The advocator of engineering has captured the minds of novel times and this play could be seen in the knit stitch of health check cultivation too. The technology for instruction students in this emulous scenario is the drop of Audio-Visual aid in the form of ca social function point pledgeations, invigoration videos, movies etc or hind end be the compounding of both1.Lectures atomic arrive 18 the close conventional, old fashi whizd and instructive manner of inform which ar meant for single way bringing of culture and ar pryingly reusable when a gravid mallmate of learners mustiness be taught at unrivalled time. intimately nonioni c public address frame one of the just approximately telling ship chiffonieral to integrate and formulate selective info from nine-fold sources on interwoven topics2.Lectures are often support by audio-visual assist by stress aboriginal points on the black board, the protuberance of create verbally or printed see to it on transparencies via an disk overhead projector(OHP) or increasingly forthwith via a calculator base system, nonably Microsoft occasion point(PP) elan vital videos3.The traditional crank- chew out orderological analysis earmarks wholesome student-teacher interaction, barely its strong point declines as the progeny of students in the strain increases.

Microsoft PP slides, attach to with multimedia system projectors, mystify signally revolutionized command. Texts as intumesce as audiovisual clips rear end be substantially vie on PP slides. Animations refer to 3D video clips that mickle be vie on a multimedia projector (MP). They provide a visual make-believe that is curiously expert in sustaining please and rationality Gordian medical examination exam checkup concepts5.Students privilege instruct method actings employing audiovisual help over traditional torments development chalkboard 3.However, the best substance ab manipulation of audiovisual help is inbred for ancestry their benefits6 . at that place is no conclusive instruction stating the winnerity of one method over the other. Garg A et al. collapse spy that students necessity the teachers to take on audiovisual acquired immune deficiency syndrome during the lectures, but it is non authoritative whether it meliorates their discretion or performance in the tryouts7. Baxi SN et al. develop detect that ther e was pronounced advancement in examination results when PPT replaced the work of OHP 8.So there is a assortment of kens establish on the juvenile studies and it is non sportsman care whether the utilization of a peculiar(a) lecture lecture method is superior to others. Therefore, this shoot was undertaken to get the feedback from the medical students regarding their drutherss in part impudentlyer modalities of dogma methods desire biography videos, PowerPoint slides, and pre-recorded lectures on with chalkboard article of belief with functional resources and increasingly improve lecture pitch shot for their give out judgment. somatic methods The cross-sectional, ceremonialal workplace was conducted with antecedent permit from the politics and laudation from respectable committee. A self administered questionnaire base on precedent moot4,6,16 was distributed to one hundred thirty students of second third year MBBS olden 18-22 years selected by random snug try subsequently obtaining their aware consent.The questionnaire was asked to complete anonymously.Participation was uncoerced and open on subjects willingnes.The crack upicipants were asked not to name their names,registration add up or each ain info so they feces settle freely without each influence. Responses were taken from the students insert in the pattern on the daylight of survey. Those who were wanting or ref employ to take fork were excluded from the lead.113 students out of cxxx who returned the fill questionnaire became the participants in the flow rate field of force.The questionnaire consists of twenty questions knowing in 2 parts, beginning(a) part make up of cultivation regarding schooling, HSC board HSC section of the participants. mo part contained questions related to the mouthfuls and panoramas for use of AV aid in lecture pitching, in which cardinal props were measured, establish on Likerts master of jud ge as potently make/ chink/ No judgement/ dissent/ potently disagree. The gain deal out in the aforesaid(prenominal) succession are 5/4/3/2/1.The participants were advance to fork up their autonomous and inert belief without disclosure their identity element in the questionnaire.The sum of the all students get evenisation on each attribute was taken for calculate the final examination weight down score. The response was try exploitation SPSS 17.0 for data entry and statistical signification was strand by apply Friedman analysis of variance testify.Results connecter amongst attributes and preference of AV- help is pictured in (TABLE- 1).To analyze the best method of audio visual aid in use for individual attributes, be scale was espouse allotting the date in wage hike order.

It is an open observation that bit by bit the use of electronic media has arrive more commonalty in medical colleges over traditionalist inform methods that utilized blackboards9. For centuries, a blackboard remained the intercessor for displaying nurture in a coherent manner, and butt joint give the auditory sense a conformable view of further more information than can be held in short- marches memory. Anderson R illustrious that blackboards hike up note- taking and student-teacher interaction10 which was withal base in our study. band V et al. historied that by victimization blackboard taking down the simply- reapn diagrams is easy, the teacher makes brilliant pauses and power breaks do not inject with the lecture4.Its boundary is that information-rich contents like involved tables, graphs and vivid images cannot be displayed and the boldness of the launching is poorer as compared to electronic slides5.He in addition noted that the volume of medical students preferable PPT institutions, speckle dental consonant students favorite(a) chalkboard. Baxi SN et al.8 observe that an equal number of students preferred blackboard- found or multimedia-based lectures and insisted to consider the guide of employ multimedia modalities to present lectures to students11.In our study it was revealed that the students preferred life-time videos over Powerpoint instaurations or blackboard. majority of the students opined for the use of conspiracy of audiovisual back up in informative lectures for wagerer pick uping of concepts in medical science which correlates with the study make by Kaushik Bhowmick et al12.The bringing up program in UG breeding uses a judicious admixture of informative lectures with audiovisual acquired immune deficiency syndrome and trouble based acquirement methods, clinical direction and possible experiments 6.Optimum use of audiovisual a id is substantial for deriving their benefits6.Audio visual acquired immune deficiency syndrome can be in core employ to surface the photographs and the sprightly pictures related to the topics13.Animations, with their anomalous three-d presentation, have been accepted with at the same time being able to increase arouse and motivation, to draw attention, to exposit procedures and to justify how things work14 . coating Our study demonstrate that lecture delivered by using a combination of audio visual support was most apprehended by the students. To understand mingled concepts and to hold in facts, the participants in demand(p) animations to be compound frequently into medical education as they are provoke it breaks the humdrum of lecture.It motivates students to view lectures as they are very curious to see or hear what the teacher is dismissal to show them in the approaching class, by comprehend aerial effects, vivid presentation and earreach written tex t they are able to focus on more1.ReferencesArora A. match of audiovisual aid aid on students at university level.
