Audio-visual tools are being used in fields of manufacturing. It has already become a part of our daily life and taking a main contribution in developing of fields. As well as, teaching technical courses through audio –visual tools in English language are important in education. Today our students prefer learning technical subjects through audiovisual tools to learning without services of media. Learning technical courses by audiovisual equipment gives more effective because, nowadays we knows our students interesting in media tools so they are easy to learn their subjects. In additional, we can divide teaching systems into two groups: traditional and modern. The traditional method is taught only one way that are listing and writing but modern method includes in service of media. Quality training for teaching technology, possess the necessary competence in relation to mandatory for the compliance of the qualification level spеnding amount of knowledge necessary to acquaint him with the most recent information. At the same time we should not forget that the specifics of the process of teacher education involves the synthesis of a large number of humanitarian knowledge and modern information on the latest developments in the field of engineering, technology and science. Given the large amount of relevant information and high dynamics of its changes, the problem can be solved only with the active use of information and communication technologies.

1.                 Introduction

May 20, 2011, according to decree of the president of Uzbekistan «Higher education institutions to strengthen the material-technical base of highly qualified specialists and measures to improve the quality of the resolution» issue № 1533 and March 26, 2013 “Information and communication technologies in the field of personnel training system on measures to improve” issue № 1942 dated responsibility is to make the learning process of modern information and communication technologies, and innovative teaching technologies have their place.

Today, English language plays an important role in our life and people need good communication skills in English to prove their knowledge. In order to share or update their technical knowledge, students should know English language. In other way most of equipment’s instructions are written in English. The use of devices or audio-visual materials will stimulate the greatest number of senses. For this reason, good teachers have always used devices or audio-visual materials. A device is any means, other than the subject-matter to the learner. This paper focus on how to use audio-visual tools in teaching of technical courses in English language.

1.             Technical audio video tools

Science has contributed a lot in the field of technology which has made our life easier and comfortable. In every sphere of life, the dramatic revolution of technologies has been influential. The field of education and training is not out of this. Now-a-days, teachers are using different technologies in their classes to make it different and effective from the traditional ones. One of these computer and overheads.

Computer:

Computers have changed the way we work, it will be in any profession you have or see. Therefore, it is only but natural the role of computers in education has been given a lot of importance in the recent years. Computers play a vital role in every field. The researcher uses the computer as a technical tool and they copies all the syllabus in detail disk and present every student of experimental group with this disk.

Overheads:

Second name of Overheads is OHPs, slides and transparencies. Writing on transparencies and using an overhead projector to share them with the class helps facilitate group discussion easily. Groups in the class can also quickly record their work and conversations to share with the rest of the class. Such strategies particularly benefit students who respond to visual learning cues. Although overhead projectors seem outdated in more technologically advanced classrooms, they provide a valuable back-up if the Internet or another technological tool fails to work, and the teacher needs to share visuals with the whole class. Teachers can keep salient information on a transparency to continue with an alternate lesson.

1.          Impact of audio video tools on teaching technical courses in English

Today, we are using wide variety audio video aids in education processing. Until now, the problem of the use of audio-visual aids has been examined from an intellectual angle. It also includes important practical and technical aspects. To tell the truth, techniques cannot and should not be separated from pedagogy. We have seen that audio-visual aids cannot be separated from educational materials as a whole, this conclusion being thrust upon us by the attitude of the user when confronted by these materials. Now this same user — whether a teacher, a professor or an adult educator — does not act any differently when pedagogy and techniques are involved. He can never be purely a pedagogue or purely a technician. It is clear, therefore, that the pedagogy of audio-visual aids cannot be separated arbitrarily from audio-visual techniques.

No one can hope to achieve good results unless he is a sensitive pedagogue and a skilled technician. The problem must be solved globally. Today’s technology offers many choices to the informed educator who wishes to capitalize on a new generation’s appetite for multimedia presentations. Lesson plans that incorporate the use of audio-visual aids should be consistent with curriculum objectives and not segued improperly.

Media presentations can also enhance lessons by capturing students’ attention and providing visual or auditory examples of subjects discussed in class. Make sure that you preview any resources you

plan to use in class, and cue them to the appropriate spot before class begins. Providing a viewing guide or asking students to pay attention to certain issues will help focus their experience and prevent them from tuning out. Stop the video at least every five to 10 minutes for discussion, questions, and to reinforce important points. Try to place copies of video or audio used in class on reserve in the library for students who missed class or would like to review the materials.

Auditory learners focus more on the spoken word rather than the written one. Taped recordings of lectures or movies are helpful to auditory learners because they pick up on speech nuances such as tone and pitch. Computers with speech-recognition devices will also help auditory learners to process and retain information better than just reading from a textbook. Students with hearing disabilities will also benefit from teachers who use microphones while lecturing.

A device is an incentive introduced into the method of teaching for the purpose of stimulating the pupil and developing understanding through experiencing. The basis for all learning is experience, and usually the most effective type of learning is gained by concrete, direct, first-hand experience. Teachers are often unable to give pupils first-hand experiences and resort to the written and oral use of words. The experienced teacher, however, realizes that the use of words alone cannot and will not, provide vivid learning experience. Good teachers are constantly on the alert for methods and devices that will make learning meaningful. With the wise selection and use of a variety of instructional devices or audio-visual materials, experiences can be provided that will develop understanding.

1.           Conclusions

The main purpose of this paper was to find out how to use of audio-visual aids facilitates on teaching technical courses in English. In other case of particular importance among humanities courses has a course «Philosophy of science and technology». It is designed primarily for those students who plan to further increase their level of education in graduate school. The tools presented in this paper are good examples of this kind of applications, where technology meets education to improve the learning experience and, at the end, the quality of life of final users. Thus, one of the easiest and least expensive ways for teachers to prepare the most effective teaching materials is to look around and never underestimate their sense of creativity. Teaching with technology is changing the face of education. Teachers have more resources available to present information, and students have more opportunities to engage in learning. The teaching and learning are more effective.

Even if you’re in the right mindset, ready to learn, and committed to seeing your event succeed – and honestly, if you’re here reading this, that’s a fair assumption – truly understanding your event’s audio visual technology can be challenging. With so many moving parts comprising the sights, sounds, and experiences that you’re eager to convey to attendees, it’s completely understandable if there are a few terms you don’t recognize yet. Thankfully, there’s still time before your event to brush up on the basics of AV technology. A quick study session will enable you to not only navigate your event’s needs like an industry pro, but also understand the nuances of business contracts for AV service at your venue of choice. But before we jump into technical AV technology terms, let’s answer the very basic questions.

What is AV & AV Technology?

AV is an abbreviation for Audio Visual, which is used to describe electronic media that possess an audio (sound) and visual (sight) component. AV technology refers to the actual equipment or tools that convey these components, such as lighting, projectors, speakers, and displays.

The Pre-Show: Audio Visual Equipment Considerations

While it might be tempting to jump right into the proverbial wires and plugs of navigating event audio-visual equipment, it’s not where you should start. To better understand what AV technology can do for your event, you need to know how you’ll get it all in, out, powered, and connected for use during the event.

Below, some common client scenarios and industry terminologies to familiarize yourself with AV equipment and related pre-show AV services:

Scenario 1: “We sent the exhibitor order form to the keynote speaker and discovered he needed another microphone.”

• Exhibitor Order Forms: While you undoubtedly have a vision for your event, remember that it isn’t a given that every presenter shares your exact idea of adequate audio-visual coverage. An exhibitor order form is essentially a list given to your speakers prior to an event, asking them what specific technology they’ll need to deliver a smooth, clear presentation to your attendees.

Scenario 2: “We’re planning the load in at 8 am, starting at the loading docks in the rear of the building.”

• Load In / Load Out: These terms refer to one of the most important aspects of setting up audio-visual equipment for an event – and believe it or not, they start before a plug ever finds an outlet. Physically moving in speakers, screens, projectors, and control systems at the right time and place is the effort that will keep your event on-track and on-schedule.

Scenario 3: “We felt pressured to use the in-house supplier, but went with a great third-party provider that had the colored LED light wall that we wanted for the big speech.”

• In-House Supplier / Third Party Provider: Many larger venues offer either an in-house audio-visual team or have a preferred provider ready to recommend if your event needs one. While there are benefits to both approaches, third-party providers – those that aren’t built into the venue – often offer access to more innovative technology solutions, as they aren’t restricted by the venue budget. The other side of the coin is that they may be less familiar with the venue and its capabilities – an obstacle that’s easy to overcome, however, with enough time for research.

Fine Tuning: Physical AV Components

It’s not all screens and wires – a complete event audio visual setup requires a lot of support of the physical variety as well. Depending on the height, width, and power capabilities of a given venue, you might require all of these elements to have adequate AV coverage for your audience. Read on to learn more about the subtle nuances of physical AV components:

Scenario 1: “When we needed the sounds of the video to reach the back of the auditorium, suspension rigging for the speakers helped our team achieve better acoustics for the entire room.”

• Rigging: You’ve probably heard of this word in conjunction with ropes or sailing ships. In an AV context, it points to the equipment providers rely on to suspend components, such as projectors, microphones, speakers, or lighting, from the ceiling of a venue or room. Most large-scale setups will need some sort of rigging, so be sure you have information about maximum ceiling height or load-bearing weight to pass on to your audio-visual services provider.

Scenario 2: “The trusses gave us the ability to make a “backstage area” right on stage so the presenter could line up her various props out of the audience’s line of sight.”

• Truss: While technically a component of overall rigging, these aluminum tubes assist with non-AV related stage dressing needs, such as supporting drapes and props, as well as wires and lights. Trusses typically break down for easy transport, but will require extra load-in and load-out time to set up and take down after an event.

Scenario 3: “The front of house setup was surprisingly compact given the auditorium’s square footage, and left plenty of room for adding additional audience seating.”

• Front of House: This is a shorthand term for “where the AV team will set up their control center.” It’s most often found against the front entrance wall of a presentation space, ideally to the far left or right of the door to stay out of the way. It is typically positioned facing the stage for visual cues and monitoring.

The Warm-Up: Audio Visual Technology for the Masses

The main stages and meeting rooms are set up, and you’re starting to feel confident about the direction of your event. Now is an important time to remember that your attendees aren’t just interacting with audio-visual technology in sit-and-watch sessions, speeches, and classes – they’ve all come with their own technology, such as smartphones, tablets, and laptops, ready to hashtag, post, and share. The better they’re able to use those tech tools, the better your event will look to potential attendees for next year’s event on social media. Leverage the latest technology that’s available and take your event to the next level. Below, a glossary of the tools of the trade to keep top of mind when orchestrating your next corporate event:

Scenario 1: “When the speaker suggested session attendees bookmark her website mid-presentation, the audience was grateful that the event’s sponsored WiFi gave them fast access to the page.”

• Sponsored Wi-Fi: All of those attendees need to be able to access the internet in order to post, visit websites that speakers suggest, and so on. Sponsored wifi gives them that option and gives you a valuable chance to share your own brand or sell placement for another at the same time. Not all venues have this capability, so be sure to check your en masse internet options well before your event to avoid unpleasant breakouts of “low bars syndrome” and frustrated guests.

Scenario 2: “We couldn’t find a flight out to the conference, but thanks to live streaming from the session, we were able to watch the once-in-a-lifetime interview from our favorite author from our home computer.”

• Video Conferencing / Live Streaming: Advances in audio-visual technology for events have enabled organizers to reach bigger audiences than ever before, even if they aren’t physically present. “Streaming” technology refers to combinations of components that record and broadcast a live feed or audio and video to the internet as it’s physically happening elsewhere. This can be used to send out an event session to members across the world, or to bring a guest speaker onto an event screen for a local audience if he or she is unable to physically attend. Holding a video conference allows participants from all over to communicate with each other in real-time through sound and vision. Some events even use these methods to monetize their sessions by streaming individual informative sessions and offering certification classes afterwards.

Scenario 3: “She had a great question for the presenter, but she should have had a wireless microphone because the back rows couldn’t hear what she was asking.”

• Wireless Microphones: While this term is a little self-explanatory, many event organizers incorrectly believe that individual presenters and speakers are the only ones that need wireless microphones. Audience interactions drive engagement at events, so in addition to the familiar tiny mic clip / battery belt clip combinations, be sure that you have a wireless microphone option that can be passed through the audience for questions and comments that all can listen and respond to. Encouraging communication from both sides is extremely important for engagement and collaboration.

The Main Event: Audio Visual Equipment Done Right

Now that you’re set up and connected to your audience, it’s time to “seal the deal” with an above-the-bar AV presentation. Crisp, clear images that put every PowerPoint slide in the spotlight, and audio that’s loud enough to hear – but not so loud that every ‘S’ sounds like snakes have escaped from the podium.

While there is no universal list of settings to ensure perfection at every event and every venue, there are a few areas of focus that you can’t afford to overlook when it comes to your AV event setup:

Scenario 1: “When the older screen only offered a 4:3 aspect ratio and the presentation was displayed in 16:9, the attendees seemed to stare more at the ugly black bars than the speaker.”

• Aspect Ratio: These numbers, typically presented in an X:Y format, correspond to the proportion of a screen’s width to its height. In other words, if the ratio of your projectors doesn’t match up with the screens they’re projecting on, you’ll either get an image that will have black bars across the top and bottom, or along the sides of the image or video. Either way, it paints a distracting picture for the audience and could potentially cause the message to be lost in proverbial translation. Make sure to adjust either component accordingly to make certain your displays look professional and clear.

Scenario 2: “The clarity offered by HDMI cables is the difference between a clear, high-definition movie played on a flat screen and the same movie played on a grainy, old-fashioned television.”

• HDMI: Most people are familiar with this acronym from home television and computer monitor hookups, but it’s especially important during large-scale events. Short for High Definition Multimedia Interface, HDMI cables and ports are the go-to for all professional display and sound needs in the event sphere. In addition to the cables and connectors that will come with your audio-visual provider’s equipment, make sure to keep dongles and adapters on hand for common devices so your presenters always have a ready AV solution for displaying or playing files.

Scenario 3: “The speaker was able to relax and connect with the audience because he knew he could rely on the audio visual technician to follow the cue-to-cue faithfully.”

• Cue-to-Cue / Run of Show: Your AV team needs to know when to cue up lights for presenters, when to start and stop certain AV aspects like music or video, and sometimes even when to change PowerPoint slides. A cue-to-cue or run of show script lays out each change in an easy-to-follow format so that your session presenters and keynote speeches look polished and professional.

Scenario 4: “Thankfully, the nervous performer was able to reassure himself that his tie was on straight with a quick glance down at the confidence monitor on stage.”

• Confidence Monitor: This unique piece of audio visual for events is one of the few that isn’t set up with audience consumption in mind. This small screen is typically mounted flat or at a slight angle on the front of a stage, facing the performer or speaker. Through the use of Image Magnification (I-Mag), it allows him or her to get a quick glance at what they look like to the audience, allowing them to adjust accordingly – clothes, facial expressions, gestures, and so on – if needed. Additional uses of confidence monitors is to display presenter notes, or the master PowerPoint slides so that the presenter needn’t turn around to see what is on the screens.

Summary

While your event will undoubtedly have its own unique range of audio visual technology, these common devices, components, terms, and practices will ensure that you know where you stand from the start. After all, what is audio visual technology if not a tool to make your event the best it can be? Discuss your needs, expectations, and event vision with your audio visual services provider and two things will become perfectly clear: your displays and sound quality, of course!
