The objective of this research is to evaluate the effect of a didactic strategy that integrates remote laboratory practices on the subject of electrical circuits to promote the development of critical thinking in engineering students from a state university in Ecuador. It is design-based research that combines both quantitative and qualitative methodologies divided into two interventions; here we present the first intervention in which a teacher and 60 subjects between 18 and 20 years of age participated. The design of the didactic strategy included readings, open and closed questions and carrying out experimental practices with a remote laboratory. Two tests were applied to determine the levels of development of critical thinking and the level of learning achievement of the studied subjects: at the beginning, prior to the design and application of the strategy, as a diagnostic evaluation and at the end, after applying the didactic strategy. Comparing the results of both tests at the beginning and at the end of the application of the didactic strategy, it was found that 33 subjects increased their level of critical thinking by at least 1 point, a result validated with the Wilcoxon test, and 38 subjects increased their level of learning achievement by at least 1 point, a result validated through the Hake gain, which corresponds to 61 % and 63 % respectively of the total sample. As a result of the application of the didactic strategy, of the 60 subjects in the sample, 23 (38 %) significantly improved both the development of critical thinking and learning.
