Abstract

Tujuan penelitian ini adalah untuk menghasilkan media pembelajaran matematika virtual berbasis TGT yang berkualitas baik dan layak untuk digunakan dalam pembelajaran matematika dan mendeskripsikan seberapa baik kualitas perangkat pembelajaran matematika yang dihasilkan. Kriteria kualitas yang digunakan mengacu pada kriteria Nieveen, yaitu valid, praktis dan efektif. Materi yang dikembangkan adalah materi Bangun Ruang Sisi Datar. Jenis penelitian ini adalah penelitian pengembangan (Development research). Penelitian ini mengembangkan perangkat pembelajaran matematika dengan menggunakan model pengembangan yang diadaptasi dari model pengembangan ADDIE. Tahap-tahap yang dilalui sampai diperoleh multimedia pembelajaran matematika yang valid, praktis dan efektif adalah analisis kebutuhan dan perumusan tujuan, desain/pengembangan produk, uji coba, revisi dan kajian produk akhir. Uji coba yang dilakukan meliputi ujicoba ahli/validasi ahli (expert judgement), uji coba kelompok kecil (small group try-out) dan uji coba lapangan (field try-out). Uji coba lapangan (field try-out) dilakukan pada dua kelasVIII di SMP N 1 Sedayu. Instrumen penelitian yang digunakan adalah lembar validasi, lembar penilaian guru, lembar penilaian siswa, dan tes Cognitive Load Theory (CLT). Penelitian ini menghasilkan media pembelajaran matematika virtual yang berkualitas dan layak. Hasil penelitian menunjukkan bahwa multimedia pembelajaran matematika yang dikembangkan valid, praktis dan efektif.

Abstract

Cooperative learning is the type of Teams Games Tournament (TGT) which is a learning model in which there are stages such as games which can make the students communicate mathematically, more creative, have a positive attitude towards mathematics, and appropriate in solving mathematical problems. But in fact, communication skills and problem solving that should be owned by the students as a result of the learning process of mathematics meet the minimum completeness criteria (KKM). This study aims to describe the effectiveness of Cooperative learning of TGT type at mathematics learning in terms of communication skills and problem solving in class VIII SMP N 1 Seyegan the school year 2016/2017.  This research is a quasi ekspreriment research with pre-posttest nonequivalent control group design. This study uses two groups: the experimental group and the control group. The population study includes all students of class VIII which consists of four classes. From the existing population, it is drawn randomly two classes, namely VIII A and VIII C as samples. Mathematics Learning in class VIII A (experimental group) uses TGT type Cooperative learning and mathematics learning in class VIII C (control group) uses direct instruction. The instrument of this study is testing the communication and problem solving capability. To test the effectiveness of the study, it is used the analysis of one sample t-test. Whereas the T2 test hotteling is foolowed by univariate t-test which is used to determine more effective model. The result of research indicates that: (1) Cooperative learning of TGT-type and direct instruction in mathematics is effective in terms of communication skills and problem-solving; and (2) Cooperative learning of TGT type is more effective than direct instruction type in term of communication skill in class VIII SMPN 1 Seyegan. Keywords: TGT, mathematical communication, problem solving

Abstract

This research aims to: (1) describe the implementation of learning mathematics with Reciprocal Teaching methods that is for improving the concept of learning understanding mathematic in class VIIA SMP Negeri 2 Depok. (2) Knowing the increased understanding of student learning in class VIIA SMP Negeri 2 Depok use Reciprocal Teaching methods. This research constitutes an action in class that is according along the teacher. The data of research was collated by sheet observations and each evaluation of cycles. That is done in two cycles. The first was retrieved the average value of student learning achievement of 70.96%. The second was retrieved achievement of 90.32%. Thus this learning model can increase student learning understanding. Key word: The understanding of Mathematical Concept, Reciprocal Teaching Method.

Abstract

The goals of this research are: (1) To describe the implementation of mathematics learning with realistic mathematics learning approach Indonesia (PMRI) in efforts to improve learning achievement of students in grade VII E SMP Negeri 1 Sayegan (2) describe the improvement of student achievement in mathematics graders VII E SMP Negeri 1 Sayegan through a realistic approach to learning mathematics Indonesia (PMRI). This research is a classroom action research conducted collaboratively with teachers. Subject of research is 32 students in grade VII E SMP Negeri 1 Sayegan. Collecting data using observation sheets, and about the avaluation of each cycle. The study was conducted in two cycles, the implementation of the first cycle obtained an average value of student achievement amounted to 83.00%, the second cycle obtained value student achievement by 93, 65%. Thus PMRI approach can improve student achievement.Keywords: Implementation Indonesia Mathematics Realistic Learning Approach(IMRL), learning achievement, mathematics Subjects.
