Current computer education is difficult to educate basic concepts and principals of the computer science because the 7th curriculum of computer education is focused on the application of software. According to the ACM K-12 report about the computer science education model, current computer education is taking the wrong way and we should put the highly priority on the education of the fundamentals through programming languages for a better computer education oriented to the computer science. This paper introduces a new object-oriented educational programming language "Dolittle". The design principals of Dolittle are simple syntax of Korean, incremental programming, text based programming, aliasing of function, and object-oriented programming. Being applied to middle school classes, we can confirm that Dolittle is easy to learn, and gives rise to high interest and keeps interest through a course, and also is of great practical use in class for programming novice.

Educational Programming Language (EPL) should be learner-friendly and easy to use. Dolittle, an object-oriented educational programming language (EPL), offers programming environment which can be programmed in Korean(Hangul). However, since some Dolittle commands are not appropriate to elementary and middle school students, it shows limitations for learners to express programming process. In this paper, we developed a set of 1:n multi-reserved words which are able to program with Korean linguistic characteristics as well as considering learners' differences, preferences, and applicable areas. The conclusion in the paper showed that programming with this 1:n multi-reserved words helped learners concentrate on problem solving regardless of the reserved words.
