Peningkatan Kemampuan Pemahaman Matematis Siswa melalui Pembelajaran Kooperatif Teknik Kancing Gemerencing dan Number Head Together

Abstract

The method that used of this research is quasi experiment make use of two classes, quasi experiment I and quasi experiment II. The population is all of sevent grade students at SMPN 5 Garut period 2014/2015, and the sample is H-sevent grade as quasi experiment I who get kancing gemerincing learning and F-sevent grade as quasi experiment II who get NHT learning with purposive sampling. The purposive sampling is sampling based on certain considerations. The instrument of this research is mathematical understanding skill test and questionnaire. Based on the result of research, known that: (1) found the difference increased of mathematical understanding skill students between who get strategy cooperative learning technique Numbered Head Together (NHT) and kancing gemerincing, (2) the increased quality of mathematical understanding skill quasi experiment I students with technique kancing gemerincing is enough, (3) the increased quality of mathematical understanding skill quasi experiment II students with technique NHT is enough, (5) the student were gived their positive attitude to technique kancing gemerincing, (5) the student were gived their positive attitude to technique NHT, but they were gived their negative attitude to equipping of LKS
