Purpose: It is used for judging the advantages and disadvantages of information technology foundation course teaching in health vocational colleges. Method: In teaching, it takes the two classes of 2012 grade nursing major as the experiment object. The comparison class adopts traditonal and speaking-practice combination teaching method and the experiment class adopts task-driving teaching method. When the semester finishes, it conducts testing andd questionnaire survey, collecting the relevant data, analyzing the changes of students in the aspects of performance, learning interest and attitude, autonomous learning consciousness and ability after experiment class adopting new teaching methods. Result: The exam performance of experiment class is obviously higher than the comparison class, and the experiment class has an obvious improvement in the aspects of learning interest, autonomous learning consciousness and ability, and the difference has statistical significance. Conclusion: The task driving teaching method is suitable for the status of information foundation teaching in health vocational colleges, which improves students' performance significantly and is good for students' learning interest and enthusiasm, obtaining good classroom effect. Also, it makes students' autonomous learning consciousness and ability improve greatly. 展开更多
