Analysis of the Application of Interactive Whiteboard in Teaching

First, the interactive electronic whiteboard is improving the efficiency of the classroom.


1. Use interactive whiteboard to optimize classroom structure and facilitate flexible implementation of teaching process. Interactive whiteboard can be used to implement teaching process very flexibly. It adds many practical functions than ordinary multimedia, and these functions are general multimedia courseware. Not available in teaching.


 1 annotation, editing function


When using the interactive whiteboard, such as in the PPT courseware or video playback process, you need to do some explanations and text annotations to complete the teaching. In the past class preparation, the teacher needs to use the video processing software to shoot the video. By adding text and the like, the interactive whiteboard can directly mark or write the text without processing. With the interactive whiteboard, you can flexibly introduce multiple types of digital information resources at any time, and flexibly edit, display and control multimedia materials.


2 storage and playback functions


A prominent feature of the interactive whiteboard system is that the contents of the book can be stored. Any text written on the whiteboard, any graphics drawn on the whiteboard, or any inserted content can be saved for later use or shared with other teachers; it can also be printed and distributed to students for publication. After the review or as a review material. This not only improves classroom efficiency, but also helps students achieve knowledge consolidation after class. Using the whiteboard's playback function, you can review and review the content, so that students can consolidate the old knowledge and content, and promote students' learning of new knowledge.


 3 zoom, searchlight and other functions


Some tools in the interactive whiteboard, such as zoom, spotlight, screen capture, etc., can zoom in on specific details, spotlights, and capture images, attracting students' attention and close to teaching needs. The whiteboard's kinetic energy and hidden functions can be used to stimulate students to answer questions again and again, thus making knowledge and concepts more clear in the presentation, and expanding the perspective and way of thinking about problems. By fully invoking these functions of the electronic whiteboard, rich teaching activities can be designed to help students understand and construct knowledge through comparison, induction, highlighting, combing, and playback.


4 drawing function


The interactive whiteboard has a wealth of tools, components, and instrument maps for various disciplines, making it easy for experimental design and students to participate in the learning process. For example, in the physical connection experiment teaching session, when it is necessary to draw the instruments required for the circuit experiment on the whiteboard, the students are very interested and actively participate in the operation because of the simple operation. Students gain an opportunity to participate in practice, fully embodying the new curriculum concept of interaction and participation. The function of media is largely determined by the application of teaching strategies. Teaching strategies also have more flexibility and effectiveness with the advancement of media technology.


2. Electronic whiteboard teaching is conducive to mobilizing the initiative and enthusiasm of students to learn and improve the quality of learning


Classroom teaching is one of the most abundant places where people interact with each other. Teachers can make full use of language, gestures, eye contact and other methods to guide classroom teaching. When applying interactive whiteboard teaching, a whiteboard sensor pen in the teacher's hand is not only a multi-function pen but also a mouse, thus breaking the limitation that the teacher can only use the mouse in front of the computer when using the multimedia courseware teaching. Give teachers more space to make teaching more vivid, strengthen the collision and exchange of ideas between teachers and students, and the teaching effect is twice the result with half the effort.


3. Use interactive whiteboard to facilitate the generation and preservation of classroom dynamic resources, providing a platform for teaching reflection


After the lectures are completed by the interactive whiteboard, the teacher's words, videos, board contents, students' speeches, etc., can be automatically recorded by the system using the corresponding software to form a reusable comprehensive system that includes the whole process of the classroom teaching process. Sexual documents are convenient for teachers to reflect and summarize on teaching; these documents can also be published as teaching resources on the campus network or on the teacher's webpage, and students can download and review the feedback of knowledge; especially if there are many inquiry experiments in the physics discipline, These experiments require students to design inquiry programs, and some students design programs that are valuable classroom dynamic resources that can be used directly or indirectly for teaching.


Second, the use of disadvantages


Interactive whiteboard teaching is a new stage in the development of multimedia teaching, but it cannot be ignored. At present, there are some misunderstandings in interactive whiteboard teaching.


1. Teaching complexity


At present, many teachers do not use the interactive whiteboard as a blackboard, but complicate it into courseware operation. Always spend a lot of time to do the electronic whiteboard courseware in advance, input the situation into the electronic whiteboard in advance, and still be busy with the courseware in the classroom. In this way, the teachers changed from the slaves of the past course teaching to the slaves of the courseware operation under the electronic whiteboard teaching. The electronic whiteboard did not let the teachers liberate from the editing, production and operation of the courseware.


 2. Ignore the autonomy of students


After the interactive whiteboard teaching is introduced into the classroom, the English situation can be generated more randomly. However, many teachers do not realize its superiority. They are always busy setting up the situation in advance. If they are not suitable, they will be drawn in advance, ignoring the autonomy of students. In the long run, it will completely make the electronic whiteboard an adjunct to the classroom and will not achieve positive classroom effects.


The new curriculum advocates the transformation of teaching methods and learning styles. The purpose is to change the situation in which teachers have been instilled and passive learning, and to stimulate students' initiative and enthusiasm for learning, so that students become the main body of learning, exploring and interacting. Get knowledge and improve ability in cooperation. In the teaching of the application of whiteboards, some teachers pay too much attention to the transformation and display of whiteboard content, ignoring the classroom teaching experience and skills accumulated over the years, such as the organization of teaching content, classroom management, and questioning strategies. Neglecting effective enlightenment and cultivating students' problem awareness, cooperation and interaction are more reflected in the teacher's question and student's answer; the teacher invites the student to operate in front of the whiteboard. In some difficult content, there has also been a lecture by the teacher, and the students have no choice but to listen to the scene, which makes the whiteboard fail to really play its advantages and functions.
