The electronic whiteboard was developed from the office whiteboard. The earliest electronic whiteboard was a copy-type electronic whiteboard. With the development of technology and the needs of the market, an interactive whiteboard appeared. The so-called copy-type electronic whiteboard can scan and print the content written on the whiteboard in a certain way by the user's simple operation. Interactive refers to the communication with the computer, that is, the user can operate the computer on the whiteboard, such as opening and closing the application, editing graphics and documents. The interactive whiteboard has the following outstanding advantages in multimedia teaching.
First, using the interactive whiteboard makes it easy to control the material display process. The teacher can control the playback of the presentation material without having to go to the console. This allows the teacher's body language to be fully utilized and avoids the teacher in the classroom. The problem of distracting students from the blackboard to the console.
Second, the use of interactive whiteboard technology can instantly and flexibly introduce multiple types of digital information resources, and can flexibly edit, organize, display and control multimedia materials, which makes the presentation of digital resources more flexible and solves the past multimedia. In the projection system environment, the use of courseware and slideshow teaching materials structure is highly solidified.
Third, the contents of the blackboard can be stored. Any text, graphics, or any images inserted on the whiteboard can be saved to a hard drive or removable storage device for use in the next lesson, next school year, or in another class, or shared with other teachers; or in electronic format or Print it out and distribute it to students for review after class or as a review material.
Fourth, the interactive whiteboard technology makes the previous color monotonous, and the blackboard type that presents the type of material only ends with handwritten text and hand-drawn graphics becomes colorful, and can be freely booked as before, and can display and edit digital pictures and videos, which will have It is conducive to improving students' interest in learning and maintaining their attention.
Fifth, the interactive whiteboard makes the teacher's operation on the computer transparent. It allows students to clearly see how the teacher operates on the software, such as which button or menu was clicked. This makes a lot of sense for the learning of computer software applications. An interactive whiteboard system can be installed in the computer room to assist in the teaching of computer courses.
Sixth, with the interactive whiteboard making the access to the computer more convenient during the teaching process, the whiteboard system is complementary to the network and other computer applications, prompting teachers and students to jointly use the computer as a tool for cognition and discovery, which will certainly build students. New ways of thinking and solving problems. For example, in the Beijing Experimental School participating in the interactive whiteboard research project of the Institute of Distance Education of Capital Normal University, teachers use the interactive whiteboard system to teach the electrical, optical and chemistry courses in the junior high school physics class with virtual simulation software and real experiment. The experiment has achieved excellent results and has been welcomed by students.
Seventh, because the interactive whiteboard can still be used as a traditional blackboard, some older teachers with poor computer skills can apply the basic functions of the whiteboard to teach, and it is easy to overcome the fear. As a new technology, interactive whiteboards are naturally close to teachers. (According to Nantong Education Blog Moonlight Autumn Wind)
