Meaning first, placement second
A lesson is a place for presenting ideas; a skill identifies an action or capability to which evidence can relate. A unit title does not define that capability, and country or grade are not necessary parts of every skill’s meaning. They describe its teaching context.
Warda separates identity from placements in particular editions and lessons. One lesson may introduce a skill, another develop it and another revisit it. These roles are more precise than assigning a skill to one lesson and duplicating it under new names in other books.
Similarity does not establish equivalence
Similar titles do not justify merging skills. The required action or context of application can differ. Curriculum alignment needs a stable definition, context and reviewed relationships rather than unrestricted inference from names.
Changing the meaning of an already-used definition should not silently preserve its old identity as if earlier evidence measured the new definition. Continuity depends on keeping the meaning of recorded attempts understandable. Renaming and changing the underlying capability are different operations.
Two relationships answer different questions
A prerequisite describes educational dependence: an idea needed to understand or perform another. A related-concept link describes a connection without necessarily imposing order. Conflating them turns every possible connection into a barrier for the learner.
Their rules differ accordingly. Dependence needs direction and avoidance of cycles; a general relationship is not a compulsory path. We do not invent numeric strength where no value is established or turn missing information into false confidence in a recommendation.
A misconception can cross skill boundaries
Relationships need to describe that reach while retaining evidence and review status. Not every hypothesis about an error is an established educational fact. The design distinguishes candidate explanations from supported ones instead of assigning them equal authority.
The same applies to skill packages. Successful parsing and field validation establish technical consistency, not human review. Material does not earn review status by changing a word in a file; the status needs meaning in the approval process.
A coherent package, not scattered edits
Identity, placements and relationships need review together. Editing an isolated row can leave a link pointing to changed meaning or a placement outside its intended edition. Import therefore handles a coherent package validated before writing, with a known version and explicit definition ownership.
Another curriculum mentioning the same skill does not acquire ownership of its definition merely by adding a placement. It can connect that placement to an agreed definition; changing meaning requires an explicit path. This preserves consistency across learning contexts and prevents an ordinary reimport from rewriting a definition used by earlier evidence.
Why this matters to Warda’s direction
This separation supports multiple curricula without claiming they are equivalent, and preserves textbook context without repeatedly redefining the underlying idea. It helps a teacher interpret which capability an attempt concerns, in which context and on what basis.
The account explains identity and relationship design and the limits of inference from evidence. The value is making the object of measurement explicit and reviewable. A catalogue alone does not prove measurement quality or correct inference for every learner.
