Mendeleev, which is a table on which are symbols of chemical elements, serial numbers, element names, electronegativity of elements, relative atomic mass divided into groups, series, periods, series of higher oxides, series of volatile hydrogen compounds, series of lanthanides and for rows of actinides, the table has a series of higher oxides and a series of volatile hydrogen compounds colored in different colors, and combines the rows of lanthanides and rows of actinides with the border of the table (application RU2002119459, IPC G09B 29/00, published March 10, 2004).

A tactile-sound mnemonic is known, comprising a housing with a first surface and a second surface, a first region, a second region and a third region with circuit elements of an object, the first region provided with text made in standard font, the second region provided with text made in Braille. A power supply unit, a memory unit, a digital-to-analog converter, a button, a speaker are introduced into it, while a power supply unit, a memory unit and a digital-to-analog converter are placed in the case, the button is located within the third area to ensure its accessibility from the outside of the case, and the speaker is placed with the ability to listen to the information it emits from the outside of the case, the power supply, a memory unit, a digital-to-analog converter, a button and a speaker are electrically connected to ensure the operability of the device and transmitting from the memory unit to the digital-to-analog converter part of the information recorded in the memory unit and the corresponding button, and transmitting the dynamics converted by the digital-to-analog converter (patent RU135173, IPC G09B 21/00, published on November 27, 2013).

The disadvantages of the well-known mnemonic scheme - a complex design.

Known electronic reference information table D. I. Mendeleev, which is a panel with separate light indication of each element. The panel contains information on 118 elements of the periodic system, which are disassembled by 15 parameters of the main physicochemical properties (http://zarnitza.ru/katalog-tovarov/dost-upnaja-sreda/obuchajushhee-oborudovanie/detskijj-sad-shkola/elektronno -spravochnaja-informatsionnaja-tablitsa-di-mendeleeva-adaptivnyjj-s-sensornym-pultom-upravlenija-i-planshetom-so-shriftom-brajjlja-khimija /). The device is intended for visual work with the periodic system of chemical elements D. I. Mendeleev in educational institutions in the classroom in chemistry, physics and other subjects, the study of which requires information on the properties of chemical elements.

Disadvantages - can not be used in inclusive educational institutions:

- there is no duplication of information in Braille;

- the table is not suitable for independent work with her blind and visually impaired children, because the choice of the studied element is carried out from the remote control with a small LCD screen, and the information is reproduced in the form of a "running line".

Also, the table works only in the "training" mode, i.e. story about the elements, there is no interactive component (feedback, work in the "survey / exam / testing" mode). Food only from a network.

The objective of the utility model is to create a manual for teaching the chemistry of blind and visually impaired children.

The technical result is to increase the effectiveness of teaching chemistry of blind and visually impaired children by combining the tactile and sound channel for transmitting information and providing opportunities for students to work independently with the manual.

The problem is solved, and the technical result is achieved by a tactile-sound training device, made in the form of a quadrangular flat stand, containing a housing with a front and rear panel, and the front panel contains an image of a periodic table D.I. Mendeleev, while in one of the corners of the stand there are controls, including a microcontroller, a speaker, an infrared signal receiver module from the remote control, an evaluation output button, a task repeat button, a toggle switch for operating modes, and LED indicators for the device’s operating modes, the microcontroller being connected to the speaker through mp3 player, other controls are connected directly to the microcontroller, and each element of the table is equipped with a button to enter the element into the microcontroller, signatures ment and its serial number on the Braille system Braille, and the boundaries between the elements of the table are made in relief, and the panels are arranged between the wires that connect each button input element of the table with the microcontroller through a two-dimensional matrix of buttons.

According to the utility model:

- image of the periodic table D.I. Mendeleev applied to a self-adhesive film;

- used the Arduino MEGA microcontroller;

- the front panel is made of plexiglass or PVC;

- configured to connect to a 220 V network through an adapter or to a computer via a USB connector, or to an internal or external battery;

- the body is made of aluminum profile.

The essence is illustrated by drawings, which show the inventive device:

Figure 1 is a General view;

Figure 2 - the upper right corner;

Figure 3 is a view of the front panel from the inside;

Figure 4 is a separate element of the periodic system on the device.

The figures indicate:

1 - designation of controls on a relief dotted braille;

2 - the button for the conclusion of the assessment;

3 - speaker;

4- module receiver infrared signal from the remote control;

5- button to repeat the task;

6-LED indicators of operating modes;

7- toggle switch of operation modes;

8 - serial number of the element on the braille dot font;

9- borders between table elements;

10- button for entering an element into a microcontroller;

11- signatures of the designation of the element on the braille dot font;

12- microcontroller;

13 - mp3 player.

The operation of the device is as follows.

The interactive periodic table is a stand measuring 1200 * 900 * 30, on which a table of chemical elements is applied. Each cell is provided with signatures on a tactile-dot Braille (element number and its designation), a button for launching audio files.

The device can operate in two modes: “training” and “exam”. Switching between them is carried out by the toggle switch (7), LED indicators (6) indicate which mode is currently on - a green LED indicates the learning mode, and red - about the "exam" mode.

In the “learning” mode, blind schoolchildren can study the periodic system of chemical elements, “reading” information from the tablets on the braille-relief Braille, which are provided with the designations of the elements, their serial numbers, numbering groups and periods. To facilitate navigation on the table, the borders (9) between the elements are made embossed. To obtain information about any item, the student presses the button (10), the microcontroller (12) receives the signal from the button, calculates its correspondence to the serial number of the item from the database and, giving the command to the mp3 player (13), starts an audio file with a story about the selected item. Information includes Russian and Latin names, relative atomic mass, serial number, position in the table (period and series) and can be expanded at the request of the customer.

In the "exam" mode, the manual can work in the general survey mode and in several sub-modes.

When working in the general survey mode, the manual randomly names the element that the student should find and mark by pressing the corresponding button (10), the manual announces whether the answer is correct, in the case of an incorrect decision, offers to answer again until the student enters the element correctly. If the student forgot the task in the search process, when the button (5) is pressed, the manual repeats the task. At any moment of work in the general survey mode, you can click on the evaluation output button (2). The controller, evaluating the ratio of correct answers to the number of incorrect answers, displays and announces the score on a 5-point scale.

In addition, the survey can be conducted in the following sub-modes: “Inert gases”, “Alkaline earth metals”, “Transition metals”, “Alkaline metals”, “All non-metals”. Switching between modes is done using an infrared remote control (not shown). When working in these sub-modes, the manual asks you to enter all the elements of the named groups and automatically displays the rating. The volume of the played audio files is also adjustable using the remote control.

The borders between the "cells" of the table are made convex so that they can be identified by touch. The work of the table provides not only the “training” mode, but also the “exam” mode (their indication is carried out by red and green LEDs, respectively). When working in it, the program asks to find a randomly selected item, you need to answer by pressing the button in the corresponding "cell" of the table. The system "voices" the correct answer or not, and after pressing a special button puts a rating for the conducted "survey". All controls along with the speaker are placed in the upper right corner of the table. The system is powered from a 220 V network through an adapter. Her work is possible from a built-in or external battery (at the request of the institution acquiring the table), or from a computer via a USB connector.

Benefits of the utility model:

- involves not only the audio, but also the tactile channel for obtaining information by duplicating information in Braille;

- works in an interactive format: in addition to the training mode, an “exam” mode with several survey options is provided;

- the manual is convenient both for self-study (its size corresponds to the growth and range of hands of the middle school student), and for the teacher to work with the class;

- the manual is universal and can be used both in special schools for the blind and visually impaired, and in ordinary educational institutions;

- power can be supplied not only from a 220 V network through an adapter, but also from a built-in or external battery, or from a computer via a USB connector;

- the table is easy to manufacture, has a low cost.

Thus, an increase in the effectiveness of teaching chemistry of blind and visually impaired children is achieved by combining the tactile and sound channel for transmitting information and providing opportunities for students to work independently with the manual.
