Landing page captured for the 2026-09-07 issue.

Field notes

Nybble organizes its material around exam-shaped activities rather than a generic quiz format: students can reorder Parsons code, complete trace tables, answer binary and hexadecimal questions, and run Python through PRIMM-style exercises. The page lists 582 questions and problems, including 160 Parsons problems, 67 trace tables, 286 multiple-choice questions, and 16 PRIMM sequences. Its distinctive record is misconception tracking: tagged distractors are aggregated once per student and ranked for the teacher.
