"While non-mathematical technologies and tools (e.g., word processing, presentation, and communications software) have a role in the mathematics classroom (Cohen & Hollebrands, 2011), they provide a more supportive role andIn the final version (now available from NCTM in book & eBook form) which I highly recommend purchasing*, the paragraph above was replaced with the following on page 79-80:do not have the direct potentialto promote student reasoning, sense making, and mathematical thinking found in mathematical action technologies."

"Non-mathematical technologies and tools (e.g., word processing, presentation software, and communications applications) can also support interactions in the mathematics classroom (Cohen & Hollebrands, 2011). For example, student responses to an interactive poll can be quickly gathered through the use of either a dedicated clicker system or applications on a range of mobile device platforms, to provide teachers with informative information that may help guide instruction. Interactive whiteboards, document cameras, and web-based presentation applications can help students communicate their thinking to classmates and receive constructive feedback. Students sharing of work can occur beyond the boundaries of the face-to-face classroom through the use of secure Web-based platforms to post and comment on student-made podcasts, digital images of student work, and student presentation files. Students might use text messaging, cloud-based shared documents, virtual whiteboards, blogs, or wikis to collaborate on mathematical problems within the school or with students in other states or provinces or even countries (Rochelle et al. 2010). By making use of these electronic tools, students have a greater sense of ownership of the mathematics their learning, since the applications promote a sense of shared enterprise in the learning of mathematics.

Finally, a wide variety of web-based resources support the teaching and learning of mathematics. Teachers are increasingly using personal and shared pages to organize and categorize the resources they find most useful. These lists allow them to quickly locate resources that they have found useful in the past and share these with others through social media. Their capacity to do this represents, in a sense the virtual opening of the classroom door to allow for collaboration among classrooms and teachers. Furthermore teachers can organize shared pages to enhance communication with their students and their students’ parents or caregivers."
