Joe Ruhl, an inspiring teacher, talks about the four Cs of teaching and learning - collaboration, communication, critical thinking and creativity - and includes two more - choice and caring. He shows us how he implemented these ideas into his high school biology classes and tells us what students will remember the most, years later.

Joe Ruhl has been sharing the joys of biology with kids for 37 years. He presently teaches biology, genetics, and science research courses at Jefferson High School in Lafayette, Indiana.

This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at http://ted.com/tedx
