In Reif's method, students are asked to identify "significant times" in the problem. Any point that stands out as being when something changes or happens or otherwise looks important. Points such as the top of a ballistic arc or the beginning of a frictionless section of a surface being moved on. By finding these points, the student can assign subproblems that consider only the behavior either at a point or between points, rather than trying to solve the problem in one chunk. Early work with a mechanics lab last year suggested that student groups have trouble choosing these "Zones" of interest when not specifically guided through the process of identifying them. This raised the question of whether students were simply not thinking to look, or if they were looking and not finding. A series of multipart problems was designed and given to students with specific instructions on identifying the significant points and the Zones of interest. With the exception of some apparent misconceptions on the working of springs and the importance of collisions, students were able to break up the problems into manageable pieces when instructed to do so. This suggests that students can be successfully taught a method for identifying and solving subproblems, such as Reif's.
