Alison Wallum; Zetai Liu; Joy Lee; Subhojyoti Chatterjee; Lawrence Tauzin; Christopher D. Barr; Amberle Browne; Christy F. Landes; Amy L. Nicely; Martin Gruebele – Journal of Chemical Education, 2023
As data science and instrumentation become key practices in common careers ranging from medicine to agriscience, chemistry as a core introductory course must introduce such topics to students early and at an accessible level. Advanced data acquisition and data science generally require expensive precision instrumentation and massive computation,…

The Instrumental Model
Direct linkDirect link
Yeates, Devin Rodney – ProQuest LLC, 2011
The goal of this dissertation is to enable better predictive models by engaging raw experimental data through the Instrumental Model. The Instrumental Model captures the protocols and procedures of experimental data analysis. The approach is formalized by encoding the Instrumental Model in an XML record. Decoupling the raw experimental data from…

Sojka, Zbigniew; Che, Michel – Journal of Chemical Education, 2008
Laboratory and practical courses, where students become familiar with experimental techniques and learn to interpret data and relate them to appropriate theory, play a vital role in chemical education. In the large panoply of currently available techniques, it is difficult to find a rational and easy way to classify the techniques in relation to…
