Computational Thinking: Searching To Speak is a glossy booklet that shows computational thinking in action embedded in a story about helping people with disability, even without technology. It shows how the separate elements of computational thinking combine in interdisciplinary problem solving. Along the way it teaches some core search algorithms. It is written by Paul Curzon of QueenMary University of London based on the cs4fn approach.

• Explore the design of an algorithm to allow someone with locked-in syndrome to communicate. Locked-in syndrome is a condition resulting from a stroke where a person is totally paralysed. They can see, hear and think but cannot speak. How could a person with Locked-in syndrome write a book? How might they do it if they knew some computational thinking?
• Learn about computational thinking, search algorithms, linear search, binary search, divide and conquer  and comparing algorithms.
