Measuring the Density of a Sugar Solution  Karen I. Peterson
This experiment addresses the concept of equipment calibration for reducing systematic error. Students prepare and measure the densities of sucrose solutions with simple glassware that has been calibrated using the density of water. By careful work, students can determine the density to within 0.5%. allowing accuracy to be a major component of the final grade.

Concept Learning versus Problem Solving: A Cognitive Difference  Mark S. Cracolice, John C. Deming, and Brian Ehlert
94 students in a first-term general chemistry course were tested with paired algorithmic¬Ěconceptual questions. Results showed that success on algorithmic questions was always higher than on conceptual questions and variation in scientific reasoning skills is one cause of the gap between algorithmic and conceptual problem-solving ability.

The authors sought to find those cases of partly soluble substances for which simple calculations such as Ksp=S2, and Ksp=4S3 can realistically be used for computing solubility from Ksp and the reverse calculation. Empirical solubility data are compared with solubilities calculated from reliable Ksp values that have been adjusted for activity coefficients. A table of 18 substances is suggested for textbook use.

There Seems To Be Uncertainty about the Use of Significant Figures in Reporting Uncertainties of Results  Julio F. Caballero and Delphia F. Harris

The package is a 3-disk set or a CD plus a record management disk. The program is divided into 24 chapters much like the topics of nearly all general chemistry textbooks. Each chapter is usually subdivided into four to six subsections. Each subsection contains instruction and a set of questions. Since the number of questions varies and the actual questions differ each time a student goes through the subunit, each student has a unique set of questions.
