Nybble
0100 1110An activity portal for Leaving Certificate Computer Science.
Quizzes, number bases, Parsons problems, written answers and Python in the browser — set to a class or an individual, marked automatically where it can be, reviewed by a teacher where it can’t.
Try an activity
Binary & hex
Generated from a seed, so every student gets a different paper.
Parsons problem
Reorder the lines and set the indentation. Two lines do not belong.
Multiple choice
Code in the stem, single or multiple answers, marked-up review.
DemoThese are real activities, but marked in your browser and not saved — no sign-in needed. There is also a developer harness that shows every message crossing the sandbox boundary.
What it does
Set work to a class or one student
Assignments carry a due date and an attempt limit. A student sees only what is set to them, enforced in the database rather than in the page that draws the list.
Marked before the student leaves the page
Multiple choice, number bases and Parsons problems are marked server-side, by the one piece of code that is allowed to read an answer key. The browser never sees it.
A review queue for everything a machine cannot mark
Written answers and open-ended code land in front of the teacher with a mark box per step, the student’s work replayed beside it, and marks released when you choose.
Five kinds of activity, and a contract for the sixth
Multiple choice, binary and hex, Parsons problems, written answers, and real Python running in the browser. A new type is an HTML file and a database row — no portal redeploy.
PRIMM sequences, start to finish
Predict, Run, Investigate, Modify, Make as one five-step activity. Each phase is weighted and marked in the way that suits it, and Investigate quotes the student’s own prediction back at them.
Installable on a phone or Chromebook
Add it to the home screen and it opens like an app. Activities still need a connection: an install a teacher believes works offline is worse than no install at all.
