Differences analysis understanding the concept of students between the three islands (Java, Kalimantan, Papua) through multiple representations approaches to the material of Time Dilation

The success of students in the achievement of learning if students have a concept of understanding and able to represent the concept it understands through various representation. This study aims to analyzing differences in understanding the concept of students between the three islands (Java, Kalimantan, Papua) through multiple representation approach on Time Dilation Material. Dilatation of time enters into part of the discussion of special relativity theories that require High Order Thinking and complex Abstraction reasoning in understanding the concept. This research method is Quantitative with Comparative Hypothesis. The sample of this research is Physics Education students in Java, Kalimantan, and Papua. Sampling technique is Purposive Sampling. This research instrument is in the form of a description test that is completed in the form of Verbal (V), Diagram (D), Graph (G), and Mathematical (M) representations. Data processing is done by linking three aspects of conceptual understanding and four forms of representation in three different study samples. The results of this study indicate significant differences that occur in several variable opportunities with different scopes of research areas. This research is expected to be studied more deeply and sustainably.
