The purpose of the study was to obtain performance data on the number sense ability of Taiwanese students at grades six and eight and to identify thinking strategies as individual students solved items which were intended to reveal their number sense.

520 $a The purpose of the study was to obtain performance data on the number sense ability of Taiwanese students at grades six and eight and to identify thinking strategies as individual students solved items which were intended to reveal their number sense.
520 $a A total of 115 sixth-grade and 119 eighth-grade Taiwanese students completed a number sense test, mental computation test, and written computation test. The sixth-grade means were 35.6, 18.0, and 13.4, and the eighth-grade means were 45.5, 22.2, and 14.6 for the NST (80 points maximum), MCT (25 points maximum for sixth grade and 30 points maximum for eighth grade), and WCT (20 points maximum), respectively.
520 $a A stratified, random sample of 17 students was drawn from the high (N = 9) and middle (N = 8) groups. The high group students were those who scored in the top 10% and the middle group students were those who scored between 45% to 55%, respectively, on the three tests: NST, MCT, and WCT. These students were interviewed with number sense related items.
520 $a Analysis of results indicated that number sense performance level for the sixth and eighth graders was lower than their MCT and WCT performance. Significant differences between WCT and parallel NST items suggested that students who could correctly carry out the exact computation by paper-and-pencil were not necessarily successful in applying these skills in non-computational situations. Results indicated that significant differences in performance between grade levels on the number sense test existed. However, there was no significant gender difference on the number sense test for sixth and eighth graders in Taiwan.
520 $a The results showed that sixth and eighth grade Taiwanese students' previous year mathematics achievement score was the best predictor among the other factors for student number sense performance.
520 $a Individual interviews with students showed that middle ability students tended to use the paper-and-pencil computation algorithms more often than high ability students when answering number sense interview items. The interviews document that high ability students reflected a wider range of characteristics of number sense than middle ability students.
