Beck, Rachel C.; Erdmann, Mitzy A. – Journal of Chemical Education, 2018
Identification and quantification of an unknown illicit drug (cocaine) from both simulated drug paraphernalia and simulated urine can be achieved via direct analysis in real time (DART) triple quadrupole linear ion trap (QTRAP) mass spectrometry (MS). We describe a novel, hands-on laboratory activity which utilizes the recent DART technology…

Michelle, Richards-Babb; Curtis, Reagan; Ratcliff, Betsy; Roy, Abhik; Mikalik, Taylor – Journal of Chemical Education, 2018
We investigated whether use of an adaptive-responsive online homework system (OHS) that tailors homework to students' prior knowledge and periodically reassesses students to promote learning through practice retrieval has inherent advantages over traditional-responsive online homework. A quasi-experimental cohort control post-test-only design with…
