思维是人类认识活动的重心,认识能力的发展主要取决于思维的发展.数学教育的学科特点恰好在于它能有效地促进思维发展,因此利用数学课堂教学对培养学生的思维能力十分重要.下面以《直线与平面平行的判定与性质》一节课为例来具体论述,该课获1999年东北地区中学数学优秀课一等奖、“十佳课”.1 引导观察,培养数学思维的目的性 请学生观察实例“门的开与关”,目的是引导研究问题的方向,打开数学思维之门.
Thinking is the focus of human cognition. The development of cognition depends on the development of thinking. The disciplinary characteristics of mathematics education is precisely because it can effectively promote the development of thinking. Therefore, the use of mathematics classroom teaching is very important for cultivating students’ thinking ability. The first chapter of the “Judgement and Character of Parallelism between the Straight Line and the Plane” is used as an example to explain the lesson. This class won the first prize in the 1999 Middle School Mathematics Excellent Course and the “Top Ten Lessons”.1 Guided observation to cultivate the purpose of mathematical thinking. Ask the students to observe the example of “opening and closing of the door” in order to guide the direction of the study and open the door to mathematical thinking.
