- Students may be able to repeat given explanations of concepts without fundamentally understanding them. For example, a student may be able to say that a variable is like a box, but may still not be able to use variables successfully.
- Walk-throughs are very helpful for checking how well students understand state. Students should be able to articulate the state of variables/objects (i.e., the values of variables or private data members/object attributes) as they move through the code.
