CDLA · Module 4 — Pathway and blend architecture
A micro unit stands alone, serves one action and is the right length for a moment. A chopped long course is not microlearning.

01
Sponsors say "make it micro" and often mean "cut every module into five-minute pieces". That is chunking. Segmenting helps inside a lesson, but it is not microlearning. A micro unit is a standalone experience: it opens a need, teaches or rehearses one action, and closes with something usable, without the previous twenty screens.
02
True micro unit: Makes sense opened on its own, from search. · One action, one decision or lookup. · Ends with a usable output: a decision, a checklist, a script.
Chunk of a long course: As we saw in Part 3. · A slice of a topic. · Ends with "Continue to Part 5
03
Program: Branch manager onboarding.
Capability: Run a compliant cash close.
Action: Reconcile a discrepancy above SAR 200.
Moment: At the safe, end of day, under time pressure. That moment is pull, so the unit is a 3-minute decision aid with one worked case.
04
Do not start with "we need a reel, a podcast, a chatbot". Start with the action and the moment: push, pull or practice. Length is a constraint, not a goal. A three-minute video that covers seven topics is still a bad course, just shorter.
05
Use micro when | Do not use micro when
Reinforcing after a full rehearsal (spaced pull) | First teaching of a complex multi-step skill
A decision or lookup at the desk | The only goal is "shorter compliance"
One exception learners miss under pressure | The action depends on prerequisites from a longer arc

The most cited study on video length is Guo, Kim and Rubin's 2014 analysis of 6.9 million video sessions in edX courses. Median engagement time was at most about six minutes whatever the video's length, and engagement fell as videos got longer. Two cautions. Engagement is not learning: the study measured watching, not performance. And the learners were MOOC students choosing to watch, not employees assigned a course. Use it as a reason to segment and to cut filler, not as proof that six minutes is the ideal length for everything.
