Misconception: students forget about language-specific or paradigm-specific material (e.g., new/delete or types) when they switch between languages that don’t use the same concepts.

Like 
  • Remind students when they switch languages about language features that weren’t necessary in their last language (e.g. delete isn’t necessary or possible in Java).
    • This also applies for returning to a language previously covered, like returning to C++ after working in python and forgetting typed variables.
  • Students going from Java back to C/C++ might forget how to initialize arrays.
    • In Java students could write:
      • int [] numbers = new int [10];
    • But in C++ they have to write:
      • int numbers[10];
  • Students going from Python back to Java might forget that they need type declarations.
    • In Python they could write
      • x = 3;
    • but in Java they would need to write
      • int x = 3;
      • It is really common to forget the type declaration!
