Question Starts: Pictures of Practice
What does the routine look like in action?

 

Using the routine to explore the topic of population density

At the beginning of a unit, Anne Clarke's high school biology class brainstormed ideas about their new topic: population density. What did they know about the topic? What kinds of questions did they have? What were they wondering about this new topic?

Post a list of the question stems in the classrooom to help students brainstorm interesting questions.

 

The opening conversation provided a perfect opportunity to use the Question Starts routine. Although they would be addressing the general issue of overpopulation in both humans and animals, Anne focused the discussion on Human Populations. Working individually and then in pairs, students used the questions stems from the routine to modify or transform existing questions from the brainstorm and generate and refine new questions. (See student list of questions below.) The lists of questions were shared with the whole group and served as a touch stone for investigation during the unit. Making the list available to students by posting it in the classroom allowed studnets to know when puzzles addresse or when knew infomation about a question was uncovered.
