Sorting out sorting through concretization with robotics

Abstract: We describe a novel approach to algorithms concretization that extends the current mode of software visualization from computer screens to the real world. The method combines hands-on robotics and traditional algorithm visualization techniques to help diverse learners comprehend the basic idea of the given algorithm. From this point of view the robots interpret an algorithm while their internal program and external appearance determine the role they have in it. This gives us the possibility to bring algorithms… Show more

“…According to Gregorc (1982), concrete learners grasp and mentally register data through the use of their physical senses and this quality helps them to understand the sorting algorithm better since they can physically approach the concept using various metaphors. This idea is also supported by López, Myller, and Sutinen (2004) who argue in favour of the efficacy of combining traditional algorithm visualization with hands-on robots to "bring algorithms into the real physical world where students can even touch the data structures during the execution" (p. 377). On the other hand, this novel approach to reducing abstraction can be appealing to abstract learners.…”

“…Lopez has introduced a way to teach algorithms through algorithm concretization. Their approach combines algorithm visualization and robotics to make algorithm alive in the real world objects 7 . In a study done by Fagin, he reports that in different sections of an introductory course on programming, worse results were observed in the sections where they were using robots as a teaching tool versus nonrobotics sections 8 .…”
