“问题引导式”在基准位移误差教学中的尝试

Attempt with Problem-Inducing Mode in Teaching of Benchmark Displacement Error

针对教材中定位销与圆柱孔固定边接触时基准位移误差的计算方法的不足,采用"问题引导式"的教学方法,引导学生理解孔销间隙配合时基准位移误差计算的适用条件,从而取得了较好的教学效果。

According to the shortage of calculation method for datum displacement error with the positioning pin and cylinder hole contacting at a fixed edge, the problem-inducing teaching method is used to induce students to understand the applicable condition for calculating datum displacement error of clearance fit between positioning pin and cylinder hole, leading a better teaching effect.
