This study presents the qualitative and quantitative evaluation of an educational programme that combines an online game and an outdoor activity with mobile learning in science education. The object of the study is to test the capacity of the programme to integrate science, culture and the environment, while transferring knowledge about marble. To this end, we align our theoretical orientation with the overall project design to devise an initial scheme that is pilot-tested by 155 university students of early childhood education and evaluated through a questionnaire. Qualitative data through participants’ feedback after the programme, observation notes and data from video recordings supplement the overall assessment. The results show high levels of satisfaction among the participants in terms of the quality of the activities, the distance between stations, the duration and structure of the programme, contact with marble, and the knowledge acquired.
