Disseminating Scientific Knowledge Using Chemistry Teaching: Exemplified by the Chemical Principles of Fingerprint Manifestation

Fingerprint can be widely acknowledged as the "first evidence" of forensic science, in which fingerprint manifestation is the first and also the most important step to discover latent fingerprint. Flipped classroom and team-based learning modes have been implemented in the chapter of "chemistry and criminal science and technology" of Chemistry and Society course. Students were encouraged to consult relevant references in advance and participated in the team discussion in class. Herein, the fingerprint is personified into a "mysterious thief" with multiple faces, while various fingerprint display technologies are personified into investigators of the fingerprint department. Collectively, this teaching strategy can popularize the chemical principles of several fingerprint techniques to students, enrich their scientific understanding of the fingerprint display technology, and improve their scientific quality and learning interests.
