DEVICE FOR TRAINING IN WRITING LETTERS, LETTER COMBINATIONS, AND DIGITS

摘要

The present invention relates to technical aids of education and can be used for training in writing of the first class pupils of general education schools. The proposed device for training in writing contains a plate with letters, letter combinations, and digits, a pen simulator, and an eraser simulator. For forming letter and digit lines, small balls are used that constitute magnetic dipoles. One half of the surface of each ball has color that coincides with the color of the plate and is magnetized according to the magnetization of permanent magnet in the lower part of the pen simulator. The second half has color that differs from the color of the plate and is magnetized oppositely to the magnetization of the first half. The balls are placed in pits at the plate surface that are filled with liquid. The eraser simulator is made of magnetic material and magnetized identically to the magnetization of the ball surface with color that differs from the color of the plate. The proposed device provides a possibility to enhance the training efficiency and improve the memorization of hand movements by a pupil.
