Abstract
This research aimed to produce astronomy learning media in the form of an annual solar apparent motion model. The students have difficulty in understanding the concept of celestial coordinate system. The media is needed to assist the students to understand the concept. The model is made of acrylic material and consist of horizon planes, sky pole track, equatorial track, sky meridians and solar track. The model is used to explain the position of the sun when its declination value is known at a particular latitude. Based on the assessment by 2 lecturers of content and media experts, the model has excellent category and reliable to be used. Based on small and large scale test, the model obtained good response and student express agree to the model when used in astronomy study. Thus, the model deserve to be used in astronomy learning, especially the concept of celestial coordinate system.
