An analysis is presented of the experience and lessons learned of running a MOOC in introductory physical chemistry. The course was unique in allowing students to conduct experimental measurements using a virtual laboratory constructed using video and simulations. A breakdown of the student background and motivation for taking the course is presented, and the student feedback on the course is also provided. It is concluded that even practical based chemistry courses can be successfully delivered online and such courses have the potential to provide a valuable addition to campus based chemistry teaching at university level.
