Collaboration TPS Learning Model and m-Learning Based on Android for Understanding of Trigonometry Concepts with Different Cognitive Style

This research aimed to examine the effect of collaboration Think Pair Share (TPS) Leaning Model and m-Learning based on Android on the understanding of trigonometry concepts and to investigate the interaction between collaborative learning and cognitive style on the understanding of trigonometry concepts. This research involved 80 pre-service teachers of Mathematics Department at STKIP Santu Paulus Ruteng, Province of East Nusa Tenggara, Indonesia. The quasiexperimental research with control class without pre-test was done. Before the experiment, the Group Embedded Figures Test (GEFT) was used to identify students cognitive styles either Field-Dependent (FD) or Field-Independent (FI). The research data were obtained from a test consisting of five questions to measure students' understanding of trigonometry concepts. The data were then analyzed using two-way ANOVA. The results of the research show that 1) the collaboration of TPS Leaning Model and m-Learning based on Android leads to the higher achievement of the students on the understanding of trigonometry concepts if compared to students in conventional groups (expository). 2) there was no interaction effect between the collaborative learning and cognitive style of students' understanding of trigonometry concepts.
