        abstract = {Development of Authentic-UG adopting augmented reality technology on the Android platform with ARCore SDK that can measure lines and measure angles with high accuracy is an advantage that can be used for learning geometry to students in authentic learning design. Authentic-UG can detailed record each student's learning activities with the xAPI technology, the system also implemented with annotation features to facilitate student for explaining the answers after searching for geometry objects. Authentic-UG has a flexible system with the use of the RESTFUL API protocol that can be connected to the Dashboard-UG system, so that teachers can see each student's process when doing authentic activities.
In this study, we developed the Authentic-UG to facilitate student in authentic learning and we investigate the relationship between learning behavior and learning assessment with learning achievement in fourth-grade elementary school students to learn geometry in the concept of angle and the concept of line. The participants of this study with 50 students, divided two groups that 25 students in the experimental group using Authentic- UG and 25 students in the control group for 10 weeks with the same initial prior knowledge between groups.
The statistical results after using Authentic-UG in the learning process indicate that the experimental group has a better learning achievement, especially in the skill of estimation ability on geometry objects. The results of authentic work also checking by teacher assessment and peer assessment using scaffolding. Therefore, the most influential learning activities to help estimation ability in the combine topic which combines the angle concept \& line concept and also the scaffolding can work well to help peer assessment quality. There is a phenomenon that students only focus on the concept of angle which is shown by the level on the accuracy of angle is more influent than the level of accuracy of the line. Student feel that using Authentic-UG is more happy learning experience because student feel motivated also healthy to active explore to searching geometry object and make measurement in the authentic environment.}
