Cross-Proportions: A Conceptual Method for Developing Quantitative Problem-Solving Skills

Cook, Elzbieta; Cook, Stephen L.

Journal of Chemical Education, v82 n8 p1187 Aug 2005

The cross-proportion method allows both the instructor and the student to easily determine where an error is made during problem solving. The C-P method supports a strong cognitive foundation upon which students can develop other diagnostic methods as they advance in chemistry and scientific careers.
