Teacher as teller is a short talk that provides the background information to the reading or viewing. It ensures that all students approach the reading or viewing with the necessary background information.
It is much easier to understand what we read when we have some knowledge of the topic. This is, of course, something of a Catch 22 as background knowledge is acquired by reading.
When I show teachers this tool, they get very excited because it provides many ways in which vocabulary can be taught and learned.
A great deal of vocabulary in subject specific texts is new and unfamiliar to students. Some words have been heard but not seen in writing, making it difficult for students to recognise and pronounce the word.
Sometimes teachers may want students to read around a topic. To do this we need to provide students with similar information at different levels of difficulty.
It is very frustrating for high school teachers to have students in their classes whose reading abilities are not strong enough for them to be able to learn the content and skills necessary for success.
