Submission Review Service

Being able to report a score to the platform's gradebook has long been a key feature of the Learning Tools Interoperability (LTI) specifications. It started years ago with the LTI 1.1 basic outcome service, and is being significantly enriched by the newer Assignment and Grade Services. For example, the Assignment and Grade Services allows the tool to notify the platform that an activity has been submitted and now needs grading. However, once in the gradebook, there is no easy way for the instructor or the student to go back to the tool to see what's 'behind' the grade or the needs grading flag, and eventually grade the learner's work. This is the purpose of this message: launch back from the platform's gradebook to the tool to display the learner's submission for a particular line item. The term submission in this specification refers to any representation of the learner's work; that representation can greatly vary based on the type of activity. For example, a submission can be your traditional essay the learner wrote for a writing assignment, or some statistics about the user's engagement in a group online game session that took place earlier.
