Interest in using mobile applications to enhance students' learning in Spanish classrooms runs high; however, little empirical research about their effects has been conducted. Using intentionally designed classroom activities to promote meaningful learning with a mobile application, we investigated the extent to which students of Spanish as a second language (L2) could improve accuracy in conjugating verbs. Pre- and posttest results show that these activities helped students improve not only accuracy but also confidence in conjugating Spanish verbs. The 80 students who participated in this study for four consecutive semesters reported an overall positive experience with the verb-conjugating activities but noted some limitations. Results of this empirical study enhance the learning of Spanish with a mobile application in the classroom.
