Students Learn About:

• Commonly executed sections of code
  • reusable code
    • standard logic, such as:
      • a login process
      • data validation
      • conversion between date formats
    • to replace multiple occurrences of the same code
  • combining code from different sources
    • copying and pasting into code
    • calling modules or subroutines
  • making the same data available to different modules 
  • global variables
  • parameter passing
  • use of functions and procedures

Students Learn To:

• develop standard modules or subroutines for reuse
  
  
• create solutions to problems using existing code with minimal change or additions
  
  
• develop code that makes use of common modules or subroutines
  
  
• differentiate between the scope of local and global variables
  
  
• develop code that makes appropriate use of global and local variables
  
  
• develop code that calls common modules and passes parameters appropriately
  
  
• incorporate functions into modules or subroutines
  
  
• make use of procedures (see Course Specifications document)
• (see Section 7 of Course Specification for sample algorithm fragment)
