High school biology teacher Dave Steinbacher has to deal with students who simply are not interested in biology and do not find it relevant in their lives. See how Steinbacher makes his class relevant by connecting his area of study with things that might interest students, like mysteries in history and space junk in Africa. Educational psychology shows that the most natural and easiest way to learn is when we have a need to learn the material. Creating an environment that fosters that desire to learn will increase student learning in any subject.
