Promoting Active Learning by Practicing the "Self-Assembly" of Model Analytical Instruments
Algar, W. Russ; Krull, Ulrich J.
Journal of Chemical Education, v87 n9 p942-944 Sep 2010
In our upper-year instrumental analytical chemistry course, we have developed "cut-and-paste" exercises where students "build" models of analytical instruments from individual schematic images of components. These exercises encourage active learning by students. Instead of trying to memorize diagrams, students are required to think deeply about the design and function of each of the components of the instruments they assemble, with particular emphasis on how different components interact. Students have found these exercises to be an engaging method that promotes improved understanding of instrument design. We provide a description and examples of these exercises, including a library of over 300 electronic images of components from which other instructors and their students can build a wide variety of instruments. In addition to student exercises, instructors can use these images to create custom diagrams for lectures or other course materials. (Contains 2 figures.)
