With the rapid development of network technology, English teaching has also been reformed, and the teaching mode has also undergone corresponding changes and improvements. The combination of computer and teaching mode has led to the emergence of a new teaching model to change the limitations of teaching mode. Therefore, this paper proposes a task-based teaching mode and analyzes the innovative teaching mode. Firstly, computer technology is used to analyze the teaching mode, and the indicators are divided according to the requirements of the teaching mode to reduce the interference factors in the teaching mode. Then, the computer technology analyzes the results of the university English teaching mode, forms the teaching model plan, and conducts the results of the teaching mode Comprehensive analysis. MATLAB simulation shows that under the condition of certain evaluation standards, the task-based teaching mode is effective in improving the comprehensive English ability of college students. The teaching efficiency is better than the traditional teaching mode.
