1. Learner-centered classrooms provide productive learning environments.

2. Comfortable and open exchange is promoted by treating all members of the class and their ideas with respect and thoughtful consideration. Ridicule, derision, and other non-respectful behavior inhibit learning and dialog.

3. Tasks and activities should be selected to support specific learning goals; it is not what you tell the students that determines what they learn, but what you ask them to do.

4. A good classroom environment promotes student curiosity, rewards creativity, encourages a spirit of healthy questioning, avoids dogmatism, and promotes meaningful understanding.

5. Wait-time is essential in prompting thoughtful responses and dialog.

6. A good science classroom welcomes all students and strives to enable all motivated students to be successful.
