Playback student code as it was written

Codio’s Code Playback enables instructors to understand their students’ thought processes by replaying student code creation as it was written from beginning to end. See students’ implementation of learned concepts, review student input across multiple files, visualize and identify pastes, determine areas where students encounter difficulties, grade students’ effort, and highlight potential cases of plagiarism.

Playback code and pastes across multiple files

Codio's Code Playback functionality supports multiple files, illustrating how students navigate between various files during programming. Code Playback also reveals pasted code. By clicking on a marked paste, it becomes visible on the timeline highlighted in green and appears within the context of the code file in the upper pane. Navigate the timeline by either playing the player, dragging the timeline itself, or utilizing the zoom buttons.


Frequently Asked Questions

What is code playback?

Code playback is a feature that allows instructors to view the steps learners take when learning how to write code. This feature is handy if users want to examine how learners approach solving problems when learning how to program. Code playback helps instructors to gain insights into a learner’s thought process for better grading.

It also enables them to grade the coding process more accurately. The Code playback tool shows students how to use code. Instructors can see whether or not learners are following best practices with the chosen programming language.

Can Codio see if you copy and paste?

Yes, Codio can see if learners copy and paste work. Code playback shows the step-by-step process, which includes insertions of large chunks of code. This would typically indicate copying and pasting from another source.

Instructors should normally see lines of code appearing as learners gradually solve a problem using code. Plagiarism detection is built into Codio, meaning instructors can see if learners copy from other sources.

How do I open the terminal in Codio?

Learners can open a terminal in Codio by going to the menu bar and clicking Tools → Terminal. They can also access the terminal using the Filetree by clicking the Terminal icon in the upper menu bar. Codio allows users to open multiple terminals conveniently when learning how to program. Users can create many panels and tabs for an efficient workflow when they learn to code.
