Virtual Classroom with a Time Shift
نویسندگان
چکیده
In spring 2007, Prof. Sterling’s Introduction to High Performance Computing has been delivered in a virtual classroom consisting of 5 sites spanning Louisiana, Arkansas, and North Carolina in the USA and the Czech Republic in Europe. By utilizing a multi-point uncompressed audio and High Definition (HD) video capturing, transmission, and presentation system, a high fidelity collaborative environment was available to students, giving them access to the lecturer regardless of the place they attended the lecture. However, the semester start differs at individual participating educational institutions by several weeks and the institutions are also in different time zones. A store and replay technology was used in these cases, together with a larger number of lectures presented per week, to accommodate for this difference. The whole system worked well, the high quality of the HD video allowed students even in the most distant place to get a very good feeling of participating in a live lecture.
