Abstract: The five representation hierarchies and four kinds of strategy are presented for stoichiometric chemical problem solving on the basis of other's relative researches on this domain in several decades,and at the same time 15 typical students are studied as cases in detail with Think-Aloud method.The results suggest that the strat egy chosen depends on the degree of representation(including representation time and accurate representat ion rate) and students with deep representation are inclined to choose superi or strategies when students are solving stoichiometric chemical problems.

Key words: stoichiometric chemical problem, representation, strategy
