Content knowledge, strategic knowledge, and forms of knowledge organization used in phylogenetic tree construction are described to account for expert performance. A literature review is used to situate this research with respect to studies of: (a) the teaching of evolution, (b) problem-solving expertise, (c) physics and biology problem solving, and (d) the practice of phylogenetic systematics. Rationales are provided for the development of a computer-based problem-solving environment, model problems, and research problems and methodology.
Each problem consisted of a matrix of coded and polarized phylogenetic data organized by taxa and characters. Four series of research problems were constructed that varied …
