Accommodation: Accommodation can be viewed as a competition between conceptions. Once students are aware of an understandable and initially plausible alter- native to an existing conception, the relative status of these conceptions is the issue. Dissatisfaction with the existing conception decreases its status, while exploring the fruitfulness of an alternative conception increases the alternative's status (Hewson, 1983). As long as the existing conception's status is greater than the alternative's (for whatever reason), accommodation will not proceed. Whenever the alternative's status exceeds the existing conception's status, accommodation, for the time being, will move forward. But, as we have discussed, many factors affect status. Therefore, competition between conceptions results in a process ofaccommodation characterized by temporary advances, frequent retreats, and periods of indecision. ... It rarely seems characterized by either a flash of insight, in which old ideas fall away to be replaced by new visions, or as a steady logical progression from one commitment to another. Rather, it involves much fumbling about and many false starts and mistakes.
