The Northeast Parallel Architectures Center at Syracuse University and the Computer Science Department at Jackson State University are now in their fourth semester of teaching computational science courses using the TANGO Interactive collaboratory system. All the course materials are on-line, and lectures are given twice a week in real time over the Internet. After the successful experience teaching undergraduates at JSU by faculty at SU in the first year, this report covers additional aspects of the teaching experience for graduate classes in the second year, additional improvements of technology for dealing with network bandwidth issues and teaching support, and the start of JSU faculty teaching a distance course at a third university.
