1. Reasonable use of multimedia technology according to the characteristics of the course

In the past, these characteristics of the electronic whiteboard course were only under the conditions of traditional multimedia teaching. It is really difficult for students to understand the mystery of the teacher with the three-inch tongue and the writing and drawing on the blackboard. Even if the laboratory is used to conduct some confirmatory subject experiments on related theories, it is difficult to solve some doubts in the students' minds. However, the use of electronic whiteboard multimedia teaching technology can indeed solve the specificity, invisibility and abstraction of this teaching course.

2. Fully use multimedia technology to improve classroom teaching efficiency

Under the previous teaching conditions, teachers use these flip-charts to explain these circuit diagrams, but the flip-charts are generally less negative and the lines are thinner, and the students seem to be struggling; or rely on the teacher to draw on the blackboard, which takes time and effort, and will also cause a classroom atmosphere Lonely, teaching efficiency is low. However, using multimedia teaching technology, the electronic whiteboard prepares these circuit diagrams in advance for the electronic whiteboard courseware, which not only saves time and effort when used, but also the image is clear and beautiful, which is easy for students to watch and easy for teachers to explain, and the teaching efficiency is significantly improved.

3. Proper use of multimedia technology based on students' actual situation

Students are the subject of teaching. The purpose of using all teaching methods is to learn from students. This is both our starting point and our goal. Therefore, in order to improve the quality of teaching, only by fully considering the students' cognitive abilities and cognitive laws can good teaching results be obtained.

The use of electronic whiteboard teaching has become a mainstream educational device, so that the classroom teaching process is memorized and reproduced. When the normal teaching session is completed, in order to emphasize the key points, or to allow the poor students to have a process of revisiting knowledge and consolidating knowledge, they can return to the required page to reproduce the teaching process, strengthen it, and help the poor students to carry out the second Study.

The emergence of the electronic whiteboard integrates traditional teaching and current information technology, while inheriting the traditional classroom teaching habits for hundreds of years, it meets the needs of the development of the times and makes up for the shortcomings of traditional multimedia courseware "more than preset, insufficient generation" . When teachers use the electronic whiteboard to prepare lessons, they only need to put the preset questions and materials in the resource library, and call them at any time according to the learning situation of the students during the class, which is more flexible and convenient. Thus realizing the multimedia teaching of electronic whiteboard in the true sense. In the usual teaching practice, give full play to the function of electronic whiteboard, make the classroom more abundant and fulfilling, and indeed improve the quality of teaching and improve the efficiency of teaching.
