❗PLEASE READ FIRST: You might want to use CLOZE CHEMISTRY instead of this question type. This question type is best for:
When you want students to type in an entire chemistry formula.
When there will be more than one response box that need to work in conjunction with each other.
When there are multiple versions and formats for correct answers.
Does the question you are authoring involve the above component?
If so, then keep reading!
If not, we highly recommend using Cloze Chemistry instead, as it is generally easier to create and score. When in doubt, use Cloze Chemistry!

We recommend reading through this entire article before beginning to build your question, as you'll want to make sure this question type is suited for your intentions. This question type allows students to easily enter chemical formulas, with advanced scoring methods and settings.
In this example, any version/order for the correct answer is accepted.
💡 Tip from the Otus Team: If you need the student to use multiple lines, you may want to use Cloze Chemistry or Chemistry Essay. Chemistry Formula only allows for one line of entry.

Set Correct Answers and Scoring
Step 1: Determine how many points the question will be worth.
Step 2: Type any version of the correct answer in the Value section.
❗ IMPORTANT NOTE: anything that has been entered in the Template field (below the Compose Question field) MUST be entered in the Value field. If the Template field and the Value field do not match, the question will not be scored correctly.
Step 3: Choose a scoring method.
equivLiteral is most commonly used for this question type. See below for more details.
➡️ equivLiteral will only accept the correct answer as written exactly in the Value field. However, if you enable the Ignore order option, the students could type the answer in any order.
➡️ Using equivValue will accept the correct answer in any order (without needing to enable a separate setting like in equivLiteral).
Note - equivSymbolic is not a scoring method used in Chemistry Formula.
💡 Tip from the Otus Team: wondering what the other scoring validations are, such as isUnit and String Match? Check out this Learnosity author guide.
