Schnoebelen, Carly; Towns, Marcy H.; Chmielewski, Jean; Hrycyna, Christine A. – Journal of Chemical Education, 2018
The chemistry curriculum for undergraduate life science majors at Purdue University has been transformed to better meet the needs of this student population and prepare them for future success. The curriculum, called the 1-2-1 curriculum, includes four consecutive and integrated semesters of instruction in general chemistry, organic chemistry, and…

Halpern, Arthur M.; Frye, Stephen L.; Marzzacco, Charles J. – Journal of Chemical Education, 2018
Scientific Data Analysis Toolkit (SDAT) is a rigorous, versatile, and user-friendly data analysis add-in application for Microsoft Excel for Windows (PC). SDAT uses the familiar Excel environment to carry out most of the analytical tasks used in data analysis. It has been designed for student use in manipulating and analyzing data encountered in…

Thananatthanachon, Todsapon; Lecklider, Michelle R. – Journal of Chemical Education, 2017
In this experiment, students perform an air-free synthesis of three dichlorophosphinenickel(II) compounds, NiCl[subscript 2](PPh[subscript 3])[subscript 2], NiCl[subscript 2](PCy[subscript 3])[subscript 2], and NiCl[subscript 2](DPPE), using NiCl[subscript 2]·6H[subscript 2]O and the appropriate phosphine as the precursors. These colorful nickel…

Weiss, Charles J. – Journal of Chemical Education, 2017
The Scientific Computing for Chemists course taught at Wabash College teaches chemistry students to use the Python programming language, Jupyter notebooks, and a number of common Python scientific libraries to process, analyze, and visualize data. Assuming no prior programming experience, the course introduces students to basic programming and…

Gerczei, Timea – Journal of Chemical Education, 2017
A laboratory sequence is described that is suitable for upper-level biochemistry or molecular biology laboratories that combines project-based and traditional laboratory experiments. In the project-based sequence, the individual laboratory experiments are thematically linked and aim to show how a bacterial antibiotic sensing noncoding RNA (the…

Weiss, Charles J. – Journal of Chemical Education, 2017
An introduction to digital stochastic simulations for modeling a variety of physical and chemical processes is presented. Despite the importance of stochastic simulations in chemistry, the prevalence of turn-key software solutions can impose a layer of abstraction between the user and the underlying approach obscuring the methodology being…

Drury, Sara A. Mehltretter; Stucker, Kyle; Douglas, Anthony; Rush, Ryan A.; Novak, Walter R. P.; Wysocki, Laura M. – Journal of Chemical Education, 2016
A central goal of nonmajors chemistry courses is to instill within students the sense that chemistry does not occur in a vacuum but rather permeates everyday life. To encourage students to consider chemistry within the broader context of society and public policy, a week-long module in a survey course for nonmajors was designed to connect…

Pirinelli, Alyssa L.; Trinidad, Jonathan C.; Pohl, Nicola L. B. – Journal of Chemical Education, 2016
Polyacrylamide gel electrophoresis (PAGE) is commonly taught in undergraduate laboratory classes as a traditional method to analyze proteins. An experiment has been developed to teach these basic protein gel skills in the context of gluten protein isolation from various types of wheat flour. A further goal is to relate this technique to current…

Thananatthanachon, Todsapon – Journal of Chemical Education, 2016
In this experiment, the students explore the synthesis of a crystalline solid-state material, barium zirconate (BaZrO3) by two different synthetic methods: (a) the wet chemical method using BaCl[subscript 2]·2H[subscript 2]O and ZrOCl[subscript 2]·8H[subscript 2]O as the precursors, and (b) the solid-state reaction from BaCO[subscript 3] and…

DeKorver, Brittland K.; Towns, Marcy H. – Journal of Chemical Education, 2015
Little research exists on college students' learning goals in chemistry, let alone specifically pertaining to laboratory coursework. Because students' learning goals are linked to achievement and dependent on context, research on students' goals in the laboratory context may lead to better understanding about the efficacy of lab curricula. This…

Towns, Marcy; Harwood, Cynthia J.; Robertshaw, M. Brooke; Fish, Jason; O'Shea, Kevin – Journal of Chemical Education, 2015
An evidence centered design approach was used to develop, implement, and assess a novel and innovative digital pipetting badge using Purdue's Passport system. Each student in a large lecture course created a video demonstrating how to use a 10 mL pipet to dispense liquid. The video was uploaded into the Passport system, which allowed instructors…

Bain, Ryan M.; Pulliam, Christopher J.; Raab, Shannon A.; Cooks, R. Graham – Journal of Chemical Education, 2015
In this laboratory experiment, students learn how to use ESI to accelerate chemical synthesis and to couple it with on-line mass spectrometry for structural analysis. The Hantzsch synthesis of symmetric 1,4-dihydropyridines is a classic example of a one-pot reaction in which multiple intermediates can serve to indicate the progress of the reaction…

Weaver, Gabriela C.; SturtevantHannah G. – Journal of Chemical Education, 2015
Research has consistently shown that active problem-solving in a collaborative environment supports more effective learning than the traditional lecture approach. In this study, a flipped classroom format was implemented and evaluated in the chemistry majors' sequence at Purdue University over a period of three years. What was formerly lecture…

The Distributed Drug Discovery (D3) program trains students in three drug discovery disciplines (synthesis, computational analysis, and biological screening) while addressing the important challenge of discovering drug leads for neglected diseases. This article focuses on implementation of the synthesis component in the second-semester…

deSouza, Romualdo T.; Iyengar, Srinivasan S. – Journal of Chemical Education, 2013
A first-year undergraduate course that introduces students to chemistry through a conceptually detailed description of quantum mechanics is outlined. Quantization as arising from the confinement of a particle is presented and these ideas are used to introduce the reasons behind resonance, molecular orbital theory, degeneracy of electronic states,…
