This full research and development project is to design, develop, and test a cutting-edge online collaborative learning environment where students and teachers solve mathematical problems and communicate their thinking with others. The major focus is to increase the quality and quantity of significant math discourse among mathematics teachers and their students by using this online collaborative learning environment. This online collaborative learning environment is based on PIs' prior work called Virtual Math Teams that integrates synchronous and asynchronous media with the first multi-user dynamic-math-visualization application. The researchers will test the usability of the online ollaborative learning environment for engaging students in high quality discourse. The researchers will also examine the impact of the online ollaborative learning environment on students' significant mathematical discourse and achievement.The project uses a design research method as well as summative evaluations to achieve research and development goals. Discourse analysis and regression models will be used to examine the impact of the online collaborative learning environment on student significant mathematical discourse and achievement.The findings of the project contribute to the field in three ways: (1) The online collanorative learning environment can be both an effective pedagogical tool and a research tool in mathematics education; (2) It will contribute to our understanding about the nature of mathematical discourse online as well as about ways to foster the quality and quantity of significant math discourse among teachers and their students; and (3) This project can provide insights into effective online deliveries of courses.

这个完整的研发项目旨在设计、开发和测试尖端的在线协作学习环境，学生和教师可以在其中解决数学问题并与他人交流想法。 主要重点是通过使用这种在线协作学习环境来提高数学教师及其学生之间重要数学讨论的质量和数量。 该在线协作学习环境基于 PI 之前称为 Virtual Math Teams 的工作，该工作将同步和异步媒体与第一个多用户动态数学可视化应用程序集成在一起。 研究人员将测试在线协作学习环境让学生参与高质量讨论的可用性。 研究人员还将研究在线协作学习环境对学生重要数学话语和成就的影响。该项目采用设计研究方法以及总结性评估来实现研究和开发目标。 话语分析和回归模型将用于检验在线协作学习环境对学生重要数学话语和成就的影响。该项目的研究结果在三个方面对该领域做出了贡献：（1）在线协作学习环境既可以成为数学教育中的有效教学工具，也可以成为研究工具； (2) 它将有助于我们理解在线数学讨论的本质，以及如何提高教师和学生之间重要数学讨论的质量和数量； (3) 该项目可以提供有效在线课程交付的见解。
