Below you see a list of all evaluation types that can be used for text-based answers.
Checks whether the user input contains all the texts from the Definition field, not necessarily in the same order. The texts must be separated by a semicolon ';'. Variations of the same text (e.g. contractions) can also be added by placing them between square brackets '[ ]' and separating them by comma ','.
For example, if Definition: [is not,isn't];and;tree then the user input must include the texts 'and', 'tree' and one of the words 'is not' or 'isn't' in order to be considered correct.
Note that the text “a band is not the same as two trees” will also be correct because both 'and' and 'tree' are included (in the words ‘band’ and ‘trees’).
Same as “Contains text”, but now “a band is not the same as two trees” will not be considered correct, because “band” is not the same word as “and”, and “trees” is not the same word as “tree”.
Determine a percentage of similarity between the student's answer and the solution Definition, for example to catch spelling errors. Specify a Precision to set the tolerated percentage deviation between the student’s answer and the Definiton, e.g. Precision = 10 would mean there needs to be a 90% similarity in order to evaluate to ‘true’.
The similarity between “parabol” and “parabola” is ⅞=87,5%. The Precision is 20%, which means a similarity of 80% would suffice to activate this feedback rule:
Text case insensitive
Checks whether the user input is equal to the text in the Definition field with a case insensitive check.
Text case sensitive
Checks whether the user input is equal to the text in the Definition field with a case sensitive check.
Checks whether the user input matches the regex pattern entered in the Definition field. For more information on regex patterns, click here.
For example, if you want to write a regular expression to match a date format such as dd/mm/yyyy then you would write the following:
Note that we need to escape the forward slashes with a backslash.
Any html-tags are stripped from the student's answer, so usage of bold tags like “The answer is <strong>apple</strong>” will become “The answer is apple”.
Default incorrect (only in Negative feedback)
Always reacts to wrong answers and has a predefined priority of 99.
