In order to improve the effectiveness and learning performance of English learning among college students, this study investigates the impact of MOOC and online live teaching on their English learning performance. Firstly, the limitations of traditional English learning models in universities were analysed. Secondly, based on the characteristics of MOOC and online live teaching, it is analysed that MOOC and online live teaching have the advantages of diverse learning resources, enhanced learning interactivity and participation, personalised teaching, flexibility and convenience. Finally, the impact of MOOC and online live teaching on the English learning performance of college students is elaborated from four aspects: improving learning effectiveness and motivation, meeting diverse needs of students, improving learning efficiency, and cultivating self-learning ability. The example analysis results show that the attendance rate, classroom participation, and English learning performance of the experimental group are higher than those of the control group.
