Brian Scarbeau Insights from a seasoned Computer Science Trainer

My friend Dan Forhan who teaches at St. Peter Marian HS in Worcester MA is blogging about teaching oop.

Here's what the students need help on according to a report from the Chief Reader David Reed:

 

students did reasonably well, some confusion on OOP concepts

?? common error: not understanding class vs. interface

e.g., interface definition with instance variables and constructor

e.g., Set s = new Set(); instead of Set s = new HashSet();

?? common error: not recognizing when inherited data/methods could be used

e.g., overriding parent class instance variables & methods, failure to call super

You can help your students if you review these concepts with them.
