• Resumen

  • A tactile problem-solving strategy is described that helped students analyze spectral data, primarily from 1H NMR spectra, to determine the structures of unknown compounds. Two important elements in that process were (i) students organized their analysis in a table and (ii) they drew each molecular fragment, deduced from their analysis, on a separate sticky note. Possible combinations of the fragments were analyzed by arranging the sticky notes in different ways, comparing back to the given data to determine the most plausible structure of the unknown compound. As part of the structure determination lesson in a large class, a document camera served to project the sticky notes to the screen and student involvement was encouraged.
