2. Presentation did not confuse students.
3. Readability and difficulty were at an appropriate level for students.
4. Graphic fulfilled important purpose.
5. Appropriate feedback for correct answers.
6. Feedback reinforced more for correct than for incorrect responses.
7. High degree of interactivity. 8. High degree of user control.
9. Comprehensive teaching sequences and instruction was self- contained and stand alone.
10. Good documentation available on how program.
To measure the soundness of the content used in the CAI package the following criteria may be used:
1. The content was reliable. 2. Correct used of grammar.
3. Current and error-free information.
4. Concepts and vocabulary relevant to students‘ abilities. 5. Information relevant to curriculum.
6. Information of sufficient scope and depth. 7. Logical progression of sub-topics.
8. Content matches required curriculum objectives.
9. The content was structured in clear and understandable manner.
10. The structure allowed students to move around freely in different units.
To measure the Technical soundness of the CAI package the following criteria may be used:
1. Program loaded consistently without error.
2. Program did not halt regardless of the response from the students.
3. Online links worked as indicated. 4. Animations worked as indicated.
4C.8 SUMMARY
Teaching is generally considered as an activity which is designed and performed for multiple objectives in terms of changes in pupil behaviour. Pupils on the other hand have multidimensional personalities having different styles. The common implication of both these facts is that the teacher should use different strategies of teaching which match the objectives of teaching on one hand and pupils learning styles and personality dimensions on the others. CAI package have revolutionized the whole teaching and learning process by adapting to individual learning needs.

5.1 INTRODUCTION
Information and Communication Technology (or ICT) has come a long way since its inception which is parallel to the evolution of human kind. The need to communicate or share own viewpoints, feelings gave birth to this technology in the form of script, gestures and body movement. As man started his journey towards modernization ICT too became enriched with the newer technologies ranging from print media, simple audio, video gadgets to the latest one, that is computer technology. This advanced Technology is fast becoming an integral and inevitable part of every aspect of life. A very important and core element of Computer technology is INTERNET.
Internet is a system connecting computers around the world using TCP/IP, which stands for Transmission Control Protocol/Internet Protocol, a set of standards for transmitting and receiving digital data.
The Internet consists primarily of the collection of billions of interconnected web pages that are transferred using HTTP (Hypertext Transfer Protocol), and is collectively known as the World Wide Web. The Internet also uses FTP (File Transfer Protocol) to transfer files, and SMTP (Simple Mail Transfer Protocol) to transfer e-mail.1
1. http://www.apdip.net/publications/iespprimers/eprimer-edu.pdf Imagine you are connected to the Internet and are on the Google Home page. You want to find out the information on the topic of your choice. You would type the name at the Search box and you find thousands of web addresses appearing on your monitor screen. This becomes possible due to HTTP. These are standard set of rules universally applied for sharing information.
For Example Whenever you want to surf a particular site you need to type at the URL bar beginning with. http://www, i.e.
http://www.apdip.net where http://www.are standard rules and remaining part is a specific desired type of information.
The Internet thus is the interconnected network of the web pages which could be surfed through different search engines like, Google, Yahoo, Hotmail etc. They are called Search Engines.
Historical Background of the INTERNET
The US department of Defence developed the first version of Internet during 1970s to allow quick communication among researchers working on the department projects in about 30 locations. The department also saw as a way to continue communications among these important defence sites in the event of a worldwide catastrophe such as nuclear attack. Since these projects were funded by the department‘s Advanced Research Projects Agency(ARPA), the Network was originally called ARPAnet.
In the 1980‘s just as Desktop computers were becoming common, the National Science Foundation funded a high speed connection among University centres based on the ARPAnet structure. By connecting their individual network, Universities could communicate and exchange information in the same way. However, these new connections had an additional, unexpected benefit. A person accessing a university network from home or school could also get access to any site connected to that network. This is how the Internet was born. It is also called as information superhighway
or cyberspace.
Internet in education:
There are many uses of Internet in Education which can be as follows:
Instructional materials can be made available to students online. E.G. Written material, Various presentations, assignments can be given to students. Even the instructions too can be conveyed to students via internet.
The learner gets the scope of learning desired course anywhere anytime thereby making learning more flexible, interesting and meaningful.
Internet also helps in removing the age restrictions. The learner ranging from young lots to the adults can enhance their learning as per their needs.
Online conferences can be organised online for the learners from distant places having common interest. The learning that requires prior preparations also can be provided through internet with the loads of instructional material available online.
Research work also can be carried out by both the learners as well as teachers with the help of e-library, topical data bases on World Wide Web.
Individualised as well as group methods can be applied online with the help od varied internet tools like e-mail, discussion forum, Chat rooms, WWW etc. which are discussed in detail in the next segment of this unit.
Thus the Internet is a revolution in the field of technology that has changed the entire pattern of education and has provided a storehouse of knowledge for the learners to explore for enriching learning experience.
