体育课程实施中的异变问题研究

为推动我国体育课程实施理论与实践的发展，采用文献资料法等研究方法，对体育课程实施中的“异变”问题进行初步探讨。研究认为：对体育课程实施问题的研究尚未引起体育学界的足够重视；体育课程在实施中发生“异变”有其必然性，根据其正负效应可分为超越性异变与衰退性异变两种类型：导致体育课程实施产生“异变”的因素是多方而的；住体育课程的实施中应采取措施趋利避害，以促进超越性异变。

A review of ancient Egyptian pigments and cosmetics

The pigments used by the ancient Egyptians constitute the most diverse pigment palette of the ancient world. This review discusses the pigments and binders which were used, arranged principally in terms of the colours themselves, namely, the white, green, grey, black, brown, blue, red, orange, and yellow pigments. The chemical identity of these pigments is discussed with some details regarding the artefacts or time periods from which the pigment concerned has been identified. Combinations of pigments were used for creating some colours, especially: greens, pinks, blues, yellows, and a variety of pale hues by mixing primary colours with a white addition, such as calcite. The identification of ancient Egyptian pigments is often aggravated by chemical interactions between pigment and binder media, or between the pigment and environmental pollutants, or both. The nature of the binders and varnishes used in ancient Egypt is briefly discussed. The identification of green pigments from ancient Egypt is often difficult, and some of the recent research concerning the topic is reviewed. In addition to including relevant details from older literature, this review provides a synopsis of recent studies which have appeared since the last major review carried out by Lee and Quirke in 2000.

康托对角线法真的证明实数不可数了吗?

首先揭示,康托对角线法的使用存在一个隐含前提。如改变前提,是可以得到连续统与自然数集合间的一个一一对应的。这一结论,与传统看法明显不同,而由此,连续统假设的相对独立性将是必然的,从而为这一问题的澄清提供了依据。     

谈“辩”论“当”——墨家辩学与现代论辩理论

墨家辩学是我国古代名辩理论的主要部分。根据墨家辩学中的有关知识,联系现代论辩理论中的“承认”说,可以得到一种认识:进行论辩是为了“争胜”;要能“争胜”,就要注意在论辩中“取当”;所谓“取当”,也就是要注意在论辩过程中谋求“承认”。     

英语中动句中的NP移位

一直以来语言学界对英语中动词有着诸多争议,因此有必要换个视角对其进行作进一步的探讨。现以宋国明的研究为基础,尝试利用约束理论、题元准则和格理论等已有概念来解释中动句中的NP移位,并通过例子证明中动词带内外双主目的观点能在生成语法框架内得到很合理的解释。     

Undergraduates and the development of argument

This article emphasizes the need to encourage undergraduate students to develop arguments, which involves enhancing their analytical skills and capacity for critical thinking, across disciplines regardless of level. It argues that these skills, required by the Quality Assurance Agency＇s （QAA） benchmarks, are developed not by instruction but by engaging with the philosophic process that leads to the deep learning. This process of learning is based on a dialectical approach, viewing dialogue with colleagues, primary texts and written assignments, as central to developing an inductive argument and a critical perspective. This article proposes an analytical framework to analyze the extent to which a tutor is facilitating the development of argument. It suggests that while, if required one must provide students with explicit guidelines about this process, nevertheless this practice is problematic because of the inherent tension between explicit teaching and deep learning, which facilitates the acquisition of these analytical skills.
