Content effectiveness is a measure of how well a specific piece of material achieves its purpose — holding attention and producing learning — assessed per section rather than per course.
What it is
It combines engagement (did this section hold people), learning delta (did knowledge on this section's material improve), and persistence (did people continue past it).
Scoring at section level rather than course level is what makes it useful: a course-level score evaluates the programme, a section-level score identifies the fix.
Why it matters
This is the metric that produces a work order. 'The module scores 3.8/5' starts a debate about whether to keep running it. 'Section 4 scores 0.31 against a course average of 0.72' starts a rewrite.
A common confusion
Effectiveness is not satisfaction. Learners frequently rate easy content highly and demanding content poorly, while the demanding content produces more learning.
