About this course: This course extends object-oriented analysis and design by incorporating design patterns to create interactive applications. Through a survey of established design patterns, you will gain a foundation for more complex software applications. Finally, you will identify problematic software designs by referencing a catalog of code smells. You will be challenged in the Capstone Project to redesign an existing Java-based Android application to implement a combination of design patterns. You will also critique a given Java codebase for code smells. After completing this course, you will be able to: • Demonstrate how to use design patterns to address user interface design issues. • Identify the most suitable design pattern to address a given application design problem. • Apply design principles (e.g., open-closed, dependency inversion, least knowledge). • Critique code by identifying and refactoring anti-patterns. • Apply the model-view-controller architectural pattern.

All in all, it was a good course. However, there were some issues. Firstly, the course notes was full of errors. Secondly, the projects did not always run immediately with the newest version of android sdk and tools. I am not so familiar with android, and each time I had to fight a few hours with these kinds of errors. The third issue was that the rubrics were not precise enough sometimes. For example, some students fulfilled the points in the rubric, but they had not addressed the issues in the assignment correctly.
Thank you for effort, and hope you can address the issues above to improve the course in the future.
Good for people already know the stuffs and need some kind of brush up. Otherwise have to be willing to study contents from web to truly understand the patterns.
Very very good 4 week course!
