Armoni, Michal – Journal on Educational Resources in Computing, 2009
Reduction is a problem-solving strategy, relevant to various areas of computer science, and strongly connected to abstraction: a reductive solution necessitates establishing a connection among problems that may seem totally disconnected at first sight, and abstracts the solution to the reduced-to problem by encapsulating it as a black box. The…

Soh, Leen-Kiat; Samal, Ashok; Nugent, Gwen – Journal on Educational Resources in Computing, 2005
Closed laboratories are becoming an increasingly popular approach to teaching introductory computer science courses, as they facilitate structured problem-solving and cooperation. However, most closed laboratories have been designed and implemented without embedded instructional research components for constant evaluation of the laboratories'…
