Summary of interactive whiteboard with a computer information communication, the whiteboard connected to a computer, and the projector will use content on your computer screen projected onto the whiteboard, with the support of specialized applications under a large screen can be constructed, interactive, collaborative meetings or teaching environment. Using specific positioning pen instead of a mouse to operate on the whiteboard, you can run any application, you can edit the file, notes, save, etc. on a computer with a keyboard and mouse can be achieved nothing. Composed of operating system integration hardware electronic sensor whiteboard (White Board) and software whiteboard. Its core component consists of electronic sensors whiteboard, stylus, computer and projector components. Electronic sensor whiteboard is a blackboard with a normal size, large-sensitive screen in computer hardware and software support of the work, which acts as a computer monitor and replace the traditional blackboard. Electronic stylus pen assume the dual function whiteboard and computer mouse, and its role to replace the traditional chalk. Teacher or student with a stylus directly on the whiteboard (equivalent to the traditional teaching of teachers and students operate on a blackboard with chalk): write or call a variety of software and feedback to the computer through electromagnetic induction and speedy adoption of the projector is projected to electronic whiteboard. Whiteboard operating system is present in the computer in a software platform that not only supports the exchange of information between man and whiteboard, computer, projector between, and it comes with a powerful subject material library and resource production tool library, and is a Compatible operating smart various software platforms, teachers are free to call a variety of teaching materials or application software on the whiteboard. Whiteboard set traditional blackboard, computers, projectors and other functions in one, so that teachers use very convenient. Interactive whiteboard also support the copy, the printer is directly connected to the whiteboard, writing on the blackboard whiteboard pen through specific, when you need to print, simply press the print button on the front panel can be realized in color or black and white printing. You can also use as a teaching whiteboard, whiteboard connects to the computer at this time is equivalent to an area of ??special whiteboard large tablet, can be above any writing, painting and instantly displayed on a computer, save the file as a graphic file. This function generally requires a dedicated application support. If the interactive whiteboard can be carried out by specific applications through the network with other offices, meeting rooms AC, network meetings. Interactive whiteboard can be divided into five categories according to the principle: electromagnetic induction, infrared, ultrasound, pressure-sensitive resistors, CCD and so on. Technology is divided into electromagnetic induction, infrared sensors, pressure sensors, ultrasonic sensing, image sensor type and so on. Each technology has different characteristics and advantages in the market occupies a certain share. Analysis of international authoritative market research agency indicated in recent years on the international market, using infrared sensing technology and electromagnetic induction technology whiteboard gradually dominate the market, occupies more than half of the market share, followed by the sense of pressure and ultrasonic transmission sensing technology, occupy market share of about 1/6. Foreign Panasonic, Toshiba, PLUS Truer other brands, domestic brands have hung together, the dragon and other brands. Positioning principle resistive technology use pressure-sensitive input whiteboard, the equivalent of a touch screen computer teacher with a finger or brush strokes and realistic options screen, the computer automatically handles quite operation. In fact, this has two pressure-sensitive whiteboard inside the film, when the board's surface at a point under pressure, short circuit, the electronic controller detects the coordinates of the two film-forming pressure points value at this point, through the interface to send as computer. Laser technology uses a laser to track the principles of the whiteboard on each side of a laser transmitter. After whiteboard start, the laser transmitter emits laser fire whiteboard surface characteristics laser pen has a sense of function, so the teachers use a photosensitive pen operation on the whiteboard, laser transmitter scans the photosensitive pen position. Electromagnetic induction technology whiteboard using a pen can emit electromagnetic waves, lined in white receiving coil membrane both horizontally and vertically. When the pen is close to the receiving coil film, Chamber of Commerce induction coil to pen emits electromagnetic waves. Pen from the more recent, induction coil film to higher electric. Infrared technology is received by the clouds in the display area around the infrared emission and scanning grid tubes horizontal and vertical directions, forming a network scanning plane, when there are objects blocking a live grid of horizontal and vertical scanning lines, you can OK X, Y coordinate position is blocked by the infrared horizontal and vertical directions. Ultrasound technology ultrasonic receiver means disposed at a fixed distance from the two distributed on both sides of the screen, the pen is used for positioning an ultrasonic transmitter, ultrasonic waves along the surface of the screen when the pen moving on the surface of the screen, is transmitted to the receiver detected , by the received ultrasonic wave can be converted from the time T and receiver two. Electromagnetic induction: Fundamentals: radio frequency (RF) principles, core sensor installed in the white plate, specific frequency signals emitted by receiving electromagnetic pen achieve positioning advantages: positioning accuracy, high precision, high reliability, long life, fast response, writing process pressure sensitive, white pen support the right mouse button and other functions, easy to implement operational shortcomings of the computer: You must use special pens, maintenance complex and difficult to operate, larger radiation on the human body, the human body is not appropriate, especially women, children long-term use; IR Technology: Fundamentals: Infrared principle, whiteboard surrounding infrared tube infrared light to detect objects blocking achieve positioning advantages: positioning accuracy, high precision, no special pen, long life, fast response, simple maintenance, safety and environmental protection, no radiation; Disadvantages: No pressure sensitive response, almost no other shortcomings; resistor Grip: Fundamentals: resistive film technology, pressure sensitive positioning advantages sense resistor value: relative positioning accurate, no special pen Disadvantages: poor durability, fear of scratches, the reaction is slow, unable to make large area, whiteboard pen does not support the right mouse button and other functions, the more difficult for computer operations divided according to the type of installation: wall-mounted, slide style, mobile, closet type. Basic parameters 1) Computer: Interface type refers to the whiteboard with a computer system in what way to connect. Common interface types have parallel port (also known as IEEE 1284) and serial port (also known as RS-232 interface) and USB interfaces. Decision on core quality whiteboard technology, but technology alone does not represent the entire product. 2) Stability: Stability is the stability of the entire product (including hardware), by means of market experience and the old user experience, easy to determine product stability; 3) Sensitivity: on a whiteboard to draw a line, if the line of continuous sex is not strong, it shows the sensitivity is not high; 4) Accuracy: Accuracy refers to after calibration, the mouse cursor tip and the degree of overlap stylus tip; 5) Resolution: Resolution refers to the number of points for each line ( or pixels) number. Usually along the horizontal and vertical edges of a screen or monitor to indicate the number of points; 6) Output: whiteboard can be written on the whiteboard content scanning and print out a certain way. Print mode output generally have thermal, inkjet and ribbons; 7) Panel Number: Under normal circumstances whiteboard will feature 1-4 of the panels, the number of panels in two or more screens can facilitate circulation; 8) Panel Size: refers to the actual size of the whiteboard, the unit is mm, usually refers to the length × width whiteboard; 9) Effective reading size: refers to the whiteboard can write effective size used in this area can be any writing and copying output, its size is generally smaller in size than the actual panel; 10) Copy Speed: Speed ??is the number of sheets of copy whiteboard can copy per minute, its unit is sheets / min; 11) Continuous copy number of sheets : continuous replication refers to the same document does not require multiple set maximum number of continuous replication whiteboard once completed, this product represents the maximum capacity of continuous replication. Influence of teaching and teacher professional development (1) The main difference between the electronic interactive whiteboard is different from other teaching multimedia interactive whiteboard. Electronic interactive whiteboard technology, interactive classroom teacher-student interaction, students interaction provides the technical possibility and convenience for the establishment of a student learning the technological foundation for the classroom teaching center. Traditional multimedia courseware is to demonstrate more features, courseware demonstration process, students can not participate, because the content can not be changed courseware. The whiteboard technology to produce "courseware" (or rather digital lesson plans for teachers) as a teacher-student interaction and participation in the teaching process to provide a great convenience. The teaching process, students can change and enrich teachers' original "courseware" content, whether it is the correct understanding of the knowledge of the students, or the wrong answer, as long as the operation on the whiteboard, the system will automatically store valuable information, thereby generating each teacher for each class of personalized "courseware" (or rather, is the digital recording of the entire teaching process), and has become an important resource for the future of teaching. (2) electronic interactive whiteboard as a resource-based teaching and learning activities to provide technical support. Effective use of teaching resources are proficient in technology, an important part of the whiteboard. Whiteboard system for each subject material prepared a lot of discipline, but it is not readily available, fixed courseware, teachers must form their own lesson plans according to their specific instructional design and objectives, the application repository material, whiteboards enable teachers to use technology resources the process of self-generating assets in the library of digital lesson plans has become very convenient. Furthermore, since whiteboard system compatible with Microsoft's various software applications, so that teachers can also directly access resources to find courses on the whiteboard. (3) operating system extension whiteboard, enriching the traditional tools of computer multimedia capabilities, more to improve the visual effect. For example, Whiteboard tool unique drag and drop functionality, camera, hidden features, pull the curtain function, painted features, matching, real-time feedback functions, and more to improve the visual effect, more conducive to stimulate students' interest, to mobilize Multiple Intelligence to actively participate in the learning process. (4) improve the effectiveness of teaching, teaching to make a stronger plan. Teachers not only teach with white, while white is a good helper teacher preparation. Teachers can put the entire teaching process on the whiteboard are stored in their own folder, to become their own electronic archives and teaching of curriculum resources, to become teachers in the future lectures, summary and reflection and other resource base for teachers' professional development. (5) electronic interactive whiteboard teaching and research carried out in favor of a team of teachers. Studies have shown that if teachers from teaching and research team in the application of the whiteboard teaching, to explore the whiteboard teaching methods and strategies, such as team teaching research methods than the teachers themselves isolated whiteboard teaching, more conducive to promoting the professional development of teachers. Effect of interactive whiteboards on student learning (1) to improve students' attention and understanding. With respect to a variety of teaching functions of the traditional blackboard teaching whiteboard visual effects, such as color, hide, animation, etc., can greatly attract students' attention, and the use of multiple intelligence theory to help students better understand and master the knowledge. In particular, learning some of the more abstract knowledge and concepts, the whiteboard to provide students with a variety of analytical and problem-solving methods and ideas. (2) to facilitate students review previous knowledge content and promote students to master new knowledge. Since conventional whiteboards teachers can record lectures and procedures (including students' learning process), help students consolidate and memories of the old knowledge and concepts to promote students to learn and master new knowledge. (3) to mobilize the students in the classroom active learning enthusiasm and participation. Studies have shown that, due to the whiteboard teaching more emphasis on the participation of students and teachers and students, life and interaction, so that the original classroom teaching high school students do not pay attention, do tricks, free to speak and so greatly reduced, improving the quality of student learning, learning motivation and learning self-confidence. Advantages of the use of the advantages and disadvantages of the application of interactive whiteboard products in small and medium education has been a good application, the user is also given to the whiteboard teaching full recognition: (1) the traditional blackboard whiteboard technology, projectors, computer together become an important means of classroom teaching, teaching a unified platform, greatly improving the efficiency of classroom teaching. Interactive concept (2) whiteboard design and operational characteristics and interactive whiteboard technology itself as a transformative teaching methods, classroom teaching to promote reforms in favor among teachers and students, between students and students interactive learning, teaching supplement the gaps in individual teaching from multimedia presentations to network conditions between conducive to promoting the integration of information technology and subject teaching. (3) whiteboard technology set text, sound, pictures, video in one, as a new teaching tool, not only help to stimulate students' interest in learning, but also make students more easily and conveniently. (4) Whiteboard not only on the hardware device to provide a platform for teaching support, while the whiteboard software designed to provide a new idea for our teaching: for example, there are camera, pull the curtain, hidden, resource library storage, internet connection and many other features that make teachers more convenient, lively and interesting. (5) whiteboards provide a great resource storage space, easy to teachers teaching resources, accumulation and reflect on the teaching process, to facilitate teaching experience summary and order, promote teachers' professional development and improvement, and saves teachers time to prepare. But lack of application of affirmative whiteboard teaching based on the advantages, we feel there are still many different whiteboard manufacturers place more or less needs to be some appropriate improvements in some aspects of the following. First, whiteboard hardware technology could be improved. (1) Stylus: some products feature the right to do so; double-click to do so; recognition is not very good; easily broken; (2) the whiteboard and computer compatibility: incompatible with domestic some laptops; (3) Whiteboard interface with other software interface switching frequency, easy to hang; (4) the whiteboard comes with Chinese font problem. Second, whiteboard technical support need to be improved. Currently whiteboard surface in terms of service coverage to be expanded, especially domestic brands, if there is a problem it is technically difficult to obtain timely resolution, which is currently the greatest concern of the school, so I do not mass purchases. Third, whiteboard resources and localization issue has become the biggest obstacle to Chinese teachers and students to use. At present, many foreign own resources whiteboard products are mostly not suitable for Chinese teaching content, the urgent need to join the Chinese localization of teaching resources. In addition, the need for whiteboard finished treatment, or part of the Chinese teachers will be stopped at the whiteboard users. Fourth, the use of the whiteboard teaching. There are many teachers raised, whiteboards for use in small groups of 40 people or less. In the case of small class sizes, teachers and students, students' interaction more convenient, you can fully interactive whiteboard. If you use more than 40 large classes, teachers and students interaction difficulties, not only difficult to play interactive whiteboard, and because of the size limit whiteboard, sitting in the back of student teaching is not easy to see the contents of a whiteboard presentation. Fifth, because of the high economic costs whiteboard, investment, therefore, whiteboard practical school in China remains to be further studied. Website: www.ctvhd.cn Tel: 13823196904 QQ: 2537602872
