Teachers of a school have come up with electronic visual aids in an effort to use every space of school for facilitating students’ study.
“Our school has dozens of visual aids on the walls of corridors. We thought that ‘interactive visual aids’ would be very helpful to developing students’ cognitive faculties,” said Kim Song Chol, principal of Jungsin Senior Middle School in Sosong District, Pyongyang.
Last year, its teachers analysed the cognitive effects of visual aids on students. The analysis showed that they were effective for freshers, but not so productive for students in the second and third years as the aids were already familiar to them.
This prompted the teachers to make visual aids which give students fresh feelings and interest and allow them to have direct communication with the aids.
They included in a visual aid the synthesis of contents of each subject of each year or the synthesis of related contents on the principle of optimization, while designing them in such a way as to change the content on a constant basis.
The other principle they adhered to in designing them was to stimulate students’ interest and get them to develop their cognitive faculties as much as possible while operating and experiencing the aids.
Thus, they devised several forms of visual aids, including the one that allows students to listen to questions, choose answers and get marks, the one with buttons that are pressed to know what the users are specially interested in, the audio-visual one and the other one that enables students to consolidate what they learnt at school through operation and experiencing like in physics.
The periodic table in the chemistry hall is seen through a TV screen.
Students press “education” or “test” button to learn about any chemical elements or test themselves as they listen to recorded materials and see images.
The contents of visual aids are changed periodically with the alteration of the contents of RAM.
“The electronic visual aids has also enabled students to recognize the usefulness of recycling by practice. Because lots of used electronics devices and elements collected by them as well as by teachers were used in making the visual aids,” said section chief Ho Yong Ho. “The utilization rate of visual aids has jumped since we displayed the electronic visual aids.”
The school’s interactive visual aids are widely being generalized through a nationwide demonstration.
