Collaborative Research: Computer-Supported Math Discourse Among Teachers and Students

这个完整的研究和开发项目是设计，开发和测试一个尖端的学习环境，学生和教师解决数学问题，并通过虚拟环境与他人交流他们的思想。 本研究的主要目的是利用虚拟学习环境来提高数学教师和学生之间重要数学语篇的质量和数量。 研究人员将测试学习环境的可用性，以让学生参与高质量的话语。 研究人员还将研究虚拟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价来实现研究和开发目标。 本研究将采用混合的研究方法来考察虚拟学习环境对学生重要数学话语和数学成绩的影响，研究结果表明：（1）虚拟学习环境既是一种有效的数学教学工具，也是一种研究工具;（2）有助于我们理解网络数学话语的本质，以及如何在教师和学生中培养有意义的数学话语的质量和数量;以及（3）该项目可以为有效的在线课程交付提供见解。

This full research and development project is to design, develop, and test a cutting-edge learning environment where students and teachers solve mathematical problems and communicate their thinking with others through the virtual environment. The major focus is to increase the quality and quantity of significant math discourse among mathematics teachers and their students by using the virtual learning environment. The researchers will test the usability of the learning environment for engaging students in high quality discourse. The researchers will also examine the impact of the virtual learning environment on student significant mathematical discourse and achievement.The project uses a design research method as well as summative evaluations to achieve research and development goals. Mixed methods will be used to examine the impact of the virtual learning environment on student significant mathematical discourse and achievement.The findings of the project contribute to the field in three ways: (1) The virtual 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.
