This video segment adapted from NOVA scienceNOW examines a developing theory that might explain a 250-million-year-old "murder mystery." While several possible causes have been considered for the mass extinction that occurred at the end of the Permian period, the scientists featured in the video thi
"Active learning" means getting involved, collaborating with others, and implementing concepts in the real world. It is intellectual hard work. But it allows you to remember the content better, understand it better and transfer it to other situations. Why does it work so well? We take a look at th
"Active learning" means you participate, collaborate with others, and apply concepts to the real world. It requires hard mental effort but leads to better retention and an understanding of the material that can be transferred to other situations. To explain how to apply Active Learning in classrooms
