Large urban schools have to cope with a "super-diverse" population with a multireligious background in their classrooms. The job of the science teacher within this environment requires an ultra-sensitive pedagogical approach, and a deeper understanding of students' backgrounds and of scientific epistemology. Teachers must create a safe learning atmosphere where students will be allowed to express their views about religion and science, especially when studying topics such as evolution and the Big Bang Theory. This article describes a different approach to teaching the Big Bang Theory developed in order to break down barriers that may exist between religious beliefs and scientific understanding.
