Scratch is a visual programming language developed by MIT and designed to facilitate the teaching of programming to children. The first version appeared in 2005 and since then it has been used in different educational levels and with diverse objectives: to improve the learning of some subjects as mathematics or music, to work on computational thinking, to reduce gender differences in technical careers and to facilitate the learning of programming in post secondary education, among other uses for teaching and learning purposes. The use of Scratch has increased over the years and, accordingly, the scientific papers that present and discuss the educational experiences around it have grown too. In this article we present a scoping review that we are conducting of all the scientific literature around Scratch from the years 2005 to 2018. We explain the procedure followed to perform the search and selection of articles and the categorization of the scientific production. Some preliminary results are also presented.
