In recent years, reflection-in-action hac; been a major concept for taking
account of the craft and practical aspects of teaching. Yet in the everyday
teaching praxis, reflection is largely absent. In this piper, we argue tha
t this absence is due to the fact that reflection requires objects of thoug
ht that have to be constructed. Both the construction and manipulation of t
hese objects requires "time out" from acting in real time. Taking time out
is frequently impossible in the praxis of teaching, unless we want to miss
the "teachable moments." We propose Spielraum, room to maneuver, as a conce
pt that describes the reality of teaching much better than reflection-in-ac
tion, especially when there is no time out for reflection. We use two exten
ded classroom episodes to exemplify situations that are better described by
the notion of Spielraum than by reflection-in-action.
