How do I create Working Formula questions?
Working Formula questions are often used in Maths, Chemistry and Physics. It is a question component for advanced formula writing. Students need to write something that matches one of the steps you have written in order to get a tick or be marked correct.
To create a question containing a Working Formula component, add an Extended Response question and select the Blank slide option.
From there, drag over the Working Formula component.
In the new window that opens you can write the starting formula in the gap under Add explanation. You can add additional steps by pressing enter or the New step option.
Ticking the Marked option will select that working to be marked for the student attempt. You can select multiple steps to require marking.
Students will need to get all of the steps that have been ticked Marked correct before they are able to move on to the next question.
If there are multiple ways to solve the formula, you can add an additional method by selecting the New method option.
Different methods will have different answers. You will need to ensure that these match up.
You are also able to add variations to the steps using the New step variation option. These variations are counted as the equivalent or same step. To make this option available you will need to select Advanced.
Your students' answers will have to match one of these variations. It is best to add as many variations as possible to account for the different lines of thinking for your students.
Any variations with multiple = symbols will not work.
Since the Working Formula process is complex, it is always best to preview the questions before you pass the lesson on to your students. This will help ensure that there are no unexpected complications to the question.
EP Studio also includes parameters that help make the Woking Formula questions smarter. These parameters are commands for the question to process before checking whether the given answer is correct or not. Hovering over each parameter will reveal the underlying LaTeX representation of the working.
It is recommended that you have a demo with one of our Teacher Consultants before using parameters in your questions.
