Mobile technologies constitute a didactic resource with great potential. However, their incorporation process to the classroom is not being implemented in a satisfying way. The future teachers will play a key role in the integration process of these technologies’ integration process in formal education contexts and, therefore, it is essential to know the factors that condition their decision-making process.This article presents the results of a research which analyzes the influence of motivational factors on the behavioral intention to use mobile technologies in the future teaching practice of the students from the Pre-primary Education Degree from the University of Salamanca. With this purpose, we have developed a TAM-based technology adoption model including the following constructs: perceived usefulness, perceived ease of use, perceived enjoyment, resistance to change and behavioral intention. The employed PLS-SEM analysis confirms the validity and reliability of the model. The results of the analysis of the structural model reflect the importance of perceived enjoyment and perceived usefulness in the adoption process, as well as the low relevance of perceived ease of use. In total, the motivational factors enable the prediction of a high percentage of the variance of behavioral intention, which reveals the need to design educational programmes that emphasize on these elements.
