Dari hasil penelitian yang diberi perlakuan yang berbeda, kelas eksperimen 1 dengan model pembelajaran Discovery Learning dan kelas eksperimen 2 dengan model pembelajaran kooperatif tipe STAD diperoleh kesimpulan bahwa kemampuan penalaran matematis siswa yang diajar dengan model pembelajaran Discovery Learning lebih tinggi daripada siswa yang diajar dengan model pembelajaran kooperatif tipe STAD di kelas VIII SMP Negeri 6 Medan T.A. 2016/2017 Kata Kunci : Discovery Learning, STAD, Penalaran Matematis ABSTRACT This study aims to determine that the students' mathematical reasoning abilities taught by the learning model of Discovery Learning is higher than the students who are taught by STAD type cooperative learning model in class VIII SMP Negeri 6 Medan T.A 2016/2017. This type of research is a quasi experiment. The population in this study is all students of class VIII Semester even Junior High School 6 Medan and the sample in this study are students of class VIII-C and class VIII-D as many as 76 students. The instrument used to determine students' mathematical reasoning abilities is a validated test of mathematical reasoning ability in the form of a description. From the results of different research, experimental class 1 with the learning model of Discovery Learning and experiment 2 class with STAD type cooperative learning model obtained the conclusion that the students' mathematical reasoning ability taught by the learning model of Discovery Learning is higher than the students who are taught by the model of learning Cooperative type STAD in class VIII SMP Negeri 6 Medan TA 2016/2017 Keywords: Discovery Learning, STAD, Mathematical Reasoning
This decision support system is used to select outstanding teachers and is aimed at SD 095130 Senio Bangun which still uses manual system in assessing the candidates of outstanding teachers. So this system is expected to assist the agency in the process of assessment and determination of outstanding teachers in the area of Pematang Siantar City quickly and accurately. The method used in ranking the selection of teachers achieving achievement in this system using AHP method is a method The workings of this method is almost similar to the workings of the brain, namely by elaborating complex problems into more problems that are more structured and systematic. Where alternatives are used as much 4 teachers with job criteria, education, rank / goals / Space and last sk. The results of ranking in this system are influenced by the selection of preference criteria and determinations entered into the system. The test of this system uses data from 45 teachers, ranking divided according to Kindergarten, SD / MI, SMP / Tsanawiyah, SMA / MA, and SMK. Of the several trials that have been done to determine the achieving teacher, the ranking results are much faster and more accountable.
