Table 2: Samples of PSTs’ process description in Approach 2, Problem 1 For Approach 1, there was limited attention to Stuck in the PSTs’ descriptions of their process. For most of them, the focus was on the strategies they thought would work to resolve the problem. They recognized when something did not work or make sense or feel right, as in the case of PST 1 and PST2, when considered a major block to their progress, but these often were framed in a way that seemed to be less important to the process. The result was a process with the possibility of barriers to one’s strategy. The general orientation of their problem-solving model was to read problem, try a strategy, if does not work try something else, if out of ideas start over (re-read question) or quit.
