Types of interactive whiteboards. Interactive whiteboard - its features and benefits

Considered a technological marvel and the privilege of a couple of model private schools a decade ago, the device is now being used to teach subjects ranging from biology to math and foreign languages. The interactive whiteboard is gradually becoming not just a fashion accessory or an attractive toy, but an integral part of educational process.

What is an interactive whiteboard?

In fact, this is a large touch screen that is used in conjunction with a computer and a projector. The image from the computer is projected onto the board, after which you can work with all computer programs without leaving it. Special software expands the user's capabilities: from simple drawing on a virtual surface to adding information and objects found on the Internet, creating presentations, demonstrating experiments and working with video files.

How to work with an interactive whiteboard?

After connecting the board to a computer and a projector, just touch the surface with a stylus or finger to start working. Depending on the software and the tasks that the user sets for himself, mastering all the functions may require more or less time, but the basic principle of operation is intuitive and does not require special training. Using the whiteboard, you can open files and applications on your computer, surf the web, make notes over images, websites, maps, and other objects, and, of course, create your own virtual presentations and lessons.

What are the benefits of using interactive whiteboard at school?

To make the learning process as effective as possible, it is important to use the main human sensory systems - visual and auditory. The modern generation of schoolchildren who grew up on computers and smartphones are accustomed to the visual presentation of information, so the interactive whiteboard will not only attract their attention, but also help them better understand and remember the material .

The interactive whiteboard allows students to touch the picture to select the correct answer or solve a problem, simulate a chemistry experiment or find desired object on the map. All this makes the information more visual, creates a creative atmosphere in the classroom, stimulates group discussions.

In turn, teachers using the interactive whiteboard can experiment with learning styles, focus on the needs of different age groups and find the information they need more easily. At the same time, it is much more convenient to create your own methodological base, saving illustrative materials (text and multimedia files, tables, diagrams, images from the Internet, geographic Maps etc.) and adapting them for different audiences. These "blanks" help to maintain fast paced lesson, because the teacher does not need to spend time writing large amounts of text on the board.

Students can save and print all materials in order to return to them at home or in the next classes, study the missed material, and test their knowledge.

How to choose an interactive whiteboard for school?

It should be remembered that there are always many children in the classroom, so the surface of the board must be strong and durable, resistant to scratches and mechanical damage. Another necessary requirement for the surface is haze to avoid eye-tiring glare. It has such properties. She will become indispensable assistant when conducting lessons and additional training sessions for various age groups - from kindergarten to higher education.

The size of the board should be large, as many students suffer from myopia (the recommended diagonal is 78-82 inches).

And, of course, special attention should be paid to quality, since it is on him that the effectiveness of the work of the teacher and his students largely depends.

If you can't choose the right interactive whiteboard - our experts will help!

Nowadays more and more school classes, institute classrooms, offices of small and large companies are equipped with interactive whiteboards. An interactive whiteboard is usually called a touch device designed to display graphic and video information. On the interactive whiteboard, you can work with a wide variety of data formats, display documents, website pages, images, videos, photos, and perform interactive tasks and lessons. For comfortable and productive work with an electronic board, it is necessary to correctly approach the choice of a device model. Below is a list of the most common mistakes which should be avoided.

1. Choosing an interactive whiteboard with the wrong technology
Interactive whiteboards work using one of the following technologies: electromagnetic, optical and infrared. Electromagnetic technology interactive whiteboards display information written using special markers included in the kit. Boards that have an infrared or optical principle of operation allow you to write with your finger or any other opaque object such as a pen or pointer. Boards on electromagnetic technology - no. Consider the number of hours per day during which the board will be used: if it is a whole day, then it is much more convenient to write or draw with a special ergonomic marker, and not to drive your finger over the device, since when using a marker, the hand gets tired much less. There are also disadvantages: if the marker is lost, you will have to order a new one.

In order not to make a mistake when choosing a digital board, you should try out several different options and choose the most convenient for you personally and for your needs.

2. The number of users simultaneously working with the interactive whiteboard is not taken into account
Modern models of interactive whiteboards allow multiple users to work simultaneously. For implementation joint work on the electronic board, you need to decide how many users will simultaneously work on one board. Depending on the answer to this question, a board is selected according to the Multi-touch and Multi-User parameters. Just in case, it is better to take a board with a margin for the number of users - this may come in handy in the future.

3. Lack of anti-vandal, protected surface
If the board is bought for educational needs - in a kindergarten, school or institute, where there are many active children and youth, it is better to choose a device with an anti-vandal design. Keep in mind that children can inadvertently damage the board, hit it, or catch it with a backpack or clothing. Modern interactive whiteboards designed for education or in public places Equipped with anti-vandal surface, which can guarantee the safety of the equipment.

4. Savings on the purchase of a mobile stand on wheels
When purchasing an interactive whiteboard, you should consider the place of its future placement. It is necessary to decide in advance whether the board will be permanently located in the same classroom or whether it will need to be moved from room to room. If the board is not planned to be moved during operation, then the fasteners included in the kit will be enough. But if the equipment will be used in different rooms, it is more logical to get a branded mobile stand on wheels, suitable for a specific model of the board.

5. Purchase a glossy interactive whiteboard
Interactive whiteboards do not work without projectors, therefore, when choosing equipment, it is necessary to take into account the fact that a glossy surface will create glare that negatively affects the vision of both teachers and students. In order to protect eyesight, it is necessary to purchase boards exclusively with a matte surface.

6. Incorrect placement and installation of the interactive whiteboard
It is better to entrust the installation of an interactive whiteboard to professionals with experience similar work. Firstly, the safety of both the teacher and the children working with the interactive whiteboard depends on the installation. Secondly, a professional installer will be able to determine at what height the board should be for comfortable work. It is worth considering the average height of users who will work with an interactive whiteboard in the future.

7. Purchasing an interactive whiteboard without taking into account the features of a projector, laptop or computer
In conjunction with an interactive whiteboard, a laptop or computer connected to the projector is always used. As a rule, modern models of interactive whiteboards do not need additional power from the network, which makes them especially safe - this is important when it comes to using equipment in a classroom with children. All modern models of interactive whiteboards are connected to a laptop or computer via a USB connector; a projector also connected to a PC shines on them. Therefore, it is important to take into account the features of the "auxiliary" equipment.

8. Purchasing an interactive whiteboard without the necessary software
Software and drivers are always included with the board. Different manufacturers supply different software, which may lack certain features that a particular user needs. As a rule, the standard set of programs includes an interactive protractor, a compass, a ruler, and various programs for creating and conducting interactive lessons and presentations.

9. Incorrect selection of the projector required for the operation of the interactive whiteboard
For any interactive whiteboard necessary condition is the presence of a projector of sufficient power, which is selected based on the illumination parameters of the room where it is planned to install the board. In most cases, the projection device is placed under the ceiling so that there are no shadows from people working with the interactive whiteboard. best choice in this case, it will become a short throw type projector.

When choosing an electronic whiteboard for educational or business needs, you should consult with specialists who have experience in installing and using interactive equipment.

Interactive whiteboards

Interactive technologies have proved their worth in educational processes, in the organization of production, as well as in some specialized institutions and organizations. Modern man direct participation in all these processes is required, but at the same time he does not want to spend a lot of effort on this. In addition, a number of additional requirements are imposed on these devices: they must be compact and inexpensive. There is such a solution - these are interactive whiteboards, which appeared in Russia in 1991.

Fully functioning interactive whiteboards typically include 4 components:

· a computer

· multimedia projector

appropriate software

and the interactive whiteboard itself, which can also be equipped with a built-in printer

The image from the computer monitor is transmitted through the projector to the interactive whiteboard, and touches on its surface are sent back to the computer using a cable or via wireless communication interfaces and processed by special software.

Types of interactive whiteboards

According to the main characteristics, there are interactive whiteboards for direct or rear projection.

In forward projection, the projector is directly in front of the surface of the interactive whiteboard, in reverse projection, behind it. Separate models of interactive whiteboards can be equipped with special pocket personal computers for data exchange. There are also expensive models of interactive whiteboards that do not use a projector, but are a large touch plasma panel.

There are three types of interactive whiteboards:

Boards fixing the resistance of the surface when touched.

Such boards have a soft and flexible surface, consisting of two parts. The material that fixes the resistance is separated by a small gap from the rest of the surface of the board and transmits signals to the computer when a special membrane is triggered. Such boards can be controlled not only by special markers, but also by simply touching the board with a hand or pointer.

Special markers can also be configured (using the supplied software (software)) to display different colors. Such boards are very suitable for schools, as they are reliable and do not require any special devices that can get lost or broken.

Boards fixing electromagnetic impulses

These boards are similar to traditional boards and have a hard surface. Management is carried out by means of special electromagnetic markers powered by batteries. The surface of the board is covered with a grid of thin wires that fix the small magnetic field emitted by the marker.

Laser boards have a solid work surface with infrared laser scanners mounted on the surface

These scanners detect the movement of a special pen, encoded color and transmit them to a computer. Close to this technology are DViT (Digital Vision Touch) boards, which use small digital video cameras located at the corners of the screen and recording every touch on it.

A microscope, camera, digital camera or video camera. And with all the displayed materials, you can work productively right during the lesson. For the teacher, a supply of visual and video material in preparation for the lesson with the help of this technical means unlimited, as there are many learning resources on any topic, and in various online libraries you can find specific visual materials and use them repeatedly.

Now teachers simply do not need to worry about the safety of paper maps, posters and teaching aids. They will simply be unnecessary. All the work carried out during the lecture with all the notes and notes made on the board can be saved on a computer for later viewing and analysis, including as a video recording.

The interactive whiteboard allows you to reproduce information in a format accessible to all students. Working on the board with an electronic marker like a mouse, the teacher can quickly and clearly show one or another method of work.

The greatest effect can be obtained by a teacher who uses all the features of the board. An interactive board with the help of a special marker allows you to move drawings, photographs and texts on its surface, copy them, rotate, change the size and shape. Using such a marker, you can not only draw on the surface of the board, but also control computer programs, press buttons, select and drag objects. The marker in this case replaces computer mouse. This feature allows you to use many computer programs, including most existing multimedia computer educational programs.

Remotely, controlling the presentation, the teacher has more possibilities provide individual assistance to students, because all the constructions, diagrams that he had to complete on the board during the lecture are already on the slides of the presentation.

A teacher working with an interactive whiteboard can increase the level of understanding of the material through a combination of various forms transmission of information - visual, sound and tactile. During the lecture, he can use bright, multi-color schemes and graphics, animation accompanied by sound, interactive elements that respond to the actions of the teacher or student. If necessary, you can simply increase one or another element drawn on the surface of the board with one movement of your hand. Competent work with an interactive whiteboard also allows you to optimize the educational process.

The interactive whiteboard lowers the psychological barrier, allowing students to overcome their fear of technology and start using it in the classroom. modern technologies.

An interactive whiteboard, depending on the manufacturer, can be equipped with special interactive tools. Let's consider the functionality of some devices on the example of the ACTIVInspire interactive whiteboard from Promethean.

1. What is interactive equipment

Interactive (from the English interactive - interacting) - interaction with the user in the process of work and immediate response to the user's action.

Every schoolchild knows exactly what an interactive whiteboard is, because it is not for nothing that the government has allocated money to provide all schools in the country with this device. From now on, teachers can forget about the technique of the 20th century called "graphic projector" and "transparency projector". However, the device will be useful not only for schoolchildren, but also for adults, both at work and at home. The focus of the article is an interactive whiteboard: how to work with it, positive and negative sides its use.

What is it and how does it work?

The first question that a person has when he hears the phrase "interactive whiteboard" is how to work with it? At first glance, the device seems very complex and inaccessible to many users. However, having figured it out, we can conclude that this is another technical innovation, which can be mastered not only by a child, but also by an elderly person of conservative views.

The kit includes a projector and a touchscreen They are simultaneously connected to a personal computer or laptop. Some models are equipped with a special laser pointer that can affect the sensitive screen. Accordingly, the projector transmits a picture to the screen, and the user, using a pointer, pen or fingers, touching the screen, exercises full control over the contents of the picture.

A bit about technology

Different manufacturers, as is customary in the IT industry, created a device using own technologies that make them slightly different from their competitors. Naturally, stating that their development is much more efficient. We'll have to figure out the differences.

1. Electromagnetic technology. The solid surface of the interactive whiteboard has a multi-layer structure that is very sensitive to touch. The board's response time, as well as its resolution, is very high, allowing it to respond quickly to touch. To work, you need a special marker, and performance depends directly on the power of the computer.
2. laser technology. Two infrared lasers read information about the user's actions by determining the coordinates of the touch. If you accidentally block the beam, you can block the use of the interactive whiteboard.
3. Ultrasonic technology. The principle of operation differs from laser technology only by the use of ultrasound instead of a laser beam.

What to look for when buying

Let the advertisement say that the device is universal and connection is possible to any computer, but this is for the cost developed countries, where there are no problems with the annual renewal of the fleet of computers and laptops. Judging by the reviews of the owners, they are often concerned about one question in the topic "Interactive whiteboard": how to work with it if there is no technical possibility to connect it to computer technology? Before making a purchase, you need to make sure that the necessary interfaces are available. Most inexpensive devices have the old service port for connecting to a computer - RS-232, which most laptops do not have. The new interactive whiteboards are only equipped with a Bluetooth module, which is not available on personal computers. Conclusion - you need to select the device individually for yourself and strive to ensure that the interactive whiteboard has a popular USB interface, with which there will never be problems.

Using the interactive whiteboard at school

Any teacher knows that the assimilation of the material by the student depends entirely on his attention in the learning process. Not in vain, along with pedagogy, future teachers study oratory that keeps attention a large number children by changing intonation, volume and speed of speech. However, this is not enough. Often teachers resort to involving students in their own designed games, participating in which the child receives information through association and his own memory. The games of the 20th century included all kinds of drawings on a board or posters, cutting out models related to an object from cardboard, and similar improvised means.

An interactive whiteboard in elementary school allows the teacher to involve the whole class in the work without much effort. Thanks to a huge number specialized programs, you can change the course of the lesson in seconds when students lose interest and include something else, more interesting.

From theory to practice in education

As you know, if there is a need and resources, there will always be an offer and applies to ready-made school programs on various subjects that can be found on the Internet. But, as you know, any teacher strives to present his subject in such a way that it is understandable to all students in the class, focusing on the “weak link”. Ready-made lessons with an interactive whiteboard in such cases will not be effective. You need to develop a plan from scratch on your own. And there are no difficulties in this.

1. Using a package Microsoft office in particular PowerPoint. Using ready-made templates, creating a visual presentation will be easy.
2. Smart software. The interactive whiteboard comes with this wonderful program from the start. She is only interested in early stages. Free drawing and working with text quickly get bored.
3. Independent development of programs using object-oriented programming languages, including WEB. This is the “aerobatics” of any teacher, although it may take more than one month to master the language, but the result is worth the effort.

An example of creating a lesson

The example will use an interactive whiteboard program. Microsoft PowerPoint. Lesson topic for primary school: "Computer device". When opening PowerPoint, select " Ready template” and find “Widescreen Presentation”. The eight-slide presentation layout contains complete instructions for work in the program. It is necessary to add a thematic picture to each slide, which can be downloaded from the Internet, and make a description for it. Photos of the processor, motherboard, RAM, hard drive, video card, power supply, case and all kinds of peripherals should be present separately. You also need to find a picture of the computer assembly, where you can see how and where the components are installed in the computer. When creating a presentation, you need to add a graphic field on each slide to be able to add information in the learning process - drawing visual arrows, footnotes and other descriptions. A simple presentation will allow even a child to understand the principle of action and (using an interactive whiteboard) will be achieved.

Simple equipment for the little ones

The children's interactive whiteboard is gaining great popularity in the world. It is easier for a child to learn with a device that has feedback than with a regular book. A simple and inexpensive solution for the little ones can be a “talking Buccaneer” toy. Although the principle of its design is far from expensive equipment, the learning process is no less interesting for both children and adults. This interactive whiteboard will help your child quickly learn the alphabet and allow them to read simple words and suggestions. easel on reverse side toys will reveal the talent of the artist, and the sound accompaniment of keystrokes will not let you lose interest in the device. The interactive whiteboard for the little ones is made of durable plastic, it is not so easy to break it, so it will last a very long time.

A worthy solution for preschool children

Parents will also be interested in KidzBoard - an interactive whiteboard, the price of which is much higher than toys, but the functionality allows even adults to work with it. The board uses infrared technology and is designed to work with a projector and a computer. The design is quite convenient, you can adjust the location of the board in height, focusing on the growth of the child. The surface of the board allows you to work both with a marker and with any object for drawing. It is even possible to enter with a finger.

Distinctive feature KidzBoard is supplied with the device proprietary program for an interactive whiteboard called KidzFlow. Large allows you to create your own lessons both from scratch and using special templates. The program has a built-in system that perfectly copes with children's "doodles". Its cost is about 50,000 rubles.

Professional use

Having found out that the interactive whiteboard in elementary school is an indispensable tool for learning, it is worth paying attention to useful functions for adults. For a long time, presentations and seminars are not complete without the use of projectors, but this technology is one-sided and is used as a visual aid for a large number of viewers. Naturally, for a better perception of information, feedback is important. During the seminars, many participants will always have questions that require detailed explanations. Using an interactive whiteboard will allow you to make changes to any presentation, directing learning in a direction that is understandable to others.

What is interesting for business

Judging by the numerous reviews of trainers who conduct training seminars for people of medium and large businesses, the Board Triumph interactive whiteboard has proven to be excellent. And it's not even about the huge screen resolution (4096x4096 dpi), which allows you to see a high-quality picture from a long distance. A distinctive feature of this device is an interesting package, which includes 31 remote control remote control. Using these devices, you can receive feedback from all participants during the conference by polling. There are several buttons on the remote that the trainer can program to suit. certain actions on the board using the software supplied with the device.

Business use case

I would like to see an example of how and where an interactive whiteboard is used. How to work with her at the training on managing small and medium-sized businesses? Having finished the lecture, any teacher proceeds to practice. For trainings, there is always a set of economic and strategic games, when people are divided into several groups and offered to perform a series of activities aimed at achieving a result. Using an interactive whiteboard, participants will not have to move around the room, experiencing discomfort. All necessary information, which can be changed dynamically, is on the screen.

Anyone can make their own changes, and they will be immediately available to all participants in the training. The use of an interactive whiteboard prevents cheating, and also allows you to record all the actions of the participants, allowing you to view the seminar at any convenient time.

Finally

It is clear that for many people who want to purchase a device called "interactive whiteboard", the price will be the main factor in the choice. Yes, the purchase is expensive. However, it is worth noting that it is long-term, since the equipment will last a very long time. long term. Therefore, if there is a need to use an interactive whiteboard, first of all, you need to make a list of necessary requirements, and only then look for the right device for your budget. But not vice versa. Otherwise, as often happens with many people, the lack of the necessary functionality will put an end to the use of an interactive whiteboard in business and education.
