ANALYSIS OF MULTIPLE REPRESENTATION ABILITY AND THE RELATIONSHIP WITH THE CONCEPTUAL UNDERSTANDING OF PHYSICS

Penelitian ini bertujuan untuk menganalisis profil kemampuan multi representasi siswa SMA pada materi gerak lurus yang diukur menggunakan instrumen berbasis multi representasi, dan mendeskripsikan hubungan antara kemampuan multi representasi dengan pemahaman konsep siswa pada materi gerak lurus. Penelitian ini dilakukan pada siswa kelas XI IPA sebanyak 22 siswa di SMA Negeri 1 Sambit pada semester genap tahun pelajaran 2020/2021. Penelitian dilakukan dengan dua tahap yaitu pengembangan instrumen tes berbentuk esai dan pengukuran kemampuan multi representasi dan pemahaman konsep siswa. Uji validitas dilakukan untuk menguji kelayakan instrumen dan uji korelasi digunakan untuk menentukan hubungan antara kemampuan multi representasi dan pemahaman konsep siswa yang didasarkan pada data jumlah skor multi representasi dan pemahaman konsep. Hasil penelitian menunjukkan bahwa: 1) instrumen yang dikembangkan dinyatakan valid dari aspek konten dan bahasa dengan indeks Aiken sebesar 0.76 dan berdasarkan aspek konstruk dinyatakan sangat valid dengan indeks Aiken mencapai 0.86; 2). Kemampuan multi representasi siswa pada representasi verbal sebesar 43%, representasi matematik-simbolik 32% dan 25% untuk representasi gambar-simbolik. Kemampuan representasi matematik-simbolik dan verbal dikategorikan dalam kategori kurang dan kemampuan representasi gambar-simbolik siswa dikategorikan sangat kurang; 3) Rata-rata pemahaman konsep siswa pada materi gerak lurus sebesar 26%; 4)Berdasarkan uji korelasi diperoleh koefisien korelasi sebesar 0.726 yang menunjukkan bahwa kemampuan multi representasi dengan pemahaman konsep memiliki hubungan positif dan signifikan dimana jika kemampuan multi representasi siswa tinggi maka  pemahaman konsep siswa juga tinggi.

This study aims to analyze the profile of high school students' multi-representation ability on translation motion material measured using multi-representation based instruments and to describe the relationship between multi-representation abilities and students' conceptual understanding of translation motion material. This research was conducted on 22 students of class XI IPA at SMA N 1 Sambit in the even semester of the 2020/2021 school year. The research was conducted in two steps, namely the development of an essay instrument and the measurement of students' multi-representation abilities and conceptual understanding. The validity test was conducted to test the appropriateness of the instrument and the test used to determine the relationship between multi-representation abilities and students' conceptual understanding based on the data on the number of multi-representation scores and conceptual understanding. The results showed that: 1) the instrument developed was declared valid in terms of content and language with an Aiken index of 0.76 and based on the construct aspect declared very valid with an Aiken index of 0.86; 2) The multi-representation ability of students in verbal representation is 43%, the mathematical-symbolic representation is 32% and 25% is for image-symbolic representations. Representation ability in mathematic-symbolic and verbal were categorized in poor category and representation ability in image-symbolic representation were categorized in very poor category; 3) The average understanding of the concept of students on translation motion material is 26%; 4) Based on the correlation test, the coefficient is 0.726 which shows that the ability of multi-representation with concept understanding has a positive and significant relationship, if students’ multy representation ability is high, so students' understanding of concepts is also high.
