运用知识建构圈促进学生课堂深度互动研究

课堂话语是促进学生参与课堂互动的核心要素之一,而现有的课堂话语体系多是围绕教师展开的"师生对话"或是被少数"话霸"主导的"生生对话",缺乏全员互动的"广度"与探究的"深度"。该文以南京市某小学四年一班学生为研究对象,采用准实验方法和基于设计的研究方法相结合的方式,根据知识建构理论利用知识建构圈教学策略开展了为期12周的教学实践。教学实践中通过更改教室座椅布局、调整知识建构圈中师生位次、建立会话规则、明确协商机制以及整合教学内容等教学手段进行多次教学迭代,尝试改进课堂互动效果。在将全程班级课堂互动录像转录为文本的基础上,根据知识深度模型、问题解释深度量表对其编码并进行语义分析。结果表明:采用知识建构圈教学策略能有效的提升学生互动的参与度以及提出问题的"量"与"质";能推进学生互动的"广度"与"深度";能提高学生的言语表达能力和人际交往能力,初步实现了课堂由"浅层"互动向"深层"互动的转变。     

Photoshop“抠图”的学习情境设计——基于工作过程的教学设计

基于工作过程的教学设计提出了教学的三要素：学生、教师、情境。教学应该是学生主动参与、教师根据学生的主动存在及其出现的情况做出适当的反应。基于工作过程的教学设计,强调的是针对行动顺序的每一个工作环节,传授相关课程内容,实现实践技能与理论知识的整合,知识的总量未变,知识排序的方式发生了变化。     

国外DBL设计型学习的研究及其对我国物理教学的启示

设计型学习是让学生结合已有的知识,围绕确定的问题和设定的规则设计产品或者方案的教学方法,在实施的过程中教师根据学生的自身情况,促进学生不断学习新的知识,从而对方案或者产品进行不断的改进.本文主要对国外设计型学习的5个研究主题(设计型学习教学实践探索、特征研究、课堂环境要求、教师角色定位以及教学评价机制)进行介绍和评述,并提出对我国物理教学3个方面的启示,呼吁学者们更多的关注设计型学习的实证研究.

基于设计的研究:教育研究范式的创新

基于设计的研究是为了应对知识经济社会对教育研究的挑战而发展出的一种新范式。它充分尊重教育的特殊性,认为教育是一种基于真实情境而客观存在的复杂活动;它高度关注基于实践情境的知识建构,主张知识通过建构而生成,但必须经受不同情境的检验才具有客观性和可信性;它混合定量研究与定性研究,强调通过迭代循环的限定推理来揭示学习的发生机制和变化轨迹。     

基于设计的合作性行动研究的理念与实践——以基于学生发展的校本研究实验为例

论TPACK视域下专家型教师培养模式的转变

伴随着技术增强型社会的到来,传统的专家型教师培养已不能适应教育信息化向纵深发展和教育教学改革深入推进的需要。文章从传统专家型教师培养的特征和存在问题出发,引入了TPACK概念框架,为专家型教师的培养提供了新的理论指导:显性知识与隐性知识相结合的课程设置;在经验反思的基础上,立足于真实问题情境中的校本培训;基于设计的研究导向下的校本教研超越了行动研究中单纯的实践问题解决取向。     

基于项目的英语词汇教学方式研究

探索复习课教学主线设计 提高科学课堂的实效性

复习课是初中科学课堂的重要课型之一,是教师指导学生温习知识,强化知识,加深理解,使知识系统化并进行重新再建构的过程。然而,在课堂实践中,教师往往只注重知识点的简单回顾,而缺少对知识间联系的探究;只注重解几道题,而缺少方法的梳理;只注重知识本身,而缺少与实际生活的联系,使课堂显得沉闷,学生缺乏主动参与,也缺乏知识的灵活应用,导致复习效果不太理想,也无法促进学生的发展。有实效性的课堂一般都有较好的教学主线,有利于突出重点,把握内容和方法,让学生乐于参与。其中,基于问题解决、方法梳理、知识建构这三种方法是常见的主线构建模式,通过日常课堂观摩和教学实践,发现上述三种模式确实有利于提升课堂实效。     

The relationships between social participatory roles and cognitive engagement levels in online discussions

Understanding the relationship between social interaction patterns and cognitive engagement levels has critical implications on collaborative learning theory, pedagogy, and technology. This study used a multi-method approach to examine the relationship between students' social participatory roles and cognitive engagement levels within asynchronous online discussions. Results showed that students' social participatory role was a critical indicator of cognitive engagement level. Socially active students made more cognitive contributions to knowledge inquiry and knowledge construction. But there were exceptions: after taking leadership roles (i.e., discussion designers and facilitators), some students moved from peripheral participation to active participation. Second, there was a progressive development process: individual students' deep-level knowledge inquiry could trigger peer interaction, which could further advance group knowledge construction. Third, students had a tendency to keeping social-cognitive engagement patterns throughout discussions. Based on the result, this study proposed implications for collaborative learning theory, pedagogy support, and tool development.     

The Spectrum of Dynamic Inquiry Teaching Practices

The Israeli high school biology curriculum comprises the Biomind program, in which students are engaged in an open inquiry learning process. The dynamic features of open inquiry often pose challenges to teachers in implementing the Biomind program. The current qualitative research shows that facilitating students in a dynamic open inquiry process is multidimensional. Teaching practices cover a wide range of methods, from structured inquiry through guided inquiry to open inquiry. An individual teacher’s profile can be elucidated on the basis of this spectrum. In addition, we realised that teachers often encounter several difficulties in implementing open dynamic inquiry: A dearth of teachers’ scientific knowledge, students’ lack of scientific knowledge and skills, and a restrictive time-frame. This study suggests several areas which should be considered while implementing an on going professional development support for teachers who are engaged in open inquiry teaching.     

Knowledge construction among teachers within a community based on inquiry as stance

This study explores the process of teachers' knowledge construction within a community designed based on the concept of inquiry as stance. Through close examination of three teachers' activities, the study investigates how teachers adapt and respond to such a community, whether their inquiry actually generates knowledge, and how it relates to their teaching practice. The findings demonstrate that inquiry as stance can serve as a framework for understanding how teachers can generate knowledge. However, the study contends that effort must be made if teachers are to assume an inquiry stance within their communities.     

Emergence of Progressive-Inquiry Culture in Computer-Supported Collaborative Learning

The study focused on analysing the emergence of a progressive-inquiry culture in two CSILE (Computer-Supported Intentional Learning Environment) classrooms across a three-year period. A principal feature of this kind of culture is the processing of explanatory knowledge instead of merely factual knowledge. The results of the study indicate that the classroom culture changed over the three years following the introduction of CSILE. The explanatory level of knowledge produced by the students became increasingly deeper in tracking from the first to third year. In one of the classrooms, the children's levels of explanation reached substantial depth as we pass from year 1 to year 3; here the difference on this temporal variable was large and significant. In this classroom, the students' inquiry was more and more explicitly focused on construction of their own intuitive explanations, as well as the search for explanatory scientific information. Progress in inquiry culture emerged only through the teacher's extended efforts to expand students' practices of progressive inquiry.

对物理探究式教学的几点思考

探究式教学是指为培养学生的探究意识及实践创新能力,教师创建条件引导学生主动探究问题、自主建构其知识体系的一种教学方式。在实践中发现,物理探究式教学有形式化与泛化现象,学生可能出现思维障碍,教师需要重建角色、更新知识结构、创新教学过程。作为应对策略,要注意营造民主、宽松、和睦的教学氛围,探究活动的设计要符合学生和教学的客观实际,要注重对学生探究能力的培养和强调合作学习。

科学探究的本质特征——兼论科学探究与实验探究的关系

科学探究不单是实验探究,它不仅具有外显的可操作的实践性特征,更伴随着内隐的深刻的思维活动过程,即具有思维活动的认识性特征。科学探究的本质特征在于：科学探究是探究者在对未知领域进行认知时的一种有效的认识和实践方式;科学探究过程是一个知识建构过程;科学探究离不开科学思维。     

Peer inquiry: Discovering what you know through dialogue

The article discusses a dialogical peer inquiry process as a practice of co-constructing knowledge in graduate coursework. The process, formerly structured as an exam, was developed by Dr. Vera John-Steiner more than 30 years ago and has been implemented in adapted forms by her students in their teaching. The dialogical peer inquiry process involves collaborating creatively with peers in the co-construction of knowledge. The article discusses the underpinnings of the process and uses voices of students in a graduate art education course to illuminate the process and its meanings for students.
