Development of mobile learning with constructive models in trigonometry material at senior high school 8 in Semarang

This research is motivated by the non-optimal increasing use of smartphones among students with the aim of developing a mobile learning media on the subject of trigonometry using a decent constructive model for an interactive and effective mathematical teaching process. Data were effectively analyzed using the Research and Development (R&D) methods with the Borg and Gall model. The product showed that the effective criteria of the experimental class learning achievement were better than the control class using the t-test. The obtained t count> t table is 2,09 > 1.67. Therefore, Ho is rejected, which means learning using media mobile with the constructivist model is better than the conventional. Therefore, it is concluded that mobile learning media with the constructivist model is an effective learning process for senior high school student
