The book "Computer Science and Technology in Schools" discusses important 21st century skills that students must possess. It mentions that computer science (CS) is the foundation of most innovations today, from biotechnology to earth sciences to national security, so it is necessary to include it in schools so that students can acquire relevant skills for the future. The book presents computer science as more than merely using technology. The subject of computer science is very broad and teaches learners design, problem solving and logical reasoning—all of which are valuable outside the computer science classroom. Teachers can use the skills introduced in this book to enable students to design technical solutions to problems in science, mathematics, social studies, art, and humanities.
