Open source software allows revising and adding a new idea on them as well as debugging themselves. The open source software can be utilized as various educational programs as well as development of a commercial software products using them. MIT App Inventor, one of the block-based visual programming environments for education, supports building a local server and even revision of the platform itself by providing its own source codes. In this paper we implement App Inventor open sources on the local server. Especially we present how to revise and implement a new App Inventor platform reflecting their own requirements in schools or educational institutes and how to build a local server operating the revised App Inventor platform. They can provide more interactive educational environments to students and improve educational satisfaction through the active customizing of the platform itself such as adding new programming block components requested by students.

Block-based educational programming language(EPL) is commonly used due to its availability at low or no cost. It is also preferred tool of computing education due to its intuitive design, ease-of-use and its effectiveness in increasing algorithmic thinking abilities especially in elementary students. Physical computing is also necessary because it brings students closer to real-world problem solving by connecting the real world with the computing environment. However, due to high-cost and required knowledge in electrical engineering, many schools find the education difficult to access. The study shows significant increase in computational thinking abilities in both groups treated with EPL and additional physical computing education.
