Why the relationship label is the teaching part
Ms Patel puts six water-cycle concepts on the board. Her class can draw seven lines between them in under two minutes. That proves the words feel related, but it does not show what anyone understands. One student may connect evaporation and heat because heat causes evaporation. Another may think evaporation produces heat. The line looks identical. The label exposes the difference.
A useful concept map is read as a set of short propositions: concept, relationship phrase, concept. “Heat causes evaporation” makes a claim that can be checked. “Evaporation changes liquid water into water vapour” makes a second claim. If the sentence is vague or false, the map has found the exact point that needs teaching.
- Cause and effect: causes, increases, reduces, leads to, prevents.
- Structure: contains, is part of, is made from, has the feature.
- Classification: is a type of, is an example of, differs from.
- Process and sequence: becomes, happens before, produces, requires.
- Evidence and measurement: is shown by, is measured with, supports the claim.
Ask students to read every arrow aloud after building the map. If all three parts form a precise sentence, the connection is doing real explanatory work. If the best label is only “is related to,” ask what the relationship actually is.
