“解决问题”教学的着眼点是什么?教“类型”?教“解法”?还是教“策略指导”?“解决问题”的学习价值又是什么?仅仅是为了获得问题的结论或答案吗?我认为,如果学生解答了很多题,但没有形成解决问题的基本策略,就大大降低了解决问题的教学价值。一、注重数量关系分析的指导在解决问题时,分析数量关系是从“数学问题”到“用数学方法解决”的“桥梁”。在学生用一定的方式表述问题后,要进一步引导学生分析有关信息,分析已知数量之间、已知数量与未知数量之间
“Problem solving ” teaching what is the focus? Teach “type ”? Teach “solution ” or teach “strategy guide ”? “Problem solving Is it to get a conclusion or answer to the question? I think if students answer many questions but do not form the basic strategy to solve the problem, they will greatly reduce the teaching value of solving the problem. First, focus on the guidance of quantitative relationship analysis In the solution to the problem, the analysis of the quantitative relationship is ”bridge “ from ”mathematical problems “ to ”mathematically method to solve ". Students in a certain way after the expression of the problem, we must further guide students to analyze the relevant information, analysis of the known quantity, between the known quantity and the unknown quantity
