Meningkatkan Kemampuan Komunikasi Matematis Melalui Strategi Every One Is A Teacher Here Dengan Pendekatan Metakognitif Siswa SMA

This study investigated the improvingof students’mathematical communication skill between the ones who has been taught using Every One is a Teacher Here (ETH) as learning strategy with Metacognitive Approach (PM), with the students who learned mathematics in their usual learning style, in terms of students’ initial math ability (superior and inferior) as well overall aspects. The method used in this study was embedded designtype of mixed methods. The findings of this study indicates that 1) The mathematical communication skill of students who applied Every One is aTeacherHere(ETH) with Metacognitive Approach (PM) has been improved better than students who applied regular learning (PB) in terms of Students’ Initial Mathematical Ability Category (superior and inferior), 2) The mathematical communication skill of students who applied Every One is a TeacherHere(ETH) with Metacognitive Approach (PM) has been improved better than students who applied regular learning (PB) in terms of overallaspects.
