-Adaptive or conditional hints in LON-CAPA
-Note: an extra space has been added before each tag closure in any tags included below so that the text will be displayed correctly by the FAQ-O-Matic.
-
-Hints are placed within <hintgroup ></hintgroup > tags. The first part of the hint is the condition, which includes a specification of the foil(s) and foil answer(s) required to trigger the hint. The answers specified in the hint condition are compared with the user's submission, and if the condition is met, the hint action included in the conditional hint block will be executed (for example this could be the display of a block of text). You can set multiple hint conditions for a particular problem. Hint conditions are identified by a name. The corresponding hint action includes this hint condition name in the "on" parameter). When a hint condition evaluates to true, the corresponding hint action is triggered. Besides providing hint actions within <hintpart on="NAME" ></hintpart > tags for each named (NAME) hint condition, a hint can be designated for display if none of the conditional hints evaluate to true. The default hint is not displayed if the conditions were met for !
any of the conditional hints. The default hint action is included between <hintpart on="default" ></hintpart > tags.
+Hints are placed within \textless hintgroup \textgreater \textless \textbackslash hintgroup\textgreater tags.

nal hints evaluate to true. The default hint is not displayed if the conditions were met for any of the conditional hints. The default hint action is included between \textless hintpart on="default" \textgreater\textless /hintpart \textgreater tags.
There are five types of hint condition:

-Formula Hint condition
-Numerical Hint condition
-Option Response Hint condition
-String Hint condition
-
-The syntax used to describe the foil(s) and the foil answer(s) differ for the five types:
-1. Formula Hint condition
-The formulahint tag takes three parameters: answer, name, and samples. The "name" is the unique name given to the hint condition. The formula answer for which you wish to provide conditional is included in the answer parameter. The samples parameter includes the points (or range of points) over which sampling of the student's submitted answer and the formula included in the formula hint answer parameter are to be compared. The syntax is the same as used to specify sampling points in the samples parameter of the formula reponse tag itself. The formula submitted by the student is evaluated at the sample points for the hint and the calculated values are compared with the corresponding values determined by evaluating the "hint" answer at the same sampling points. A close correspondence between the two sets of values will trigger the hint action specified in the <hintpart > tag.

-3. Option Response Hint condition
-There are two types of option response hint conditions: one for standalone foils and one for concept groups. In both cases the option hint tag includes two parameters: answer and name for standalone foils, and concept and name for foils grouped together in a concept group. For the answer parameter, the names and submitted values for each of the foils that are being included in the hint condition are provided in a hash, i.e., in the format: ('Foil1'=>'True','Foil2'=>'False'). In the case of a conditional hint for a concept group, the format of the concept parameter is also a hash that links the name of each concept group included in the hint condition to either 'correct' or 'incorrect' - e.g., <optionhint concept="('buoyancy'=>'correct','density'=>'correct')" name="fluids" / > If 'correct' is specified for a named concept then when the conditional hint is evaluated answers for each of the foils selected by a student must be correct for the hint action to be triggered. If any!
thing other than 'correct' is provided in the concept hash in the optionhint tag then then students answers will be compared with the set answers for the foils in the concept group and as long as at least one answer is incorrect (i.e., the concept group was not correctly answered) then the corresponding hint action will be triggered.
