Chapter 1. POTENTIAL OF ICT

1. Select correct alternative from the following.

i   ICT stands for Information and Communication technology.

ii  Internet is the information Highway.

iii The term knowledge society generally refers to a society where knowledge is the primary production resources.

2. State true or false.

i  ICT is a new technology for communication.

Ans -> False

ii Advanced skill includes expert thinking, which may lack rule based solution.

Ans -> True

iii  International network of networks is called browser.

Ans -> True

iv Video conference is used for single person at a time.

Ans -> False

3. Answer in brief.

i  Define Information Communication Technology.

Ans -> ICT is a combination of technologies that allow as to manage and communicate information effectively. The six elements of ICT are  (1) People, (2) Information,(3) Communication, (4) Procedure, (5) Hardware, (6) Software.

                The term Information and Communication Technologies  refers forms of technology that are used to transmit, process, store,  create, display, share or exchange information by electronic means. ICT include such technologies as radio, television, video, DVD, telephone, satellite systems and computer and hardware and software.

ii Define information highway.

Ans -> The information superhighway is an ever-growing global information and communication network of fibre optic cables that links computer and other communication networks, such as telephone networks, cable television networks and satellite communication networks.

       Information as well as audio and video services are available through the Internet.All types of information are digitalised and packetted before  transmission over the Internet, each packet contains packet routing and assembly instructions called protocols. The protocols give the destination,return address and how the receiving computer can rearrange packets back in to the original information.

iii Define Knowledge society.

Ans -> The term knowledge society generally refers to a society where knowledge is the primary production resource instead of capital and labour.

      Knowledge has become a major source of productivity. Globalisation and new world economy demanding knowledge-based economies.  A knowledge society create, share and uses knowledge for the prosperity and well-being of its people. In society, the knowledge society brings greater access to information.  Individuals there fore have more opportunities to participate in and influence the development of their societies. 

iv Write two roles of educator to promote literacy.

Ans ->  ICT enables an educational environment where the online world is integrated with the physical campus.  The students should have the skills to use ICT in education.  Teachers can act as a facilitator.

    Proper planning and execution is necessary to ensure that future generation is equipped with the skills to derive maximum benefit from the use of ICT.

    Students should experience computer aided teaching.  Students should also have the opportunity to use various software's in practical classes and assignment for effective learning.

4. Answer the following questions.

i  Explain the scope of ICT

Ans ->  Education is a life long activity ICT enables flexible learning environment.  The advantages of ICT in education are as follows.

*  The world wide web (WWW) is a vast collection of knowledge, Even a villager can search WWW for the latest information, reference books, teaching techniques, information about curriculum and text books, etc are readily available on the Internet.

*  Open universities, distance education resources through ICT are the new avenues for employed people to acquire knowledge. ICT enables learning anywhere anytime with an economic manner.

*  Television is one of the best communication mediums to educate students, farmers etc. TV showing video clops of  difficult experiments or advanced surgical methods, innovative agricultural procedures etc.

*  Educational Cd's, DVDs help students from kindergarten (KG) to postgraduate (PG)

*  LCD projectors can be used for computer aided teaching and interactive learning in the classroom.

*  Online examinations and tests will solve problems,such as availability of personnel, human mistakes etc.

ii  Explain knowledge society for ICT, education and development.

Ans -> Knowledge has replaced industrial organisation and production as the major source of productivity .  Knowledge society where knowledge is the primary production resource instead of capital and labour.  Globalisation and the changing world economy are driving a transition to knowledge based economic growths.

     Education is very important in the knowledge society.  It is seen as (i) a source of basic skills, (ii) foundation for development of new knowledge and innovation,and (iii)  A mechanism for socio-economic development.

     ICT is the enabler for both innovation and education-with our which a knowledge society cannot be realised, supported or further developed.

iii  What are challenging skill requirements.

Ans ->  Because of computerisation and globalisation,  the labour force need  to be higher skilled and information literate.  Thus education systems  needs to emphasise developing the following key skills.

1.  Basic skills :  Teaching advanced skills must be preceded by a strong foundation of basic reading writing and mathematics.

(a)  Reading - As computer technology and increased global competition accelerate the rate of economic change the need for reading has increased correspondingly.

(b)  Writing effective and repaid information exchange through documentation or emails requires the ability to write  clearly and persuasively.

(c) Mathematics computers have transformed concrete processes in to numerical abstractions.  The use of these abstract models now pervades many jobs and has turned many people into mathematics consumers.

2.  Advanced skills :  These involve tasks that cannot be accomplished by following  a set of rules and, therefore, cannot be computerised.

(a)  Expert thinking involves information processing to solve problems for which there are no rule-based solution and must be solved through  understanding of the underlying relation ships.

(b)  The skill of complex communication involves social interactions to acquire information, explaining and making effective arguments.

iv Explain the transformative impact of ICT.

Ans-> ICTs are able to reach students in any place at any time. This has a potential to promote revolutionary changes in the traditional educational model.

* 1.With ICTs, we can reduce classroom time by engaging students in educational activities at home, in a library, or  in any other unconventional setting.

* 2. ICT can provide courses that small rural or urban schools to teach mathematics ,science and foreign languages.

* 3. One teacher can manage several schools at a time through on line instruction or TV.

* 4. With the help of ICT , experts can teach the on line courses.

* 5. ICT can make multi-grade schools viable in areas with low population density.Students can interact with multimedia computer software.
