Using visual tiling patterns to support the teaching of programming concepts

In this paper, we present an approach for introducing programming concepts using visual tiling patterns (tilings for short). Tilings exhibit regularities and their construction can be achieved through the use of simple textual commands. We show that fundamental programming concepts, such as sequencing of commands (i.e., the right commands in the right order), conditional structures (i.e., yes/no decisions), grouping and repetition of sets of commands (i.e., subroutines that are executed more than once), can be communicated effectively using tilings and in the process support students´ learning and mastering of these concepts. The use of concrete, visual tilings represents a potentially effective approach to introduce programming to students.
