Computer simulations have demonstrated the potential to facilitate this process by highlighting students' misconceptions and presenting plausible scientific conceptions. Thus, it is best to learn astronomy using simulations. Statistical results showed that the academic performance of the respondents improved when taught using the stellarium-based activity. The data pointed out that data analysis results shows that by conventional criteria, the differences of the scores on the different competencies is considered to be extremely statistically significant Results revealed that the stellarium-based activity is effective in teaching the cycles of the sky. The respondents of this study were composed of 28 students.

Cabahug FORUM for Literacy, School Year 2017-2018. This study focused on effectiveness of the stellarium-based activity on the academic performance of Grade 11 STEM Strand students of Sotero B. This study was carried out to understand and bring to fore if a simulation-based activity is effective on the academic performance of the students which has a general outlook to enhance meaningful science learning.
