DONOSO-TAUDA, Oscar Ricardo; PALMA VALENCIA, Andrés; ROJAS POBLETE, Macarena  and  URRUTIA MENDEZ, Jaime. Teaching of the basic concepts of High-Performance Liquid Chromatography (HPLC) with a collaborative and linked learning approach: determination of acrolein in cigarette smoke. Educ. quím [online]. 2019, vol.30, n.3, pp.15-23.  Epub Nov 30, 2019. ISSN 0187-893X.  https://doi.org/10.22201/fq.18708404e.2019.3.69368.

This article presents a project-based activity, which corresponds to a contextualized (linked) laboratory experience that uses the scientific method performed with students of the undergraduate program “Tecnología en Análisis Químico” (TAQ) at “Universidad Tecnológica de Chile, INACAP” and whose emphasis was to contribute to the theoretical-practical learning of basic concepts of the High Performance Liquid Chromatography (HPLC) using the project based learning (PBL) through the implementation of an analytical method for the determination of chemical substances from “real-life products”. In this case, the students participated directly and actively in all the stages that allowed to estimate the concentration of acrolein, a highly toxic compound contained in cigarette smoke, acquiring in the process the fundamental skills of this instrumental analysis technique, which is a tool widely used in the work area of the chemical analyst.

Finally, our main objective is to carry out a practical laboratory activity focused on the chemical contextualization in order to promote effective learning, linking students in a broad social context beyond the classroom or laboratory, taking advantage of the intrinsic motivation that a significant activity can generate.

Keywords : Project based learning (PBL); Contextualization; Acrolein; Smoke- cigarette; HPLC.
