Reasoning Strategies Used by Students to Solve Stoichiometry Problems and Its Relationship to Alternative Conceptions, Prior Knowledge, and Cognitive Variables.
Rohas de Astudillo, Luisa; Niaz, Mansoor
Journal of Science Education and Technology, v5 n2 p131-40 Jun 1996
Investigates reasoning strategies students use in solving stoichiometric problems and explores the relation between these strategies and alternative conceptions, prior knowledge, and cognitive variables. Results show how stoichiometric relations produce conflicting situations for students leading to conceptual misunderstanding of certain concepts. Concludes that student understanding improves if they conceptualize stoichiometric relations in terms of moles. Contains 50 references. (Author/JRH)
