Polls & questions during lecture

[balk]

Next Fall I will teach large section of calculus.

What would you recommend if I need the following two items?

1. I should be able to take polls in class.

Display on the board a Question with multiple choice answers.

Students choose one of possible answers using their cell phones.\\

Students should see the results of poll.

The results show how many students have chosen each possible answer. \\

I will explain those question that many students answered incorrect.

Credit to studentsfor participation in the poll.

2. Students should be able to ask Anonymous questions (by sending text from their phones).

The question is displayed on board.
