To achieve goal, three on-line achievement tests were administrated to a sample of 286 elementary students in Taipei. The collected data were analysis by the PDAKS and Tester 2.0 computer software.
The main findings were as follows:
- The knowledge structure maps among students of different scholastic-ability were different.
