The findings indicate differences in mastery and application of concepts among students using web-based learning but no disparities based on different learning styles. In conclusion personalized web-based learning leads to variations in mastery and application of concepts compared to non-personalized methods with no discernible discrepancy in the mastery and application of concepts between students with different learning styles. Research indicates that personalized web-based learning is more effective in enhancing mastery and application of concepts compared to non-personalized methods. By customizing web-based learning to individual learning styles students can enhance the quality and outcomes of their learning.
