Digitalization empowers teachers' teaching ability, teaching material content and teaching method reform.
First of all, digital empowerment improves teachers' teaching ability. In the "Three Education" reform, teachers are the leading factor in classroom teaching. To promote teacher reform, teachers' professional development is the foundation, teaching innovation is the starting point and team innovation is the core. First of all, teachers should actively participate in various activities and trainings to improve the ability of modern educational technology, and it is imperative to deeply understand the call of the intelligent age and the reform of teaching informatization. Secondly, teachers should actively declare the subject of educational reform through project research. For example, with the help of the online and offline mixed teaching reform project, they can list the knowledge points of the course, divide the work among the teaching team members, prepare lessons and grind lessons collectively, improve and improve the PPT of each knowledge point, and then shoot each knowledge point into an 8- 10 minute teaching video, upload it to the online teaching platform, and implement online and offline mixed teaching. Secondly, actively participate in educational and teaching ability competitions, coach students to participate in various competitions, and improve digital teaching ability.
The second is the content innovation of digital empowerment teaching materials. In order to meet the close connection between mobile classroom and teaching materials, a Rubik's cube book can be written, that is, two-dimensional codes are affixed to the knowledge points of teaching materials and after-school exercises, and students can watch teaching videos and detailed explanations of topics at any time by scanning the codes. For example, 99 QR codes are embedded in the textbook of Applied Advanced Mathematics (Volume I) edited by the author, which provides 68 teaching videos and 3 1 detailed exercises. The contents of Exercise Book of Applied Advanced Mathematics (Volume I) are arranged from shallow to deep, with detailed QR codes next to difficult topics and short answers at the end of the book. On the basis of paying attention to the theoretical knowledge of one-dimensional function calculus, the textbook adds professional MATLAB computer operation skills and application cases, such as instantaneous speed, tangent slope, optimization, volume of rotating body, plane graphic area, bank compound interest and so on. At the same time, the ideological, political and cultural contents of the course are increased, such as mathematical thoughts, stories of mathematicians, history of mathematics, and celebrities talking about mathematics. The content of teaching materials is closely related to industry posts, which is basic and practical. Combined with curriculum culture and curriculum ideology and politics, it makes up for the difficulty of cultivating students' practical ability and the general lack of humanistic quality education.
The third is the reform and innovation of digital empowerment teaching methods. The reform of teaching methods ultimately depends on the generation of students' learning methods. Without the continuous generation of learning methods, the classroom will not present a complex and colorful ecological style. Take the online and offline mixed teaching implemented by the author as an example. First, build online courses on the platform, upload teaching videos and teaching resources, and then teach according to the online class break time of 1 1 Students take part in online classes and finish videos, homework and discussions arranged by teachers in advance. Teachers use the end time of online classes to test students' learning effects, deepen learning content and guide students to discuss the application of practical knowledge and humanistic quality education in groups. At present, online resources are very rich, including 95 teaching videos with a total duration of 978 minutes, 196 1 homework, 1804 exam questions and 480 non-video resources.
At the same time, in the form of the integration of Internet technology and information-based courses, we have built three platforms for students, namely, learning platform+communication platform+competition platform, to guide students to cooperate in learning, which not only improves students' interest in learning and practice teaching projects, but also strengthens students' ability to apply mathematics and quality education cases, and also cultivates students' professional ability and personality quality with the help of curriculum ideology and politics, realizing the two-way integration of "practical ability+humanistic quality". Digital empowerment teaching method not only benefits students in a single class, but also benefits students in the whole school and the whole network. During the epidemic period, our online courses provided high-quality curriculum resources for many higher vocational colleges to implement the requirements of "no class, no class and no study" of the Ministry of Education. At present, the cumulative number of elective courses has reached 16788, benefiting teachers and students in more than 230 colleges and universities.
Countermeasures
Improve the quality of teachers, optimize the content of teaching materials and choose appropriate teaching methods.
The reform of "three religions" is a whole, and the three are linked. Therefore, the reconstruction of teaching organization is the premise of implementing the "Three Education" reform, in which improving teachers' quality is the key, optimizing teaching materials is the core, choosing appropriate teaching methods is the foundation, and the digital empowerment of "Three Education" is an effective means of modern higher vocational education reform.
The first is to "empower" teachers and vigorously improve the information-based teaching ability of teachers in higher vocational colleges. It is the development direction of higher vocational education in the future that teachers combine professional knowledge and information means perfectly in the teaching process, so as to improve teaching effect and complete teaching tasks efficiently. However, at present, there are still some problems in higher vocational colleges, such as the weak theoretical basis of teachers' informatization teaching and the need to strengthen the ability of curriculum design of informatization teaching. Therefore, the improvement of teachers' teaching ability is an important starting point for the reform of "three educations". As a group of teachers who serve the high-quality development of vocational education in the new era, improving teachers' ability to use information-based teaching methods to assist teaching and flexibly use new media technologies is not only a powerful boost to realize the talent training program, but also a crucial basic work.
The second is to "empower" teaching materials and speed up the preparation of three-dimensional new teaching materials. Textbooks are the support and foundation of teaching content and an important carrier for implementing curriculum reform. Accelerating the reform and innovation of teaching materials is an important measure to update teaching content, promote teaching reform and improve the quality of personnel training. At present, vocational colleges still lack "three-dimensional" teaching materials suitable for online and offline use. Therefore, the fundamental measure to promote the reform and innovation of teaching materials is to promote curriculum construction, which is oriented and carried out in the logical order of updating teaching content, improving curriculum standards and compiling or developing teaching materials. At the same time, in practice, we should combine the construction of teaching materials with teaching reform and encourage the compilation of new teaching materials.
The third is "empowerment" teaching, and vigorously promote the reform of online and offline mixed teaching mode. The core of teaching method reform is the reform of classroom teaching mode. In order to cultivate high-quality technical and skilled talents that meet the needs of industries and enterprises, and to effectively link the teaching process with the working process in vocational colleges, we must reform the traditional classroom teaching mode, boldly carry out the reform of online and offline mixed teaching mode, and give full play to students' dominant position. First of all, the learning content is modularized, and the curriculum model is diversified, so as to establish classroom teaching content and model suitable for different professional groups. Secondly, the teaching method of the course is "intelligent", and the "three classes" teaching mode of online class and computer software training class is implemented. Among them, the basic theory is taught in the offline class, the group cooperates and discusses, and the teacher answers questions; Teaching basic knowledge and skills in online classes to promote extended learning; Computer software training courses complete comprehensive skills training, improve practical ability, and serve professional learning and mathematical modeling competitions. At the same time, by upgrading the online classroom and building a smart learning platform, the "three classrooms" can be connected in real time, resources can be shared and promoted each other, and a learner-centered classroom teaching mode of vocational education with deep interaction between teachers and students can be established.
