It is widely accepted that including writing activities in the learning process positively impacts student achievement and leads to greater depth of student understanding. This writing is often missing in the math classroom though, when the focus is misplaced on rote procedures. In these classrooms students learn mathematical processes but have little depth of understanding into the mathematical foundations, nor have an ability to clearly express their mathematical reasoning. This article promotes the use of Internet-based chat, forums, and blogs as the environment in which necessary mathematical writing can occur. Zemelman, Daniels, and Hyde provide a best practice framework through which the benefits of chat, forum, and blog writing are obvious. Student engagement with material increases in a cooperative environment, where a real audience and purpose for writing is clear, and student ownership in personal learning grows. In addition, students mature in traditional reading and writing literacy and further develop critical thinking skills. (Contains 2 figures.)
