Being a teacher is much more that delivering contents in the classroom. It implies setting standard behaviors as well as showing ways to work. In one word, teachers are an example in the classroom. The implementation of their way to teach will be considered as good or bad teaching by their own students for many years. Likewise, the way they use technology in the classroom can trigger motivation and perceptions in their future students. That is why, teachers need to be conscious of what they do in the classroom and adopt technology principles to be applied in a near future. This paper addresses how teachers do that at Universidad de Alcalá (Madrid, Spain). The paper shows the main work done in class and considers the effect in the short and long run.
