Agnello, Armelinda; Carre, Cyril; Billen, Roland; Leyh, Bernard; De Pauw, Edwin; Damblon, Christian – Journal of Chemical Education, 2018
The analysis of spectroscopic data to solve chemical structures requires practical skills and drills. In this context, we have developed ULg Spectra, a computer-based tool designed to improve the ability of learners to perform complex reasoning. The identification of organic chemical compounds involves gathering and interpreting complementary…

Schlotter, Nicholas E. – Journal of Chemical Education, 2013
Our ability to statistically analyze data has grown significantly with the maturing of computer hardware and software. However, the evolution of our statistics capabilities has taken place without a corresponding evolution in the curriculum for the undergraduate chemistry major. Most faculty understands the need for a statistical educational…

Santos-Delgado, M. J.; Larrea-Tarruella, L. – Journal of Chemical Education, 2004
The back-titration methods are compared statistically to establish glycine in a nonaqueous medium of acetic acid. Important variations in the mean values of glycine are observed due to the interaction effects between the analysis of variance (ANOVA) technique and a statistical study through a computer software.

Chambers, Kent A.; Blake, Bob. – Journal of Chemical Education, 2008
This study focuses on the effect of using a computer-based competitive learning system called LearnStar, as supplementary instruction in introductory chemistry courses. The outcomes evaluated were of student performance on classroom exams, the cumulative final, overall course grade, overall DFW rate (the percentage of student receiving a D, F, or…

Copeland, Thomas G. – Journal of Chemical Education, 1984
Nonlinear least squares computer programs are extremely valuable in fitting complicated equations to experimental data. They are easy to use and free students and teachers from the tedium of trying to derive linearized forms to complicated equations. The use of these programs (available for most medium/large scale computers) is discussed. (JN)

Lotz, A. – Journal of Chemical Education, 1995
Describes an experiment from a physical chemistry course that consists of a computer simulation of throwing dice and the statistics involved. The experiment is designed to improve students' understanding of statistical evaluation of experimental data and to introduce programming techniques. (DDR)
