Problem Solu+on
Lectures take too long to prepare and are too 1ring to give
Let the students explain things to each other
Explaining how molecules behave is too hard
Let simula1ons do the work (show, don’t tell)
I explain the same thing over and over again
Record it once
My students think “algebra” is a some sort of underwear made of seaweed
Let soEware do the tedious work
Wri1ng and grading homework takes too much 1me
Put it on the web
Tools for the lazy teacher
or How to use sarcasm to convince teachers to use new tools

What? Why?
Simula1on tools Makes chemistry less abstract A simula1on is worth 10,000 words
Polling tools Immediate feedback/ ac1ve learning
Pen-‐ and screencast “Lecture” on demand/repeat/skip Example problems
Wolfram Alpha (Maple/Mathema1ca) Focus on the science, not the math
PeerWise Immediate feedback/guided learning
