新《课标》描述数学活动水平的过程性目标时,用了“体验”一词,即学生在实际生活情境中去感受和探索,从而发现和掌握数学知识,获得解决实际问题的方法策略。生活经验是引起学生情感体验的基础。在数学教学中,教师努力创设贴近生活的情境,促使学生在体验中寻找和解决问题。搜集数学信息,体验将实际问题转化为数学研究对象的演变过程数学来源于生活,并应用于生活。如果学生们能把实践问题变为数学研究对象,就会产生强烈的求知欲。以“小数的近似值”教学为例。笔者创设买水果的情境,并请同学计算钱数和开具发票。同学们展现
The new “curriculum” describes the procedural goals of the level of mathematics activities, the use of “experience”, that is, students in real life situations to feel and explore, in order to find and master mathematical knowledge, access to solve practical problems Strategy. Life experience is the basis of emotional experience of students. In mathematics teaching, teachers try hard to create situations that are close to life and encourage students to find and solve problems in their experiences. Collecting mathematical information and experiencing the evolution of the practical problem into the subject of mathematics. Mathematics derives from life and applies to life. If students can turn practical problems into mathematic subjects, they will have a strong thirst for knowledge. Take the “Approximation of Decimals” as an example. I create the situation to buy fruit, and ask students to calculate the amount of money and invoicing. Students show
