Abstract: This article has the purpose to show principal challenges that teachers deal with and have the intention to transit from a traditional teaching practice to a constructivist teaching practice. In conclusion, this sort of transition is not easy and those teachers would keep teaching on constructivism because we consider this last teaching model has more advantages than traditional teaching so as to increase the learning and is more human in order to set students in the core of the process teaching learning and helping them so that foster their potentialities.
