Managing Endings in a Longitudinal Study: Respect for Persons

In this paper I describe and discuss the way that a book I had written on a five-year longitudinal study of school science teaching was received by the pupils and teachers it featured. By and large the pupils’ reception was positive. However, one group of teachers was deeply hurt by the book. I trace this mainly to my failure to consider adequately their fears of the consequences of the book’s publication and possibly to my failure to consider with them the psychological significance of my withdrawing from the school after five years of regular study. I hope that there are lessons not only for myself but also for others considering longitudinal and ethnographic research in science education and more broadly.     

论概念段作为科技英语的翻译单位

概念段是阐述一个完整思想概念的语段，概念段分为简单概念段与复杂概念段。语义、英汉语言各自特点、修辞功能及修辞技巧决定着概念段应该作为科技英语的翻译单位。译好概念段必须抓住概念段的主题，理顺其内在的逻辑关系。以概念段为科技英语的翻译单位能使译文从整体意义上与原文等效。     

基于学习进阶的物理单元学习过程设计

单元学习过程设计是单元教学设计的重要组成部分,是在单元教学内容分析和学情分析的基础上,为了实现单元学习目标而把一系列由简单到复杂、由浅入深的学习事件组织起来的系统规划。基于学习进阶设计单元学习过程包括大概念与大思路的形成、学习方式转变等。单元学习过程设计应建构学习进阶假设,从整体上规划学生核心素养的发展。

Some Reflections On Contemporary Canadian Catholic Education

Increasingly, Canadian Catholic education is identified according to theological and denominational distinctiveness. In the past, however, Catholic education was grounded upon an unambiguous philosophy of education, one that recognized education and teaching as primarily philosophical activities. Today, there is a noticeable absence of an identifiable Catholic philosophy of education, an absence that is particularly conspicuous in the pluralist and multi-faith makeup of Canada. In such a context, relying upon theological distinctiveness is insufficient. What is unique about Catholic education? What are some of the reasons that have led to the abandoning of a distinctively Catholic philosophy of education? Can such an education defend itself without identifying its unique philosophical and pedagogical principles? These, among others, are some of questions and issues of this paper.
