运用直观图形进行条件发散训练,就是根据应题确定的已知条体,在不改变确定条件实质意义的前提下,通过对直观图形的观察、分析、推理、挖掘应用题的隐含条件,从而掌握各条件之间的联系,条件与问题的“接触点”。这样有利于扩大学生的思维活动空间,提高学生分析应用题数量关系的能力。一、广泛发散已知条件广泛发散已知条件,就是根据应用题确定的条件,从学生的知识实际出发,通过直观图形,引导学生从纵横方面广泛发散,挖掘应用题的隐含条件。例如:某班有女学生32人,男生占全班人数的
The use of intuitive graphics for divergence training is based on the problem to determine the known article, without changing the substantive meaning of the conditions of the premise, through the visual graphics of the observation, analysis, reasoning, mining the implied conditions of the application so that Grasp the “contact points” between the conditions, the conditions and the problems. This will help expand students' space for thinking activities and improve their ability to analyze the quantitative relationship between applied questions. First, the widely divergent known conditions Widely divergent known conditions, that is, under the conditions determined by the application of questions, starting from the students' knowledge, through intuitive graphics to guide students to widely divergent aspect, mining the implied conditions of the application. For example: a class has 32 female students, boys accounted for the whole class
