Concept — a blackboard is a shared, erasable surface for developing and displaying ideas during a lesson.

Activities whose classroom purpose is the visible process of editing, drawing or mapping can be completed on that surface. Producing a formal document is different because the structured artifact itself must exist independently of the temporary display.

Applying the process-versus-document distinction:

• Improving a paragraph can be carried out through successive visible edits to a draft.

• Showing schematic diagrams can be carried out by adding labelled parts and connections while explaining them.

• Summarising relationships between facts can be carried out by arranging headings, arrows or a grid during discussion.

• Preparing a report from information produces a structured document with sections, figures and a conclusion; the report itself must be created on a durable medium rather than exist only on an erasable board.

Cross-check by the required product: paragraph revision, schematic display and relationship mapping are classroom processes that achieve their immediate purpose on the board, whereas report preparation is defined by the completed document it produces.

Therefore, preparing a report from information is the activity that generally requires a separate permanent document.
