Step 1
Set up the test / Sharpen the mark scheme
You create a test with a title, the class, the type of test (short test, test, school exam, central exam or practice test) and the grading scale. Then you add the questions.
Type them in: for each question the question text, the maximum points and the mark scheme.
With photos: take a photo of the blank test and of the mark scheme. GraidLens prepares the questions and a first mark scheme. That's a draft: check it before you start marking.
From your question bank: reuse questions you made earlier.
The more precise the mark scheme, the better the suggestions. Write it the way you would for a colleague who is marking the test for you.
What do you give points for? Name the criterion for each point.
Which answers are right, half right or wrong? Examples help.
What doesn't count? For example spelling or a missing unit.
Step 2
Upload the students' work
Take photos of each student's work with your phone or a scanner. Several pages per student is fine. GraidLens accepts JPG, PNG, WebP and HEIC (the iPhone default). PDF files aren't supported.
Reading and marking happen in the background. You can do something else in the meantime; for each student you see when the suggestion is ready.
Step 3
Check the suggestions / Approve, export and give feedback
You can check per student or per question. Per student you see the scan on the left and, on the right, for each question what GraidLens read, the score it suggests and why. Per question you see all answers to that question together, with identical answers in a group that you score in one go.
Each suggestion shows how certain GraidLens is. Start with the least certain.
GraidLens checks whether similar answers got a similar score and points out outliers.
You can type feedback for the student or dictate it.
Suggestions with a certainty of 85% or more can be approved together with one button. That is still your action: nothing is ever approved automatically.
Only when you approve a student does the grade count. GraidLens converts the points using the test's grading scale. With 'Adjust grade boundary' you see straight away what a different pass mark would do to the grades.
CSV for Magister or Somtoday (NL): student and grade, ready to import.
Full CSV with the points per question.
A Word document per student with scores and feedback.
A link to the result per student, which you switch on and off yourself.
Test analysis: p-value and item-rest correlation per question, Cronbach's alpha and the measurement error for the whole test.
Try it on your next test.
Create an account, set up a test and let GraidLens mark a few students. The first time, mark them yourself as well and compare.
