Penggunaan jurnal reflektif pada pembelajaran Matematika untuk melatih kemampuan komunikasi matematis siswa

Many students have difficulty learning mathematics, but the teacher does not have much information, so the teacher cannot provide the best solution. The purpose of this study was to describe student responses, student learning outcomes, and to describe students' mathematical communication skills in mathematics learning using reflective journals. The research method used is descriptive with a qualitative and quantitative approach with the subject of class VII-E students at SMPN 6 Sidoarjo. The instruments used include student response questionnaires, learning outcomes tests, and interviews. Data analysis on communication skills (written, oral) was obtained from the scores obtained by each subject based on written and oral mathematical communication rubrics, then determined the level of students' mathematical communication skills. Based on the results and discussion, it was found that the completeness of student learning outcomes was 75% (mean 78.6), student responses were good (3.36), students' mathematical communication skills were low, medium, and high at levels 3, 4 and 5 respectively. reflective in mathematics learning can train mathematical communication skills and student learning outcomes.
