Evaluate 1.1.2 Quality Feedback Quest

In your blog, provide a student work sample and accompanying feedback that showcases some of the expectations listed above and offers a sound example of quality, authentic feedback. Discuss aspects of the sample that align with the best practices discussed in this quest.

The assignment was to write a menu-dirven program.

Richard, This is a very good example of how to break down the program into parts. You did a nice job of creating managable methods and then reusing them when appropriate. The program is excellent and I would like to use it next year in the AP class when I speak of methods. Can I?
