Multicultural Dimension: 

*The program is designed to engage the learning styles of all participants and address the needs of students of diverse cultural backgrounds.
*Inquiry, although not identical in style from culture to culture, is an important part of how all cultures extend knowledge.
*The informality of the lab allows a teacher to work with an individual or a pair of students who might be struggling with a given skill or concept.
*Students work with other students whose cultural background may be quite different from their own during the term. As they work together to solve a problem, they must talk, plan, and work out a plan for successful completion of the task at hand. This model for open inquiry enables students to share their learning with fellow students.
