How it works

Curriculum alignment checks whether the activities students actually do add up to the standards they're supposed to meet. This is a simplified version of Webb's Alignment Analysis, the methodology school systems use to audit whether instruction matches state/national standards, scored on four dimensions:

Categorical Concurrence (CC)
  = (# standards with ≥1 linked activity) / (# standards)

DOK Consistency (DC)
  = (# links where activity DOK ≥ standard DOK) / (# links)

Range Correspondence (RC)
  = (# standards whose linked activities span
     ≥2 DOK levels, or meet/exceed the target) / (# standards)

Balance Index
  = 1 − Var(links per standard) / (mean² + 1)

Depth of Knowledge (Webb, 1997) ranks the cognitive demand of a task on 4 levels: 1 Recall, 2 Skill/Concept, 3 Strategic Thinking, 4 Extended Thinking. A standard is only well-aligned if activities not only exist for it, but ask students to think at least as hard as the standard requires — that's what DOK Consistency checks, separately from mere coverage.

Alignment matrix — click a cell to link/unlink a standard (row) to an activity (column); green = the linked activity meets or exceeds that standard's DOK, red = it under-shoots it.
Activity + DOK slider — raise or lower how cognitively demanding one activity is; every link involving it re-scores instantly.
Auto-Align — greedily links each standard to the closest-matching unused activity by DOK level, showing what a well-aligned curriculum looks like.
