Enhancing the Teacher-Curriculum Relationship in Problem-Based Mathematics Classrooms by Connecting Teacher and Student Digital Collaborative Environments

该项目将为中学数学教师创造一个促进协作的数字环境。教师的数字环境链接到学生协作环境，并包含相同的以问题为基础的课程材料。这种环境有助于教师之间的协作和相互学习。当教师计划、教授和反思学生的学习时，就会发生这种情况。这个在线的数字平台将帮助教师在可能位于不同学校的网络中更轻松地合作。在线资源将包括基于问题的课程材料、学生的课堂人工制品和教师创建的资源。该项目将学习教师如何使用资源，在数字环境中合作，以及通过网络相互支持。随着更多的课程资源被创建用于在线教学，该项目将有助于理解如何最好地支持数学教学和学习。基于设计的数学研究项目为教师研究数字协作环境，并将其与学生协作平台相结合，用于中学问题解决课程。我们的目标是设计和开发数字协作平台，以便教师网络可以创建、使用和共享教学资源，以规划、实施和反思学生的思维。该项目将包括中学教师参与设计过程。学生的环境使其他学生和老师都能看到学生的思考。这使得教师可以存档，然后检查学生的推理和思考。新的环境将允许与专业学习社区中的其他教师分享这项工作。研究问题是：网络教师如何根据需要访问、生成、使用和共享教学资源(包括课堂人工制品)，以支持数学教学(计划、实施和反思学生思维)？该项目将使用教师访谈和协作环境中的人工制品进行混合方法的数据收集和分析。教师反思资源将被用来了解他们如何看待学生的数学作业，以及他们如何使用平台资源。探索研究PRK-12计划(DRK-12)旨在通过研究和开发新的创新和方法，显著提高Pre-K-12学生和教师在科学、技术、工程和数学方面的学习和教学。DRK-12计划中的项目建立在STEM教育的基础研究以及为项目提供理论和经验证明的先前研究和开发工作的基础上。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。

The project will create a digital environment for middle school mathematics teachers to promote collaboration. The digital environment for the teachers links to a student collaborative environment and contains the same problem-based curriculum materials. The environment helps teachers to collaborate and learn from one another. This occurs when teachers plan, teach, and reflect on student learning. The online, digital platform will help teachers work together more easily in networks that might be at different schools. The resources online will include problem-based curriculum materials, classroom artifacts from students, and resources created by teachers. The project will learn about how teachers use resources, collaborate in the digital environment, and support each other through the network. With more curriculum resources being created for online teaching and learning, the project will help understand how mathematics teaching and learning can be best supported.The design-based research project in mathematics studies a digital, collaborative environment for teachers that is combined with a student collaborative platform for a middle school problem-solving curriculum. The goal is to design and develop the digital collaborative platform so networks of teachers can create, use, and share teaching resources for planning, enactment, and reflection on student thinking. The project will include middle school teachers in the design process. The environment for students enables student thinking to be visible to other students and the teacher. This allows the teacher to archive and then examine student reasoning and thinking. The new environment will allow that work to be shared with other teachers in a professional learning community. The research question is: how do teachers in networks access, generate, use, and share teaching resources (including classroom artifacts) as needed to support mathematics teaching (planning, enactment, and reflection of student thinking)? The project will use teacher interviews and artifacts from the collaborative environment for mixed methods data collection and analysis. Teacher reflection resources will be used to understand how they are thinking about students’ mathematical work and how they are using the platform resources. The Discovery Research preK-12 program (DRK-12) seeks to significantly enhance the learning and teaching of science, technology, engineering and mathematics by preK-12 students and teachers, through the research and development of new innovations and approaches. Projects in the DRK-12 program build on fundamental research in STEM education and prior research and development efforts that provide theoretical and empirical justification for the projects.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
