Strategy for the strengthening of scientific competencies in theteaching of chemistry

Resumen en inglés

Abstract –Scientific competencies are related to inquiry, argumentation and explanation processes. Itsstrengthening allows the understanding of nature and the environment. The objective of the study is toimplement an educational strategy for the strengthening of scientific competencies in the teaching ofchemistry. The methodology is mixed with the performance of laboratory activities. The sample is made up of33 students of eleventh grade of an educational Institution located in a rural area of Colombia, who don’t havetechnological resources (cellphone, computer, internet, among others). The data collection comes from aquestionnaire of natural sciences (chemistry) that served as pre-test and post-test, a script of open questionsand the activities developed in class and experiments. It is concluded that by implementing the didacticsequence it was possible to generate changes in the teaching of science and strengthen scientific thinkingthrough experimentation in the classroom. It is recommended a cross-cutting approach of scientific thinkingin subjects such as physics, biology and chemistry
