What happens in the classroom in the absence of the lab teacher?

Because Lab Classrooms

• Have well established rituals and routines
• Have well-defined roles and responsibilities
• Have students who are taught to work independently, in partners, or in groups
• Expect students to assume responsibility for accessing both materials and information
• Expect students to show respect and support for each other at all times

. . . students in Lab Classrooms are typically able to take responsibility for their learning with minimal help and guidance from a substitute teacher.
