William J. Howitz; Taylor Frey; Shannon J. Saluga; Melanie Nguyen; Kameryn Denaro; Kimberly D. Edwards – Journal of Chemical Education, 2023
This paper describes the creation of a theme-based first quarter, of a two quarter sequence, general chemistry laboratory course following an argument driven inquiry format and employing specifications grading. The course contains four, two-week projects investigating the chemistry of a popular sports drink. The sugar content, dye concentration,…

Kovacevic, Tanja; Skinner, Austin; Fisk, John D.; Fishback, Vanessa; Reed, Scott M. – Journal of Chemical Education, 2020
The complete structural analysis and resynthesis of an unknown compound, selected from a library of dipeptides, provided a framework for a course that built from expository experiments toward a guided-inquiry approach. We used this semester-long lab as a replacement for conventional second semester organic chemistry laboratory and successfully…

Bopegedera, A. M. R. P.; Coughenour, Christopher L. – Journal of Chemical Education, 2021
A new project-based laboratory (PJBL) was developed for general chemistry students to tackle the steps involved in chemical water quality analysis using an accessible, real-world hydrologic system (the lakes of the Lower Grand Coulee, Washington). This PJBL was developed in a joint general chemistry and environmental geology course by a…

Hammerstad, Marta; Røhr, Åsmund K.; Hersleth, Hans-Petter – Biochemistry and Molecular Biology Education, 2019
Many laboratory courses consist of short and seemingly unconnected individual laboratory exercises. To increase the course consistency, relevance, and student engagement, we have developed a research-inspired and project-based module, "From Gene to Structure and Function". This 2.5-week full-day biochemistry and structural biology module…

Kylie L. Luska – Journal of Chemical Education, 2022
A multioutcome, guided inquiry-based liquid--liquid extraction (LLE) experiment has been designed for introductory organic chemistry. Multiple outcomes were established by identifying a series of red and blue dyes that are (1) soluble in organic solvent, (2) soluble in aqueous solution, or (3) soluble in either the organic or aqueous layers by…

Kocemba-Pilarczyk, Kinga A.; Ostrowska, Barbara; Dudzik, Paulina; Markiewicz, Michal J.; Sotirios Souza Pegos, Débora; Lim, Chaewon – Biochemistry and Molecular Biology Education, 2019
Diagnostic molecular biology is a fast developing discipline of laboratory medicine widely used in numerous medical branches such as oncology, hematology, immunology, internal medicine, or infectious diseases, which will certainly have a major impact on clinical medicine in the near future. Nowadays, educational process is forced to face the…

Wagoner, Kasey; Hynes, K. Mairin; Flanagan, Daniel – Physics Teacher, 2018
Introductory physics labs often focus on a series of common experiments intending to teach the student the measurement side of physics. While these experiments have the potential to be quite instructive, we observed that our students often consider them to be boring and monotonous, which often leads to them being uninstructive. To combat this, we…

Kevin Morgan – Journal of Chemical Education, 2023
Practical classes are an important and essential part of undergraduate programs in Chemical Engineering, as each experiment provides an opportunity to reinforce the theory of discrete unit operations that are taught elsewhere in the course. While an expensive pedagogical method, when practical sessions are delivered well, they can be one of the…

Budner, Drew; Simpson, Brett – Journal of Chemical Education, 2018
Students entering into a quantitative analysis course often struggle with connecting theoretical aspects of concepts from lecture to hands-on applications in the laboratory setting. A one-semester quantitative analysis course was redesigned to integrate active learning with a project-based curriculum that incorporated structured review of…

DeFrancesco, Heather; Dudley, Joshua; Coca, Adiel – Journal of Chemical Education, 2018
An undergraduate experiment for the organic laboratory is described that utilizes microwave heating to prepare 5- substituted 1H-tetrazole derivatives through a (3 + 2) cycloaddition between aryl nitriles and sodium azide. The reaction mixture is analyzed by thin layer chromatography. The products are purified through an acid-base extraction and…

Toews, Carl – PRIMUS, 2017
Inquiry-based pedagogies have a strong presence in proof-based undergraduate mathematics courses, but can be difficult to implement in courses that are large, procedural, or highly computational. An introductory course in statistics would thus seem an unlikely candidate for an inquiry-based approach, as these courses typically steer well clear of…

Hati, Sanchita; Bhattacharyya, Sudeep – Biochemistry and Molecular Biology Education, 2016
A project-based biophysical chemistry laboratory course, which is offered to the biochemistry and molecular biology majors in their senior year, is described. In this course, the classroom study of the structure-function of biomolecules is integrated with the discovery-guided laboratory study of these molecules using computer modeling and…

Jensen, Mark B. – Journal of Chemical Education, 2015
An instrumentation-based laboratory curriculum combining traditional unknown analyses with student-designed projects has been developed for an introductory analytical chemistry course. In the first half of the course, students develop laboratory skills and instrumental proficiency by rotating through six different instruments performing…

Kafadarova, Nadezhda; Sotirov, Sotir; Milev, Mihail – Online Submission, 2012
Technology nowadays enables the remote access to laboratory equipment and instruments via Internet. This is especially useful in engineering education, where students can conduct laboratory experiment remotely. Such remote laboratory access can enable students to use expensive laboratory equipment, which is not usually available to students. In…

Knutson, Kristopher; Smith, Jennifer; Wallert, Mark A.; Provost, Joseph J. – Biochemistry and Molecular Biology Education, 2010
A successful laboratory experience provides the foundation for student success, creating active participation in the learning process. Here, we describe a new approach that emphasizes research, inquiry and problem solving in a year-long biochemistry experience. The first semester centers on the purification, characterization, and analysis of a…
