摘要
决策是决策者对未来实践活动的目标、方针、原则和方案所作的策略抉择，决策能力是一个人综合素质的具体体现，发展学生解决问题的决策能力是数学教学的重要目标之一．决策具有整体性、转换性、自我调节性等特征．根据数学问题的类型及解决问题时的决策特点9可将数学决策分为3种类型：确定性决策、不确定性决策和尝试性决策．当下的数学决策教学存在着“确定性决策机械化”与“不确定性决策确定化”现象．数学决策教学应立足于“问题引导，过程决策”模式，同时抓好几个关键点：（1）即时培养学生的决策意识；（2）理性对待决策活动中的“非标准思路”；（3）尊重决策活动的“自组织性”．
A piece of decision-making was to choose the strategy of future pratice on aim, policy, principle and project. It was an important goal of mathematics teaching to develop a students＇ decision-making capability as an embodiment of his all-around development. A piece of decision-making was whole, variable, self-adjustable. As the variety of mathematical problems and the characteristic of problem-solving, decision-making was divided into three categories which comprise determinate decision-making, undaterminate decision-making and attemptable decision-making. At precent, the phenomena which were ＂determinate decision-making inclining mechanization＂ and ＂undeterminate decision-making inclining determination＂ were accompanying by the mathematical teaching. The mathematical teaching with decision-making should obey the pattern problems leading and process decision-making.
