Logic structures are flexible. They can be implemented from virtually anything that can be drawn as an hierarchical outline or a block diagram with connecting arrows. Flexible access controls allow a teacher to regulate who can see what and when. Users can jump between other computer applications, such as spreadsheets, word processors, and graphics software, without closing out and re- entering the conferencing system. Multiple windows are available.
Adequate technology is here.
The challenge is for teachers to develop pedagogical strategies and tactics that exploit this technology's potential for optimizing critical and creative thinking and active and collaborative learning.
