The approaches to teaching language well have undergone major changes and heated debates in the field of second language acquisitions

3. Videos provide context to help understanding
Unlike reading texts and listening activities, video provides strong visual cues. These help learners understand whats happening even when the language is hard to follow.
In some cases, you can even play videos without sound at first and have students guess whats happening. This works in a similar way to a reading prediction activity and helps prepare students.
Documentaries often also provide text overlays that share additional information with the audience. This, in turn, helps with general understanding authentic content which is key to students language development.
4. Videos expose students to a variety of language and cultures
Video offers unlimited opportunities to expose your students to different accents and dialects of English.
When students travel, meet new people or start working they are likely to speak with people from all over the world and that will probably be in English.
Its, therefore, a good idea to use video to expose students to a range of English accents. This will help them become aware that there is more than one variety of English and will help them get used to hearing English spoken in different ways.
Whats more, globally, there are many more people who speak English as a second language than there are native speakers. So its a good idea to expose your students to a variety of non-native speakers in videos too.
5. Videos introduce culture and new ideas
Videos can bring the outside world to students, introducing different cultures, new places and ideas. They provide a great way to integrate new content and language learning at the same time giving students the opportunity to learn about a whole range of subjects and ideas, at the same time as learning English.
How to choose the right videos for your learners
Its important to select your video material carefully, considering the age, language level and interests of your students.
Younger learners tend to respond to cartoon-like videos with stories or fun characters, while teenagers and adult learners are more likely to be interested in documentary style films, humorous videos, or content that relates to their interests or work.
Of course, its also important to consider how advanced your learners are when selecting content if the video content is too complex your learners will find it hard to understand and might lose motivation and interest. Conversely, if its too easy, theyll also get bored.
Its also key that you design and grade classroom activities appropriately. Even low-level learners can answer simple questions about complicated subjects and easy video content can be used to spark high-level debate and conversation.
3. Internet and YouTube
Internet and You tube are also one of the audio visual aids types. Most of people in the world now know that internet is useful for education in some case, especially for students when they get some online task from teachers. Through internet, students can do browsing activities as much as possible they want to watch. For instance, when the students want to watch advertisement products in google, automatically they get it fast. They just determine the key word taped in google search engine. They can read and hear some a new language program. Another important difference presented by the Internet is that the quality of presentation of information is not necessarily a clue as to the quality of the content the way it might be with a print publication.
4. Television
Allen states that educational television has received the most concentrated study of any of the Audio Visual materials during the past several years. TV instruction was found to be just as effective as regular classroom instruction in teaching training subject. Today, many programs on TV have developed from year to year whether educational channel programs or commercial ones. Indeed, on TV serves a lot of advertisement that can be seen directly. It also has some advantages in practice. Through TV, people can know some issues being occurred in real life on TV news. They also get knowledge in some case.
