Sessions

A session is the store for all information related to a single student working on a single exercise or question. It contains the definition of the exercise, all actions of the student, and all information generated by Algebrakit (hints, evaluation results, feedback, and scoring).

Each session has a unique session ID, which is returned by the Algebrakit web service when calling /session/create. Use this session ID to:

• Restore the exercise or interaction web component. For example, the web component is restored to its most recent state when a student navigates away from the page and returns to it later.
• Review the question. Reconstruct the question web component such that a teacher can inspect all intermediate results, feedback, and hints.
• Get the worked solution for a session.
• Get a list of all learning events. Obtain a list of evaluation results, detected student errors, and generated hints.

Notes:

• A session does not store any information that identifies the student.
• Session objects are automatically deleted one year after they were last accessed.
