Only selected learner examples in this classroom scope are shown here.

Native reports also show queue-age buckets, review time, revision requests, grade distributions and a class-by-lesson grade heatmap. Those metrics need version, grade and timestamp data beyond this small sample.

What this part of Arc does
  • Pending, graded, feedback coverage, review time, overdue and revision metrics
  • Queue-age buckets and grade distribution
  • Class-by-lesson heatmap, task-type grades and review priority queue
  • Program, school, class, instructor, lesson, task type and period filters

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.

Understand the review workload

Queue age, grade distribution and a class-by-lesson heatmap show different parts of the feedback pipeline.

IN MOTION

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.

  1. Inventory and activity

    The original BI view separates all-time inventory from activity within the selected period. Every figure comes from fictional local fixtures.

  2. Nine friction lenses

    Nine distinct lenses show different participation and workflow patterns. Labels and calculation controls remain visible in the original interface.

  3. 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%.

  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.

  5. 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.

  6. 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.

  7. 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.
