Abstract
The purpose of this research was to develop an innovative, practical learning module on the mass-luminosity and mass-lifetime relationships for main sequence stars in the Hertzprung-Russell (H-R) diagram, as well as to create a simple experimental tool and assess the effectiveness of the module. The study sample consisted of 50 B.Ed. Science students and a 10-item multiple-choice assessment were used as the research tool.
The findings revealed that the relationships for mass-luminosity and mass-lifetime for main sequence stars are expressed as follows: L=2.224M3.365 (R2=0.840) and t=4.498M-2.36 (R2=0.725), which align closely with theoretical predictions in astronomy. Additionally, the results indicated that the learning module significantly improved the participants’ knowledge. The average pre-test score was 3.78±0.1 (st.err), while the post-test was 9.88±0.1 (st.err). These results suggest that the practical learning module on the mass-luminosity and mass-lifetime relationships for main sequence stars effectively enhanced the target group’s understanding of the concepts
