Buzz: Questions & Answers

Fill in the blank questions not grading correctly

I am using a normal fill in the blank to have students enter inequalities. It seemed to work well, but lately, it will mark the question incorrect when it is correct. The weird thing is that I have it marked to display the correct answer, and it will not display the correct answer when I put in the correct answer but it still marks it as incorrect. If I enter an incorrect answer, then it displays the correct answer. This makes me think that it is recognizing the answer as correct but for some reason is not counting it. I have screenshots of what is happening if that would help.

I use inequalities in my algebra course. Maybe I can help. Can you post a screenshot or copy/paste the code for the question?

Here is an example of when I enter the answer correctly and it marks the question incorrect:

Here is an example of when I answer incorrectly and it then shows the correct answer in parenthesis.This makes me think that it is recognizing the correct answer for the first screenshot but considering it incorrect for some reason.  Any insights would be much appreciated.

Here is the code:

The problem is that Buzz doesn't support the eval function in the answer for a normal answer type. You can only have eval answers in number, math exact, and math equivalent. As you probably know, you can't use equations or inequalities with any of those answer types though. One way we get around that is to use 3 answer blanks.

___  ___  ___ and the students fill in  _x_   _>_   _4_

You can also move the eval from the answer to the question and have the answer be just the variable. You could do this, for example.

Solve the following inequality: `$a$ + x > $eval($a$+$b$,0)`

a. $b$

Note that one disadvantage of the 3 answer blank option is that you can't put your alternate answer. When we do that we have to include a note for students to put the variable in the first blank. Or we sometimes put the variable in with 2 answer blanks after for the symbol and the number.

Bruce,

Thank you for your help!  I was not aware that the eval function was not supported as an answer type.  I appreciate your examples and will fix the questions that are not working!
