儿童剧原创乏力探因

一、儿童剧教育未获重视中小学校忽视戏剧教育,这在当下表现得十分明显。重升学率、轻素质教育是其根脉,但教育传统中对戏剧的轻视也不容忽视。一直以来,儿童剧仅被视为学校思想政治教育的工具,其陶冶情操、培养艺术素养的社会功能被有意无意地忽视。许多农村中小学校教师甚至认为,儿童剧是属于表演性质     

课堂因和谐而高效

现代生理学和心理学研究表明,人脑可分为动力部分和工作部分两部分,两者不能互相取代．学生只有具备了较强的学习动力才能主动、勤奋地学习．《学记》一书说过：“安其学而亲其师,乐其友而信其道,是以虽离师辅而不反．”这古老而又永恒的教育箴言启示我们要在教育教学过程中让学生“亲其师”,就是把师生情感内化为一种学习的动力,然后期待产生“信其道”的学习实践结果．     

以色列教育勃兴之因

石崇巨富探因

在古往今来的富豪中,西晋青州人石崇是赫赫有名的。与强调石崇的奢侈生活相比,探讨他的巨额财产来源是一个更有价值的问题。石崇在平吴之役中贪污和其后得到的赏赐应该是其巨额家财的起点;在荆州当剌史时劫略商旅应该是其巨额家财的发展;而石崇经营具有营利性庄园是其巨额财富扩大的最大可能。

田舜年的历史思想探因

从历史记载来看,田舜年不仅是一位功绩显赫的司主,而且在文化方面,尤其是史学上取得了丰硕的成就。虽然大多数著作已不存世,但其作品中人、天、民的历史思想及其成因值得我们探讨。本文试图从作者的时代背景、家族和个人经历,以及所处的人文自然环境进行剖析,以明了其历史思想的形成原因,进而指出政治功用性和民族性是其思想的两大特点。

是果非因也

2013年新课标卷历史试题第27题：清代有学者说：“古有儒、释、道三教，自明以来，又多一教，日小说……士大夫、农、工、商贾，无不习闻之，以至儿童、妇女不识字者，亦皆闻而如见之，是其教较之儒、释、道而更广也。”这表明     

Primary humanities: a perspective from Wales

ABSTRACT

How the humanities subjects are represented in primary schools in Wales has been influenced by curriculum developments including Curriculum Cymraeg, the Skills Framework and the Foundation Phase. A central tenet of Welsh Government policy has been to actively encourage schools to promote a sense of ‘Welshness’ through curriculum content, pedagogies and school policies. In addition, early years’ education has been extended to 5–7-year olds and at Key Stage 2 skills and competencies are priorities, with subject content providing the context for learning. In 2015, the Donaldson Review’s recommendations were fully implemented in the Government’s plans for a new 3–16 Curriculum for Wales to be fully implemented by 2021. Humanities became one of six Areas of Learning and Experience (AoLE) with the curriculum content to be developed by an all-Wales partnership team which includes the Pioneer Schools’ network. This article traces the post devolution build-up to this latest ‘radical change’. It suggests that for stakeholders developing the humanities curriculum the challenge will be considering how the key concepts of different ‘subject pedagogies’ are represented, while fulfilling the Government’s emphasis on early years’ pedagogy and its focus on a competency-led curriculum.     

Teaching Cultural History from Primary Events

This article explores the relationship between specific cultural events such as Galileo’s work with the pendulum and a curriculum design that seeks to establish in skeletal form a comprehensive epic narrative about the co-evolution of cultural systems and human consciousness. The article explores some of the challenges and some of the strategies needed to represent complex primary events in the concise, viscerally immediate form necessary to make this curriculum offering practical.

山西省沙棘品种AFLP的初步分析

沙棘体内酚类物质和蛋白质含量较高,影响了基因组DNA提取的产量。采用改良CTAB法对观光木基因组DNA进行提取,经过紫外吸收、琼脂糖凝胶电泳、双酶切和AFLP标记检测,结果表明:改良CTAB法提取的基因组DNA吸光值OD260/OD280为1.7～1.9,DNA无降解现象和杂质污染;基因组DNA双酶切彻底,并且APLP扩增的条带较多而且清晰。从而建立了适合沙棘AFLP分子标记的反应体系,为利用AFLP标记对沙棘进行分子生物学研究及分子育种奠定了基础。

Primary science education: Views from three Australian States

This paper reports an empirical study of science education in Australian primary schools. The data show that, while funding is seen as a major determinant of what is taught and how it is taught, teacher-confidence and teacher-knowledge are also important variables. Teachers are most confident with topics drawn from the biological sciences, particularly things to do with plants. With this exception there is no shared body of science education knowledge that could be used to develop a curriculum for science education. There was evidence that most teachers see a need for a hands-on approach to primary science education involving the use of concrete materials. A substantial proportion of teachers agree that some of the problems would be alleviated by having a set course together with simple, prepared kits containing sample learning experiences. Any such materials must make provision for individual teachers to capitalise on critical teaching incidents as they arise and must not undermine the professional pride that teachers have in their work.

Enhancing Transition from Early Childhood Phase to Primary Education: Evidence from the research literature

There are many levels in the educational continuum, and each time a child moves from one level to the other transition occurs. Transition from the early childhood phase to primary school is one of the major steps that each child has to take in the education continuum, and has been known to be traumatic for most children. There is also research evidence which contends that this transition to the first year of primary school is very important for the child's future physical, emotional and intellectual development. This article examines the literature on transition to school, and discusses its importance and the need to minimise its adverse effects by providing a smooth transition for the child. The article presents the factors which impact on successful transition from the early childhood phase to primary school.
