CheckiO is special because it offers fun coding challenges, tools to solve puzzles, and unique solutions shared by users. But for teachers, we offer something extra:
Support
If you're a teacher or mentor, use CheckiO Classrooms to create student groups, assign tasks, track progress, and give feedback.
Privacy
You can control your students' visibility outside your Classroom. Decide if their profiles, solutions, and comments will be visible to other CheckiO users.
Activity
You can track your class's activity, leave private comments on solutions, and view the history of code changes.
PROGRESS AND SHARE
Progress
Class Progress gives you a clear table showing all your students, their last activity time, and the missions they’ve solved or attempted but didn’t finish.
Solutions you haven’t reviewed are highlighted in the table, and you can filter by new solutions.
Tried, but Need Your Help
You can view unfinished solutions, check the history of changes, and even join a pair coding session if the student is currently online.
View Progress of students in Real Time
See if any students are on the mission page. Watch their thought process and offer help if needed through online Pair Coding.
