A field of letters appears very briefly; afterwards an arrow shows which row to enter
This is a solo practice run: your results stay in this browser tab and are never sent anywhere. To contribute to a class result, join a live session with a code instead.
This task is new to Classperiment and has not yet been fully tested. Issues may occur in the procedure or scoring. The expected effect may also fail to appear reliably.
Task time: 4–5 min; slow up to about 8
Look at the middle. In a moment a field with three rows will appear very briefly. Remember as much as you can from the whole field. Only afterwards does an arrow show which row you should report. Enter its four letters from left to right. If you do not know one, choose “Don’t know”. Confirm your row; you have up to 8 seconds for this.
Tap or click the letters on the letter pad, or type them on the keyboard: ? stands for “Don’t know”, Backspace deletes, Enter confirms. Tap a position to correct it.
First, three examples in which the field stays visible, then 6 practice trials. In a classroom session, the explanation and results appear after the instructor releases them.
