Coldeway’s Quadrants

The concept of the quadrants in education was defined by Dan Coldeway, Dakota State University, in 1990s. The fictionalized version of creation of the quadrants is described in The Quarterly Review of Distance Education, Volume 4(2), 2003 (Dan Coldeway is passed away in 2003): "During the discussion, he pulled out a cocktail napkin and began to write. First he drew an x-y axis, and then he labeled each quadrant. In the upper left he wrote ST-SP, in the upper right he wrote ST-DP, in the lower left he wrote DT-SP, and in the lower right corner he put the letters DT-DP." Now they are referred as Coldeway’s Quadrants.

Dan Coldeway defines four ways in which education can be practiced:
1. Same-time and same-place (ST-SP) education is traditional classroom education.
2. Different-time and same-place (DT-SP) means that education occurs in a learning center; or students can attend classes at the same place, but at a time students choose.
3. Same-time and different-place (ST-DP) means that telecommunication systems are used. Teleconferencing or chat rooms are used to connect the students in different places at the same time. This type of education is called synchronous distance education which allows students to communicate in real time.
4. Different-time and different-place (DT-DP) is the purest form of distance education. Teachers and students may communicate asynchronously--at different times.
