MATLAB Grader is a browser-based authoring environment for creating and sharing MATLAB coding problems and assessments.
Why Use It?
MATLAB Grader allows for students to be provided with interactive course problems and assessments with automated grading and feedback. These can be script or function-based with simple correct/incorrect or weighted marking. These scores are then passed back into Moodle as a percentage, which is represented in the gradebook as a value between 0 and 100.
The video below provides a good overview for MATLAB Grader and its features. The content after 2:29 mins is not relevant for UCL users using the MATLAB grader integration with Moodle, it is only relevant for users using MATLAB Grader directly.
Who Can Use It?
Tutors can set up coding problems and assessments for students to complete.
Students can complete coding problems and assessments set up by their course tutors.
Before I Start...
Consider how a problem or assessment created within MATLAB Grader fits into your course.
Is the problem text clear to students?
Will students know how to input their answer?
Do I want students to solve everything correctly, or have a weighted score based on what they get correct?
4.1 Provide an assessment outline with a clear description of the module assessment, including schedule, criteria and submission details. To avoid duplication this might include a link to a module webpage.
How Do I Set One Up?
The steps below provide an overview of the process, but has links to MATLAB Grader documentation for information on writing MATLAB code.
Step 1: Add a MATLAB Grader Link
Navigate to your Moodle course and switch Edit mode on.
Click Add an activity or resource in the desired section of your course.
Select MATLAB Grader, then click Add.
Set an Activity name.
You can also configure the following options:
Grade to pass can be used to set a passing grade. Please note the grade shown in Moodle is a percentage and the Maximum grade should be left at 100.
Completion tracking can be set to Show activity as complete when conditions are met to automatically mark the activity complete when students view the activity, receive a grade, receive a passing grade, or all of these.
Click Save and display.
Then click Open in new window.
Step 2: Create Your MATLAB Grader Assessment
To create your assessment, click onto Blank Problem.
You can use LMS Courses to copy existing problems from your other courses if you've created some already.
MATLAB Grader also provides some example problems that you can review and copy.
Enter a Title for your problem. It's recommended that this name matches the name of the activity within your Moodle course as both names will show to your students.
Enter a Problem Description and Instructions, which can include formatted text, equations, links and images.
Files Referenced can be used to upload data and code files for use in the reference solution, learner solution and assessment tests.
Problem Type is used to determine how you want students to implement the solution.
