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…

Tsaparlis, Georgios; Gorezi, Marianna – Journal of Chemical Education, 2007
Students should enjoy their laboratory classes and for this purpose a project-based activity is added to a conventional physical chemistry laboratory. Students were given project work instead of conventional experiment and then they had to make progress in the project according to instructions and then carry out experiments related to the project.

Kirschner, P. A. – 1989
The Prime Minister's Committee on Natural Science in Education in Great Britain reported in 1918 that "...in many schools more time is spent in laboratory work than the results obtained can justify." Seventy years later this conclusion can often still be drawn. This is particularly a problem in open distance education where laboratory practicals,…
