Week 10 Discussion
Week 10 Discussion
- To me, it seems like it's going pretty well
- I'm not looking for long, involved answers
- A concern was brought up yesterday about people replying non-constructively
- Professionalism is a factor here
Something is fishy...
(Thanks a lot, David - you are kind of undermining the point from the previous slide...)
I think what's happening here is that the "anonymous post" and the "post before viewing" features don't play nice together: it's acting as if you haven't posted because you were anonymous
Course of Action
Preserving anonymity:
- Open the Week 10 Discussion to view by anyone immediately
- Open the Week 10 Discussion to view by anyone, but only after it's locked (April 4th)
- Open the Week 10 Discussion to view by anyone, but turn Moderation on so only approved posts show up
- Do nothing - I don't want lurkers to ever see my post
Answer via anonymous (for realsies) survey on DC Connect
Go to Assessment -> Surveys
Course of Action
- In any case, I won't rush the change
- If people are uncomfortable with what they've posted already being visible (if that's what has been decided) then talk to me and we'll take it down
- In that scenario, I will still consider you to have posted as far as discussion grading is concerned
- At least mechanically, this hasn't worked exactly as I planned and I'm sorry about that
Term Test #2
Question 4
I brought this to Kevin, and the result is...
Chapter 12 Questions
- The chapter 12 questions, which we reviewed Thursday, were still challenging... for example:
Which of the following can you not do with data tips?
- display the values of the members of an object
- display the value of an expression that calls a method
- pin a data tip so it remains displayed until you close it
- add a comment to a data tip
- This was up on the screen and discussed, with the right answer given
- 27.2% of respondents got it right
Question 10
In a multi-tier application, where should validation of business rules reside, and how are valuations of those rules communicated to the end user of such an application?
- I marked this generously, so as long as you didn't say total nonsense for the second part you got 1/2
- Ideally, you would've mentioned the business tier, middle tier, or class level for the first part
- It does say validation of business rules
Randomized Questions
- It shouldn't be a surprise that some questions are somewhat similar and randomized
- This isn't meant to trick you
- ...but it did (for some)
To declare a method or property that can be overridden by a subclass, you use the ______ keyword after the access modifier for the method or property.
To declare a method or property that overrides a method or property in the base class, you use the ______ keyword after the access modifier for the method or property.
Randomized Questions
The process of preventing exceptions from causing runtime errors is called ______ .
To test the Catch blocks in a Try...Catch statement, you could code ______ statements.
When an error occurs during the execution of a method, the method ______ an exception.
To test whether a text box entry has a valid Decimal format and provide feedback to the user/developer using the Convert.ToDecimal method, you need to use a ______ statement.
One Question Had a Problem
- I am aware of a significant problem with some of the Chapter 7 code example-related questions
- It would be right near the end of the test
- Most people got it right anyway, but there was another interpretation that is sort of reasonable
- I looked, and I think there are only 3 people this may have affected (I know who they are)
- Tell me why you picked what you did and you might get the mark
A Note for Term Test #3
- Chapters 8 and 18 are part of Term Test #3 (as well as Chapter 24)
- Some Chapter 8 questions were already on Term Test #1
- Some Chapter 18 questions were already on Term Test #2
Lab 3B
Due Friday, March 20th
Before You Submit
- Read your Lab 2B feedback
- Read the requirements
- Read the rubric
- Read the Style Guide
- View the "Lab 3B Walkthrough" video - based on last year's Lab 3B but they're essentially identical
Lab 2B -> Lab 3B
- Lab 3B is closely based on Lab 2B
- You should have a perfectly working Lab 2B before you start
- You'll have done a fair amount of the work toward Lab 3B just by doing Lab 2B
- Check your Lab 2B feedback
Lab 2B -> Lab 3B
The big things that Lab 3B adds from Lab 2B are:
- Senior Pieceworkers
- Access specifiers
- Exception handling
- Events
These are what contributes to the Lab Specific Concepts & Implementation part of the rubric.
Lab 2B -> Lab 3B
Another thing is the improvements to the validation. Validation is a part of IPO, contributing to the Input, Processing and Output part of the rubric.
- Correct validation
- Correct calculations
- Display is formatted properly
- No crashing
- Treat types correctly (Option Strict?)
Lab 2B -> Lab 3B
Otherwise, your feedback from Lab 2B should address most of what could possibly be wrong.
Lab 4
Due Wednesday, April 8th
Lab 4
- I quietly changed all the due dates
- People who can manage time well ought to just use the old dates, though
- It's consultation-based, but it's a GUI application
- Choose your own partners, as usual (survey)
- We'll talk more about this next week
Drop With a "W"
Wouldn't that be "Wrop"?
What's "Wrop"?
It's Not Wrop
- Friday is the day when you can drop a course and not have the grade show on your transcript
- If you're having trouble managing your courses (this, or another one) you may need to work our priorities
- Tomorrow would probably be the last good day to do that
- Don't panic: nearly everyone who is in class on a regular basis is doing well
