直观能力是影响初中生数学学习的重要因素。学生空间想象力的培养需要大量的直观经验;需要通过大量的图形观察与分析逐步培养;需要生动多样的图形语言。初中数学教学中很多方面都体现着直观的作用,也都可以作为培养学生的几何直观能力的载体。
Intuitive ability is an important factor affecting junior high school students’ mathematics learning. The cultivation of students’ spatial imagination requires a lot of intuition; they need to be gradually cultivated through a large number of graphic observations and analysis; they need vivid and diverse graphic languages. Many aspects of junior middle school mathematics teaching embody the intuitive role, and can also be used as a vehicle for cultivating students’ geometrical intuitive ability.
