고교진로연계형 우주역학 탐구 프로그램 개발 및 적용 : 우주탐사선 궤도 전이 시뮬레이션을 중심으로 = Development and Implementation of a Career-Connected Astrodynamics Inquiry Program for High School Students: A Focus on Orbital Transfer Simulation of Space Probes

다국어 초록 (Multilingual Abstract)

This study aimed to develop a career-linked astrodynamics inquiry program for high school students based on scientific inquiry processes and to examine its educational effects in fostering future space talent in the space age. To integrate the fragmented treatment of Kepler’s laws and Newtonian mechanics in the existing curriculum, a 16-session program centered on orbital transfer modeling of space probes was designed. The program was developed based on the ADDIE model and implemented using the 5E instructional model. It consisted of inquiry-based activities, including orbital motion exploration, numerical calculations using the Euler method, and Python-based simulation tasks.
The participants were 12 twelfth-grade high school students. To evaluate the effectiveness of the program, pre- and post-question generation tasks were administered, and paired-samples t-tests were conducted to analyze changes in creativity (fluency), scientific validity, and logical thinking. The results indicated statistically significant improvements in creativity, scientific validity, and logical thinking in both open-ended and closed-ended tasks (p < .01). In addition, students demonstrated a more intuitive understanding of orbital motion and orbital transfer concepts through simulation-based inquiry activities.
This study is educationally significant in that it integrated astrodynamics concepts with inquiry activities and Python-based simulations and implemented them as a career-linked interdisciplinary inquiry program applicable to the high school credit system.
