I taught students how to conduct interviews with stakeholders of a project, identify the requirements of the projects, the system tasks, as well as coding with C# and WPF languages. For this course, I was responsible for leading the projects of ten groups of students where each group had 4 students during the semester. I guided students through the entire cycle of task-centered system design technique to design and evaluate interfaces based on real-world tasks. Mentoring student groups involved helping students scope their projects, helping with technical problems, regular meetings with students to discuss problems and suggest possible alternatives to improve interface design. Finally, I evaluated the projects through review of their portfolios and final project demonstrations.
