Run the learning platform
Find where the learning flow slows down.
Nine analysis lenses make different kinds of incomplete, late or unusual work visible.
Admin BI is a separate, admin-only workspace. Staff reporting has its own Overview, Grading and Progress pages.
Started, not finished
A learner started work but has not submitted it.
Inspect the task, available time and next instruction.
The bars are an illustrative visual, not computed analytics. The original page provides metric values, denominators and calculation disclosures from recorded activity.
What this part of Arc does
- No-show runs; started without finishing; late completion
- Stuck tasks, unusual timing, skipped work and repeated retries
- Excellence and early-help signals
- Calculation and input disclosures
This is a browsable portfolio interpretation of Arc’s workflows with fictional examples. Navigation, filtering and theme previews work here; editing, execution and platform services belong to the original application.
Inside the original application.
Real Arc screens and recordings, captured locally with fictional people and work.
Nine ways to notice friction
The native lens cards show signals, denominators and calculation disclosures. Some denominators count learner-run pairs rather than unique learners.
Open the reasoning behind a number
A native calculation dialog explains the no-show definition, threshold, formula and substituted values.
Watch this workflow in Arc
The program behind the classroom.
Explore the original admin and scoped school analytics: inventory, nine friction lenses, an open calculation, modeled indices, a comparison gate and the work behind the numbers.
Read the walkthrough
- Inventory and activity
The original BI view separates all-time inventory from activity within the selected period. Every figure comes from fictional local fixtures.
- Nine friction lenses
Nine distinct lenses show different participation and workflow patterns. Labels and calculation controls remain visible in the original interface.
- Open the calculation
The native No-Show explanation opens. A close-up retains its formula, variables and concrete substitution: one qualifying run out of 25 gives 4%.
- Read modeled indices carefully
The 30-day modeled-index view includes five eligible peers. Its VRI calculation includes a fixed 0.8 assumption; these indices are not validated causal measurements of teaching quality.
- Respect the comparison gate
A separately loaded seven-day slice has no eligible peers. Arc retains absolute values and explicitly withholds a fair peer comparison; this differs from the 30-day view shown before it.
- Review queues and grade context
The scoped school analytics view displays review age, score distribution and a class-by-lesson grade matrix. A detail insert makes the matrix values readable.
- Follow lesson progression
Started, submitted and reviewed counts stay separate along the lesson sequence, followed by a weekly trend view. This is fictional history, not reported live program impact.
