For dynamic situations, a system of dynamic decision-making is needed; a system which is being refreshed all the time by the decisions of its elements or members. We call it wise decision system or WDS. Our purpose for suggesting such a system is creating some criteria in order to consider whether the decisions made in the field of mathematics education and mathematics curriculum planning are wise or not. First, some specifications of this model have been introduced. Then an example from teacher training courses in district 1 of educational ministry in Tehran, Iran has been discussed. By the criteria which WDS suggests, decisions in the mentioned example have a room for improvement.

 

Key words: Mathematics education, wise decisions, situated decision, society, culture, self organization.
