Russell Shackelford is currently the Director of Lower Division Studies in The College of Computing at Georgia Tech. He holds various degrees in Computer Science, Education, and Psychology. His work is aimed at integrating research and practice concerning computing education, and at the development of computing tools and associated human methods for supporting education. Besides having a well-rounded education, Dr. Shackelford also loves baseball and occasionally can be found walking on the beach somewhere in Alabama.

Klappentext

This book prepares students for the world of computing by giving them a solid foundation in the science of computer science - algorithms. By taking an algorithm-based approach to the subject, this new book helps readers grasp overall concepts, rather than getting them bogged down with specific syntax details of a programming language that can become obsolete quickly. By working with algorithms from the start and applying the concepts to the real world, students will understand the power of computers as problem solving tools and learn to think like programmers.
