时下,由素质教育和创新教育所带来的教学革命唤醒了沉闷的课堂,昔日冷冰冰的满堂灌、生硬的记忆教学已大为减少,许多数学教师已经成为课堂教学的改革者,各种教育技术和方法的运用,使得许多课堂教学已经如行云流水,教学氛围也已是教师声情并茂,学生兴趣盎然,教学效果也远非过去的可比,所有的这一切都在显示着教法的张力和潜力,教法已经为现代意义上的改革创造了可贵的经验,而且它还在进步与发展中.今天,我将自己平时的教学实践中的一点探索捧出来,旨在与广大同行们共同探讨为学而教的方法和技巧,此篇教学构思与设计源于我在2000年11月代表江苏省参加首届全国高中青年数学教师优秀课评比荣获一等奖的说课稿. 从可操作性的角度出发,我将《双曲线的几何性质》这一节的教学划分为三个阶段:
Nowadays, the teaching revolution brought about by quality education and innovative education has awakened the dreary classroom. In the old days, the cold and full-fledged intensive and memory teaching has been greatly reduced. Many mathematics teachers have become reformers in classroom teaching, and various educational technologies and The use of methods has led to many classroom teachings that are already running smoothly. The teaching atmosphere is also the teachers’ sensibilities. The students are full of interest and the teaching effects are far from comparable in the past. All of this shows the tension and potential of the teaching methods. The teaching method has already created valuable experience for reforms in the modern sense, and it is still progressing and developing. Today, I’ve brought up a little exploration in my usual teaching practice, aiming to explore together with my colleagues. Teaching methods and techniques, this teaching concept and design originated from the essay on behalf of Jiangsu Province in November 2000 to participate in the first national high school young mathematics teacher excellent class evaluation won the first prize. From the perspective of operability, I divided the teaching of the “Hyperbolic Geometry” section into three phases:
