Instead, we ought to be using computers to do step three and using the students to spend much more effort on learning how to do steps one, two and four -- conceptualizing problems, applying them, getting the teacher to run them through how to do that.
换言之，我们本应该用计算机 去完成上述步骤三， 而让学生花更多的精力 去学好上述步骤一、二和四； 将问题概念化，并且运用它们， 让老师示范怎么去做。
