“水平运动物体的地转偏向”是地球自转的地理意义之一，成因不作教学要求，但其偏转规律却是教学的重点和难点。每当学到该内容，总有一部分学生始终无法运用地转偏向力的规律去解决实际问题，特别是对水平运动物体偏转方向的判断存在很大疑问。为突破这一难点，我发动学生到实际生活中“寻找”地转偏向力，在“寻找”的过程中感悟、领会地转偏向的规律。

"Horizontal motion object Coriolis" earth rotation is one of geographical significance, causes no teaching requirements, but its deflection regularity is the focus and difficulty of teaching. I learned the content, there is always a part of the students has been unable to use the Coriolis force laws to solve practical problems, especially on the level movement object deflecting direction judgments in the presence of considerable doubt. To break through this difficulty, I led students to real life " for " the deflection force of earth rotation, in the " search " in the process of understanding, comprehend the Coriolis law.
