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…

Alexander Grushow – Journal of Chemical Education, 2022
A revised version of a traditional physical chemistry laboratory experiment has been developed to enhance student discussion in the laboratory and to improve students' connections between physical chemistry concepts and real molecular systems. In this experiment, students explore the keto-enol tautomerization of 2,4-pentanedione. However, unlike…

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…

Goeltz, John C.; Cuevas, Lia A. – Journal of Chemical Education, 2021
Acid-base titration laboratories are perennially offered to general chemistry students in preparation for summative assessments of their hands-on and quantitative skills in the field. Here, we present a guided inquiry-based activity focused on total titratable acidity (TTA) as alternative to standard "cookbook" titration laboratory work.…

Vlaardingerbroek, Barend – School Science Review, 2018
The role of the school science laboratory, once taken for granted as verification of taught theory using prescribed ('cookbook' to critics) practical activities, has become less clear since the emergence of the 'inquiry' paradigm in which the school laboratory would appear to become a make-believe science research laboratory. But a school science…

Periyannan, Gopal R. – Biochemistry and Molecular Biology Education, 2019
Technique-centered biochemistry or molecular biology undergraduate laboratory curricula do not offer significant opportunities for thoughtful, in-depth exploration of the science to foster investigative learning. To demonstrate inclusion of inquiry-driven laboratory experiments into the undergraduate biochemistry and molecular biology curricula, a…

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…

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…

Tran, Trinh-Ba; van den Berg, Ed; Ellermeijer, Ton; Beishuizen, Jos – Physics Education, 2018
Research has shown that the objectives for laboratory teaching--just as with other teaching methods--are often not achieved and that many laboratory sessions are ineffective and yet expensive in terms of pupil and teacher time, and facilities. There are several reasons for this, but one reason is that instructions for many lab activities are too…

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…
