Interactive programs and systems have become one of the most important things currently present in our daily lives and in the educational field due to the ease of interaction between society and education.A reactive program is one that has ＂ongoing interactions with its environment＂ [66]. Reactive programs include those for embedded systems, operating systems, network clients and servers, databases, and smart phone apps. Reactive programs are already a core part of our computational and physical infrastructure and will continue to proliferate within our society as new form factors, e.g. wireless sensors, and inexpensive (wireless) networking are applied to new problems.
