ABOUT THE COURSE

The growth of knowledge-based societies presents great opportunitiesand challenges for the social and economic health of all countries.Science and Technologies contribute remarkably for this exponentialgrowth. Among these, Electronics is a very vast field, embracing almostall walks of human endeavours. Rapid advancements in Electronics andCommunication Technology have already had a profound impact onlife in the 21st century.

The development in semiconductor technology made it possible tointegrate a large number of devices in a small silicon chip, known asintegrated circuit. Today the computers, made using these powerfulchips, have tremendous capabilities, which can be used for almost allapplications- business, scientific, engineering, defence, etc. The majorareas of applications of electronics and communication areinstrumentations, general communications, medical electronics,computers, wireless communications, automobiles, entertainments, etc.

With the advent of Internet and E-commerce, new ways of doingbusiness have emerged. In the next few years, it will be possible to builda virtual company, using the most appropriate people. Furthertechnological advancements in these areas have been predicted, to makethose kinds of gadgets essential in the high-tech future.

Twentieth century science fiction is turning into twenty first century fact.The future looks exciting, as the change is accelerating at rapid pace.Thus the relevance of electronics and communication technology opensa large number of opportunities in the related fields.

The electronics and communication technology course aims to developin students the skills, attitudes and knowledge to cater to the emergingneeds of Technicians in this field. It also provides opportunities to theaspirants for higher studies in diploma and/or professional/vocationaldegree.

JOB ROLES

SUBJECT APPROACH

Vocational Higher Secondary Course in ECT is designed to achieve theskills required for various blue collar jobs falling under four distinctareas of Electronics industry. In an industrial scenario such asElectronics and communication, where technology changes faster thanflash of light, it is not as that easy to equip an incumbent with the latesttechnical know-how. But if he is well trained to acquire the basics andprepared to update and apply the knowledge to newer situations, it willbe easier for him to get adopted to the new atmosphere. To be verysimple, this is the attitude and approach accepted and followedthroughout the treatment of the subject.

Page - 55

VHSE Curriculum

The course is expected to cover the skills related to four most relevantfields of modern electronics namely Basic Electronics and SoundEngineering, digital Electronics Computer hardware and networking,Microcontroller and Robotics and Wireless and fibre opticcommunication and Mobile Technology. Needless to say these are theareas which bring about rapid changes both in our daily life and withintheir own technology itself. Being aware of the complexities of the /topics, maximum care is observed to restrict the depth of treatment notto go above the limit that can be conceived by a learner at highersecondary level. Unwanted derivations ambiguity theoreticalexplorations and surplus of irrelevant data are strictly avoided. At thesame time theoretical back up and support is always provided whenand where demanded. The treatment of the subject is totally based onvarious activities intended to create the interest in learners and ensuretheir active involvement "Learning through Doing" motto is tried to befollowed to the extent possible. Most of the activities are so planned asto carry out in groups since that will help to develop interactive learningand peer sharing.

The scope and nature of the subject does not allow to limit the activitieswithin the four walls of a class room. Some of the activities are definitelytargeted to let loose the imagination of the learners and acquaint themwith the real atmosphere they are to experience during and after thecourse. While most of the activities can be performed within the classroom and laboratory with the supportive infrastructure, a few of themare to be arranged in a neighbouring work site or establishment throughfield visit or on the job training.

Another important factor considered while approaching the subject wasthe scope for vertical mobility. As stated earlier the treatment of thesubject is purposefully restricted to basic level. At least a few of thelearners may not be contented with this and tries to climb further. Forsuch aspirants to fulfil their dreams there is enormous scopepossibilities. A part from the conventional graduate and diploma levelcourses many of the reputed institutions and universities such asIGNOU are conducting specialised diploma and degree courses in allthe four modules included here. These courses offer better placementand professional growth than any other orthodox stream.

Last but not least, the social and ethical values tried to be incorporatedmust be mentioned. The course is so designed as to come within theframes in side education, providing equal chance and scope fordifferently able children. Majority of the suggested activity can be soplanned as to include these children also. Also most of them do notwarrant a much hard work or physical strain. Most of the targeted jobrolls are also can intake persons with differential abilities without any

sacrifices on result. The more important social commitment and otherresponsibilities are never forgotten in our approach to the subject.Activities are so planned to encourage interaction among learners,improve team work, trust and care each other and fight with single mindto attain an outcome.

The purpose of any stream of education is not simply to dump piles ofknowledge to one's mind, but to develop necessary skills andawareness within him to enable him lead a successful life. To lead asuccessful social and personal life it is essential to cultivate the varioussoft skills or life skills such as sharing, caring, helping etc. within him.The activities presented here are not merely targeted to attain theoutcome only but carefully planned to develop these soft skills. In shortthe course put forward a single motto for our dear learners" The carrieris not simply a mode of making money but a holy and jolly way ofliving a fruitful life".
