Among modern means of teaching an important place during the process of acquiring new knowledge to deal with technical and audio-visual training aids.
What are the advantages of the use of technical means
At present, the technical training presented devices created by the computer.With their appearance, it became possible to modeling all phenomena and processes.An important advantage of these devices is the ability to simultaneously conduct training more students.With TCO teacher can provide students with the necessary educational information to improve the process of perception and memorizing of acquired knowledge, their application in practice, to monitor the effectiveness of teaching.Because the training facilities are equipped with special units, allowing to store and reproduce information support special programs, can lead the cognitive activity of students and to control it.
Types and purpose TCO
To date, the following technical and audio-visual training aids, by which made possible the transmission of information: multimedia projectors, overhead projectors, epi-projectors, overhead projector, projectors, film projectors, multimedia boards, audio, tape recorders, televisions,, VCRs, computer.These technical device capable of converting the information recorded on one of the media types, in a form suitable for perception.
transmission of information, programmed learning, knowledge control, the solution of problems of training and exercises - such functions are performed by means of training in school.TCO can be a general-purpose and specialized.The latter include the complexes for the study of biology, mathematics, physics and other subjects, language laboratories, designed for better assimilation of foreign languages.
Using TCO during training and especially
Before applying technical training, students should be familiar with their work.During the first lesson you need to keep track of how students perceive new information, whether it is stored, giving them cognitive tasks, monitor their progress.Only then can use during lessons hardware becomes effective.Otherwise, students will focus their attention on minor points, and educational information will remain undigested.
From how often the teacher uses a technical training school, depends the efficiency and effectiveness of the educational process.If this is rarely done, the lessons with TCO turn into an extraordinary event, will excite much emotion in children.This, in turn, would interfere with the absorption of the studied material.In the case of the frequent use of TSO students may lose interest in the work.Therefore, we must necessarily take into account the peculiarities of psychology and the age of the pupils, a subject on which these funds will be applied.
Stages lesson also affect how effective is the use of TCO.Use more than twenty minutes at a time during the lesson, teaching aids inappropriate.Students already tired, learning new information will not bring the desired positive results.
can use the TSO at the beginning of the lesson.This will reduce the period of preparation for the perception of new material.In order to keep a steady focus on children throughout the 45 minutes, you should refer to the use of technical means 15 - 20, 30 - 35 minutes after the start of the lesson.It is known that during the lesson the students from time to time changes visual and auditory perception, there is fatigue, decreased concentration.Proper and reasonable alternation of different methods of work in the classroom with the use of technical means to help avoid these effects.Intense mental work must give way to emotional discharge, the weakening of the visual perception as well as hearing.
