The London Association for the Teaching of English is a subject group that was founded in 1947 to ‘provide a live forum for the exchange of ideas, and to undertake the practical study of problems connected with the teaching of English’. The early history of this Association, its influence on the development of English pedagogy and practice is the subject of my current PhD research. Within this work are key questions about the nature of subject English, the curriculum, and the ways in which members of a subject community work together to effect change. This article gives some background to the research project, and begins to point towards some potentially important questions about the subject and ways of working together. After two decades of top down, centralised government initiatives around English pedagogy, curriculum and assessment, and teachers’ professional development, these questions are worth addressing. 相似文献

在新课程理念下,教学过程本身在本质上已经发生了重大变化,教学过程追求的是一种对话、沟通、理解和创新.体育课的教学必须在新的体育教学观念的指导下,树立"健康第一"的教学设计理念,创设多元化的教学环境,努力体现对学生智力、体力、情感以及创新精神和实践能力的培养,调动学生的内在因素,促进其全面发展,可持续性发展. 相似文献

This article suggests a device that counselors may use as a reference for bridging the gap between counseling theory and technique. Cognitive development theory provides the basis for understanding a single transaction between counselor and client. The acronyms FACTS and CRACKS suggest the structural dynamics taking place within the client's cognitive field as the counselor performs in two different stages of the counseling process. 相似文献

Abstract Learning by doing may not be the most effective strategy for teaching environmental problem-solving skills. A survey of Michigan educators indicates that of the teaching strategies listed, case studies and talking about what others do to solve environmental problems are the most important. The implications of building familiarity with environmental issues and solutions from a variety of examples are discussed, and an explanation for the reported low success of classroom action projects is presented. 相似文献

This design experiment in prayer education for Jewish students was motivated by a current educational concern: educating for spirituality and religious practice. Educators are tasked with formally nurturing spirituality (Wright 2001). It is known that attitude to religious observance may change during adolescence (Hyde 1963), thus attitude to prayer needs attention. The effects/consequences of prayer understanding reach beyond religious practice itself, to encompass issues of faith, identity, spiritual development and well-being (Sigel 2009). Here quantitative and qualitative analysis is used to measure the effects of a tefillah (prayer and its understanding) course on student attitudes to prayer. 相似文献

增值税具有公平税负、稳定财政收入及促进资本形成等优点，在其产生后的几十年里迅速风靡全球。令人关注的是，美国至今尚未引进增值税，其原因主要集中在两个方面：一是担心增值税的局限性会产生消极后果，如累退效应产生不公平，税负归宿不稳定，税负转嫁可能引起通货膨胀；但是深层的原因是政治上的障碍，立法担心增值税的引入会引起中央和地方在税收主权和利益方面的冲突。 相似文献
