본 연구에서는 고등학교 과학과 진로선택과목 중 하나인 과학사 과목에 대한 학생들의 선택률이 낮은 문제 상황을 개선하기 위해 과학사 과목의 한국의 전통 과학 단원에서 다루는 전통 천문의기 9종과 관련한 학습 요소 및 성취기준을 분석하여 내용의 적합성과 위계성을 분석하였다. 이러한 분석 결과를 토대로 학년군을 달리한 과학과 교육과정에서 각각의 천문의기를 교수·학습에 활용할 수 있는 방안을 제안하였다. 본 연구의 결과를 출발점으로 하여, 전통 천문의기와 관련된 구체적인 성취기준 또는 탐구 활동을 개발하는 후속 연구가 이루어질 수 있다면 한국의 전통 과학문화에 대한 학생들의 인식을 제고할 수 있고, 더 나아가서 과학사 과목에 대한 학생들의 선택률을 높일 수 있을 것으로 기대된다.

Song I-Yeong (1619 ~ 1692), who was an astronomy professor of Gwansanggam (觀象監, Bureau of Astronomy), created the Honcheonsigye (渾天時計, Armillary Clock) in 1669 (10th year of King Hyeonjong Era). Honcheonsigye was a unique astronomical clock which combined an armillary sphere, the traditional astronomical instrument of the Far East, with the power mechanism of western alarm clock. The clock part of this armillary clock is composed of two major parts which are the going-train, power unit used the weight, and the time signal system in a wooden case. The time signal system is composed of four parts which are the time-annunciator, the striking train, the 12 different time-announcing medallions and the sound bell. This clock has been neglected for many years and its several components have been lost. This study is to understand the structure of time signal system and suggests the restoration process.

During King Sejong's reign in early Chosen Dynasty, the Korean science had been in full bloom. Among the many splendid achievements of the period, though most of them are not extant, astronomical instruments and clocks made for equipping the Royal Observatory are taken as typical works that reflect the characteristics of the King's scientific projects and discussed in the view point that what and how much a well-planned drive and a future-oriented leader can accomplish.

The purpose of this study was to explain how extraordinary the scientific technology or our ancestor was from the modern perspective by remodeling the most unique astronomical instrument, So-ganui (小簡儀), developed in the Sejong Period (世宗時代) after being examined with contemporary and the principles of the science and observational technology would be properly understood and measured directly. When measuring the altitude of the sun and azimuth using So-ganui, it was adjusted with the horizontal coordinate system and measured using Jipyeonghwan (地平環), Ipeunhwan (立運環) and Guyhyeong (窺衡). Based such measuring principles, the measurement accuracy proposed using So-ganui are as follows. The remodeled So-ganui produced approximately ${\pm}0.29$ degrees error on average at high altitude while in measuring the azimuth degrees, there was difference of ${\pm}0.35$ degrees. Since the theoretically, the measurement error for So-ganui was ${\pm}0.5$ degrees, the remodeled So-ganui could accurately measure at the high altitude compared to So-ganui from the Sejong period. In the study, So-ganui, which has disappeared, has been remodeled in modern perspective to be used as the educational material to accurately understand the principles of science and measurement technology from the Sejong period. The findings could contribute to raising the reputation in the astronomical observations from the documents from the Sejong period. Furthermore, this study has materialized the celestial and sky our ancestors have viewed with the observational principles of their times, on the computer screen via a webcam, bringing out interest in the traditional science for the students.

Honsangui (celestial globe) which is a water-hammering method astronomical clock is recorded in "Juhaesuyong" which is Volume VI of supplement from "Damheonseo", written by Hong Dae-Yong (1731~1783). We made out the conceptual design of Hong Dae-Yong's Honsangui through the study on its structure and working mechanism. Honsangui consist of three rings and two layers, the structure of rings which correspond to outer layer is similar to his own Tongcheonui (armillary sphere) which is a kind of armillary sphere. Honsang sphere which correspond to inner layer depicts constellations and milky way and two beads hang on it as Sun and Moon respectively for realize the celestial motion. Tongcheonui is operated by the pendulum power but Honsangui is operated by water-hammering method mechanism. This Honsangui's working mechanism is the traditional way of Joseon and it was simplified the working mechanism of Shui y$\ddot{u}$n i hsiang t'ai which is a representative astronomical clock of China. This record of Honsangui is the only historical record about the water-hammering method working mechanism of Joseon Era and it provide the study of water-hammering method mechanism with a vital clue.
