Abstract

The students' difficulty which was found is in the problem of understanding, drawing diagrams, reading the charts correctly, conceptual formal mathematical understanding, and mathematical problem-solving. The appropriate problem representation is the basic way in order to understand the problem itself and make a plan to solve it. This research was the experimental classroom design with a pretest-posttest control in order to increase the representation of visual thinking ability on mathematical problem-solving approach with contextual learning. The research instrument was a test, observation, and interviews. Contextual approach increases of mathematical representations ability increases in students with high initial category, medium, and low compared to conventional approaches.

Abstract

ABSTRACTThis research aims to demonstrate that the results of the statistical learning by applying cooperative learning model NHT better than TPS in class X SMK. This research was quasi experimental. The populationof the research was all students of class X semester II. Sampling was done by simple random sampling by taking two classes of sixth grade were randomly ie class X TKR-1 as the experimental class A and class X TKR-3 as the experimental class B, where the experimental class A implement cooperative learning model NHT and class experiment and implement cooperative learning model TPS. Calculation results obtained tcalculate = 3.32447 and ttable= 1.67078 so tcalculate>ttablethe real level of 0.05, the hypothesis was accepted. Thus we concluded that the results of a statistical study between cooperative learning model NHT better than TPS in class X.Keyword: the result of the study, nht, tps

Abstract

Penelitian ini bertujuan  untuk mengetahui apakah penerapan strategi pembelajaran Instant Assessment dapat meningkatkan keaktifan belajar matematika siswa dan untuk mengetahui apakah penerapan strategi pembelajaran Instant Assessment dapat meningkatkan hasil belajar matematika siswa. Subjek penelitian ini adalah siswa-siswa kelas VII-3 di SMP Al Maksum Percut Sei Tuan T.P 2014/2015 yang berjumlah 36 orang. Instrumen penelitian yang digunakan adalah tes dan observasi. Hasilnya meningkat pada hasil belajar dan rata-rata keaktifan siswa. Pada siklus I hasil belajar siswa yaitu 44,44% pada siklus ini yang menjadi tujuan dalam penelitian belum tercapai, dan observasi nilai rata-rata keaktifan siswa hanya 2,46. Siklus II Hasil belajar yaitu 75,00% dan nilai rata-rata keaktifan siswa 2,8. Siklus III mencapai ketuntasan hasil belajar siswa 91,67% dan ternyata pada siklus III ini menunjukkan peningkatan dengan rata-rata keaktifan siswa 3,06 dengan kategori baik.This research had purpose for know what the threatment of strategy learning Instant Assessment can increase  the student activity for subject math and for knowing  what the threatment learning instant assessment can increasing the result in subject math. The subjects of this research was the student of  VII-3 in SMP Al Maksum Percut Sei Tuan T.P 2014/2015 the sum of student was 36 people. The instrument of this research used the was test and observation. The resultwas could increase in student  outcomes and average of students’ activity. In the circle I the result of student abilitywas 44.44% in this circle become the purpose were not get student achievement and the average of more observation was 2.46. In the circle II the results of student ability was 75.00% and the average mask of observation was 2.8. in the Circle III the result of students ability was 91.67% and as we know the in  the circle III to school the increasing of average student achievement of 3.06 it show that student achievement in good category.

Abstract

ABSTRAKSalah satu kegiatan awal dalam meningkatkan pembelajaran adalah merancang perangkat pembelajaran yang mengacu pada suatu model agar memudahkan belajar. Perancangan pembelajaran dapat dijadikan titik awal upaya perbaikan kualitas pembelajaran. Ini berarti bahwa perbaikan kualitas pembelajaran haruslah diawali dari perbaikan kualitas desain pembelajaran, dan merancang pembelajaran dengan pendekatan sistem. Hendaknya dalam pembuatannya dipadupadankan dengan metode dan juga model yang sesuai dengan kebutuhan peserta didik agar pembelajaran lebih bermakna (meaning full). Penelitian ini adalah penelitian eksperimen yang dilakukan pada mahasiswa program studi pendidikan dengan tujuan: (1)mengetahui perbedaan kemampuan penalaran dan komunikasi matematis mahasiswa yang diajar dengan menggunakan LKM dalam model discovery learning dan metode ceramah; (2) menelaah proses jawaban mahasisa yang diajar dengan menggunakan LKM dalam model discovery learningdan metode ceramah; (3) menghasilkan perangkat pembelajaran matematika berupa LKM berbasis discovery learning yang layak digunakan untuk meningkatkan kemampuan penalaran dan komunikasi matematis mahasiswa matematika.Kata kunci: Discovery Learning, Metode Ceramah, LKM

Abstract

Penelitian ini bertujuan untuk menunjukkan bahwa hasil belajar statistika  dengan menerapkan model pembelajaran kooperatif tipe NHT (Number Head Together) lebih baik daripada TPS (Think Pair Share) pada siswa kelas X SMK. Jenis penelitian ini adalah eksperimen semu yang populasinya adalah seluruh siswa kelas X Semester II. Pengambilan sampel dilakukan dengan cara simple random sampling dengan mengambil 2 kelas dari 6 kelas secara acak yaitu kelas X TKR-1 sebagai kelas eksperimen A dan kelas X TKR-3 sebagai kelas eksperimen B, dimana kelas eksperimen A menerapkan model pembelajaran kooperatif tipe NHT dan kelas eksperimen B menerapkan model pembelajaran kooperatif tipe TPS. Hasil Perhitungan diperoleh thitung = 3,32447 dan ttabel = 1,67078sehingga thitung > ttabel pada taraf nyata 0,05 maka hipotesis diterima.Dengan demikian  diperoleh kesimpulan bahwa hasil belajar statistika antara model pembelajaran kooperatif tipe NHT lebih baik daripada TPS pada siswa kelas X This research aims to demonstrate that the results of the statistical learning by applying cooperative learning model NHT better than TPS in class X SMK.
