ab: Summary: To investigate the structure of number sense and then to assess
its uses in fifth-grade children’s number sense development, a
computerized number sense scale was developed and evaluated. The
findings of the study indicate that the newly developed scale, with
four dominant factors identified and reconfirmed, is internally
consistent and substantially valid. It can be reliably used as a
screening measure for a quick check of students’ number sense
development via online self-assessment. Compared with our previous
study, both qualitative and quantitative changes were detected in
students’ number sense development at different grades. The
qualitative change in number sense development is manifested in
different numbers of factor components produced at different grades.
The quantitative change is manifested in different amounts of factor
variance explained at different grades. Furthermore, among the four
aspects of number sense, Taiwanese students perform best on recognizing
the relative number size yet relatively worse on judging the
reasonableness of computational results. (Contains 4 tables.) (ERIC)
