Abstract

Tujuan penelitian ini untuk mengetahui: (1) Tingkat pemahaman konsep operasi bentuk aljabar, (2) Hasil belajar matematika, (3) Hubungannya antara pemahaman konsep operasi bentuk aljabar dengan hasil belajar matematika. Penelitian ini menggunakan pendekatan deskripsi korelasi. Populasi berjumlah 360 siswa/I besar sampel dihitung dengan rumusan solvin. Intrumen pengumpulan data angket. Dalam penelitian ini juga diperoleh koefisien korelasi rxy = 0,974, sedangkan t hitung = 37,48. Nilai t tabel (dk 76 : α = 0,05) adalah sebesar 1,995 sehingga diperoleh t hitung = 37,48 > t tabel = 1,995. Sedangkan koefisien determinan I = 0,94 atau 94% yang berarti besarnya sumbangan variabel bebas X terhadap variabel terikat Y adalah 94 % sedangkan 6% lagi ditentukan oleh faktor lain. Hasil penelitian menunjukkan ada hubungan antara pemahaman konsep bentuk aljabar dengan hasil belajar matematika siswa kelas VII MTsN 2 Medan.

Abstract

The purpose of this study is to determine: (1) How does an understanding of the concept of operations in the algebra class VII MTsN 2 Field, (2) how mathematics learning outcomes of students in class VII MTsN 2 Field, (3 ) How is the relationship between the understanding of the concept of operations with the algebra mathematics learning outcomes of students in class VII MTsN 2 Field. This research is a quantitative method decryption. The population in this study were student / I class VII MTsN 2 Field. The population in this research were 360 students / class VII I MTsN 2 Field, while the sample in this study taking 20% of the total student population that is 78 people. Instruments of data collection in this research is a test. Based on these results, obtained both variables were normally distributed research. For an understanding of the concept of form algebraic variables (X) obtained x2hitung = -252.11 and students' mathematics learning outcome variable (Y) obtained x2hitung = -13625.02, while x2tabel the significant level α = 5% is equal to 11.070. So for both variables were obtained count x2 > x2 table and this means that the two variables are normally distributed research. In this study correlation coefficient rxy = 0.974, t = 37.48 while. T value table (dk 76: α = 0.05) is equal to 1.995 to obtain t = 37.48> t table = 1.995. While the coefficient determinant of I = 0.94 or 94%, which means the amount of the contribution of independent variables to the dependent variable Y X is 94%, while 6% are determined by other factors. So the conclusions of this research are: there is a relationship between the understanding of the concept of the algebra of the learning outcomes math class VII MTsN 2 Medan.
