The Future of Teleteaching in Teacher Education

In the last decades there has been a drastic increase in the-learning platforms. The innovations and technological advances in the field of Information and Communication Technology (ICT) broadly enhances our vision in various field of life whether commercial, economical, social, education, banking sectors, transportation at national or international level. This paper gives an overviews about various information communication technology in the field of teacher education specially teleteaching i.e. educational which is imparted to the students through the use of various technology carried out in a asynchronous mode. A teleteaching is an online instructional technology specially being used in massive open online courses (MOOCS) for providing services such as live, recorded lectures as video streams. It also included some intelligent integration methods for enhancing student learning outcomes and experiences. Thus this paper gives a platform for improving learning experiences by collaborative learning on teleteaching platforms.

Technological advances and new training paradigms have a strong influence our society. Today technological tools, strategies and devices are being used to impart knowledge to the students. The role of computer and information communication technologies are playing significant role towards technology-based education. There are several means of communicating with the students that can be used in either ways formally, informally or non-formally. The students and teachers both use technology during classroom practices or outside the classroom activities for teaching-learning purposes. The concept of education through education technology practices is not limited just to classroom learning but one can be educated in all the respects mediated through distance education, distance working etc. Thus Teleteaching is one concept to highlight these educational changes in a wider form.
Earlier the education was limited to four-walls of a classroom. The teacher played important role in classroom teaching. The students were just the active listeners who completed the tasks assigned by the teacher well in time. The private organizations or schools had the authority for opening educational institution in early times. But today due to educational hub all around in terms of educational centres, coaching centres, DE program, correspondence education system, open learning, universities and schools have seen a new market in this area. Later on telecommunication services have been used in many educational projects such as distance education programs that are mentioned in this paper. The technologies such as data communication, satellite T.V., and interactive T.V are being used in this regard.

UNIDIRECTIONALISM TO MULTIDIRECTIONALISM
Teleteaching teaching is an instructional approach from unidirectionalism to multidirectionslism approach.
Unidirectionlism: In unidirectionalism there is only one transfer of component i.e. knowledge. The focus component is on knowledge itself. The process of imparting education as a piece of knowledge is distributed to arbitrary number of students. The knowledge transfer occurs between the teacher and the student via skill transformation followed by feedback. Thus, this type of method is based on the several decades experiences provided in schools, organizations, early group-community, church etc.

Multidirectionalism: The transfer of knowledge skills is not among only teacher and student but amongst them also. Each and every student is being included in the classroom practices where every student engaged on a common problem through different aspects either communicating or by taking the help of teacher or other students. The teacher's role is as a guide, supervisor or knowledge imparter through various skills, strategies and methods. His/her role is just to highlight the path of success or to give directions to the students with sufficient previous knowledge, initial starting points, guidance, feedback and providing right path towards going in wrong way. Thus in this way large number of students learn together in a moderate way using different strategies, methods and skills to achieve a common target point. Here, the focus is on the method of acquiring skills and presenting knowledge. There is a quite a difference between the two terms teleteaching and group work or team teaching. The term 'Teleteaching' is closely related to the distance education while the 'Group work' or 'Team Teaching' is mutually related to the cooperative teaching followed by close cooperation through the use of wireless networks and computers to bridge the virtual proximity gap.

TELECOMMUNICATION SERVICES
The etymological meaning of word telecommunication is the science and technology of the communication of messages over a distance using electric, electronic or electromagnetic impulses. Teleteaching is basically unidirectionalism to multodirectionalism model. In teleteaching the user watches educational videos and have to pass the online tests which is necessary to issue to a certificate. In addition to it students learn better i.e. 70% in contrast to just listening with around 7%. • Improves communication skills: The healthy interaction between the students and the teacher educators promotes them to expand their vision nationally or internationally. Thus, irrespective of the distance or geographical region, we can share different views, ideas and concepts among themselves. • Self-assessment and evaluation: The students can watch educational videos, clips or lectures delivered by the teacher according to their own pace and individual differences. One can watch as many times according his/her capabilities and thus helps in self-assessment of one's academic achievements through feedback, assessment or comments. • Access anytime, anywhere: The technology has widen its wings so long that it is possible to connect with anyone anywhere provided one must be on-line or using communication networks synchronously or asynchronously.

Problems hindering Teleteaching
Besides advantages teleteaching may have some drawbacks by incorporating teamteaching in it.
• Time constraint: The shared content sometimes allows multiple intersection or interlocking contents. The lecture, content, or images are to be discussed timely as sometimes there may be gap in the discussions. The delay in teacher's lecture contribution would not promote active individual feedback and assessment. • Presentation context changes: Since the multiple access to content sometimes changes the theme, content, or idea of the concept by experts, educationists etc. Thus, it would not be able to judge or to find out the changes content, theme or idea. Or in some cases the same pages are uploaded to the web, or many new groups have submitted to the web or students might have added comments every time login to the portal. Thus, the content might have been changed to different links. • Technical problems: The process of communication in teleteaching is all through networks and wireless techniques. Any small technical error may cause a huge loss to the content. • Milestone: If the content in the present seminar may not be effectively produced there seems no comment, same like unidirectional method of teleteaching, where the teacher has to wait for the student's feedback to response to switch on to the next instruction. But by incorporating multidirectionalism to teleteaching includes proper planning starting from choosing the topic (s) to feedback process. • Trained expertise: The lack of technical staff or trained teachers may not give fruitful results. As non-technical staff will not have supportive attitude towards using teleteaching.
There are various factors that might have restricted the proper use of teleteaching discussed as below: Factors related to geographical region: Many of the remote or geographical regions where population are scattered in remote areas, Teleteaching might be problem for them. Thus, in those regions the concept of DE, MOOCs really works and grows.

The role of Ministry of education and research:
The ministry's role is a very important role in funding of the projects. But ministry will no longer be a supportive agency towards funding of projects in schools. Instead most of their time has been devoted in taking care of the national infrastructure related to data communication. Thus, this new technology will be helpful to educational institutions to some extent.

The role of executive board for DE Distance Education in higher education:
Many governing bodies have funded for the DE at university level education or at college level education. They have no role towards implementation of school education. Thus in this regard this light be a good idea of introducing teleteaching in all levels of educations at all stages.

Role of various Stakeholders:
We should use various electronic and video conferencing systems not only for the higher education but for the school and graduate level also. But various factors are to be required including such as:  Proper Infrastructure  Co-operation from govt. and non-govt. organizations  Supportive attitudes of all stakeholders  Good technical assistance  Teacher's expertise

RESULTS AND FUTURE WORK
As information communication technologies operates in two isochronous communications systems one is in real time interaction while other is asynchronous system that can be accessed anywhere anytime irrespective of time-constraints. But the teleteaching including video lessons or video communication is substitute for "isochronous" lectures but it does not support the "asynchronous system". In asynchronous communications such as e-mails, the electronic emails are the means for transferring the educational content, images and data that may be a substitute for video link. Thus, addition of more channels of communication increases the teleteaching quality. Thus teleteaching may effectively be used for groupware and electronic classrooms thereby increasing the chances of offering distance education through electronic resources. Thus integration of tele-teaching may effectively be used in the tele-TASK, and MOOCs platforms.
