INTRODUCTION

Radios are tools for the transfer of information, concepts and ideas to both general and specific audiences.Major functions of radio is to educate, to inform and to entertain masses. Radio is the radiation of electromagnetic wavs through space. The major use of radio s to carry information. A radio communication system sends by radio

History of radio

In 1864 James Clerk Maxwell showed mathematically that electromagnetic waves could propagate through  free space. The effects of electromagnetic waves were actually observed before and after Maxwell's work by many inventors including Luigi Galvani (1791), Peter Samuel Munk (1835), Joseph Henry (1842), Samuel Alfred Varley (1852), Edwin Houston, Thomas Edison (1875) and David Hughes(1878).

Around 20th century Guglielmo Marconi, developed the first apparatus for long distance radio comunication. On 23rd december 1900, Reginald A.Fessenden became the first person to send audio (wireless telephony) by means of electromagnetic waves, successfully transmitting over a distance of about 2.6kn and 6 years later on christmas eve 1906 he became the first person to make a public radio broadcast.

Information such as sound is converted into an electromagnetic pulse signal, which is then sent as an electromagnetic radio wave from a transmitter.A reciever intercepts the radio wave and extracts the information-bearing electronic signal, which is converted back using another transducer such as speaker.

uses of radio in education

Radio can spread information to greater group of people and save time , energy, money and manpower in an effective way. Radio is cheap and simple to operate. It helps both developed and developing countries.

Education in India

FOR TEACHERS

AIR arranges separate programmes for teachers. Agencies like CIET, NCERT,SIET,SCERT, teacher training department are involved. Methodology for teaching, child psychology etc are also covered.the objective of the programmes are to familiarize curriculum changes, technology advancements and contents necessary for teaching staff.

MERITS AND DEMERITS

Important happenings, election results, inventions etc can be discussed in classrooms.It also provides student participation in various programmes like quizzes, talk shows.It has wide coverage and is cost effective.

Adequate attention from all listeners cannot be expected, development of material is time consuming and playback,recording equipments are costly.
