stringMatch Scoring Method

Overview

The stringMatch method is used for literal string comparison. This compares the value set by authors in validation against a student's response, and evaluates if the two values are the same. stringMatch is a simple comparison method, and it does not take the syntax and data type set in the validation area into account.

Additional Options

  • Ignore leading and trailing spaces
    Ignores spaces before and after a value, i.e. " a " will be treated as "a".

  • Treat multiple spaces as one
    Multiple spaces will be ignored and treated as one, i.e. "a   b" is the same as "a b".
  • Inverse result
    This will invert the response specified in validation. This means that any response will be correct except for the one set by the author. 

Examples

Example 1 - Ignore leading and trailing spaces + Treat multiple spaces as one

The student's response should match the exact value set in validation. Ignore leading and trailing spaces and Treat multiple spaces as one are enabled.
