Under normal conditions, at the Tecnoacademia we do training at our facilities. However, due to the pandemic caused by COVID-19, during the first semester of 2020, we generated a strategy called “challenges” in order to encourage learners to continue with our courses. For this, each line developed three challenges taking into account that they were associated with theoretical concepts of the area and that an apprentice could develop them with materials that were available at home, which were low cost and easy to acquire. In this booklet we present six modules with the challenges generated by the training lines. In these, we highlight the best results obtained by the apprentices enrolled in our program, where creativity and innovation are the protagonists. For reasons of space, we only included three, but all the solutions presented were surprising. For this reason, we invite you to build your own solutions.
