Here is an insightful article from OUP ELT Blog.
The OUP ELT team says, “Let’s take a closer look at the features of Classroom Presentation Tools. Although all of them are important and useful, we are going to highlight five of them:
1. Embedded audio and video
All audio tracks and videos are just one click away and embedded in the right place in the Student Book or Workbook. The audio player provides great listening practice! You can adjust the speed of the track to support your students when they don’t understand or challenge them to listen to it faster. With the AB loop, you can select one specific part to play on repeat.
The video player supports your teaching by showing students the use of the language they are learning. One recommended strategy is to play it without sound first to make your students guess what is happening and help activate their schemata about the topic. Some videos have the script embedded in them to use them for role plays or discussion.”
