She first introduces two teachers, comparing their different styles of teaching. Hendry practices a constructionist approach, and has her students learn about measurement by figuring out how big the outline of a ship drawn on the floor is. Through her questioning, the children generate their own ideas about the rules of measurement and the need for a standard measuring device. Schweitzer, on the other hand, taught her students about measuring through a lecture approach, in which she gave them the information she felt necessary. Believing that students would gain more from a constructivist approach, however, she decided to change her style of teaching.
As Schweitzer quickly learned, there is no single way to teach a constructivist classroom. The most important idea is to be open to the students' suggestions, and question how they reached their conclusions. Letting them think problems through for themselves, and bouncing ideas off of each other is an important part of the learning process, and helps them to better understand and retain concepts. Constructivist teaching could be frustrating and is a continual learning experience for the teacher, but the emphasis should be on the teacher's awareness of the students' thoughts, rather than on the final outcome.
There were a few questions raised by this approach:
There are certain concepts a child must grasp by the end of certain grades; how can you ensure that they get through that material? How much structure should you provide?
