Development of �avatar� Learning Media Using Smart Apps Creator (Sac) to Improve Student Abstraction Ability

This research is motivated by the low ability of students' abstraction while abstraction ability is a very important ability possessed by students. Based on the results of observations and interviews with one of the mathematics teachers at SMPN 1 Jiwan, it was found that students were not able to apply appropriate concepts when working on mathematical problems. In addition, the learning process carried out at SMPN 1 Jiwan still uses conventional methods with the lecture method assisted by print media. This causes a lack of enthusiasm of students when participating in learning. This study aims to develop AVATAR learning media with the Auditory Intellectually Repetition learning model which includes videos, material, sample questions, and practice questions adapted to indicators of abstraction ability and presented interactively so as to improve students' abstraction abilities. This study uses the Research and Development (R&D) method using the 4D development model which consists of the defining stage, the design stage, the development stage, and the deployment stage. The results obtained from this study were that the AVATAR learning media was declared valid with a percentage of 85.00% and very practical with a percentage of 86.36% based on the student response questionnaire
