The traveling salesman problem (TSP) is a combinatorial optimization problem that requires finding the shortest path through a set of points ("cities") that returns to the starting point. Because humans provide heuristic near-optimal solutions to Euclidean versions of the problem, it has sometimes been used to investigate human visual…

This study investigated ways of using computer-based learning activities to complement curriculum practices in preschool programs with an early intervention component through the use of computer-based learning activities. Particular attention was given to supporting the development of young children's early mathematical skills. The study took…
