Abstract

ABSTRAK Penelitian ini bertujuan untuk menganalisis peningkatan aktivitas siswa pada pembelajaran matematika menggunakan media kubus satuan pada siswa kelas VB SD Negeri 81 Kota Bengkulu dan mendeskripsikan penggunaan media kubus satuan yang tepat sehingga dapat meningkatkan aktivitas siswa pada pembelajaran matematika. Subjek penelitian ini adalah siswa yang berjumlah 29 orang. Teknik pengumpulan data menggunakan metode observasi, wawancara dan dokumentasi. Data yang dikumpulkan dalam penelitian ini adalah data observasi aktivitas siswa dan aktivitas guru. Teknik analisis data menggunakan analisis deskriptif kualitatif. Hasil penelitian ini menunjukkan peningkatan aktivitas siswa kelas VB pada pembelajaran matematika, hal ini dibuktikan oleh adanya peningkatan aktivitas belajar siswa pada siklus II, pada siklus I, hanya sebagian kecil siswa yang aktif dalam mengikuti pembelajaran, masih terdapat beberapa aspek aktivitas siswa yang belum muncul, yaitu pada kegiatan inti aspek menciptakan aktivitas berpikir, aktivitas praktik, interpretasi, dan mengkreasi, pada siklus II, indikator keberhasilan penelitian sudah terpenuhi, sebagian besar atau lebih dari 15 orang siswa sudah melaksanakan aktivitas pembelajaran pada kegiatan pembuka, kegiatan inti, serta kegiatan penutup dengan sangat baik. Penggunaan media kubus satuan yang tepat untuk meningkatkan aktivitas siswa pada pembelajaran matematika adalah dengan sistem pembagian siswa berkelompok dengan kelompok kecil, pemberian motiviasi, dan apresiasi. Dengan demikian, penggunaan media kubus satuan yang tepat dapat meningkatkan aktivitas siswa kelas VB SD Negeri 81 Kota Bengkulu pada pembelajaran matematika. Kata kunci          : media kubus satuan, aktivitas siswa, pembelajaran matematika This research aims to analyze the increase in student activity in mathematics learning using unit cube media for students of grade VB SD Negeri 81 Bengkulu City and describe the use of unit cube media that is appropriate so that it can increase student activity in mathematics learning. The subjects of this study were 29 students. Data collection techniques use observation, interview, and documentation methods. The data collected in this study are observation data of student activities and teacher activities. Data analysis techniques used qualitative descriptive analysis. The results of this research indicate an increase in the activity of VB class students in mathematics learning, this is evidenced by an increase in student learning activities in cycle II, in the first cycle, only a small number of students were active in learning, there were still some aspects of student activity that had not yet appeared, namely in the core activities aspects of creating thinking activities, practical activities, interpretations, and creation, in cycle II, the success indicators of research have been fulfilled, most or more than 15 students have carried out learning activities in opening activities, core activities, and closing activities with very good. The proper use of unit cube media to increase student activity in mathematics learning is by a system of division of students in groups with small groups, giving motiviation, and appreciation. Thus, the use of the right unit cube media can increase the activity of grade VB SD Negeri 81 Bengkulu students in mathematics learning. Key words           : unit cube media, student activities, mathematics learning

Abstract

ABSTRACTThis research aims to analyze the increase in student activity in mathematics learning by applying cooperative learning model type STAD to VB grade students of SDN 81 Bengkulu City, and to describe the application of the right STAD type cooperative learning model so as to increase student activity in mathematics learning. The subjects of this study amounted to 29 people. Data collection techniques use observation and documentation techniques. The data collected in this study is the observation data of increasing student activity and data on the implementation of STAD type cooperative learning model in mathematics learning. Data analysis techniques used qualitative descriptive analysis. The results of this study indicate an increase in student activity in learning mathematics in class VB SD Negeri 81 Kota Bengkulu. This is evidenced by the activities of students in learning mathematics has increased in cycle II. In cycle 1 only a small number of students were active in learning and there were still some aspects of student activity that had not yet appeared in the core activities of interpretation and activity evaluating activities, while in cycle II the success indicators had been fulfilled, namely most students carried outPenerapan Model Cooperative Learning Tipe Student Team Achievent Divisionlearning activities or more than ½ (half) the number of students, more than 15 students carrying out learning activities on: opening, core and closing activities very well. The application of the STAD learning model is appropriate to increase student activity in mathematics learning, namely by providing motivation and guidance so that students can actively explore in groups as well as appreciation in the form of rewards. Thus, the application of the appropriate STAD learning model can increase students' activities in the mathematics learning of VB grade students of SD Negeri 81 Kota Bengkulu.Keywords: Student Achievement Team Division, Student Activity, Mathematics Learning.

Abstract

ABSTRAK Penelitian ini bertujuan untuk mengetahui peningkatan kemampuan memecahkan masalah soal cerita matematika menggunakan penerapan model Problem Based Learning (PBL) pada siswa kelas VA SD Negeri 01 Kota Bengkulu dan mendeskripsikan penerapan model Problem Based Learning (PBL) yang tepat sehingga dapat meningkatkan kemampuan memecahkan masalah soal cerita matematika pada siswa. Subjek penelitian ini berjumlah 33 orang. Teknik pengumpulan data menggunakan metode tes dan observasi. Data yang dikumpulkan dalam penelitian ini adalah data kemampuan memecahkan masalah siswa dan data observasi model pembelajaran PBL. Teknik analisis data menggunakan analisis statistik deskriptif dan analisis kualitatif. Hasil penelitian ini menunjukkan peningkatan kemampuan memecahkan masalah soal cerita matematika siswa kelas VA SD Negeri 01 Kota Bengkulu. hal ini dibuktikan dengan nilai rata-rata kelas mangalami kenaikan menjadi 67,7 dengan persentase ketuntasan klasikal sebesar 51,51% pada tes siklus 1. Adapun pada tes siklus 2 nilai rata-rata kelas semakin baik hingga mencapai nilai 82,1 dengan ketuntasan klasikal sebesar 78%. Peningkatan pada siklus 2 telah mencapai indikator keberhasilan yang diharapkan yaitu nilai rata-rata ? 70 dengan ketuntasan klasikal minimal 75% siswa. Dengan demikian, penerapan model pembelajaran PBL yang tepat dapat meningkatkan kemampuan memecahkan masalah soal cerita matematika siswa kelas VA SD Negeri 01 Kota Bengkulu. Kata kunci       : problem based learning, kemampuan memecahkan masalah, soal cerita matematika. ABSTRACT This research aims to determine the improvement of the ability to solve problems of mathematical story problems using the application of Problem Based Learning (PBL) model for VA class students of SD Negeri 01 Bengkulu City and describe the application of the right Problem Based Learning (PBL) model so as to improve the ability to solve story problems mathematics in students. The subjects of this research amounted to 33 people. Data collection techniques used test and observation methods. The data collected in this study was data on student’s problem solving skills and PBL learning model observation data. Data analysis techniques used descriptive statistical analysis and qualitative analysis. The results of this study showed an increase in the ability to solve problems of math story problems of class VA students of SD Negeri 01 Bengkulu City. This is evidenced by the average grade increased to 67.7 with a percentage of classical completeness of 51.51% in cycle 1 test. As for the second cycle test the average grade score was getting better until reached 82.1 with classical completeness of 78%. The increase in cycle 2 has reached the expected success indicator which is an average value of ? 70 with a classical completeness of at least 75% of students. Thus, the application of the right PBL learning model can improved the problem solving ability of math story problems of VA class students of SD Negeri 01 Bengkulu City. Key words        : problem based learning, ability to solve problems, math story problems
