To be genuine in artificial circumstances: evaluating the theatre analogy for understanding teachers’ workplace and work

This paper provides teachers and teacher educators with food for thought by developing a broad, contemporary re-evaluation of the often-used analogy between teaching and the theatre. It does so by synthesizing insights from scholarly works in education with insights from writing about theatre, including both historical work and published interviews with practicing stage actors. This approach throws into relief particular ways in which teaching does and does not resemble acting as described by its present-day practitioners. A key parallel is observed between the central challenges faced by teachers and actors: acting requires being truthful in imaginary circumstances, while teaching requires being genuine in artificial circumstances. Using work on bildung, the nature of this challenge is examined, and a call is made to help teachers and students better appreciate the intimate, reciprocal and shared nature of good teaching – a challenge in a culture where corporate interests aggressively promote personalized and “anytime, anywhere” learning. The paper also addresses the phenomenon of massive online courses, which enthusiasts like to believe teach themselves. This idea, I suggest, is as absurd as the notion that a great theatre building could obviate the need for a strong cast. .

Post-secondary Science Students’ Explanations of <Emphasis Type="Italic">Randomness</Emphasis> and <Emphasis Type="Italic">Variation</Emphasis> and Implications for Science Learning

The concepts of randomness and variation are pervasive in science. The purpose of this study was to document how post-secondary life science students explain randomness and variation, infer relationships between their explanations, and ability to describe and identify appropriate and inappropriate variation, and determine if students can identify sources of variation. An instrument designed to test statistical concepts was administered to 282 college students from three universities, ranging from introductory non-science majors to science graduate students. Students readily distinguished between causes of variation. A naïve no-pattern concept of randomness persisted from first-year non-science majors to senior-level science majors, contributing to incorrect responses on the variation instrument. Students’ expressions of randomness were better predictors of performance on the variation instrument than their expressions of variation. It is argued that inclusion of everyday language uses of randomness in instruction can bridge the gap between vernacular and scientific uses of this term.

中国大陆高等工程教育专业认证的发展历程与展望

中国大陆高等工程教育专业认证经历了热烈的筹备、良好的开局、漫长的探索三个阶段。总体来看,我国大陆地区高等工程教育专业认证发展缓慢。究其原因,主要在于理论研究滞后、顶层设计重心偏移、认证机构缺乏、专业认证与工程师注册制度脱节等。在此基础上,本文展望了中国大陆高等工程教育专业认证的发展趋势。     

基于模糊自适应变权重的经济时间序列组合预测模型研究

组合方法首先选取支持向量机预测算法和一阶指数平滑法对经济时间序列分别进行预测,来建立模糊自适应变权重组合预测模型。为对比模糊自适应变权重的经济时间序列组合预测模型的预测效果,选取了两种定值加权组合预测模型:平均加权模型、误差平方和最小组合预测模型。通过实验比较分析:模糊自适应变权重组合预测可以综合利用各单项预测方法的优点,比单一模型预测结果精度有了很大提高,且优于定值加权组合预测,在经济时间序列的预测方面有较高的应用价值。

Establishing respectful educative relationships: a study of newly qualified teachers in Ireland

Interpersonal respect is a fundamental aspect of relating to others. This is especially true for teachers, as cultivating relationships is implicit in effective teaching. This three-year qualitative study examines a developing understanding of respect for pre-service teachers that progresses on to their first year’s teaching to examine the influential factors on that understanding. These teachers’ pupils were also asked to comment on their perceptions of respect. The findings indicate that interpersonal respect in an educative relationship is influenced by the level of autonomy afforded pupils and minimising the power differential between teachers and pupils.
