Development of a Three-Tier Number Sense Test for Fifth-Grade Students
Yang, Der-Ching
Educational Studies in Mathematics, v101 n3 p405-424 Jul 2019
To assess the strength of conceptual understanding of number sense, a three-tier number sense test (TTNST) for fifth-grade students was developed and validated in this study. The three-tier test includes a content tier that assesses content knowledge of number sense, a reason tier that assesses a reason given for selecting a first-tier response, and a confidence tier that assesses how confident fifth-grade students are in their responses in the first two tiers. A total of 819 fifth-grade students from elementary schools in Taiwan participated in this study. Collected data showed that the test had good reliability and validity. The results revealed that many of the sample students performed poorly on number sense but maintained extremely high confidence; this indicated that many of the students held severe misconceptions and some were lacking in number sense. In addition, this study confirmed that the inclusion of a third tier (with confidence ratings) in the number sense test can mitigate the weaknesses of a previously used two-tier test. The educational implications of the findings are discussed in this paper.
