教材是教师教学的重要资源,是教与学的重要依据。要创造性地使用教材,充分挖掘教材的教学功能,是我们教师都明白的一个道理,但又是我们教学中很容易忽视的问题。我们希望学生逐渐形成“用数学的眼光去观察周围的事物”能力,但有时或多或少地留下了一些遗憾。如果我们能够充分利用教材中有价值的问题线索,不断点燃学生求知的欲望,让学生感受到数学的有趣和价值,激发潜能,这正是我们数学教学追求的目标。现在我们再用“数学的眼光”重新 Teaching materials is an important resource for teaching, is an important basis for teaching and learning. To use the teaching materials creatively and to fully exploit the teaching functions of the teaching materials is a truth that all our teachers understand. However, it is a problem that can easily be overlooked in our teaching. We hope that students will gradually develop their ability to “see things in the world mathematically”, but they sometimes more or less leave some regrets. If we can make full use of the valuable clues in textbooks and ignite the desire of students for knowledge, let students feel the value and potential of mathematics, which is our goal of mathematics teaching. Now let’s re-use “math vision” again
