Eight common functions of interactive electronic whiteboard
Abstract: Electronic whiteboard is a collection of cutting-edge electronic technology, software technology and other high-tech means of research and development of high-tech products, it through the application of electromagnetic induction principle, combined with computers and projectors, can achieve interactive teaching in the classroom. So that teachers completely get rid of the shackles of mouse and keyboard, so that multimedia teaching has a revolutionary change. Our school is fortunate to have an interactive electronic whiteboard, which has been used to carry out some applications in various disciplines in the past semester, and found out some common functions in teaching.
Key words: interactive electronic whiteboard function
Interactive electronic whiteboard is an emerging multimedia teaching equipment, which has the following teaching features: dual integration (in-depth integration of information technology itself with computer technology as the core, organic integration of electronic interactive whiteboard and classroom teaching), multiple interaction (including human-computer interaction, human-human interaction, resource-resource interaction based on teaching application, etc.), easy to learn and use. These characteristics realize the new fusion mode of information technology and subject teaching, bring about the change of teaching content presentation mode, and also bring about the reform of classroom teaching mode.
It has been nearly two semesters since our school introduced the electronic whiteboard into teaching. During this period, I had the honor to participate in the national interactive electronic whiteboard topic seminar of Central Audio-Education Center. In the teaching competition of effective application of information technology and high-quality resources in subject teaching held in Hanjiang District this semester, four teachers of our school used electronic whiteboard to carry out effective teaching competition, and three of them won the first prize and one won the second prize. Electronic whiteboard is a new thing, there are not many experiences available for reference, our teachers in the usual teaching through constant exploration, communication with teachers in brother schools, and so on, summed up some common functions.
First, screen comments, timely feedback
Based on the interactive electronic whiteboard, it provides convenient writing and drawing functions. When applied to Chinese subjects, it can realize the learning mode of students thinking while imagining while drawing, and present the learning process of students reading and thinking as well as the final thinking results. The application of mathematics can present the results of students' practice and thinking, which is convenient for teachers to find problems and evaluate them in time.
For example, in class, teachers use the electronic whiteboard to present the electronic text first, and in the process of explaining, they use the screen annotation function of the electronic whiteboard to add some key words in real time (underline, emphasis, circle, etc.), and use the electronic whiteboard to create a learning environment of student-student interaction and teacher-student interaction. In the interactive exchange of annotation results, in the teacher feedback to clarify the meaning of the method. In the whole process, students are the main body of learning, and the independence and depth of thinking of students are improved in the independent annotation and interactive discussion.
Second, occlusion hiding, batch presentation
Based on the occlusion curtain function provided by the interactive electronic whiteboard, pictures can be poured into the theme background, which is conducive to the creation of the scene. Resources can be presented in batches according to the learning progress, which is not only conducive to the concentration of students, but also effectively guide the development of students' thinking. It is not only practical in the new teaching, but also very useful in the usual practice and review classes.
For example, in the art class "All Kinds of People" in Grade 3 of primary school (online lesson can be viewed at http://v.youku.com/v_show/id_XOTk0NzkxNDg=.html), our school teacher Pan Xia made use of the blocking function of the electronic whiteboard at the beginning of the teaching, and showed the protagonists of "I love my family" one by one. In this way, it effectively guides students' thinking and fully mobilizes students' interest in learning.
Third, drag and drop combination, flexible interaction
Based on the drag-and-drop, magnification and combination functions provided by the interactive electronic whiteboard, students can experience the learning process in drag-and-drop, and show their thinking creation in drag-and-drop combination. In the process of learning, students' learning practice is strengthened, so that students can increase their ability in practice.
In the elementary school math lesson "Translation and rotation", the students could not tell which parts of the small house should be translated. The teacher can use the "drag" function to drag the small house graph to the designated place one by one, dragging while counting, under the teacher's intuitive demonstration drag, the students clearly see the whole moving process, and learn to count the grid method.
Primary school art "Beautiful Collage" (online lesson browse address: http://v.youku.com/v_show/id_XMTAwNTk5NTQw.html) our school teacher Yin Yanli also made use of the drag function on the electronic whiteboard in an interactive form, let students drag graphics, understand the method of drawing tropical fish.
4. Focus on amplification and highlight key points
Based on the photographic and zooming functions provided by the interactive electronic whiteboard, it can focus on the teaching focus, focus on presentation, careful observation, and conducive to the discovery of problems.
For example, in the middle school physics teaching, teachers use the magnifying glass tool of the electronic whiteboard to help students carefully examine the small problems existing in the circuit diagram. In Chinese teaching, the magnifying glass tool is used to magnify the details in the pictures for students to observe, and the ability of students to penetrate the details of things is cultivated.
Five, the process playback, showing the vein
Based on the playback function provided by the interactive electronic whiteboard, it can be applied to the learning of students in various disciplines, which can re-show the learning process and review the vein of thinking, which is conducive to summarizing learning methods and refining methods in learning, fundamentally discovering problems and seizing key problems.
In the lower grade literacy teaching class, the teacher recorded the process of writing Chinese characters, and can replay the process of writing Chinese characters at any time when teaching. Especially after the fan character, the playback function is used to let students watch while practicing, so that students can further clarify the strokes and strokes of Chinese characters, breaking through the difficulty of writing Chinese characters.
Six, mode switch, easy to demonstrate
Based on the interactive electronic whiteboard provides the switching function of three modes, which can be integrated with educational resources to facilitate classroom demonstration and batch painting.
Through mode switching in teaching, teachers can use the electronic whiteboard operation to switch to the ordinary operation mode, and carry out ordinary computer operations, such as playing videos, playing PPT, opening files, etc., without using the mouse and keyboard.
Seven, intelligent drawing, improve efficiency
The electronic whiteboard provides a variety of intelligent tools such as compacts, drawing corners, smart pens, protractors, drawing circles, etc. Teachers do not need to use other tools, a little practice, you can use a pen in the electronic whiteboard is very convenient to draw a very professional, accurate variety of geometric graphics.
These tools not only provide an integrated toolbox for science teaching, but also these tools are the same as real tools when used, which is a realistic simulation operation. In practice, these tools are very popular with teachers and students.
8. Save inventory and accumulate resources
The inventory is based on the resource library function and storage function provided by the interactive electronic whiteboard, which can call resources and accumulate on-site resources at any time during learning, and can store on-site learning resources in a variety of ways to facilitate review and review. Save is the creation of courseware, teaching resources and students' wisdom used by teachers in class, and export it into web pages, pictures and other resources to facilitate students' re-learning or review.
Of course, in addition to the above eight functions, the electronic whiteboard has many other very practical functions, such as timers, players, etc., which can be flexibly selected according to the needs of actual teaching.
We also found some shortcomings in the process of using the electronic whiteboard. For example, when teachers use the software of the whiteboard to import teaching resources, they must normally connect the electronic whiteboard to the computer to carry out the design, which limits the teachers' ability to carry out in the classroom. I hope that manufacturers can continue to improve in the future products to better serve education and teaching.
