This work addresses the use of tablets and smartphones to enhance both student learning and engagement. Tablets were tested as potential substitutes for digital whiteboards, while smartphones were tested as potential survey media in the classroom using a question and answer method. Two teaching strategies were evaluated and compared: (1) traditional, which includes the use of the blackboard together with PowerPoint presentations and (2) interactive, where lessons are taught with the aid of a tablet, using interactive activities and digital materials. Measures of performance outcomes achieved with these strategies were made using the question and answer method at two points, during the classes and during the end-of-term examination. Three different question and answer methodologies were studied and compared, ranging from the very traditional method where students raise their hand to answer a question to the most modern where students use their smartphones to answer. The findings demonstrated higher outcomes with interactive lessons than with traditional learning (PowerPoint included). Tablets proved to be an effective and cheaper substitute for interactive whiteboards during lessons. The results suggested that the use of interactive procedures increased student participation. Furthermore, the students were very receptive to the use of smartphones as survey media. The use of smartphones as clickers is an interesting and instant way for both teachers and students to check students' learning and perceived engagement. Considering that students are advanced users of smartphones and/or tablets, the use of these may be considered as more convenient than clickers. In addition, it is economically more acceptable than some other audience response systems.
