Instructional feedback is the response a learner receives after taking action in a learning activity — communicating whether the action was correct, why, and what happens as a result.
Feedback is where teaching happens. Until a learner acts, there is nothing to respond to. The quality of feedback after an authentic activity determines whether the learner grows from the experience or just moves on. Content teaches what — feedback teaches whether and why.
A stakeholder review is a structured meeting or async process in which the instructional designer presents a storyboard or course draft to stakeholders and subject matter experts to gather feedback, validate decisions, and gain approval before proceeding to the next development stage.
A reviewed and approved storyboard is the primary defence against late-stage changes and scope creep. Feedback collected before development begins costs almost nothing to act on. Feedback collected after a course is built can cost everything. The stakeholder review is where that early feedback is systematically gathered.
