计算机投影教学及其教学方法

采取投影的方式用多媒体计算机上课是适应现代教学改革的一个新的教学手段。它将计算机的特有功能用于教学,通过计算机的使用,把教学内容、教学经验融为一体,弥补了传统教学方式的不足,充分发挥了教学工具的功能,给教学的发挥带来了广阔的空间。这种教学方式打破了学生呆板的线性思维的学习方式,易于突出学习重点,加深学生对知识点的印象,适合于课堂中的创新教育,便于对学生的素质培养,能充分调动学生的学习积极性,提高他们的学习效率。     

Promoting historical contextualization: the development and testing of a pedagogy

The aim of this explorative study was to develop and test a pedagogy aimed at promoting students’ ability to perform historical contextualization. Teaching historical contextualization was conceptualized in terms of four pedagogical design principles: (1) making students aware of the consequences of a present-oriented perspective when examining the past, (2) enhancing the reconstruction of a historical context, (3) enhancing the use of the historical context to explain historical phenomena and (4) enhancing historical empathy. The effectiveness of these principles was explored in a lesson unit focusing on the seventeenth and eighteenth centuries. In a quasi-experimental pre-test–post-test design with experimental and control conditions, the effects of the pedagogy on 15- and 16-year-old students’ ability to perform historical contextualization were examined (n = 131). The results indicated that students in the experimental condition significantly improved their ability to perform historical contextualization compared to students in the control condition. These findings could be used to help teachers and other educational professionals design and implement historical contextualization tasks and instructions.

The efficacy of `whole word' versus `analytic' reading instruction for children with Down syndrome

An intervention study was conducted toinvestigate whether children with Down syndrome(DS) would benefit from an `analytic' approachto reading instruction, which encompassedexplicit training in phonological awareness.Participants were seven English-speakingchildren with DS aged 8;6 (years;months) to11;1, who demonstrated little or nononword-reading ability prior to intervention.The children received weekly instruction (forsix weeks) in reading aloud 30 regularly speltmonosyllables (e.g., ten, bake) using an`analytic' approach, in which words werelearned by combining onsets with rimes (fourchildren), or a `whole-word' approach (threechildren). Participants' oral reading wasassessed pre- and post-intervention using areading test comprising the 30 trained wordsand 30 untrained (generalisation) words. Mostchildren (six out of seven) read more trainingwords correctly after intervention than before,with significant improvement shown by fourchildren (two trained analytically, and twotrained with whole words). More importantly,reading of generalisation words improvedsignificantly in only three children, all ofwhom had received analytic training. It wasconcluded that children with DS benefit from ananalytic approach to reading instruction, eventhough their auditory-verbal memory (assessedusing digit span) is poor.     

研究性学习在中学数学教学中的体现与应用探析

广义研究性学习既是一种学习观,又是一种课程观.中学数学教学中的研究性学习,实质是在社会建构主义教育观下,学生自主学习数学知识并形成能力的过程.研究性学习并不是否定接受式学习与讲授式教学.作为一种学习观,研究性学习体现了“学生为本、学生发展为本、发展学生创新能力为本”的教学理念.     

简论课堂小组合作学习的实施策略

课堂教学要实现从"对知识的传授和讲解"向"对能力的培养"的转变,其途径之一就是让学生开展课堂合作式学习,使教学成为师-生、生-生互动交往的过程,让学生在积极参与小组学习活动的过程中学会学习、学会合作。课堂小组合作学习的实施策略是:合理分组、教师担当好学习促进者的角色以及建立科学的小组合作学习评价机制。
