解应用题是小学数学内容的重点,也是难点。为降低学生学习的难度,九年义务教育全日制小学《数学教学大纲》(试用)增加了ax±bx=c这一类型方程的解法,从而扩大了用方程解应用题的范围,强化了方程的应用。但学生当前学习的现实情况是:明明用方程解起来简便的应用题,仍多用算术方法去解,这不仅增加解题难度,还导致错误增多,其原因在于学生还未形成用方程解应用题的意识。为
Solving the problem is the primary school mathematics content is also difficult. In order to reduce the difficulty of learning, the solution of ax ± bx = c is added to the mathematics syllabus of nine-year compulsory education full-time elementary school, which expands the scope of the problem solving equation, Applications. However, the reality of students' current learning is that the solution to the problem is to use the arithmetic solution to solve the problem, which not only increases the difficulty of solving the problem but also increases the error. The reason is that the students have not yet formed the problem solving equation Consciousness. for
