An Enhanced Video Assisted Health Education System

Methodology plays a dominant role in any type of research. Research is a well-planned, systematic and cautious endeavour. It is a process, a way, a method, a means of finding out something new, or getting better understanding of something that we know already. A better understanding will take us nearer to reality and lead to better, wider and more forms of applicability of the phenomenon being researched. Selection of the research method was fully depending upon the nature of the study units to be followed.The purpose of the study was designed to found out the effectiveness of An Enhanced Video Assisted Health Education Module (VAHEM) in enhancing knowledge, Skill and Attitude among Secondary Teacher Trainees.


INTRODUCTION
The IT infrastructure is playing an increasingly important role in the success of a business.Market share, customer satisfaction and company image are all intertwined with the consistent availability of a company's web site.Communication is not simply a matter of transmitting information.Effective health communication involves the transformation of health knowledge into messages that can be readily understood, accepted and put into practice by intended audience.Health education is concerned with establishing or including changes in the attitude and behaviour of individual and group that promote healthier living.It also provides the basic knowledge and skills that equip the individual to make positive health choice.Video show teaching modules have been claimed to be more successful at holding a patient's interest when compared with other methods of information for delivery, allow patient control and superior recall compared with other sources of information.This method has strong influence on the degree of learning and the retention of information.Many studies in different fields like in case of prostate surgery, colonoscopy, and self-insulin administration in case of diabetes by pre-post video assisted teaching showed the increased knowledge, attitude, practice, co-operation towards the particular field.
Video technology offers a considerable potential for improving the quality of education and stimulating interest and involvement in academic excellence.Since most of the schools have the gadgets, this experience has helped the teachers to be equipped in using video programs in their classrooms.Technology provides students with multiple pathways to learning.Today, educators accept the fact that the computer has indeed succeeded in providing an individualized learning environment that is too difficult for a teacher handling whole classes.This is so, since the computer is able to allow an individual student to learn at their own pace and remain motivated in learning through the challenging virtual learning environment.In the past, students solely learn through traditional teaching.Today, as innovations in teaching-learning have been developed, teachers have integrated these current technologies along with the other innovative teaching methods in their classrooms.Computer-assisted instruction, particularly the video technology, is now a primary and eye catching instructional material in schools.This type of instruction enables the learners to go through the learning process step by step.However, teachers still play important role for they serve to facilitate the auto-instructional process or supplement the learning process in its entirety.With so many positive claims, video-assisted instruction could become powerful in socializing effects on students, and indeed, brings more interactive learning into the crowded classroom.Technology is here and the trend nowadays is clear.Using computer for instruction is quite novel, innovative, and new.Therefore, the advent of computers through video-assisted instruction has made great impact on many fields of human endeavour, including education.There has been considerable optimism expressed concerning the future use of computer, mostly the video-assisted instruction in education.Along with this new innovation there is a need to evolve certain clear guidelines for the future trends and criteria for consideration in the matter of developing and validating video software for teaching and learning of Science and Health.In teaching, it is very important to keep abreast with technology because learning can be fed and stored into them.Nowadays, learners are generically termed as electronic learners wherein the teacher will utilize instructional tools such as the electronic media, including phone, bridging, audio and video tape and a video, as well.There are many positive effects of using video-assisted instruction in preparing blackboard augmented lesson.It adds action to the information which students receive through one way process and help students see the unseen, to test the theoretical concepts, and to comprehend abstract ideals.Students taught with computer-assisted instruction had better attendance rates, showed higher motivation, and cooperated better with peers.This student-centered approach technology provides multiple pathways of learning.Lastly, as the number of computers in the classroom increases, students are given opportunity to engage in a variety of learning modalities.Computer technology for school purposes has already been available, but it is only in the last few years that computers have begun to have a major impact on classrooms and schools.Using computers for instructional purposes have become routine for many educators and if used properly, computer holds great promise.Its potential far surpasses that of such prior instructional innovations as television, teaching machines, and projectors.Although better visual images can be obtained with slides, and better sound from audio equipment, there are things the computer can do that are beyond the capabilities of the former.While a large mainframe computers are still used and will probably still be needed for several years to come, the growth of video technology would allow learners to have completely different types of experiences.The computer can be a tutor, in effect, relieving the teachers of many activities in their personal role as personal tutors.It should be made clear, however, that the computer cannot totally replace the teacher since the teacher shall continue to play the major roles of information deliverer and learning environment controller.It is in this premise that this study was conducted to give teachers essential information about the impact of video assisted instruction to pupils' learning.Video-assisted learning is a growing strategic teaching approach in many modern classrooms.Educational videos are now more accessible than ever and teachers are increasingly making use of this readily available resource.Video-assisted learning at its core is simply using videos in lessons.But as technology has advanced, so has the dynamic between student and teacher.This means that nowadays, many schools are beyond the times where all students simply strive for the same goal of just a job and merely just sit quietly and listen.We want them to become innovators and creators, to argue and question the things around them, and to grow up to be better wellrounded, and happy individuals.Videos, television, and movies are nothing new, but how we can optimize them for learning is relatively new.Videos can help students perform better not just academically but also emotionally and socially.Videos can provide students a completely new world, even if the scope is still quite limited.

VIDEO ASSISTED LEARNING
Video-Assisted Learning (VAL) is defined as a strategic teaching approach to using videoseither educational or conceptual -to improve a student's comprehension, cognitive ability, or social-emotional skills.What that means is that videos are more than just a way to pass time or provide additional information on a specific learning objective.Video-assisted learning takes videos and transforms them into an important part of both general education and student wellbeing.Videoswhether they are short, targeted clips or television programshave some proven benefits to different aspects of a student's development and educational progress.How this impacts the student depends on the type of video you use and the practices you wish to use.Video-assisted learning is not ideal for isolated use but rather should be an addition to the already existing curriculum or individualized education plans (IEP).

Figure-1: Video Assisted Learning
Figure-1 shows the Video Assisted Learning scenario.Educational supplements refer to the videos, short movies, or films where the primary purpose is to educate on a particular topic or learning objective.Common types of educational videos are short clips, documentaries, tutorials, some cartoons, and other forms of video media with the intent to teach.These videos are used purely for supplementary materials to help reinforce ideas taught in the classroom.Many teachers are probably familiar with this form of VAL as they are an easy and effective way to enhance lesson plans that may be lacking in otherwise physical materials.Most modern classrooms are equipped with a projector or laptop, and even if you are a true 'old school' teacher, you probably at least have a TV with a DVD, Blu-ray, or VHS player where you can play an educational video.
