LEGO-Method--New Strategy for Chemistry Calculation
Molnar, Jozsef; Molnar-Hamvas, Livia
Online Submission, US-China Education Review B 7 p891-908 2011
The presented strategy of chemistry calculation is based on mole-concept, but it uses only one fundamental relationship of the amounts of substance as a basic panel. The name of LEGO-method comes from the famous toy of LEGO[R] because solving equations by grouping formulas is similar to that. The relations of mole and the molar amounts, as small perspicuous units (building blocks), are applied on the fundamental relationship (basic panel) and the problem can be solved as an algebraic operation. LEGO-method is much more simple than the other strategies (e.g., dimensional analysis, mole method or rule of three), because the students can understand and learn this procedure step by step at the very beginning of their science study. The measurements have demonstrated that those students, who learned the LEGO-method in the school, have used this strategy more frequently than other strategies for solving a stoichiometric problem. The success of these students indicates that the LEGO-method is a useful alternative strategy for teaching chemistry calculations and more complete understanding of problem-solving.
