The Penny Experiment Revisited: An Illustration of Significant Figures, Accuracy, Precision, and Data Analysis  Joseph Bularzik
In this general chemistry laboratory the densities of pennies are measured by weighing them and using two different methods to measure their volumes. The average and standard deviation calculated for the resulting densities demonstrate that one measurement method is more accurate while the other is more precise.

Revisiting Molar Mass, Atomic Mass, and Mass Number: Organizing, Integrating, and Sequencing Fundamental Chemical Concepts  Stephen DeMeo
It is often confusing for introductory chemistry students to differentiate between molar mass, atomic mass, and mass number as well as to conceptually understand these ideas beyond a surface level. One way to improve understanding is to integrate the concepts, articulate their relationships, and present them in a meaningful sequence.

Improving Conceptions in Analytical Chemistry: ci Vi = cf Vf  Margarita Rodríguez-López and Arnaldo Carrasquillo Jr.
A common misconception related to analytical chemistry, which may be generalized as the failure to recognize and to account analytically for changes in substance density, is discussed. A cautionary example is made through the use of mass-based units of composition during volumetric dilution. The correct application of the volumetric dilution equation ci Vi = cf Vf is discussed. A quantitative description of the systematic error introduced by incorrect use of the volumetric dilution equation is also specified.

Are We Taking Symbolic Language for Granted?   Paul Marais and Faan Jordaan
This study formed part of a broader investigation into the role of language in teaching and learning chemical equilibrium. Students were tested for their understanding of 25 words and five symbols commonly used in connection with chemical equilibrium. This test showed that most of the students had an inadequate grasp of the meaning of all five symbols. It also showed that, on the average, their understanding of symbols was more problematic than their understanding of words.

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.
