| Summary: | 碩士 === 國立臺灣師範大學 === 資訊教育學系 === 98 === Astronomical observation has been difficult to improve the teaching of the curriculum implementation, but also elementary school children was generally one of the most difficult element of learning (姜滿，1997).Astronomical observations rely on the experience of practice in order to combine the formation of self-concept of students, while the experience of the implementation but with the
current system of elementary education in conflict with each other.
The study concludes that a small astronomical observatory of teaching abroad Loss and difficulties to be solved from two major factors: teaching factors (internal factors) and environmental factors (external factors). To address these difficulties and thus the development of handheld digital armillary sphere (Mobile Digital Armillary Sphere), to break the current status of teaching modules on the
astronomical cycle.
Handheld Digital armillary sphere (MDAS), is the use of mobile devices based on the G-sensor and electronic compass sensors, mobile devices and calculate the angle between the holders of the field of view and distance, and then calculate the field of vision occurs Star , displayed in the screen of mobile devices, such mode of
operation also known as Augmented Reality (Augmented Reality).
Final results confirm, MDAS into teaching elementary astronomy course, can
enhance the learning interest of students and the best learning results.
