On Wednesday, April 22nd the Junior High Mad Scientist option watched a live knee replacement surgery via videoconference. The surgery was performed at Mount Carmel Hospital in Columbus, Ohio, USA. Students prepared for this experience by performing a mock knee replacement surgery of their own online, as well practicing a variety of surgical procedures in the classroom. During the surgery, which was narrated in real time by a lead surgeon, students from across North America were able to ask the surgical team questions in the Operating Room. This shared learning experience was very rewarding for our students and we hope to be involved in more new and exciting videoconferences in the future!
