Comprehensive educational model based on Challenge-Based Learning for the improvement of competency performance

[EN] "Insanity is doing the same thing over and over again and expecting different results". This phrase, attributed to Albert Einstein, contains a message that sums up what is happening in education systems. Fortunately, an increasing number of "madmen" are choosing to do something different to "innovate" in the teaching-learning process. This paper shows the influence of innovating in four key aspects that influence learning: instruction, methodology, space and time, if we want to improve competence performance and start to make the objectives of the Bologna Declaration a reality, through experiences carried out in the School of Industrial Engineering (EII) of the University of Extremadura.
