Direct linkMate, Karen; Sim, Alistair; Weidenhofer, Judith; Milward, Liz; Scott, Judith – Biochemistry and Molecular Biology Education, 2013
A blended approach encompassing problem-based learning (PBL) and structured inquiry was used in this laboratory exercise based on the congenital disease Osteogenesis imperfecta (OI), to introduce commonly used techniques in biomolecular analysis within a clinical context. During a series of PBL sessions students were presented with several…

Corotto, Frank; Ceballos, Darrel; Lee, Adam; Vinson, Lindsey – American Biology Teacher, 2010
Students commonly test the effects of chemical agents on the heart rate of the crustacean "Daphnia" magna, but the procedure has never been optimized. We determined the effects of three concentrations of ethanol, nicotine, and caffeine and of a control solution on heart rate in "Daphnia." Ethanol at 5% and 10% (v/v) reduced mean heart rate to…

Carvalho-Knighton, Kathleen M.; Keen-Rocha, Linda – Journal of Chemical Education, 2007
The effectiveness of two different laboratory techniques is compared to teach students majoring in science in a general chemistry laboratory. The results demonstrated that student laboratory activities with computer-interface systems could improve student understanding.
