Developing Rich Media-based Materials for Practice-based Teacher Education

这项为期4年的研究和开发项目名为“为基于实践的教师教育开发基于富媒体的材料”，其前提是，最近的技术发展使得以新的方式表现课堂作业成为可能。除了观看课堂互动的录制视频或阅读书面案例外，教师教育者和教师现在还可以观看动画和图像序列，这些动画和图像序列是用卡通人物实现的，用来描述在数学课堂中发生的或可能发生的活动。此外，教师教育者和教师可以通过在课堂互动中对学生或教师的替代动作进行自己的描述来对这些动画或图像序列做出反应。所有这些都可以在基于云的在线环境中进行，该环境还支持讨论论坛、问卷调查以及与学习管理系统相关的各种功能。这些技术为教师教育工作者提供了重要的支持，他们寻求为候选人提供基于课程的经验，强调基于实践的技能的发展。该项目的重点是数学教师教育。马里兰大学数学教育中心和密歇根大学的这个联合项目将生产6到8个实地测试模块，用于不同的课程，这些课程是数学教师准备计划的一部分。以下两方面的研究问题将得到解决：模块和环境的支持和约束是什么：(1)基于实践的教师教育和(2)向混合式教师教育的转变？该项目包括以下活动：(1)教师教育材料开发部分；（二）相关评价内容；(3)两个研究组成部分。开发阶段旨在开发LessonSketch.org平台和6到8个数学教师教育模块，用于全国各地的职前教师教育项目。这些模块的编写将考虑到以实践为基础的教师教育目标，并将利用LessonSketch.org平台的能力，作为对职前教师候选人使用富媒体教学工件的工具。教师教育研究与发展研究员将通过竞争性申请程序选出。他们将与同事团队一起开发各自的模块，这些团队将被招募组成他们的调查小组并试点模块活动。评估活动将集中在项目的材料开发方面。LessonSketch平台将收集数据，包括对研究员及其团队的采访、模块作者的观点、模块使用情况的描述性统计数据，以及教师教育者和职前教师最终用户对其体验质量的反馈。该项目的第一个研究活动是设计研究对基于实践的教师教育有用的各种技术基础设施。pi将确定教师教育工作者需要的工具，并希望超越当前基于网络的支持富媒体使用的能力，并将在LessonSketch环境中生成原型工具以满足这些需求。该项目的第二项研究活动将通过详细审查两个模块的执行情况来补充评价活动。这方面的研究将检查预期课程的目标，媒体使用的拟议模式，实施课程的保真度，以及职前教师所产生的学习。这项研究活动将有助于该领域了解，通过在线访问富媒体来中介的基于实践的教师教育在多大程度上是一种可以很容易地融入现有教师教育结构的实践。该项目将产生6至8个LessonSketch模块，用于教师教育课程。每个模块将在全国至少8个教师教育课程中实施，这意味着720至960名职前教师候选人将学习这些材料。该项目旨在通过支持大学课程实施课堂驱动的活动，将该领域转向以实践为基础的教师教育，这些活动将培养具有有效和有意义的数学教学能力的数学教师。

The 4-year research and development project, Developing Rich Media-based Materials for Practice-based Teacher Education, is premised on the notion that recent technological developments have made it feasible to represent classroom work in new ways. In addition to watching recorded videos of classroom interactions or reading written cases, teacher educators and teachers can now watch animations and image sequences, realized with cartoon characters, and made to depict activities that happened, or could have happened, in a mathematics classroom. Furthermore, teacher educators and teachers can react to such animations or image sequences by making their own depictions of alternative moves by students or teachers in classroom interaction. And all of that can take place in an on-line, cloud-based environment that also supports discussion fora, questionnaires, and the kinds of capabilities associated with learning management systems. Such technologies offer important affordances to teacher educators seeking to provide candidates with course-based experiences that emphasize the development of practice-based skills. The focus of the project is on mathematics teacher education. This joint project of the University of Maryland Center for Mathematics Education and the University of Michigan will produce 6 to 8 field-tested modules for use in different courses that are a part of mathematics teacher preparation programs. The following two-pronged research question will be resolved: What are the affordances and constraints of the modules and the environment as supports for: (1) practice based teacher education and (2) a shift toward blended teacher education?The project involves the following activities: (1) a teacher education materials development component; (2) a related evaluation component; and (3) two research components. The development phase seeks to develop both the LessonSketch.org platform and six to eight mathematics teacher education modules for use in preservice teacher education programs from around the country. The modules will be written with practice-based teacher education goals in mind and will use the capacities of the LessonSketch.org platform as a vehicle for using rich-media artifacts of teaching with preservice teacher candidates. LessonSketch Teacher Education Research and Development Fellows will be chosen through a competitive application process. They will develop their respective modules along with teams of colleagues that will be recruited to form their inquiry group and pilot the module activities. The evaluation activity will focus on the materials development aspect of the project. Data will be collected by the LessonSketch platform, which includes interviews with Fellows and their teams, perspectives of module writers, descriptive statistics of module use, and feedback from both teacher educator and preservice teacher end-users about the quality of their experiences. The first research activity of the project is design research on the kinds of technological infrastructure that are useful for practice-based teacher education. The PIs will identify tools that teacher educators need and want beyond the current capabilities for web-based support for use of rich media and will produce prototype tools inside the LessonSketch environment to meet these needs. The second research activity of the project will supplement the evaluation activity by examining the implementation of two of the modules in detail. This aspect of the research will examine the goals of the intended curriculum, the proposed modes of media use, the fidelity of the implemented curriculum, and learnings produced by preservice teachers. This research activity will help the field understand the degree to which practice-based teacher education that is mediated by an online access to rich media would be a kind of practice that could be easily incorporated into existing teacher education structures. The project will produce 6 to 8 LessonSketch modules for use in teacher education classes. Each module will be implemented in at least eight teacher education classes across the country, which means that between 720 and 960 preservice teacher candidates will study the materials. The project aims to shift the field toward practice-based teacher education by supporting university programs to implement classroom-driven activities that will produce mathematics teachers with strong capabilities to teach mathematics effectively and meaningfully.
