It can be used in education to study complex systems in a more modern way and is accessible to anyone who has access to the internet. However, there are still a few barriers that reduce StarLogo Nova's impact. First, it is only available in English, so users who are not fluent in English will have difficulty using the powerful tool. Second, novice users who are unfamiliar with programming may find it hard to learn how to program their models, which diminishes their ability to study the science concepts they are trying to model. This thesis takes steps to remedy these problems. First, I develop a system for translating StarLogo Nova into different languages. Then, I work with a fellow researcher in the Scheller Teacher Education Program (STEP) lab on the development of custom blocks: user-defined blocks that can be used to simplify the modeling process. Our design of custom blocks is made with the novice user in mind, creating a more intuitive custom-block creation experience than currently exists in other block-programming languages.by David Wu.M.
