What is IT ?
• Information technology (IT), as defined by the Information Technology Association of America (ITAA), is "the study, design, development, implementation, support or management of computer-based information systems, particularly software applications and computer hardware." • IT deals with the use of electronic computers and computer software to convert, store,
protect, process, transmit, and securely retrieve information .
• Now a days Information Technology (IT) is a general term that describes any technology that helps to produce, manipulate, store, communicate, and/or disseminate information. Presumably, when speaking of Information Technology (IT) as a whole, it is noted that the use of computers and information are associated.
Using IT in education sector
• Developing a wide network using concepts like ‘Internet Communication Technology’, ‘Education Collaboration Network’ • Virtual classroom concept • Development of easily understandable models and audio-visual content • Using networking and applications for better and efficient use of resources and better management
• Increasing the reach of quality education and improvement in distance education concept • Audio-Visual learning experience • Better co-ordination among education institutes and teachers leading to development and expansion of knowledge-pool • Improved special education • Easy availability of wide variety of quality educational resources • Improved teacher training

Some uncomfortable truths: Primary Education
About 10% of students in age group 7-14 are out of school
About 45% of students in Govt. Schools in age group 7-10 cannot read, 13% in age group 11-14
Increasing focus on ‘what is thought at school’ rather than on ‘are children in school’
Effective delivery of education is key
Pratham’s survey About 60% of students in Govt. Schools in age group 11-14 cannot write, 25% in age group 11-14 can’t read
75% of Govt. School students between ages 7-10 cannot do simple arithmetic
Quality and quantity of teachers, education material, resources are very low
Evidence shows that Computer Assisted Learning has improved learning
• Greycells 18 Media, a JV between ‘TV18’ and education service company ‘educomp’ launched a 24hr. channel ‘Topper TV ’ , for senior school students. • The channel has faculty from IITS, IIMS and foreign university. It is broadcasted using DTH Services. Subscription of students is between 40,000-90,000 already. • Everron systems Chennai, has signed an MOU with IIM Indore for offering management programmers using the VSAT Technology.
• Srinivas Adepalli senior VP, Tata communications wants to launch educational courses for engineering and management courses through net using the help from Pune based Tata management training centre • Amity university has launched youth TV, to cater to students needs. • Virtual classrooms like ‘extramarks.com’ and ‘classroomteachers.com’ will touch 8.5 million households by 2010 as estimated remarked V.K.Arora director (electronic and system administrator head) of IGNOU.
• It is govt. initiative to connect 60,000 govt. & govt. funded senior secondary schools on internet and intranet. Though currently it is operated as a pilot project in 140 schools of 7 districts. • Program focuses: Providing ICT infrastructure Training teachers to use ICT infrastructure Providing different learning resources which include different education tools, course curriculum & other learning materials Providing course content in regional languages

Some key problem areas in Indian education system are as follows Performance: Only 6% of students continue studies up to collegiate level and most of those who continue are poor in English, Science and Maths. According to DPEP Baseline survey extent of repetition in grade I is as high as 30-40% in some states. Teacher training: Large number of teachers are under-qualified and many more need professional training. Teacher-Student ratio:
50.00% 40.00% 30.00% 20.00% 10.00% 0.00% Teachers

Quality of material: Text books are updated infrequently and contain many errors. No collaborative feedback mechanism for gathering inputs from teachers & students Data: Though there is some system in place to collect data about primary education but no such thing present for other levels. So all planning are based on performance of individual institutes which is difficult and inefficient. Lack of support materials: Teachers are not equipped with any supplementary helps and no system is in place to share resources and ideas. No standardized system of evaluation of performance. Distribution system of books are inefficient and education is totally dependent on this conventional material
Probable IT solutions
Helping teachers by enabling a collaborative development of teaching material and making it accessible to all
Improving quality enabling mass participation in developing and maintaining materials
Improving operational efficiency by collecting disaggregated data and use of information-based methods to procure and distribute materials
Tools for sharing instruction material among institutes
Probable IT solutions..contd.
Use supply chain management techniques to improve delivery of materials
Retaining content in electronic form to reduce delay
Constructing and maintaining nationwide registry of facilities and performance statistics for proper planning & management
For this steps to be taken two basic needs are as follows
1.Data collection and storage mechanism
2.Data analysis mechanism
Education Collaboration Network
Principle requirements of ECN
Capability of handling different level of IT maturity and multiple languages Highly distributed and able to capitalize on existing IT infrastructure like EDUSAT, Vidya Vahini
Based on open standard for encoding and accessing content
The basic architecture of the ECN would be a web services oriented one, based on open standards
Components that make ECN are all commercially available which enables quick and affordable implementation
Figure: A physical view of ECN
• Architecture of the system will be ‘Client-Server Architecture’ • Software will be split between computer processes called ‘client task’ and ‘server task’ • Client side will have facilities like ‘offline content access’, ‘content authoring and collaboration’ depending upon he infrastructural support • Client will be able to send and receive data from one or more server • System will be independent of any hardware and operating system limitation
• All clients together will be able to support different level of IT maturity • Range will be from high-speed connectivity and high awareness users to limited connectivity and users with rudimentary IT knowledge Servers provide back-end support for different clients
Presentation Function s Enable users to access domain-specific content, Support all client types
Basic infrastructural services that would be required by apps( System, lifecycle, workload, storage management & security)
Handle content organization, lifecycle, storage, distribution, authoring, s earch and other processes
To support the interaction between clients and servers, presentation services of the server will support following methods of communication:
Cable Network: Client services with noncomputing abilities for simple audio and video streaming
SOAP: Simple message querying and retrieval with & w/o attachments
WAP: Mobile access of information and status updates FTP:For transferring multimedia files
HTTP:Request and responses
ECN-Architecture->Some key points:
Network topology for ECN will evolve with its spread. In initial stages server nodes will have to be hosted by state/regional authorities, district educational centers or urban schools given the current economic and infrastructural condition. Initially server platforms would run on a ‘Virtualized environment’ enabling them to use storage and resources already available to ECN This also bring down the initial expenditure.
Different types of clients allow for users with a wide range of IT facilities & awareness.
Access & collaboration can be achieved using communication technologies ranging from the internet to the telephone network.
The infrastructure allows both automatic translation of content & distributed translations by multi-lingual users.
As it builds on existing IT initiatives so the developing cost is low.
Regulation is possible but not mandatory in this approach because ‘network effect’ fairly small number of individual produce high quality contents.
