Session 5 Preparation

Quiz

Go to Moodle to find the Quiz for this Preparation.

Do the quiz as you watch the videos and do the reading. The quiz follows the same order as the videos/reading do.

You can access the videos from here or from Moodle; they both point to the same place.

Videos and Reading:

All of the following are required except items labeled Optional are, well, optional (i.e., things that may be interesting but do not directly pertain to your success in this course).

Introduction to Piazza
- You should have received an email whose subject was CSSE 120: Instructions for an assignment on Piazza.
- Do the assignment (per instructions in the email) if you have not already done so.
- If you have NOT received the email, ask your instructor to resend it.
Reminder: Work efficiently!

For most problems, if you are still working on the problem after 5 (or at most 10) minutes on that problem:
- STOP working on that problem.
- Continue to the next problem.
- At the next class session (or sooner), ask for help on the problem(s) that you did not complete.
Debugging: Being more adept at debugging (i.e., fixing errors in your programs) will be important for Exam 1. The following materials contain examples from topics that we have not yet discussed, but the debugging concepts apply to the work that you have done already. Focus on the debugging concepts and not on the specifics of the examples.
1. Watch this video on Debugging: Good Practices to minimize the need for debugging.
  - For reference, here is a PowerPoint slide version of the Good Practices video. If you want to see these slides, download and run this PowerPoint as a Slide Show, since it has animations.
2. Download and run as a Slide Show this PowerPoint presentation on Debugging: What to do when you get a run-time exception (error). Be sure to run this PowerPoint as a Slide Show, since it has animations.
3. Download and run as a Slide Show this PowerPoint presentation on Debugging: What to do when a test fails. Be sure to run this PowerPoint as a Slide Show, since it has animations. This PowerPoint presentation uses an example that is well beyond what you have seen so far; no worries, just concentrate on the debugging principles that it demonstrates.
Pair Programming
- Watch this YouTube video on pair programming. (Note: this link will open in a new tab or window, not inside this window.)
  - The video was developed by the folks at code .org, a terrific site and organization.
  - You will often use Pair Programming in this course, perhaps starting in Session 5.
  - Pair Programming is a real-life technique, per the next item.
- Read this brief explanation of Pair Programming as one of the techniques of Extreme Programming.
- [Optiona] If you want to learn more about pair programming , you might find the following links interesting:
  - Pair Programming as described at the organization Agile Alliance that started a revolution in Software Development in 2001 that persists to this day. You might also enjoy reading the Agile Manifesto that started it all.
  - A study on the effectiveness of Pair Programming
  - Here is the video that popularized Pair Programming in academic settings.
