Why am I using LinkedIn anyway?

I don’t see what value, if any, my time spent managing my LinkedIn profile has given me. I have nearly 1000 connections on the site now, but I have only used it to contact people a few times, and people have only used it a few times to contact me. They could have contacted me […]

Questions to ask while problem solving

I’m working on a set of possible questions one can ask their students (and teach their students to ask themselves) while they are problem solving in math. Note that these questions are related to the work of George Pólya from his book How to Solve It. What would you add?   Questions to ask during […]

Pseudoteaching and the Edutainer

I recently came across Frank Noschese and John Burk‘s collection of posts on Pseudoteaching. In Frank and John’s words: What is pseudoteaching? This term was inspired by Dan Meyer’s pseudocontext, which sought to find examples of textbook problems that on the surface seemed to be about real world problems and situations, but actually were about […]

Mathematical mistakes

(Image base created by Curran Kelleher)   In the course I am taking online, How to Learn Mathematics, one of the assignments is to create a poster that highlights the importance of mistake making during the process of learning mathematics. What I believe is that mathematics is both in the external world (and hence discovered) […]

Math teachers are teachers of language

On Wednesday, the A2I team at New Visions participated in an excellent workshop from Harold Asturias on English language learners in a mathematics classroom. Harold made some points about the difficulties English language learners face in a mathematics class that really drove home this point to me; mathematics teachers are teachers of language too. To […]


Importance of questions Questions, both those asked by teachers and those asked by students, are an essential part of education. Questions can act as goals for learning, and motivate student curiousity about what they are learning. All teachers can attest to the fact that students who feel motivated to learn will learn much more effectively […]

Math Talk

At the SVMI institute, Sally Keyes led a workshop on the use of Math talks in the classroom. Some purposes of math talks are to present multiple ways of solving mathematical problems and to develop students’ ability to discuss mathematics. This helps students learn other strategies they can use, look for patterns between the different […]

Teach the controversy

(Image source: Wired Magazine)   If we teach as if everything we know is written in stone, our students will end up with the impression that knowledge is something static and unchanging, which is demonstrably false. A professor I had told me once, "Something is true when everyone stops complaining that it isn’t true." A […]

Jig-saw problem solving

Today in a workshop with Sally Keyes of the Silicon Valley Math Initiative, we started off the day with what I would call a jig-saw problem. Each of us was given a clue, and the instructions that for this activity we could not use pencil or paper, or share our clue card directly with our […]

Stop Googling everything

  It seems that a new habit has formed in our society, at least among people in our society who are net-savvy. Whenever anyone, anywhere, has a problem, the first way they almost always search for a solution is with an Internet search engine. Think of the implications. Instead of wondering how to solve something […]
