Understanding powers–individual concepts and common misconceptions

Résumé

The topic of powers and exponents is generally considered one major obstacle for learners in schools and universities. Our main goal is to answer the question: How can we bridge the gap between individual conceptions in students` minds and the relevant mental models (Grundvorstellungen) to conceptualize powers? With reference to this learning object, two tasks from our test instrument and initial results are presented, which are part of our diagnostic tool to enable the uncovering of students´ individual images and misconceptions in the area of powers, by means of comparing the prescriptive with the descriptive level of relevant mental models.
