Connecting Solubility, Equilibrium, and Periodicity in a Green, Inquiry Experiment for the General Chemistry Laboratory  Kristen L. Cacciatore, Jose Amado, Jason J. Evans, and Hannah Sevian
Presents a novel first-year chemistry experiment that asks students to replicate procedures described in sample lab reports that lack essential information. This structure is designed to promote students' experimental design and data analysis skills as well as their understanding of the importance and essential qualities of written and verbal communication between scientists.

Using the Relationship between Vehicle Fuel Consumption and CO2 Emissions To Illustrate Chemical Principles  Maria T. Oliver-Hoyo and Gabriel Pinto
This instructional resource utilizes consumer product information by which students compare theoretical stoichiometric calculations to CO2 car emissions and fuel consumption data. Representing graphically the emission of CO2 versus consumption of fuel provides a tangible way of connecting concepts studied in chemistry classes to everyday life.

Thermochemical Analysis of Neutralization Reactions: An Introductory Discovery Experiment  Kenneth V. Mills and Louise W. Guilmette
Describes a guided-inquiry laboratory pedagogy in which students discover chemical concepts in the lab and the instructor uses their pooled data to guide the lecture portion of the course. This method is illustrated by an experiment that reinforces students' understanding of stoichiometry and allows them to discover neutralization reactions and thermochemistry.

High School Chemistry Content Background of Introductory College Chemistry Students and Its Association with College Chemistry Grades  Robert H. Tai, R. Bruce Ward, and Philip M. Sadler
Do students who focus on some content areas in high school chemistry have an advantage over others in college chemistry? This manuscript seeks to answer this question through the use of a survey of 3521 introductory college chemistry students. The results indicate that studying stoichiometry in high school was most strongly predictive of college chemistry success.

Cross-Proportions: A Conceptual Method for Developing Quantitative Problem-Solving Skills  Elzbieta Cook and Robert L. Cook
This paper focuses attention on the cross-proportion (C-P) method of mathematical problem solving, which was once widely used in chemical calculations. We propose that this method regain currency as an alternative to the dimensional analysis (DA) method, particularly in lower-level chemistry courses. In recent years, the DA method has emerged as the only problem solving mechanism offered to high-school and general chemistry students in contemporary textbooks, replacing more conceptual methods, C-P included.

Evaluating Students' Conceptual Understanding of Balanced Equations and Stoichiometric Ratios Using a Particulate Drawing  Michael J. Sanger
A total of 156 students were asked to provide free-response balanced chemical equations for a classic multiple-choice particulate-drawing question first used by Nurrenbern and Pickering. The balanced equations and the number of students providing each equation are reported in this study. The most common student errors included a confusion between the concepts of subscripts and coefficients and including unreacted chemical species in the equation.

Using Knowledge Space Theory To Assess Student Understanding of Stoichiometry  Ramesh D. Arasasingham, Mare Taagepera, Frank Potter, and Stacy Lonjers
Using the concept of stoichiometry we examined the ability of beginning college chemistry students to make connections among the molecular, symbolic, and graphical representations of chemical phenomena, as well as to conceptualize, visualize, and solve numerical problems. Students took a test designed to follow conceptual development; we then analyzed student responses and the connectivities of their responses, or the cognitive organization of the material or thinking patterns, applying knowledge space theory (KST). The results reveal that the students' logical frameworks of conceptual understanding were very weak and lacked an integrated understanding of some of the fundamental aspects of chemical reactivity.

The Use of Extent of Reaction in Introductory Courses  Sebastian G. Canagaratna
This article discusses the use of the extent of reaction as an alternative to the traditional approach to stoichiometry in first-year chemistry. The method focuses attention on the reaction as a whole rather than on pairs of reagents as in the traditional approach. The balanced equation is used as the unit of change.
