Teaching Avogadro's Hypothesis and Helping Students to See the World Differently Brett Criswell
This article uses a model from educational psychologyChi's theory of ontological misclassificationto explain the source of students' difficulties in understanding Avogadro's hypothesis and provide a method to successfully teach this fundamental concept.
