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.

SW education is considered important in the present age where various sciences converge. According to this tendency, SW education was included in the regular education course in Korea, which aims to develop the learner's CT. Therefore, researches on CT and educational tools are being activated. App Inventor is a simple app development tool that has many advantages over traditional tools. In this study, we developed and applied a SW instruction program that uses an App Inventor to develop CT for elementary school students. Moreover, CT was classified into two elements-calculative perception and calculative creativity- and performed tests after applying SW instruction programs. Furthermore, attitude towards computer were classified into three elements-c computer anxiety, computer preference, and computer confidence- and conducted tests. After performing paired t-test pretest-posttest matching samples on test outcomes, it was found that the CT of the learners who applied the program was increased, and the attitude towards computer also showed a positive change.
