However, because many teachers, especially older educators, are not used to this teaching equipment, there may be some difficulties in operation. Therefore, it is necessary to organize teacher training and use the electronic whiteboard collectively. In addition, teachers should also discuss, discuss and exchange their experience in using the electronic whiteboard. How to use such advanced equipment for our teaching and provide effective auxiliary function for teaching really needs continuous learning and exploration. Now, I would like to share some of my experiences in using the electronic whiteboard. I hope everyone can learn from each other and improve the application level of the electronic whiteboard. One of the most important performance characteristics of the electronic whiteboard is the interactivity of its electronic courseware. Therefore, we should change the production method of traditional PPT electronic courseware, comprehensively utilize all resources, including the teaching resource library supporting the electronic whiteboard software, as well as network resources, use PPT courseware with pictures and texts, and add necessary animation videos to enrich our teaching electronic courseware. In order to make the whiteboard serve our classroom teaching better, we need to design some courseware according to the class and help us break through some important and difficult points in teaching. How to make good use of electronic whiteboard software and how to make rich electronic courseware is the first step for us to use electronic whiteboard in teaching. Cleverly using the toolbar to expand the menu from the "Start" button, there are options such as shielding screen and spotlight, which are some special functions of the electronic whiteboard. Combining these functions with laser pens and highlighters can of course highlight the key points in the courseware more effectively and leave a deep impression on students. Magnifying glass cultivates students' observation quality. The teacher's physical demonstration can't make all the students realize the attention points of observation. It is especially suitable for teaching content that can't be displayed by the whole class, but needs to be seen by the whole class. I feel that it is especially suitable for various classifications in teaching. You can zoom, delete, clone and other operations on multiple objects by selecting multiple objects in turn, instead of doing similar operations on one object repeatedly at a time. Teachers can also write, draw, draw, circle, dot and other operations on it at will during the demonstration call, and they can also change the background picture and color, enlarge and reduce the picture at any time, and so on! Make good use of the Undo key. Many teachers will inevitably make no clerical errors in their comments or writing on the blackboard. I find that the more common practice is that teachers use erasure (area erasure or point erasure), so that we first click on the eraser, then click on the area erasure or point erasure, and then click on the pen we used before (hard pen, soft pen, highlighter pen and laser pen) to continue writing, which requires several procedures. With the Undo key, it may be faster. For the use of cleaning tools, it greatly saves the manpower to clean the blackboard, and can also be cleaned selectively at one time. Demonstrate clearing the annotation layer, clearing the object layer, etc. The smart pen that frequently writes electronic whiteboard with soft pen provides a simple and effective drawing function for the input of common geometric figures, which is of course a very good tool for the rigor of teaching. Our teacher often laments that students don't use rulers and compasses to draw pictures. As everyone knows, students are often influenced by teachers and draw pictures by hand. If the circle is not round, it should be straight. With the smart pen, it will naturally give students a correct orientation and make the blackboard writing more standardized, rigorous and beautiful! The electronic whiteboard comes with a pointer and soft pens of different colors. When you click on the whiteboard with the pointer, you should touch the whiteboard with the soft head vertically. To protect the whiteboard, we should get into the habit of writing with a soft pen. Annotation Scalable annotation is the most commonly used operation in whiteboard interaction. The new version of the software has different ways, such as transparent page annotation and screen page annotation. After transparent page annotation, only the annotation part roams, while screen page annotation can roam all the screen contents, leaving blank parts for writing. Annotation roaming is a method that teachers often take in dealing with the shortage of pages, but in my use, I found that we can take the method of reducing the screen, which on the one hand frees up the space for writing, on the other hand preserves the original content, so as to avoid the situation that students don't copy the questions in time and don't know what they are talking about and listen to the teacher singing a monologue. Lock the focus object. Take the literacy class as an example. If you drag a field from the public gallery and then you don't want to change it in the next operation, you can lock it. The method is to select the object to be locked, click the Edit menu button in the upper right corner, and select Lock in the pop-up menu. After locking, the focus box of the locked object turns red. Unlock According to the steps of locking, click the lock button again to unlock. Layout can be edited in the new version of the software, which adds screen editing function and richer graphics. When we learn the image of trigonometric function, we draw the image of trigonometric function in one period with the geometric sketchpad attached to the software. Then, how to draw the image of other periods through translation? At this time, we can consider using copy, paste and translation functions to avoid inconsistent image sizes. Of course, the electronic whiteboard also provides a screen capture function, so that the content running in other software can also be copied to the layout we need through screen capture. The emergence of electronic whiteboard integrates traditional teaching with current information technology, and combines traditional teaching with computer, network and software teaching. While inheriting the educational habits of the past hundred years, it meets the needs of the development of the times and makes up for the defects of traditional multimedia courseware, such as "more presupposition and less generation". Teachers only need to put the preset questions and materials in the resource library when preparing lessons, and call them at any time according to the students' learning situation in class, which is more flexible and convenient. So as to realize the real multimedia teaching. In the usual teaching practice, give full play to the function of electronic whiteboard, make the classroom richer and more substantial, and really improve the teaching quality and efficiency.
