Sujak, Kamariah Binti; Daniel, Esther Gnanamalar Sarojini – Malaysian Online Journal of Educational Sciences, 2017
The purpose of this article is to determine the levels of understanding for solving Stoichiometry problems from the aspect of macroscopic, microscopic and symbolic representations of high, average and low achieving students after infusion of metacognitive skills. Nine form four students aged sixteen years old from a secondary school in Kuala…

Sattsangi, Prem D. – Journal of Chemical Education, 2014
A laboratory method for teaching inorganic qualitative analysis and chemical equations is described. The experiment has been designed to focus attention on cations and anions that react to form products. This leads to a logical approach to understand and write chemical equations. The procedure uses 3 mL plastic micropipettes to store and deliver…

Canac, Sophie; Kermen, Isabelle – Chemistry Education Research and Practice, 2016
Learning chemistry includes learning the language of chemistry (names, formulae, symbols, and chemical equations) which has to be done in connection with the other areas of chemical knowledge. In this study we investigate how French students understand and use names (of chemical species and common mixtures) and chemical formulae. We set a paper…

Lewis, Amy L. Micklos; Bodner, George M. – Chemistry Education Research and Practice, 2013
This study examined the understanding of chemical equations developed by three students with blindness who were enrolled in the same secondary-school chemistry class. The students were interviewed while interpreting and balancing chemical equations. During the course of these interviews, the students produced diagrams using Braille symbols that…

Davidowitz, Bette; Chittleborough, Gail; Murray, Eileen – Chemistry Education Research and Practice, 2010
This paper reports on a pedagogical approach to the teaching of chemical equations introduced to first year university students with little previous chemical knowledge. During the instruction period students had to interpret and construct diagrams of reactions at the submicro level, and relate them to chemical equations at the symbolic level with…

Page, Michael F. Z.; Escott, Patrick; Silva, Maritza; Barding, Gregory A., Jr. – Chemistry Education Research and Practice, 2018
This case study demonstrates the ability of high school chemistry students, with varying levels of math preparation, to experience learning-gains on state and district assessments as it relates to chemical reactions, thermodynamics, and kinetics. These advances were predicated on the use of a teaching style rooted in abstract reasoning. The…

Goodney, David E. – Journal of Chemical Education, 2006
Examples of acid-base reactions from Robert Boyle's "The Sceptical Chemist" are used to illustrate the rich information content of chemical equations. Boyle required lengthy passages of florid language to describe the same reaction that can be done quite simply with a chemical equation. Reading or hearing the words, however, enriches the student's…

Jurowski, Kamil; Krzeczkowska, Malgorzata Krystyna; Jurowska, Anna – Journal of Chemical Education, 2015
The concept of oxidation state (or oxidation number) and related issues have always been difficult for students. In addition, there are misunderstandings and obscurities, which can cause improper balancing of the chemical equations (mostly in organic reactions). In particular, these problems are related to determination of the oxidation state of…

Bong, Anita Yung Li; Lee, Tien Tien – Asia-Pacific Forum on Science Learning and Teaching, 2016
The purpose of this study is to identify the Form Four students' misconceptions in the electrolysis of molten compounds and aqueous solutions. The respondents were 60 Form Four students from two secondary schools in Sibu, Sarawak. The two instruments used in this study were an open-ended electrochemistry assessment and interview protocol. This…

Hanson, Ruby – Journal of Education and e-Learning Research, 2016
Chemical stoichiometry is a conceptual framework that encompasses other concepts such as the mole, writing of chemical equations in word and representative form, balancing of equations and the equilibrium concept. The underlying concepts enable students to understand relationships among entities of matter and required amounts for use when…

Chen, J.; Anderson, C. W. – Science Education International, 2015
Previous studies identified a learning progression on the concept of carbon cycling that was typically followed by American students when they progress from elementary to high school. This study examines the validity of this previously identified learning progression for a different group of learners--Chinese students. The results indicate that…

Shadreck, Mandina; Enunuwe, Ochonogor Chukunoye – Acta Didactica Napocensia, 2017
The study sought to find out difficulties encountered by high school chemistry students when solving stoichiometric problems and how these could be overcome by using a problem-solving approach. The study adopted a quasi-experimental design. 485 participants drawn from 8 highs schools in a local education district in Zimbabwe participated in the…

Irby, Stefan M.; Phu, Andy L.; Borda, Emily J.; Haskell, Todd R.; Steed, Nicole; Meyer, Zachary – Chemistry Education Research and Practice, 2016
There is much agreement among chemical education researchers that expertise in chemistry depends in part on the ability to coordinate understanding of phenomena on three levels: macroscopic (observable), sub-microscopic (atoms, molecules, and ions) and symbolic (chemical equations, graphs, etc.). We hypothesize this "level-coordination…

Cotes, Sandra; Cotuá, José – Journal of Chemical Education, 2014
This article describes a method of instruction using an active learning strategy for teaching stoichiometry through a process of gradual knowledge building. Students identify their misconceptions and progress through a sequence of questions based on the same chemical equation. An infrared device and software registered as the TurningPoint Audience…
