What will the learning tools of the future look like?

You can't learn to write without pens. The future pens are novel in style, versatile in function and more convenient to use.

liquid pencil. Among the writing tools for future students, the ballpoint pen will be used the most. This kind of ballpoint pen is different from the present one. The handwriting written with it can be easily erased with an eraser within two or three hours, but it can't be erased after this time and becomes permanent handwriting. This kind of ballpoint pen is also called "liquid pencil". Its structure is the same as that of ordinary ballpoint pen, but the ink used is different. This kind of ink is made of ground rubber and an organic solvent with low boiling point, which can be completely volatilized within 1 minutes.

photometric ballpoint pen. When working and studying, improper lighting will affect your eyesight. A photometric ballpoint pen can tell you whether the lighting you choose is suitable or not. Its shape is similar to that of an electronic pen, except that three small lights are installed side by side in a small window opened at the upper part of the pen holder, and a button is set on the pen holder. As soon as the button is pressed, the small light will glow. Red light means insufficient illumination, green light means appropriate illumination, and yellow light means too bright illumination.

a ballpoint pen that can calculate. When doing arithmetic or numerical statistics, we often use both calculators and notes. A ballpoint pen that can calculate can combine the two functions. Its shape is slightly thicker than that of ordinary ballpoint pen. The back of the pen is equipped with a micro electronic calculator, and the function keys and LCD are on the pen holder. It can perform mixed operations such as addition, subtraction, multiplication and division, multiplication, fraction, negative number, reciprocal and principal and interest calculation. This pen can be used by bank accountants and statisticians for various business operations, and can also meet the calculation of general engineering design.

Handwritten Typewriter

When taking notes in class or writing letters, use a typewriter to print, which is fast and clear; If the printed font is the same as your own handwritten font, it will be more convenient and friendly. Scientists are developing this handwritten typewriter.

Handwritten typewriters are very similar to personal computer typewriters nowadays. Besides keyboards and printing devices, they also have microcomputers and micro-memories. In the typewriter, the handwriting and radicals of various basic words are pre-stored. When typing, you can print your own font or a writing style composed of various radicals by pressing the keys of the keyboard. If you encounter some uncommon words, just write them with a pen or pencil, temporarily store them, and press the button to print them out.

This handwritten typewriter also has some special functions. If you feel that your handwriting is not good-looking, you can make the font stored in the typewriter deform by computer processing, just like artistically making your font, without losing the personality of the original font.

This typewriter has been successfully developed in Japan. It stores Japanese pseudonyms and Chinese characters. Through computer control, the printing speed is faster than handwriting. Therefore, this handwritten typewriter not only has the functions of text editing and recording, but also reproduces the writer's personality and improves the typing speed, which has become a good helper for shorthand in the future.

new stationery "doll" computer

The most fashionable and commonly used stationery for future students is computer. It is not only a good helper for all students to master knowledge, but also a good teacher to develop their intelligence and improve their ability. Children use a doll computer, which is a small household computer named "Doll". Its size is only as big as three primary school textbooks. Just plug it into the antenna socket of the TV set at home and you can use it. Doll computer uses games to teach children literacy, arithmetic, painting, music and so on. Its teaching attitude is excellent, and it never gets impatient or scolds loudly. Instead, it gives counseling step by step with beautiful pictures and beautiful words.

When entering middle school, computers are stationery that students can't leave for a moment. In the future, students will not only receive computer operation training, master the basic computer language, use it to write and do homework, but also be able to independently compile computer software.

in the classroom teaching of all subjects, computers will become an effective teaching aid. For example, in the teaching of literature, the script or story is explained by the procedure of "classics", accompanied by a pause. At this time, a variety of options are displayed on the screen to test whether the students understand the content correctly. If you choose correctly, the story will continue, otherwise there will be a buzz and you will be asked to answer again. For some chemical reaction experiments that take a long time, some principles and concepts that are difficult to understand and some natural phenomena that are difficult to observe can be displayed in a shorter time and intuitive form through computer simulation. Computer is a good helper to train students' experimental ability. It can be matched with a variety of instruments to process data quickly and accurately, and help students complete experiments and draw correct conclusions.

At home after school, the home computer "TV learning machine" will guide students to review their lessons. This kind of machine can work according to the program written by the teacher. As long as the floppy disk is inserted into the machine, it will ask questions to test the students according to what the teacher said in class today. If the student answers correctly, the learning machine will automatically ask the second question; If the answer is wrong, it will ask questions again or explain what it has learned again until the students understand.

In order to expand the educational function of computers, computers in schools and families can be connected with computers in teaching centers to form a nationwide computer teaching network, and various cultural classes can be taught, counseled and consulted. By then, students can learn all kinds of knowledge by sitting at home.

Electronic blackboard for self-teaching without teachers

In the future, when teachers are on leave or lack of teachers, electronic blackboard can act as a correspondent, "relay" teachers' lectures and guide students to complete their learning tasks.

The electronic blackboard is similar in appearance to the ordinary blackboard, but it is made of special pressure-sensitive materials. When the teacher writes the teaching content on the electronic blackboard with chalk, the blackboard can not only show the handwriting to the students in the classroom, but also convert the chalk handwriting into an electrical signal, and then transmit it through the telephone line. So people also call it "pressure-sensitive electronic blackboard".

With the help of the electronic blackboard, a teacher can give lectures to several classes at the same time, and even students in other schools can hear the teacher's lectures. The electronic blackboard can convert the chalk handwriting written by the lecturer on the blackboard into digital symbols through the image transceiver, and then send it to the TV screen of other classrooms or another school. The teacher's voice can be transmitted by telephone through the microphone in the machine. If it is closed-circuit television, it can also show the figure of the teacher. In this way, if a teacher is absent, there is no need to worry about no one attending class.

the electronic blackboard has other advantages. People can receive the digital symbols "transmitted" from the blackboard at the remote control station and convert them into images for teaching communication or evaluation of teaching effect. In addition, a copying machine can be connected to the receiving end to record the images on the TV screen and the sounds in the microphone for students to review and parents' family counseling.

talking audio-visual books and periodicals

In the near future, a kind of vivid books and newspapers will be popularized, and people will call it audio-visual books or electronic books and periodicals.

audio-visual books and periodicals are mainly composed of two parts. One is a device for storing information, usually a disk or optical disk, which stores all the words, illustrations and sounds of books and periodicals, with a lot of content and a small volume; The second is an electronic reader smaller than ordinary magazines, which manipulates, displays and disseminates words, images and sounds. At the front end of the e-reader, there is a flat screen the size of a page, and its back is illuminated. There are speakers at the left and right sides of the screen and buttons at the bottom. By pressing different buttons, you can select the contents of books and periodicals, and display and read them out on the reader.

the content of audio-visual books depends on the capacity of the CD. A disc the size of a dish can store the contents of People's Daily for ten years. With the development of electronic technology, audio-visual books and periodicals can store the words, images and sounds of an encyclopedia, and people can also change the contents of books and periodicals by changing the recorded cards or discs. Another possibility is that people can contact friends far away, borrow electronic books and periodicals, and listen or read them on your reader as long as they attach a suitable device to books and periodicals.

At the beginning of p>1984, an American publishing company developed the first talking Encyclopedia of American Social Sciences. When readers read about Beethoven's life, they could hear his symphonies. Looking at the photos of Martin Luther King, you can hear his generous speech. This kind of electronic books and periodicals also provides convenience for blind readers. As long as they are familiar with the buttons on the reader, they can enjoy the wonderful contents of a book and periodicals that he can't see.

Audio-visual books and periodicals have the characteristics of spreading knowledge more accurately, vividly and deeply than printed books and periodicals, but it is impossible to completely replace printed books and periodicals. Because it can't be carried around like printed books and periodicals, it can't be taken to trains and cars to watch, and it will make people feel hard to read the words and images on the screen for a long time.

Library in Pocket

In the future, all the books and materials collected by Beijing Library can be recorded on a piece of film with a width of 1 cm. In this way, you can take some of the biggest "libraries" in the world with you in your pocket.

The film containing a large library is a holographic film. Holographic film is shot by a novel holographic technology. Through a special device, it focuses a page of 135 film-sized data into one point with a laser beam, and shoots it on holographic film through the interference of light. Therefore, a tiny light spot on the photographed dry plate contains a page of 16-inch data. This material can display 15 Chinese characters. At present, the holographic mass storage developed in China has a diameter of 1 mm, and a dry plate the size of a page can record more than 16, light spots, which is equivalent to storing more than 1 books with 3 pages, thus realizing the miniaturization of books and materials.

this miniature book is also very simple to read. As long as a laser beam identical to that in storage is accurately directed at the light spot of a certain data to be displayed, the light wave diffracted by the hologram point can accurately reproduce the data content on the screen made of ground glass. If you need to reduce or enlarge the picture, just move the front and back distance of the ground glass.

In practical use, there is an electronic reader, which has several holographic plates inserted and has millions of pages of data. When reading, as long as you press the index address button at the bottom of the display screen, the integrated control circuit can quickly select a dry version and take out the spot to be searched for you to browse. If you need to know the contents of a paper or a book in detail, you can press the control button and the copying device will copy the displayed page.

In the future, this miniature "library" will be smaller than a button, and it can be installed in a microcomputer for carrying around or form a computer book network. People can read the materials of any library on the network as long as they carry a terminal device with them, which is very convenient.
