Table 2 Pseudocodes for concept map structure evaluation

1

For i = concept map ID 1 to ID n

2

 Proposition = select count (proposition) from proposition table where concept map ID = i

3

 Hierarchy = select max (layer) from concept map table where concept map ID = i

4

 Cross-link = select count (link) from crosslink table where concept map ID = i

5

 Example = select count (example) from example table where concept map ID = i

6

 Score = Proposition+ Hierarchy*5+ Cross-link*2+ Example

7

 Save the score into the concept map table
