Important notes about required keywords

1. To re-emphasize, required keywords are different from Short Answer questions because in Short Answer questions, as long as students have just one of the acceptable answers, then it is marked as correct. For Free Response required keywords, students must have ALL of the required keywords.

2. Required keywords ARE NOT case-sensitive. If you put "hydrogen" as the required keyword, and your student puts "Hydrogen", that will be counted as correct.

3. IMPORTANT: The underlying required keyword-checking logic simply looks for the existence of the word in the answer. This ends up having some important implications when deciding what to use as the keyword. For example, if you put that a required keyword is "molecules", but the student puts an answer that says "the answer is molecule", then this answer will be marked as incorrect because the word "molecules" is not technically in the answer. However, if you put that the required is "molecule", but the student writes "the answer is molecules", then this would be marked as valid because the word "molecule" is technically in that answer.

“The keyword doesn't actually need to be a word. I wanted “volcano” to appear in the answer, but realized that students could write “volcanic”, so I just made "volcan" the keyword, which will catch both answers”
