues discussed include: the varying emphases upon science topics and/or intended learning outcomes; integration with other curriculum areas; the content and organization of the science curriculum; and ways of assessing students’ performances and understandings. The article draws attention to the importance of comparative analysis which informs our understanding of the effects of curriculum change, its relation to students’ achievements in science, and the need to support the development of teachers.

Innovative learning environments and new materialism: A conjunctural analysis of pedagogic spaces

Abstract

An Organisation for Economic Cooperation and Development research priority, innovative learning environments (ILEs) have been translated into policy and practice in 25 countries around the world. In Aotearoa/New Zealand, learning spaces are being reconceptualised in relation to this policy work by school leaders who are confronted by an impetus to lead pedagogic change. The article contributes a conjunctural analysis of the milieu around the redesign of these education facilities. Recognising that bodies and objects entwine in pedagogic spaces, we contribute a new materialism reading of ILEs as these are instantiated in New Zealand. New materialism recognises the agential nature of matter and questions the anthropocentric narrative that frames the post-enlightenment conception of what it means to be human. The decentring of human subjects through a materialist ontology facilitates a consideration of the power of objects to affect the spatial politics of learning environments. The article traces a relationship between the New Zealand strategic plan for Education 2015–2021 and principal conceptions of ILE as the lived spaces of this policy actualisation and the disciplinary/control society conjuncture. Informed by theories of spatial practice, we argue that principals’ understandings of ‘space’ are integral to pedagogic approaches within open-plan spaces. A conjunctural analysis can expand the capacity to act politically. By examining the complex conditions of a political intervention, in this case ILEs, we trace the displacements and condensations of different sorts of contradictions, and thus open up possibilities for action.     

A new heuristic for task scheduling in heterogeneous computing environment

Heterogeneous computing （HC） environment utilizes diverse resources with different computational capabilities to solve computing-intensive applications having diverse computational requirements and constraints. The task assignment problem in HC environment can be formally defined as for a given set of tasks and machines, assigning tasks to machines to achieve the minimum makespan. In this paper we propose a new task scheduling heuristic, high standard deviation first （HSTDF）, which considers the standard deviation of the expected execution time of a task as a selection criterion. Standard deviation of the expected execution time of a task represents the amount of variation in task execution time on different machines. Our conclusion is that tasks having high standard deviation must be assigned first for scheduling. A large number of experiments were carried out to check the effectiveness of the proposed heuristic in different scenarios, and the comparison with the existing heuristics （Max-min, Sufferage, Segmented Min-average, Segmented Min-min, and Segmented Max-min） clearly reveals that the proposed heuristic outperforms all existing heuristics in terms of average makespan.     

Teaching mathematics in/for new times: A poststructuralist analysis of the productive quality of the pedagogic process

Mathematics educators and researchers generally recognise the importance of students' active involvement in learning processes; this active engagement is positively thought of in relation to the development of understanding and the construction of mathematical knowledge. However, it is often not well understood, nor perhaps even considered, how engagement in these learning processes also produces the learner and his/her feelings of competence and confidence in/with mathematics. In this paper I undertake, from a post structuralist perspective, a meta-analysis of two short episodes from a paper by Manouchehri and Goodman (2000). I use these interactions to explore (a) how mathematical knowledge and identities are produced in teaching/learning interactions in the classroom and (b) the wider practical implications of this productive power ofprocess for mathematics education and research. Through analyses such as these it may be possible to breathe new life and purpose into mathematics education in the twenty-first century; not by negating what has come before, but in moving on to explore the exciting possibilities that present themselves when taken-for-granted assumptions of a rational, freely choosing proficient (NCTM, 2000) humanist subject are interrupted and revised.This revised version was published online in October 2005 with corrections to the Cover Date.
