Create partial scoring when units are missing

In this tutorial, you will extend a right-triangle question to accept answers without units, assigning them partial credit instead of marking them as fully incorrect.

Outcome: By the end of this tutorial, your question will award a full score when the answer includes units and award a partial score when the units are missing.

Before you begin

Prerequisites

• You should be familiar with basic right-triangle geometry.
• You should have completed Create a randomized right-triangle question with tolerance.

Requirements

• A teacher account with permission to create questions in LearningLemur, accessed through learninglemur.com or your LMS.
• A question that computes the hypotenuse using a random expression with units of measure enabled.

Steps

Step 0 — Open your existing question

Why: You will extend an existing question instead of creating a new one.

1. Open your quiz.
2. Select the question created in the previous tutorial.

Checkpoint: The question editor is open with a correct answer defined using #sol cm.

Step 1 — Add an answer without units

Why: LearningLemur allows multiple valid answers with different scores.

1. In the Answers section, click Add answer.
2. Enter the expression without units #sol
3. Set the score for this answer to 50% (or any other value lower than 100%).
4. Choose how the tolerance is applied.

Checkpoint: A second answer appears in the Answers section with a score lower than 100%.

Step 2 — Add feedback for missing units

Why: Providing specific feedback helps students understand why their answer is only partially correct..

1. In the Answers section, click Customized feedback for this answer under the answer without units (#sol).
2. Write the feedback message.

Checkpoint: When submitting an answer without units, the feedback message is displayed to the student.

Step 3 — Preview the question

Why: Previewing allows you to verify how different answers are graded.

1. Click Preview question.
2. Try entering several answers, such as:
   1. the exact value (if available) with units of measure.
   2. a rounded value with units of measure.
   3. the exact value (if available) without units of measure.
   4. a rounded value with units of measure.
3. Verify that correct answers are accepted, and answers without units receive a partial grade.

Checkpoint: Answers with units receive full credit, while answers without units receive partial credit.

You're done

You have extended your question to support multiple valid answers with different scores. You learned how to:

• Define multiple answers for the same question.
• Assign different scores to each answer.
• Handle missing units using partial credit.

Troubleshooting

Answers without units are marked as incorrect.
Check that:

• A second answer (#sol) is defined.
• The answer is assigned a non-zero score.
• The evaluation option is set to Mathematically equal, not Literally equal.

All answers receive the same score.
Check that:

• Each answer has a different score assigned.
• The correct answer with units is set to 100%.

Answers with units are not recognized.
Check that:

• The required unit is enabled in Units of measure.
• The required prefix is enabled in Unit prefixes.
