This study’s objective was to evaluate a MOOC constructed from educational principles based on behavioral theory. The evaluation included the analysis of the performance, retention, and perception of the students. This MOOC consisted of an initial test, three teaching units, a final test and an assessment of the students' perception. The mean grade in the initial test was 6.34 (sd=1.20), and in the last attempt of the final test it was 8.75 (sd=0.51). The difference between these values was statistically significant and the effect size was considered very large. The retention rate was 44%, and 75% of students rated the overall experience as “Very Good”. The evaluated MOOC was effective in teaching its learning objectives and student retention was much higher than the average reported in other studies.These results indicate the relevance of the educational principles used in the elaboration of the MOOC.
