PENGARUH PENGUASAAN VEKTOR TERHADAP HASIL BALAJAR FISIKA SISWA PADA MATERI HUKUM II NEWTON TENTANG GERAK KELAS X SMA NEGERI PADANG BOLAK JULU

Abstract

The aim of this research was to know whether there was a significant influence between
vector mastery on students’ achievementc in Newton’s law II about motion subject at
tenth grade students of SMA Negeri 1 Padang Bolak Julu. The approach of this research
was quantitave by applying descriptive and correlation method. The population of this
research was all the tenth grade students of SMA Negeri 1 Padang Bolak Julu which
include 10 classes or 210 students. By applying random sampling technique, based Taro
Yamena formulate, the writer took the sample 68 students. In collecting the data, the
writer used test. The writer used two ways to calculate the data. They are descriptive
analysis and inferential analysis. Based on the data analysis, it could be gotten that the
average of vector mastery was 69.22 and it was catagorized ”good”. While mean of
students’ achievement in Newton’s law II was 66.73 and it was catagorized ”good. Based
on statistics analysis calcution, it could be gotten that tcount = 16, in error level significant
5%, confidence level significant 95%, df = N – 2 = 68 -2 = 66, it could be gotten that ttable=
1.67. It could be seen that tcount was greater ttable (16 >1.67). The hypothesis was accepted. It
means that there was a significant influence between vector mastery on students’
achievement in Newton’ law II about motion subject at the tenth grade students of SMA
Negeri 1 Padang Bolak Julu.
