4.2. Comparative study
According to the literature (Furió, González-Gancedo, Juan, Seguí, & Rando, 2013), comparing new m-learning proposals with traditional methods seems to be a common approach to evaluating their effectiveness. Following this trend, we conducted a controlled experiment during the next academic year (2012/13) to further evaluate our proposal from an objective point of view. It consisted of a crossover posttest to determinate whether the proposed 3D m-learning tool had a better learning outcome than the traditional methods.
