the learner can set on the object is shown. In Figure 2(c), the learner chose friction as an
attribute to change. The learner is allowed to change the attribute value in the small window.
In this case, the value is zero in the original problem. By changing the new problem again,
the learner continuously carries out the problem-changing exercise.
