The application has to provide contents and assessments in a way that is attractive to the user and digested enough to be used in a short time frame while waiting for friends or buses but also can be used for a full review of the materials. Trigonica introduces the concepts of trigonometry in three short lessons with hand-on activities. The learner can take a dynamic quiz after each lesson and also a comprehensive quiz. The user can also share their experience with his or her community via Facebook posts after finishing a quiz.Mahidol UniversitySocial SciencesConference PaperSCOPUS
