Abstract

Tujuan penelitian ini untuk mengetahui apakah pembelajaran tersebut terimplementasi dengan baik yang ditandai dengan 1) tuntas pada prestasi belajar, 2) prestasi belajar kelas eksperimen lebih baik dari pada prestasi belajar kelas kontrol 3) keaktifan belajar siswa berpengaruh positif terhadap prestasi belajar siswa. Penelitian ini merupakan penelitian eksperimen. Pengumpulan data  dilakukan menggunakan metode dokumentasi, metode tes, dan metode observasi. Analisis data meliputi analisis data awal dan analisis data akhir. Hasil penelitian menunjukkan bahwa menurut uji statistik rata-rata prestasi belajar  pembelajaran pada siswa kelas eksperimen 78,88 tuntas secara individual dan klasikal, secara uji statistik rata-rata prestasi belajar siswa kelas eksperimen lebih tinggi daripada rata-rata prestasi belajar siswa pada kelas kontrol. Dari hasil analisis regresi, diperoleh persamaan regresi linier sederhana sebagai berikut . Koefisien determinasi menunjukan bahwa hasil tes prestasi belajar siswa 46,3% dipengaruhi oleh keaktifan, sedangkan sisanya sebesar 53,7% dipengaruhi oleh faktor lain.The purpose of this study were to determine whether the study was well implemented if 1) student reach mastery learning, 2) experimental class learning achievement was better than the control class learning achievement 3) active learning had a positive effect on students' learning achievement. This research is an experiment research. The data was collected by documentation method, test method, and observation method. Data analysis includes Initial data analysis and final data analysis. Results showed that according to statistical calculation the average of learning achievement in experiment class students was 78.88, students had reached students mastery learning in individual and classical. the average of students’ achievement in experiment class was higher than the average of students’ achievement in control class. From the results of the regression analysis, gained a simple linear regression equation as follows: Y = a + bX = 28.206 +1.741 X. The coefficient of determination indicated that students’ achievement results were influenced by the students’ activity of 46.3%, the rest 53.7% was influenced by other factors.

Abstract

This study aims to find out whether: (1) self efficacy mathematics of students who are taught by the learning model of Treffinger oriented local wisdom with better-tiered assignment or not from self efficacy of students receiving conventional learning, (2) students' mathematics student competence taught by model Lessons are used to perform better or better tasks from students receiving conventional learning, (3) there is some self-efficacy and simultaneous mathematical strategies between students who are taught by Treffinger-aided learning model with tiered assignments conventional learning. This research type is quasi experiment with posttest only control group design. Data in this research is self efficacy mathematics used by using questionnaire and data required by student. The data obtained were analyzed descriptively on the basis of t-test 1 for hypothesis 1 and hypothesis 2, and MANOVA test for hypothesis 3. Characteristics of the teaching-oriented model of Treffinger oriented local wisdom with the help of this tiered function are: (1) student involvement in the problem and they as participants active in problem solving, (2) the science of cognitive dimension and student affectivity to seek the direction of problem solving provided, (3) the students do group analysis to explore ideas, and (4) the students use the acquired understanding to solve other related problems with everyday life. In addition, by delivering advice sourced from Bali's reliable local wisdom and making the process more enjoyable. Given tiered tasks in learning mathematics such as practice questions that can be done effectively. Through the learning model oriented Treffinger local wisdom assisted by this tiered task is expected students are able to solve problems in a way with their own. The process of thinking to discuss mathematical problems and will foster confidence in students to solve problems related to other terms for the next. To complete the problem of tiered training well, also required good students also.

Abstract

Masyarakat dapat dipersepsi sebagai sebuah ruangan kelas dan sekolah dapat dipandang sebagai representasi sebuah masyarakat; tempat murid, guru dan orang tua menciptakan definisi sebuah sekolah masyarakat. Di dalam masyarakat dimungkinkan terjadi miskonsepsi, namun demikian, miskonsepsi yang terjadi dan bersumber dari masyarakat dapat  “disembuhkan” menggunakan instrumen-instrumen yang tersedia di masyarakat. Telah terjadi miskonsepsi di komunitas siswa dan guru di jenjang SD, p = 22/7. Secara konseptual, nilai p merupakan perbandingan keliling dan diameter suatu benda yang berbentuk lingkaran. Melalui kegiatan pengukuran benda-benda berbentuk lingkaran yang tersedia cukup melimpah di lingkungan sekitar, kemudian membandingkannya dengan diameter, kesalahan Siswa di dalam memahami konsep  dan penerapannya melalui diskusi kelompok kecil, dapat direduksi sebesar 80%.
