Activity diagram plays a vital role in Business Process Modeling as well as System modeling. In this paper, I have proposed a desktop interactive activity diagram tutorial that has been designed for educational purposes to help someone to construct activity diagram with the following features: (1) There is continuous interaction between the user and the system; (2) It provides ongoing feedback and performance updates to the user after every topic within the chapter; (3) the tutorial will generate a “Certificate of excellence” with the percentage scored if only the user has scored above 90 percentages and the certificate will be send to the user’s given email address; (4) This interactive tutorial is extensible and acts like framework in the sense that, the database is designed in such a way that new tutorials can be added to the existing application without any modification to the front end.
