Learnosity Math auto-scores Questions using different scoring methods. Our methods fall into two categories: evaluation types and form checking.
Evaluation type methods compare the learner's response against a sample correct answer set by the author in differing ways. These are the most common scoring methods used in Question validation.
With form checking methods the author does not set a sample correct answer for comparison but rather the methods check whether the learner response meets some specific condition.
Our scoring methods can be used alone or you can combine methods for more thorough validation. This typically involves combining an evaluation type like Numerically equal to (equivValue) with a form checking method like Formatted as (equivSyntax).
Evaluation Types
Literally equal to (equivLiteral)
Checks that the learner response and the answer set by the author are equivalent and in the same form. This is the default method.
Symbolically equal to (equivSymbolic)
Checks that the learner response and the answer set by the author are symbolically equivalent even if they are in different forms.
Numerically equal to (equivValue)
Checks that the learner response value and the value set by the author are numerically equivalent - differs from equivSymoblic because it can be used with units of measurement and does not work with variables.
Exactly matched to (stringMatch)
Checks that the learner response is an exact match to the author's sample answer - doesn't use the math scoring engine.
Form Checking
Checks that the learner response matches a specific form set by the author, for example written as a fraction or a decimal value with a specific number of decimal places.
Checks that the learner response is true; this is mainly used for equations and inequalities.
