The aims of this study is to investigate and analyze how Kepler, Galilei, and Carnot, who were creative physicists, used abductive reasoning in formulating hypotheses for their theories0 establishment. Through review and analysis of related literature, the author found that Kepler had formulated his own hypothesis to build a new theory for eye vision by employing the optical phenomenon in a spherical lens, Galilei had formulated his hypothesis about free falling in a vacuum by employing a pendulum motion experiment and a thought experiment, and Carnot had formulated his hypothesis about the Carnot cycle and the efficiency of a heat engine by employing the principles at work in a hydraulic machine. All the results of their abductive reasoning, and their thinking process patterns can be used as effective models for teaching creativity to students and for learning science.

본 연구에서는 Kepler, Galilei, Carnot 등이 과학적 가설을 형성하는 과정에서 어떠한 귀추적 사고를 했는지 그 유형을 분석하였다. Kepler는 시각 이론을 형성할 때 구면 렌즈에서 일어나는 광학적 현상을 도입하여 가설을 형성하였으며, Galilei는 진공 중에서의 자유 낙하 운동 가설을 형성함에 있어 진자 운동을 관찰한 결과와 사고 실험을 도입하였으며, Carnot는 Carnot 열기관과 열기관의 열효율 가설을 형성하는 데 수력 기계의 원리와 수력기계에서의 효율을 도입하였다. 이들의 사고 과정 패턴은 학생들의 과학 창의성 지도에 효과적인 모형으로 활용될 수 있다.
