The syntax used to describe the foil(s) and the foil answer(s) differ for the five types: |
| 1. Formula Hint condition |
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 anything 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. |
