The Efforts to Improve Mathematical Communication and Self Regulated Learning of Students By Using the Guided Discovery Method in Class X. IS3 SMAN 2 Sungai Limau

Communication skills self-regulated learning mathematics are needed. Mathematical communication is a higher-order thinking skill about math ideas, either oral or written. Meanwhile, self-regulated learning is one's ability to manage oneself in learning, can measure the level of achievement, and determine follow-up if it increases failure. In fact, communication skills and self-regulated learning mathematics of the students are still low. One effort to improve the students' communication skills and self-regulated learning is by using the guided discovery method in the mathematics learning process. The purpose of this study is to describe the improvement of communication and self-regulated learning of students' mathematics learning by using the guided discovery method in learning mathematics. This research is a kind of classroom action research. The subjects of the study were students of class X. IS3 of SMA Negeri 2 Sungai Limau, Sungai Limau District. The technique of collecting data through observation, tests, field notes, and documentation. Data analysis techniques include data reduction, data presentation and conclusions. The results showed an increase in communication skills seen from: the average communication skills of participants reached 60, in the first cycle increased up to 65.30, and in the second cycle also increased up to 70.50. While the increase in mathematics self-regulated learning of the participants can be seen from: the average level of mathematics self-regulated learning of students in class X. IS.3, which early only 65.9% in the sufficient category, in the first cycle it rise up to 69.8% still in the sufficient category, and in the second cycle rise up to 74.35% with a good category. Based on the description above, concluded that the application of guided discovery methods improves the students' communication skills and self-regulated learning in mathematics.
