VTS is something that is used a lot in my classroom and across my school. It is very helpful in every subject area. Trying to think of a time when we didn't use VTS to introduce a new topic has been difficult. As teachers, we are being challenged to find a resource to match every task we go through, and the first source that our team came up with when planning a math task was a related picture. Allowing students the time to question what it is and how it might relate to our new topic creates more interest and engagement in the lesson itself. We use it in social studies, science and of course reading. The best part is that students get to practice predict. I see- exactly what they see in the picture. Soon the students transfer to I think on their own. When looking at pictures from William Kamkwamba's "The Boy who Harnessed the Wind" students began to tell us (ELL teacher and myself) what they thought might be going on, and with every thought one student had, another student had a matching "I wonder." Not only are they beginning to more critically think about the classwork, but they are creating an environment where class dialogue is the norm, and its okay the question your classmates. We have also found that providing images with tasks allows students to understand vocabulary they might not have before. If they didn't know what something was, but we just saw an image, and someone else was able to name it, there was no "embarrassing" moment of having to tell the teacher or your partner that you didn't know what something meant or was.
I found the following link
