The Chemistry essay with rich text question type allows learners to input text and chemistry formula within the same response. This allows learners to describe chemistry concepts and display chemical formula or equations relevant to their work.

Chemical formula and equations can be inserted into the text via the add formula toolwhich will open the formula keypad when selected. learners can then edit the inserted formula by clicking on it to re-open the keypad. The keypad and the symbols available to the learner can be configured by the author, see Keypad in the More Options section below.

This Question type is manually scored. Learner responses must be reviewed and scored by a teacher.

As the score is assigned through human judgment, there is no automatic scoring configuration available for this Question type. You cannot define correct answers or scoring rules during Question setup.

Scores are applied after submission as part of the manual grading workflow. Teachers evaluate the response using their own criteria, and the score is recorded via Learnosity’s manual grading workflow.

For more information about manual grading in Learnosity, see What is the Grading API?
