As part of a larger investigation of preservice teachers' use of, and movement amongst, various modes of representing exponential relationships, this report focuses on one case study, that of Mike, whose facility in moving amongst representational registers was not matched by conceptual understanding of the underlying mathematical ideas as he attempted to solve algebraic problems involving exponential relationships. Mike's case casts doubt on the theoretical assumption that students who can move fluently amongst various inscriptions representing the same concept have of necessity attained conceptual knowledge of the relationships involved.
