jgs Your Project 

jgs Javier Gonzalez-Sanchez | CSC 309 | Winter 2023 | 4 Timeline Week 02 We are Here Sprint Review I Week 04 Sprint Review II Week 06 Sprint Review III Week 08 Final Presentation Week 10 

jgs Javier Gonzalez-Sanchez | CSC 309 | Winter 2023 | 5 • Demo (run and showcase new features) Github: • Source code and individual commit activities • Unit Test Cases (when needed) Taiga: • Backlogs (Product and Sprint) • Every Backlog Item has an estimation and priority approved and known by ALL team members. • Task board (per Sprint) – who did what. • Burndown chart Astah: • Reliable UML class diagram + software architecture RSM (and calculate A, I, D): • Metrics (Both Code and Structural) Core Artifacts | More are to be added later 

jgs Javier Gonzalez-Sanchez | CSC 309 | Winter 2023 | 6 § Java Desktop Application Later, we would have an additional GUI (platform) § Java or OpenJDK at least 17 Standard Libraries as needed Additional libraries using Maven JavaFX is no longer supported. Processing (PApplets) is available Team selection – balance power and complexity or portability § Later, APIs will be learned and applied. But you can start searching for local Libraries (maven repositories) Authentication ChatGTP WeatherChannel Etc. Technical 

jgs Core Ideas 

jgs Javier Gonzalez-Sanchez | CSC 309 | Winter 2023 | 8 Idea 01 – Code City 

jgs Javier Gonzalez-Sanchez | CSC 309 | Winter 2023 | 9 § Connect to a GitHub repository § Draw the city (or any graphical representation) § A class diagram § Calculate metrics § Draw a Painful/Useless Zone plot § Found patterns § Etc. § What else? Product

jgs Javier Gonzalez-Sanchez | CSC 309 | Winter 2023 | 11 Idea 02 – Tutor 

jgs Javier Gonzalez-Sanchez | CSC 309 | Winter 2023 | 12 § Think About User experience: § Install § Run § Know What to Do § Do not use a programmer's time creating tons of dialog Boxes with ”instructions.” Product 

jgs Core Ideas For these projects tutoring on some topic 

jgs Javier Gonzalez-Sanchez | CSC 309 | Winter 2023 | 14 An Intelligent Tutoring System to coach students in learning something; ej. programming Goal 

jgs Javier Gonzalez-Sanchez | CSC 309 | Winter 2023 | 15 §A coach for seatwork/homework §Responsible for planning, organizing, and delivering an appropriate range of activities (problems to be solved) for students while helping them appropriately. What is an Intelligent Tutoring System? 

jgs Javier Gonzalez-Sanchez | CSC 309 | Winter 2023 | 16 §It is not the instructor §Do not deliver lectures (or videos). §Do not replace taking a class. §It is not a tool for multiple-choice quizzes. §It is not an eBook What is NOT an Intelligent Tutoring System?
