Student's answer throughout a question

An interesting Wiris Quizzes' feature is the possibility of using the student's answer throughout the question. In other words, you can now give a personalized grading or response to each student, depending on what their answer was, with several purposes.

The main purpose when using this feature is to compare the student's answer with the correct one. Let's ask the following question:

You can add dynamic feedback to the question, that changes based on the student's answer. For example, in this question you could be interested in graphing the student's answer, and compare it to the correct answer:

To do so, you just have to write parameter answer = 0 in your CalcMe algorithm and, from then on, the student answer will be stored in a variable called answer. For the feedback example you just looked at, you must end up with this:

Finally, you have to add an answer blank for the wrong answers and use the customized feedback for it.

If you don't know how to do add a second answer, see the following documentation page.

Another purpose of using this feature is to provide the student with the steps they should have followed to answer the question correctly. Let's ask the following question:

You can add dynamic feedback to the question that changes based on the student's answer. For example, in this question, you could show the procedure the student has to follow to answer the question correctly. Moreover, you can also show why the provided answer is not appropriate.

To do so, as in the previous example, you have to write parameter answer = 0 in your CalcMe algorithm and, from then on, the student answer will be stored in a variable called answer. For the customized feedback example you just looked at, you will need to access the two answers given by the student and calculate the value of the polynomial in those points. The algorithm must end up with this:

Then, you have to add an answer blank for the wrong answers and use the customized feedback for it. Keep an eye on the used notation!

Finally, you have to add the general feedback showing the procedure to solve the problem.

Another feature approach is the possibility to use the student's answer in a later part of the question. For instance, imagine you want to ask the following question:

If a student gets the original line wrong, you may be interested in providing a partial grade if he uses the wrong answer correctly to get the perpendicular gradient. To do so, you need to create a grading function. The CalcMe algorithm must be something as follows:

To learn more about grading functions, see its dedicated page.

Thus, perpendicular lines passing through the corresponding point will be accepted even though the original line didn't match the initial requirements.
