I am really looking forward to my time in Indianapolis this week. I have made a page where people who come to my talks can obtain the powerpoints and handouts. Go to this link and that’s where all of the documents will be.
Last week I was being observed by a colleague and my class was doing an exercise in GeoGebra about circles, arcs and inscribed angles. I don’t think I can do the experience I had justice as I try to describe to you what happened in this class, but strangely, I just can’t believe that someone […]
Here are some links to documents that I will make public for my talks at the conference in Indianapolis this week: Powerpoint Presentation for Improving Classroom Discourse to Support Communication, Equity, and Students’ Agency Handout for Improving Classroom Discourse to Support Communication, Equity, and Students’ Agency Powerpoint Presentation for Problem-Based Learning (PBL): A Transformed Perspective […]
Whether it be a small arithmetic error, or correcting a student when they were actually doing something right, we always make mistakes in class. The other day, I wrote the parametrization of the unit circle as x=cos(t) and y=sin(t) and took the derivatives as dx/dt=sin(t) and dy/dt=cos(t). It wasn’t until a student humbly interrupted me […]
I received an email from a colleague a few weeks ago, that was amazingly touching. She had been meeting with an advisee and asked the thoughtful question, “Can you think of a course or a moment that changed your academic experience in a significant way.” One would think that most high school sophomores would either […]
The other day in my Algebraic Geometry class, we were doing this problem: An airplane is flying 36,000 feet directly above Lincoln, Nebraska. A little later a plane is flying at 28,000 feet directly above Des Moines, Iowa, which is 160 miles from Lincoln. Assuming a constant rate of descent, predict how far from Des […]
This fall I was asked to do a small workshop for my department about PBL since almost everyone will be teaching a course that has some component of problem-based learning involved in it. I think for some department members it was somewhat daunting, but I had so much respect for those who were trying something […]
The school year is upon us and it is with great excitement that I look toward this new school year. I just sent off the first draft of my dissertation proposal, we just got our edited version of geometry text back from the printers, and our newly edited trigonometry text is hot off the presses […]
I just returned from a wonderful conference at Ithaca College that was the First North American Conference on GeoGebra, a wonderful Open Source Dynamic Geometry Software package that you can find online at www.geogebra.org. It has been around for a while, but it is only just getting well-known because it is free! It is also […]
I spent a wonderful week on Long Beach Island with my family relaxing and enjoying the waves. It made me think deeply about the effects of the BP oil spill in the Gulf of Mexico and the news reports of the large balls of tar that were showing up on some beaches in Texas. So […]
