A single group Pre-test and Post-test design was employed for the study. 20 students who were randomly selected from Standard VIII of the New Era Senior Secondary School, Baroda. Pre-test, Post-test and opinionative were used for the study. The data was analyzed through t test, percentage scores and correlation. There was found a significant gain in terms of students achievement through Information Technology enabled instructional package. It helped the students to learn kinds of sentences namely, interrogative, assertive, affirmative, negative, imperative, orders or commands, and exclamatory. The students and teachers were found to have favorable opinion towards the developed instructional package. First one is of Ananthakrishnan (2000) who has conducted on Effective Use of Multimedia for Teaching Languages to Adult Illiterates: A Case Study in Tamil describes the approach of a successful computer based functional literacy programme for imparting reading skills in Tamil to illiterates. The key success factor was the effectiveness of multimedia technology, its compelling and exciting interfaces and interaction. Similarly Shital Yadav (2000) conducted a Study on The effectiveness of the computer software for students of I standard. The study reveals a

53 significant gain in terms of mean achievement on the software on Alphabets and Animals. Most of the students were found to have positive reactions towards the software. Teachers welcomed the media integrated approach towards learning. b) Studies conducted on e-learning Out of 62 studies 24 were conducted on e-learning the brief summary of the study are given below. Amuthavalli & Zuneetha Bai (2008) in their paper on The Problems of B.Ed Trainees in Learning Educational Technology discussed the problems of B.Ed Trainees in learning Educational Technology. The sample for the study consisted of 400 college student teachers selected randomly from Andhra and Rayalaseema colleges. The data were collected using checklist cum rating questionnaire to elicit the opinion of the student teachers about their difficulty and intensity level of the problems in learning educational technology. The checklist contains 45 statements related to learning of educational technology by the student teachers. It can be inferred also that the variables namely sex and management had no impact on the intensity level of problems related to learning Educational Technology. Annie Marie Merlene (2008) conducted a study on Impact of ICT Based Teaching-Learning Environment and the Changing Role of Teachers addressed the impact of ICT, in the teaching-learning environment, and the changing role of teachers in the present scenario. In an ICT based Learning environment, the relations between the teachers and pupils tend to change, with

54 the teacher losing the monopoly of authority and not being in control of what happens in a connected classroom. Most of the teachers of today happen to belong to the Television generation and being Television shaped learners, will have to learn new methods of ICT, to keep pace and to be at par with the present day Internet-shaped, Neo-Millennial Learners. Devananthan (2008) conducted study on Integration of ICT into Teacher Education highlighted the need for ICT training for teacher educators. The full benefit of technology in the education process is realized only by enhancing the ICT skills of teacher educators and students, ensuring adequate system support and providing the funds necessary to build a new academic framework around the new resource. ICT helps in the professional development to teaching and learning and individuals involve in the programs of teacher education. It can be infused in the learning process for the acquisition of knowledge and skill. The teacher educators should be motivated to undergo training in the use of ICT equipments. Jahitha Begum (2008) conducted a study on ICT-A Tool for Quality Enhancement in Education observed that Teacher s role has been changed to observing, intervening, monitoring and supporting learning. Technology in its various forms like e-mail, tele-mentoring, online education, teleconferences, and streaming video have enhanced the quality of teaching learning process Knowledge Building Communities when attempting to create new knowledge, make advances in textual, graphical and computer literacy and develop depth of inquiry and a host of mature knowledge processes.

No significant difference was found in the achievement of boys and girls of rural areas in the Post-test on atomic structure and chemical bonding. 135 boys out of 180 and 64 girls out of 99 wanted to continue the study with the PLM on both the topics. The weakness of individual students were diagnosed and removed when branched frames on both the topics were administered. Kumaran & Deivaraju (2001) conducted a study of the Attitude of Teachers towards Computers. It was concluded that in general teachers had more favourable computer attitude. The gender of the teachers had significant influence on their attitude towards computers i.e., the male teachers had more favourable attitude towards computers. Sanjna (2001) conducted a comparative study of the effectiveness of CAI and CMI on Pupil s achievement in Science, their self concept and study involvement. Both CAI and CMI were found to be contributing significantly towards the achievement of pupils in science, in developing their self concept and in increasing their study involvement. Sivakumar (2001) in his study entitled A Study of Computer Awareness among Student Teachers of Colleges of Education in Tamil Nadu

68 reported that there was no adequate computer awareness among the students teachers of Colleges of Education in Tamil Nadu. Balasubramanian (2000) conducted a study on Computer Based Instruction in Developing Reading Skills among Primary School Children. He compared the effects of different technologies and found that the reading skills and English pronunciation has improved considerably with computer based instruction. Panda, et. al. (2000) conducted a study on the Effect of computer Assisted learning in achieving Higher cognitive skills. The study is to determine the degree of attainment of cognitive skill through computer Assisted learning computer to traditional approach to teaching. The findings of the study reveal that Computer Assisted Learning resulted in greater achievements in all hierarchies of cognitive columns. Shah, et. al. (2000) conducted a study on Teachers Attitude towards Computer Assisted Instruction and Computer Education in relation to sex, organisation and experience. This study focused on the attitude of the Higher Secondary School teachers towards Computer-Assisted Instruction and Computer Education. The major findings were the Teachers had a great liking for the computer as a subject as well as a medium of instruction. The female teachers had more positive attitude towards computer education when compared with the male teachers.

69 2.2.2. Studies conducted Abroad The investigator has identified 48 Studies which were conducted Abroad. Out of these, the studies conducted in Multimedia, e-learning and CAI were 7, 34 and 7 respectively. The brief summary of the studies are presented below. a) Studies conducted on Multimedia Mckinnon & Sinclair (2007) studied the students attitude towards the use of technology. He found out the attribute of students towards technology. The major finding of the study is that students showed positive attitude towards the technology tools. NGU, B. H. & Soubakeavathi, R. (2006) conducted a study on Evaluation of CALL software on the learning of English prepositions. This study evaluates the effectiveness of a CALL lesson (Computer Assisted Language Learning) when compared with a conventional lesson in assisting students to learn English prepositions in a Malaysian school. The study indicates that students who received conventional teaching performed better than those who went through the CALL lesson. It was observed that there was greater improvement from a Pre-test to Post-test for the conventional group rather than the CALL group. It also shows the conventional group with the latter exerting more mental effort and achieving a lower transfer performance than the former. The authors/ researchers suggest that to facilitate the transfer of learning, the design of an educational software package needs to minimize the mental effort required to handle the medium and the content.

70 Whitely Michael (2006) conducted study in the impact of multimedia learning on students perceptions of cross-community initiatives, future orientation regarding peace and social distance between groups (Northern Ireland). The Instructional Multimedia Presentations and Cooperative Technology (IMPACT) conference was created, in part, to challenge these findings through the monitoring of cognition, future orientation, and social distance of the attending students. A total of 522 fifth grade students participated in the study from the Northeastern Board of Education in Northern Ireland. The study utilized the Solomon four group research designs. Schools participating in this research were selected through a stratified random sampling procedure and included 12 Catholic and Protestant schools. The study found significant effects of the IMPACT conference on participants in the areas of cross-community cognition and future orientation. No significant effect was found in the factor of social distance. Parcel (2005) conducted a study to find the effectiveness of the use of multimedia in probing the answers from the students. The research administered the online tutorial to 147 fifth grade students at one of the there different elementary schools. The result of the study shows the use of multimedia in publishing questions was effective as there was a Significant different between the Experimental and the Control group in answering to the probed questions. Wegeriff, R. (2004) conducted a study on the role of educational software as a support for teaching and learning conversations. The main objective of this study is to examine the dual nature of computers as machines

71 (objects) which can be made to act as if they were people (subjects) which allows them to play a potentially distinctive and valuable role within educational conversations. This role is to resource and at the same time, to frame and direct, learning conversations amongst small groups of children in English schools. One hundred and nineteen children aged between nine and ten participated in the study. The evaluation included video-recording, transcript analysis and a matching Control group who covered the same areas of the curriculum without the intervention. The qualitative findings show learning occurring in the talk of the children working around computers and the quantitative findings suggest that this approach can produce significant learning gains within the normal curriculum. The evidence presented in this study shows that a combination of pedagogy and software design can exploit the ambivalent nature of computers to make them serve as both interactive agents, or tutors, and as passive learning environments within the one educational exchange. Asan, A. (2003) conducted a study on School experience course with multimedia in teacher education. This study describes an interactive and selfpaced multimedia tutorial program that provides pre-service teachers with a complete range of school system and teaching strategies. It evaluates the impact of the program on pre-service teachers learning experiences. Two methods of information delivery were investigated: traditional learning and multimedia. The results show that using the multimedia tutorial leads to a positive difference in the school experience course over participants in traditional lecturing. Pre-service teachers who participated in the multimedia

72 group responded positively to a multimedia approach. This study concludes that using multimedia in teacher education enriches pre-service teachers learning and provides them with an opportunity to view and critique various teaching methods and classroom activities collectively. Among the 7 studies identified in this area, Poulin (2000) has made a study on the Attitude of both the teachers and the students towards learning through multimedia. The investigator conducted the study through questionnaire, interviews and observation and found that both teachers and the students had positive attitude towards learning through multimedia. Studies conducted on e-learning Out of identified 48 studies conducted Abroad, 34 were conducted on e- learning. The brief summary of the studies are given below. Littlejohn, et. al. (2008) explained that the widespread availability of digital learning resources in a variety of media formats offers the possibility to make a profound difference in education. This potential has not been fully realized for range of interrelated reasons. In this paper the key characteristics of learning resources were studied that have proved effective in changing learning and teaching, and then it was related to existing frameworks for understanding resources. The researcher outlined the relationships between resources, their users, and the way they are used and explored issues that influence practitioners in choosing a particular resource. The study is based on a review of resources for e-learning and chemistry in post-compulsory education, undertaken for the UK Joint Information Systems Committees (JISC), as part

73 of a wider study examining "The Effectiveness of Resources, Tools and Support Services used by Tutors in Designing and Delivering E-Learning Activities." Maria, I.H.R. (2008) conducted a study on the Use of ICT by ELT students in a Mexican University. The results showed that in general the participants used ICT tools for academic purposes although some training may be necessary. In terms of frequency of use, some differences were observed among some tool types. Also the participants reported using several functions offered by every single ICT tool. Van Rosmalen, et. al. (2008) explained that the introduction of e- Learning often leads to an increase in the time staff spends on tutoring. To alleviate the workload of staff tutors, a model was developed for organizing and supporting learner-related interactions in e-learning systems. It makes use of the knowledge and experience of peers and builds on the assumption those (lifelong) learners, when instructed and assisted carefully, should be able to assist each other. The model operates at two levels. At level 1, prospective peer tutors are identified, based on a combination of workload and competency indicators. At level 2, the thus identified prospective peer tutors become the actual tutors; this is performed by empowering them with tools and guidelines for the task at hand. The article will situate the model in networks for lifelong learning. For one kind of interactions, answering content-related questions, we will review a set of existing approaches and emerging technologies and describe our model. Finally, description and discussion of the results of a
