An alternative to teach chemistry laboratories in Municipal University Centers (Original).

Abstract

With the municipalization of Higher Education in Cuba, in the Municipal University Centers (MUC) careers with an agricultural profile are taught. Among these is the Agricultural Engineering, which is studied in the 9 municipalities of the Santiago de Cuba province. In Plan E, the career contains two subjects within the Chemical Discipline, which constitute the basis of the chemical processes that future agronomists study. One of the forms of teaching to teach chemistry is constituted by laboratories, which allow to verify experimentally what is received in theory. In the MUC, the teaching of the laboratories is difficult due to the lack of the appropriate infrastructure, so the objective of the work is to show an alternative to teach the chemistry laboratories in the MUC. This consists of presenting the students with a video obtained from YouTube, which contains a laboratory practice that they must observe and answer a guide of questions that will be evaluated. A laboratory practice guide related to the chemical properties of aldehydes and ketones is presented, using the video as a teaching method. The advantages of teaching the laboratories in this new way are exposed, as well as the experiences in the MUC of "III Front", concluding that teaching with videos constitutes an innovative didactic strategy that can be used as an alternative for teaching chemistry laboratories in MUC.
