A Method of Modifying a ScratchJr Project by Resorting to JSON Stored Project Data

Abstract

ScratchJr, a programming tool developmentally appropriate for preschoolers (children age 5 to 7) is intentionally designed without the possibility of externally adding image and sound files. It can create difficulties for adults (teachers and parents alike) involved in pre-school activities with ScratchJr. This paper presents the structure of ScratchJr projects and a manner in which they can be modified by adding external images and sounds. It also presents the JSON project information code needed for the proper functioning of the programme with added files.
