Abstrak (Berisi Bastraknya saja, Judul dan Nama Tidak Boleh di Masukan)
Berdasarkan pengalaman praktik lapangan di Sekolah Menengah Pertama (SMP), masih banyak siswa yang menganggap fisika merupakan mata pelajaran yang sulit karena banyak menggunakan rumus matematis dan banyak pengembangan konsepnya. Hal ini dikarenakan kemampuan mereka dalam mengoperasikan rumus fisika secara matematika masih kurang. Apalagi pada materi gerak, siswa harus bisa mengoperasikan rumus matematika, sebab terdapat beberapa hubungan dan formulasi matematika dalam penguasaan konsep gerak. Salah satu upaya yang dapat membantu siswa dalam meningkatkan penguasaan konsep khususnya pada materi gerak adalah menumbuhkan skill representasi matematika mereka. Berdasarkan hal tersebut, peneliti mencoba melakukan penelitian untuk mengetahui pengaruh skill representasi matematika terhadap penguasaan konsep gerak siswa SMP. Penelitian ini bertujuan untuk: (1)Mendeskripsikan pengaruh skill representasi matematika terhadap penguasaan konsep gerak siswa SMP, dan (2)Mengetahui peningkatan penguasaan konsep gerak siswa SMP dengan menggunakan skill representasi matematika. Penelitian ini dilakukan di SMP Negeri 1 Pringsewu, menggunakan satu kelas yaitu kelas VII5 dengan jumlah sampel 38 siswa dan menggunakan desain One- Group Pretest – Posttest. Pada penelitian ini diperoleh data skill representasi matematika, data pretest dan posttest penguasaan konsep siswa yang berdistribusi normal dan linier. Kemudian untuk menguji pengaruh dilakukan uji linearitas, korelasi, dan regresi linear sederhana antara data skill representasi matematika dan data posttest penguasaan konsep. Sedangkan untuk mengetahui peningkatan penguasaan konsep dilakukan perhitungan persentase kenaikan skor, N-gain, dan uji paired samples t test dari data pretest dan posttest penguasaan konsep siswa. Hasil penelitian ini menunjukkan bahwa: (1)Terdapat pengaruh linear yang positif dan signifikan antara skill representasi matematika terhadap penguasaan konsep gerak siswa SMP dengan kontribusi sebesar 67% dan persamaan regresinya adalah Y’ = 7,818 + 1,288 X, dan (2)Terjadi peningkatan yang signifikan dari penguasaan konsep gerak siswa SMP dengan menggunakan skill representasi matematika, dengan nilai N-gain rata-rata 0,58 yang termasuk dalam kategori sedang. Based on practical experience in the field of secondary school (junior high school), there are still many students who think physics is a subject that is difficult because many uses mathematical formulas and a lot of concept development. This is due to their ability to operate in mathematical physics formula is still lacking. Moreover, the motion of matter, students should be able to operate a mathematical formula, because there are some relationships and mathematical formulations in the mastery of the concept of motion. One effort that can assist students in improving mastery of concepts, especially on the motion of matter is to develop representations of their mathematical skills. Based on this, researchers are trying to do research to determine the effect of the representation of mathematical skills to junior high school students' mastery of the concept of motion. This study aimed to: (1) Knowing the mathematical representation of the influence of skill on students' mastery of the concept of junior high school movement, and (2) Determine the increase mastery of the concept of motion junior high school students using mathematical representation skills. The research was conducted in SMP Negeri 1 Pringsewu, using a single class ie class VII a sample of 38 students and design using the One-Group Pretest - posttest. In this study obtained data representation of mathematical skills, pretest and posttest data students' mastery of the concept of a normal distribution and linear. Then to test the influence of tested linearity, correlation, and simple linear regression between the data representation of mathematical skill and concept mastery posttest data. As for knowing increasing mastery of the concept of percentage increase in score calculation, the N-gain, and the test of paired samples t test of pretest and posttest data student mastery of concepts. The results of this study indicate that: (1) There is a positive linear influence and significant relationship between the representation of mathematical skills to junior high students 'mastery of the concept of motion with a contribution of 67% and the regression equation is Y' = 7,818 + 1,288 X, and (2) Occurs significant improvement of students' mastery of the concept of motion SMP by using mathematical representation skills, with the value of N-gain an average of 0,58 is included in the category of being.
