Correspondents often ask whether there is research that establishes that my curricular materials are effective. The question is usually about the Lab Gear, but recently someone asked it about my pentomino materials.Unfortunately, I don't know the answer. If someone did this kind of research, they didn't tell me about it.What I do know is that… Continue reading Research

Actually, I get most of my ideas at conferences, in The Mathematics Teacher, and sometimes on the Web -- not so much from books any more. And of course, most importantly, I get ideas when trying to think differently about something I teach.Still,… Continue reading Book Recommendations
Web 2.0?
As I mentioned in a previous post, I am working on launching a math teachers' network, with the theme "Escape from the Textbook!". People have suggested these options for sharing files and ideas: edWeb, Google Docs, Google Groups, Google Wave, LinkedIn, Ning, ProjectSpace, WikiSpaces. My Web site is also available -- should that be helpful… Continue reading Web 2.0?
