Pengaruh Metode Improve terhadap Kreativitas Kemampuan Komunikasi Matematis dan Hasil Belajar Siswa Kelas VII A MTS Syekh Subakir pada Materi Bangun Datar

Mathematics is one of the disciplines learned and taught at the education level from elementary school to college. This is because mathematics is one of the basic science that must be mastered by each student to be equipped with logical, analytical, systematic, critical and creative thinking ability and cooperation (Depdiknas, 2006: 153). This study aims to determine whether there is influence Improve Learning Method on creativity of mathematical communication skills and learning outcomes for students of class VII A Mts Sheikh Subakir 01 Nglegok Blitar. IMPROVE learning method is an acronym of Introducing, the new concept, Matacognitive questioning, Practicing, Reviewing and reducing difficulties, Obtaining mastery, Verification, and Enrichment. The population of this study are all students of class VII A Mts Sheikh Subakir 01 Nglegok Blitar. The sample in this study was taken with the Random Sampling Cluster Technique with many students 32 as the control class and experimental class. The design of this research is True-Experimental Design form Posttest-Only Control Derign. The average of categorical test of students' mathematical communication ability in control class is 80,03 with standard deviation of 10.918 experiment class is 86,25 with standard deviation 6,951. The average of student learning outcomes in the control class is 79.44 with standard deviation of 10,531 and experimental class equal to 87,91 with standard deviation of 7,498. The value of significance of learning model of Improve Method, x, to cratification of mathematical communication ability (y_1) is 0,009 <0,05. This means that the learning model of Improve Method, x, influences the creativity of mathematical communication skills (y_1). It can be concluded that the creativity of students' mathematical communication ability of the control class is better than the cratification of the mathematical communication ability of the experimental class. As for the significance value of the Improve, x, method of learning towards student learning outcomes (y_2) of 0.000 <0.05. This means that learning model of Improve Method, x, has an effect on student's learning result (y_2). It can be concluded that the learning outcomes of the experimental class students are better than the student's learning outcomes of the control class.
