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. Bularzik, Joseph. J. Chem.

Improving Conceptions in Analytical Chemistry: c_{i} V_{i} = c_{f} V_{f} Margarita RodríguezLópez 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 massbased 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. RodríguezLópez, Margarita; Carrasquillo, Arnaldo, Jr. J. Chem.

CrossProportions: A Conceptual Method for Developing Quantitative ProblemSolving Skills Elzbieta Cook and Robert L. Cook This paper focuses attention on the crossproportion (CP) 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 lowerlevel chemistry courses. In recent years, the DA method has emerged as the only problem solving mechanism offered to highschool and general chemistry students in contemporary textbooks, replacing more conceptual methods, CP included.

Using a Graphing Calculator To Determine a FirstOrder Rate Constant: Author Reply José E. CortésFigueroa When technology is used to help with mathematical calculations, the emphasis must be on the concepts being learned rather than simply the procedures.

How Can an Instructor Best Introduce the Topic of Significant Figures to Students Unfamiliar with the Concept? Richard A. Pacer The focus of this paper is how best to introduce the concept of significant figures so that students find it meaningful before a stage is reached at which they become turned off. The approach described begins with measurements students are already familiar with from their life experiences and involves the students as active learners. Pacer, Richard A. J. Chem.

There Seems To Be Uncertainty about the Use of Significant Figures in Reporting Uncertainties of Results Julio F. Caballero and Delphia F. Harris A cursory review of two journals indicates that uncertainties in experimental results are not consistently reported in the literature with the correct number of significant figures. The problem seems more frequent in computer generated results in both chemical education and research articles. Examples of published values with uncertainty inappropriately reported are included along with the appropriate rounding. Caballero, Julio F.; Harris, Delphia F. J. Chem. Educ. 1998, 75, 996.

Precision and Accuracy in Measurements: A Tale of Four Graduated Cylinders Richard S. Treptow The concepts of precision and accuracy help students understand that uncertainty accompanies even our best scientific measurements. A model experiment can be used to distinguish the two terms. The experiment uses four graduated cylinders which give measurements of different accuracy and precision. Such terms as mean, range, standard deviation, error, and true value are defined through an illustration. Treptow, Richard S. J. Chem. Educ. 1998, 75, 992.

Solving equilibria problems with a graphing calculator: A robust method, free of algebra and calculus Ruch, David K.; Chasteen, T. G. The method of successive approximations is frequently introduced in freshman chemistry as a means for solving equilibrium equations.

An alternative method to solving such equations is to use graphic calculators to solve problems graphically. Ruch, David K.; Chasteen, T. G. J. Chem. Educ. 1993, 70, A184.
