If you are a lecturer, you probably monitor how well your students follow your lecture. You check from time to time by asking questions or you rely on the barometer of puzzled looks and distracted students to determine whether your teaching is cloudy or the fog of incomprehension has lifted. Questions are great. They interrupt your flow of words, giving time for people to think. And thinking is how one converts words into knowledge.
I recently started using iBooks Author, the free Apple software to create books or, in my case, multiple choice questions that I project from my iPad. Adding question slides that respond live to a click in a PowerPoint or Keynote presentation is near impossible. In ibook Author, it’s a cinch. You use questions as needed during the course (or at at the end of the course in a competition pitting one half of the class against the other to make things more fun). It takes time away from your teaching but giving that thinking time to the audience multiplies the productivity of your teaching, whether they answer correctly or not!
