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.
