Mixed learning model integrates online and offline courses closely, breaks the time, space and object constraints while ensuring the quality of teaching, and puts forward new ideas for the teaching reform of Higher Vocational education. Taking the course of Microcontroller Programming as an example, on the basis of analyzing the existing mixed learning mode, relying on the network teaching platform, a mixed learning mode suitable for engineering courses in higher vocational colleges is constructed. With the development of modern education technology, network teaching occupies a unique advantage in social and educational sense, but there are some shortcomings in network teaching, such as emphasizing theory over practice, imperfect management system and difficult communication between teachers and students.
The traditional classroom teaching, though constrained by time and space, also has the advantages of ensuring the realization of theory to application, teachers timely grasp the students’learning level and so on. The complementary advantages of network teaching and traditional classroom teaching have become the focus of current scholars and experts, and the hybrid learning model has also come into people’s attention. Blended learning, as a new learning method or concept, closely integrates online and offline courses.
At present, many scholars at home and abroad have conducted in-depth research and Exploration on blended learning. The most typical representative, Singh, believes that blended learning is to adopt appropriate learning methods for the right people at the right time and to cooperate with different individual learning styles so as to enable them to master appropriate knowledge and skills so as to optimize their learning effects. 。 In China, many researchers have different definitions of blended learning, but most of them think that blended learning combines the advantages of traditional learning with online learning, which not only plays the role of teachers in guiding, inspiring and supervising the course construction and research based on blended learning, but also improves the initiative, enthusiasm and creativity of students.
Mixed learning also presents a variety of modes: K-12 education in the United States adopts the mixed learning mode of “conversion”, “flexibility” and “menu customization”; Liu Shenghua constructs the mixed learning mode of “course introduction (objectives and contents) – teaching activities – teaching evaluation” in the basic computer network course, and has achieved good results in practical teaching.
The Guo Cultural Revolution explored the mixed teaching mode of educational technology, including face-to-face teaching and network teaching, and established a special “network classroom” for the curriculum. There are many factors affecting the application of blended learning in College teaching, especially in Higher Vocational colleges, such as diverse sources of students, uneven basis of students and diversified teaching environment. These factors lead to higher requirements for blended learning mode.
The course “Microcontroller Programming Basis” is an important software design course for electronic information specialty. It has strong engineering practicality to implement C language project teaching with single chip computer as the carrier. The teaching object of this course is higher vocational students, enterprise technicians and training teachers.
The learning time of students is not fixed, the learning foundation is uneven, and the learning goals are different. This requires flexible arrangement of teaching activities according to actual needs. Traditional classroom is difficult to adjust.
The course also emphasizes that the application of theoretical knowledge to practice requires students to carry out a large number of practical activities, which is difficult to achieve in the network classroom. The combination of web-based learning and classroom learning not only breaks the limitations of learning objects, time and space, but also completes the task of transforming theory into practice.
There are five basic project areas in the course: introduction to C programming, compiling the first C program (C program structure, data type, operator and expression, etc.), input and output of students’grades (formatted input and output), design of key control circuit (selection structure programming), design of pattern colored lamp circuit (circular control).
Programming). Four areas of project learning include digital display circuit design (array application) and traffic light circuit design (function application). Class student achievement ranking (application of pointer), design of comprehensive management system of student achievement (application of preprocessing, structure and document) and study field of a comprehensive innovation project. Before class, according to the different teaching objects, the menu-based combination of learning items is included in the teaching plan, which opens the online classroom learning rights of the selected items for students.
Students complete the required learning tasks online, and instructors make relatively individualized network learning plans for students according to the completion of students, and guide students to reflect on learning problems and solve them. In face-to-face classroom, through the data of network feedback, we can solve the difficult and difficult problems, thermostatic element and arrange the training projects reasonably.
At the same time, students can also learn interesting courses and expand knowledge in groups, discuss in groups and discuss with experts in the expert library on curriculum issues, and ultimately complete the corresponding expansion tasks. The application of blended learning model in curriculum makes students move from teaching interactive course to learning-centered subject teaching, which makes students learn relative to professional skills.
While completing their learning tasks, they can also obtain greater satisfaction of their personal interests and bring a series of complete learning to students. Experience. In recent years, due to the influence of technology and teachers in Higher Vocational colleges, the mixed learning model has only been tried in a small range.
With the advocacy of “learning-centered” teaching concept, the introduction of mixed learning will also launch a series of argumentative thinking and resource-based construction.
