This symposium in honor of the contributions of David Treagust to research on the teaching and learning of chemistry contained papers on student understanding of the macroscopic-particulate connection by M. H. Towns; David Treagust's influence on the design of instruction and assessment to address student difficulties with understanding electrochemical cells by T. J. Greenbowe; diagnostic assessment for curricular change by J. E. Lewis, J. A. Arjoon, K. Heredia, U. Kulatunga, S. M. VillafaƱe, and X. Xu; measuring what students know about chemistry by S. Bretz; vsualizing atomic and molecular behavior. By M. R. Abraham and J. I. Gelder; visualizing chemical concepts through stop-motion animations by W. K. Graeber; just because you've always done it that way doesn't mean it's not incredibly stupid by M. M. Cooper; and the role of multiple representations and diagnostic assessment to enhance the teaching and learning of chemistry concepts by D. F. Treagust.
