In this study, we seek to describe how the meaning of a tool was co-constructed by the students and their teacher and how the students used the tool to construct mathematical meaning out of particular tasks. We report the results of a qualitative, classroom-based study that examined (1) the role, knowledge and beliefs of a pre-calculus teacher, (2)how students used graphing calculators in support of their learning of mathematics, (3) the relationship and interactions between the teacher's role, knowledge and beliefs and the students' use of the graphing calculator in learning mathematics, and (4) some constraints of the graphing calculator technology that emerged within the classroom practice. We found five patterns and modes of graphing calculator tool use emerged in this practice: computational tool, transformational tool, data collection and analysis tool, visualizing tool, and checking tool. The results of this study suggest that nature of the mathematical tasks and the role, knowledge and beliefs of the teacher influenced the emergence of such rich usage of the graphing calculator. We also found that the use of the calculator as a personal device can inhibit communication in a small group setting, while its use as a shared device supported mathematical learning in the whole class setting.This revised version was published online in September 2005 with corrections to the Cover Date. 相似文献

This study investigates possible developmental trends in children's invented spelling (or spelling errors) in Chinese elementary schools. The entire study consists of two substudies, Study A and Study B. Study A analyzes over 7000 invented spellings collected from the writing samples of 1200 children. Study B analyzes 3995 invented spellings that were collected from the spelling tests of 300 children. These invented spellings are sorted initially according to emerging patterns according to the way the invented spellings deviate from standard spellings; they are then further subsumed into three general categories according to the linguistic principles of Chinese characters - phonologically based spelling errors, graphemic spelling errors, and semantic spelling errors. Qualitative analysis of the invented spellings of these three categories indicates that children's spelling errors are not random; rather they reflect the development of children's orthographic knowledge. Regression analysis for linear trend shows that a developmental trend in the use of spelling strategies exists: at the lower elementary level, phonological strategies predominate; as grade level advances, the use of graphemic and semantic strategies increases. 相似文献

Factors which have been identified as contributing to student academic success at the degree and program level in tertiary study include mode of study, student age, previous tertiary qualifications and past academic performance. Limited published Australian research is available, however, on student academic success in individual subjects. This study investigated identifiable patterns related to the academic success of three separate cohorts of students in an Early Childhood second-year Language, Literature and Literacy unit (N = 601). The data support previous research findings with regard to the effect of mode of study, previous university qualifications and past academic performance on academic success in this subject. In contrast with most previous studies, this study found a significant relationship between previous study at TAFE (college study at a Technical and Further Education institute) and failure in an academic unit, perhaps due to the timing of this unit in the students' overall program. Further implications for Early Childhood teacher education are discussed. 相似文献

This article examines the contested relation between discourses of ethnic subjectivity and queer critique of homophobia and transphobia in Vancouver, a transpacific city in Canada that is being touted as “the most Asian city outside of Asia.” I analyse the perceived association of Chinese communities with moral conservatism and the concomitant existence of a vibrant queer Asian cultural scene in the city as a discursive clash between two cultural publics. I examine the underlying dynamics of their antagonism as well as their potential for mutual engagement. 相似文献

AbstractThis article focuses on the relationship between zoological collections, urban improvement and civic identity in early nineteenth-century Britain. While national zoological collections like London Zoo have been studied by scholars as important sites for research and education, gardens in the provinces have received less attention. The article examines several of these institutions, outlining the circumstances surrounding their foundation and considering how they integrated themselves into their respective local communities through educational initiatives and carefully planned fund-raising strategies. It argues that zoological gardens served to situate cities within a wider imperial context, highlighting their regional importance and global connections. 相似文献

The aim of this study was to compare maximal accumulated oxygen deficit (hereafter O2 deficit) estimated from the methods of Whipp et al. (1986), Medbo et al. (1988), and Hill et al. (1998) to determine whether they agree sufficiently to be used interchangeably. Nineteen moderately to highly trained endurance runners first performed an incremental test to exhaustion for the determination of maximal oxygen uptake ([Vdot]O(2max)) and peak treadmill speed, followed by six randomly ordered constant-speed tests at 95, 100, 105, 110, 110, and 120% of peak treadmill speed. All tests were separated by at least 72 h and were performed within 4 weeks. The method of Whipp produced an O(2) deficit estimate that was lower than that derived from the method of Hill or Medbo (bias +/- 95% limits of agreement: -29.6 +/- 36.6 and -26.1 +/- 32.8 ml . kg(-1), respectively; P < 0.001). The O2 deficit did not differ between the methods of Hill and Medbo (bias +/- 95% limits of agreement: 3.5 +/- 41.6 ml . kg(-1); n.s.). However, poor correlations (0.21 < r < 0.33; n.s.) together with wide limits of agreement between O2 deficit estimates (70 - 80% of the mean response) clearly question using these methods interchangeably. 相似文献
