Offline Teaching Method in Blended Teaching mode of Improving the Innovation Ability of Students in IT Majors

At present, all kinds of innovative applications of artificial intelligence, big data and other technologies in various industries and fields make the demands for the cultivation of innovative ability of IT talents more urgent. Aiming at the problem of insufficient cultivation of students' innovative ability in the existing blended teaching mode, this paper puts forward a theoretical teaching method based on four-stage and problem-oriented in the offline class, and a practical teaching method based on "entrepreneurial thinking". In the former teaching method, by dividing the explanation of a concrete theoretical knowledge into four stages: "concept", "problem", "application" and "innovation", and at the same time, designing some progressive problems in each stage to guide students to deepen their knowledge understanding and inspire their innovative thinking around the application and innovation of knowledge, and an example has been given to well illustrate the method. Meanwhile, in the latter teaching method, this paper also presents a practical teaching method based on "entrepreneurial thinking" to optimize the practical teaching links of the courses in IT major, in which the project-based teaching method and entrepreneurial thinking are adopted, and the practical process is divided into several stages as "demand analysis and topic selection", "scheme design", "scheme implementation" and "application and promotion", At each stage, some concrete guiding measures and examination and evaluation methods have been designed to effectively stimulate students' innovative thinking and innovative ability specific. Through the application of the above methods to the teaching practices in the "computer network" course, it is proved that this method plays a promoting role in the development of students' innovation and practical abilities.
