In an excellent post awhile back, Larry Cuban summarized research related to how many decisions a teacher has to make each day:

*Researchers Hilda Borko and Richard Shavelson summarized studies that reported .7 decisions per minute during interactive teaching.

*Researcher Philip Jackson (p. 149) said that elementary teachers have 200 to 300 exchanges with students every hour (between 1200-1500 a day), most of which are unplanned and unpredictable calling for teacher decisions, if not judgments.

Now, a new study (thanks to Dan Willingham for the tip) has identified the number of research-based options we have to choose from when we make these decisions:


There’s certainly no reason why someone with just a few weeks training shouldn’t be able to handle teaching a class, wouldn’t you say?
