In developing the framework and the tasks, the procedures for creating the problem solving
framework must be related to the cognitive model that one believes underlies the situation. The
researchers compared a factor-analytic approach with an information processing approach for identifying
the important dimensions to solve a probe of the students. The authors used both approaches to discover
appropriate dimensions for developing the model. The factor-analytic approach attempts to identify
distinct dimensions for creating the tasks but some dimensions are not necessarily required in sequential
order in the steps of problem solving. In contrast, an information processing approach identifies the
cognitive processes required in sequential steps in the problem-solving processes. The cognitive processes
may not be distinct in the different steps of the problem-solving process. In my view, these methods are
valuable for guiding assessment developers to generate the model form the theoretical framework
