Multidimensional: Different roles as a teacher (student,friend,coworker,colleague,parent)
Simultaneous: Classroom events that occur.(students needing help, bathroom pass, homework collection)
Immediate: The amount of decisions you must make as a teacher.
Public: You are in a fishbowl as a teacher!
Unpredictable: Your students will not always respond the way you may have planned, and things may not go as you think.
