labeled_ans_rule
DescriptionThis enters an answer rule attached to a specific label. This allows more control when matching student answers with answer evaluators
Syntax
labeled_ans_rule(label,width)Params
The first parameter is the label and is required.
The second parameter is the width of the ans_rule and defaults to 20 (characters) if omitted.
Returns
The HTML (or TeX) code for an answer blank.
Examples
BEGIN_TEXTComplete the sentence. Hello \{labeled_ans_rule("string_answer",20)\}
4+8 = \{labeled_ans_rule("numerical_answer"\}
END_TEXT
LABELED_ANS("numerical_answer" => num_cmp(12),"string_answer" => str_cmp("World") );
checks that the first answer is "World" and that the second answer is numerically equivalent to 12, despite entering the answer evaluators in an order which does not match the appearance of the answer blanks.
Notes
This is essentially syntactic sugar for "NAMED_ANS_RULE". It provides a default for the width, andlabeled_ans_ruleseems a more descriptive title thannamed_answer_rule. The low level (capitalized) subroutines will retain the titles NAMED... for backward compatibility.
The labeled (or NAMED) versions of answer blanks and answer evaluators can be useful in situations where the order of the answer blanks is not obvious.
