1. Secondary school students' difficulties with stoichiometry

Author

BouJaoude, Saouma and Barakat, Hala

Subjects
Chemistry, Physical and theoretical -- Study and teaching, High school students -- Education, Stoichiometry -- Study and teaching, Education, Science and technology
Abstract

Stoichiometry is a difficult subject to teach secondary school students but it is essential for understanding qualitative and quantitative chemical reactions. It is therefore essential that teachers design and use appropriate strategies to address these difficulties and to help students become conceptual problem solvers. A new study of students' problem solving strategies classifies them into three categories: correct, incorrect and incomplete strategies. Details of the study are further presented.

Abstract

A experiment designed to measure the stoichiometry of copper oxide is described. Specified quantities of copper oxide and charcoal are placed into a glass tube with an attached long narrow glass tube with a water band inserted. Water is added and then heated and the production of carbon dioxide raises the water band.
