The ability of students to perform quantitative analysis is a fundamental aspect of analytical chemistry courses and laboratories. In this laboratory experiment, students quantitatively analyze both liquid and solid samples through the use of internal standard calibration and ATR-FTIR spectroscopy. Using a problem-based approach to selecting their…

Hurst, Glenn A. – Journal of Chemical Education, 2017
A laboratory experiment was developed to enable students to investigate the use of smart hydrogels for potential application in targeted drug delivery. This is challenging for students to explore practically because of the extremely high risks of handling cross-linking agents such as glutaraldehyde. Genipin is a safe and green alternative that has…

Whitworth, David E. – Biochemistry and Molecular Biology Education, 2016
Laboratory-based practical classes are a common feature of life science teaching, during which students learn how to perform experiments and generate/interpret data. Practical classes are typically instructional, concentrating on providing topic- and technique-specific skills, however to produce research-capable graduates it is also important to…

Klokocovnik, Vesna; Šorgo, Andrej; Devetak, Dušan – Journal of Biological Education, 2016
One of the innovations in the Slovenian school system has been the introduction of elective subjects in the curricula of primary and secondary schools, thus there is a lack of teaching manuals for practical exercises and hands-on classroom experience. This situation is reflected in the Ethology classroom and for that purpose we prepared…

de los Santos, Desiree´ M.; Montes, Antonio; Sa´nchez-Coronilla, Antonio; Navas, Javier – Journal of Chemical Education, 2014
A Project Based Learning (PBL) methodology was used in the practical laboratories of the Advanced Physical Chemistry department. The project type proposed simulates "real research" focusing on sol-gel synthesis and the application of the obtained sol as a stone consolidant. Students were divided into small groups (2 to 3 students) to…

Hicks, Randall W.; Bevsek, Holly M. – Journal of Chemical Education, 2012
A series of qualitative analysis (QA) laboratory experiments utilizing a problem-based learning (PBL) module has been designed and implemented. The module guided students through the experiments under the guise of cleaning up a potentially contaminated water site as employees of an environmental chemistry laboratory. The main goal was the…
