Using Powerpoint Presentations In Classrooms

My wife teaches university students and she really enjoys using Powerpoint presentations in class³. Most lectures by visiting scholars, as well as research, is usually presented with some kind of presentation. In the math world, it’s usually some Linux-based derivative.

I’ve been going to a class where the professor solely relies on using Powerpoint presentations. I have come to hate them. The reason is that the professor doesn’t understand how much time it takes for students to note down what they see on the slides. Sure, the presentation is made available later on the web, but I like taking notes. That’s how my learning process works. I know that most students work in similar fashion.

The professor shows a theorem, barely explaining it and the rushes through a demonstration. I haven’t even finished noting down the theorem when he’s already midway through the demo. It’s very annoying. The other extremely annoying fact is that the demos, or parts of them, vanish because animation is used in the Powerpoint. Extremely frustrating⁵.

More Cheap Graduate Texts

Principles of Real Analysis by Aliprantis
Principles of Real Analysis by Aliprantis

So I went back to the book store³ and went through all of their books⁴. I couldn’t order Measure and Integral by Wheeden because it was just too expensive for my taste. Instead, I bought Principles of Real Analysis by Charalambos Aliprantis. I paid $30 for the hardcover 3rd edition, which is out of print because it’s listed on Amazon for $140. I wouldn’t mind getting the companion problem book as well. The Principles book was a third of the price of Measure. I’ve decided to get a photocopied version of that book. Since I was there, I ordered Real and Complex Analysis by Walter Rudin, a steal at only $15.

While browsing through the aisles, I saw Probability Theory I and II by M. Loève. Both were original hardcover editions that cost me $6.18 each. In the US, you’d bay between $70-90 for each volume. They are vol 45 and 46 in Springer-Verlag’s Graduate Texts in Mathematics. I found a few cheap undergraduate texts as well. Serge Lang’s Calculus of Several Variables, hardcover 3rd edition, David Bressoud’s Second Year Calculus, and Murray Protter’s Basic Elements of Real Analysis. They cost me respectively $9, $6.18, and $6.18.
