The CAST UDL Book Builder is
a "free online tool (that) enables educators to develop their own digital
books to support reading instruction for children aged 3 and up. Teachers
create, edit, and save resource-rich texts."
When I clicked through to the Book
Builder I found a collection of multimedia resources that enable designers and
instructors to embed music, audio recordings of explanations or discussions,
hyperlinks, and more into the lesson books they create.
One of my favorite resources here is the student
response area, which encourages active learning and meaningful interaction with
educational and instructional texts.
For me, the “wow” factor is that
the site and its resources facilitate multimedia instruction for all learners, including those who do not
or cannot interact with visual media.
