Abstract

This article summarizes a paper by Yehudit J. Dori and Mira Hameiri, "Multidimensional Analysis System for Quantitative Chemistry Problems: Symbol, Macro, Micro, and Process Aspects" (J. Res. Sci. Teach. 2003, 40, 278-333), which describes the Multidimensional Analysis System (MAS), an approach to constructing, classifying, and analyzing introductory stoichiometry problems. In a comparison study the research population used the MAS problem solving approach for nine weeks on a particular topic; the control group studied the same topic for the same duration using a traditional instructional approach. Experimental group students scored significantly higher on an exit examination than their control group peers on the same examination. Students who had mathematics skills at the basic level benefited significantly more from MAS-based teaching than those whose mathematics level was more advanced.

  The effectiveness of problem solving as a learning tool is often diminished because students typically use only an algorithmic approach to get to the answer. We discuss a way of encouraging students to reflect on the solution to their problem by requiring ...

- Cross-Proportions: A Conceptual Method for Developing Quantitative Problem-Solving Skills
  Elzbieta Cook and Robert L. Cook
  Journal of Chemical Education2005 82 (8), 1187
  This paper focuses attention on the cross-proportion (C-P) method of mathematical problem solving, which was once widely used in chemical calculations. We propose that this method regain currency as an alternative to the dimensional analysis (DA) method, ...
