Introduction: knowledge,ignorance, and relations of dominance

What we have come to understand as education has a temporal dimension: the school year, progression based on time, timetables, and so on. Similarly, our understanding of teaching is framed by temporality, primarily through salary structures and an implicit coupling of performance with time in the field. We argue that this underlying generative temporality is under revision. This revision is taking place through policy moves such as the professional standards agenda, which unlike salary structures (at least current ones) privilege demonstrable performance over tenure. Such a revision places time not as an external measure in which events and practices take place, but as the very core of such practices and events. Taking stimulus from the role of work-integrated learning within initial teacher education, we engage with this revision of temporality in education. With increasing attention being paid to temporality in scholarship across a number of disciplines, there has arguably never been a more appropriate opportunity to engage with the temporality of teaching.     

关于整系数多项式的一个结果

用简洁的方法，证明了如下结果：若整系数多项式f(x)=x^n a1x^n-1 a2x^n-2 …＋an-1x an的所有根的绝对值都不大于1，an≠0，则f(x)的根都是单位根。     

Maximizing modern distribution of complex anatomical spatial information: 3D reconstruction and rapid prototype production of anatomical corrosion casts of human specimens

Anatomical corrosion casts of human specimens are useful teaching aids. However, their use is limited due to ethical dilemmas associated with their production, their lack of perfect reproducibility, and their consumption of original specimens in the process of casting. In this study, new approaches with modern distribution of complex anatomical spatial information were explored to overcome these limitations through the digitalization of anatomical casts of human specimens through three‐dimensional (3D) reconstruction, rapid prototype production, and Web‐based 3D atlas construction. The corrosion cast of a lung, along with its associated arteries, veins, trachea, and bronchial tree was CT‐scanned, and the data was then processed by Mimics software. Data from the lung casts were then reconstructed into 3D models using a hybrid method, utilizing both “image threshold” and “region growing.” The fine structures of the bronchial tree, arterial, and venous network of the lung were clearly displayed and demonstrated their distinct relationships. The multiple divisions of bronchi and bronchopulmonary segments were identified. The 3D models were then uploaded into a rapid prototype 3D printer to physically duplicate the cast. The physically duplicated model of the lung was rescanned by CT and reconstructed to detect its production accuracy. Gross observation and accuracy detection were used to evaluate the duplication and few differences were found. Finally, Virtual Reality Modeling Language (VRML) was used to edit the 3D casting models to construct a Web‐based 3D atlas accessible through Internet Explorer with 3D display and annotation functions.

A case study of using an online community of practice for teachers’ professional development at a secondary school in China

In this case study, an online community was designed at a secondary school in China for the teachers to prepare their lessons collectively, reflect on their teaching practices, collect comments from peers, and share resources. A survey was administered to the teachers to investigate their perceptions on the online community for their professional development. Two hundred and eighty-three teachers responded to the survey and eight teachers were further interviewed by email. The result showed that most teachers liked using the online community as they could gain subject knowledge and could obtain support from peers, share experiences and get feedback, and exchange resources. Also, online entries confirmed that transformational changes in teaching pedagogy and students’ learning activities occurred along the time. However, certain teachers did not participate in the online community frequently. This paper describes the context of the case study, design dimensions of the online community, teachers’ positive perceptions on using the online community, and transformational changes. Also, strategies for promoting effective use of the online community are discussed and follow-up studies to address the challenges involved in this study are proposed.

中古汉语程度副词初探

中古汉语程度副词有单音词和复音词之分。它们既有继承上古汉语而来的程度副词,又有不少中古时期新兴的成员。继承而来的程度副词和新兴成员在构词方式、使用特点上呈现出不同的特征。此外,本文还对中古汉语程度副词的发展特点进行了探讨。     

当前素质教育中若干问题的思考

我国当前素质教育实践中存在轰轰烈烈素质教育和扎扎实实的应试教育的矛盾、自然科学和人文社会科学教育、知识教育和道德教育相脱离的矛盾、素质教育与社会环境不配套等一系列矛盾。素质教育是一个社会性的系统工程,需要全社会各方的关心和参与才能正确开展。解决这些矛盾需要教育理论创新、制度和政策创新与人事制度改革等一系列的创新和改革。
