This paper considers the development of school students’ ability to define three terms that are fundamental to statistical
literacy: sample, random, and variation. A total of 738 students in grades 3, 5, 7, and 9 were asked in a survey to define
and give an example for the word “sample.” Of these, 379 students in grades 7 and 9 were also asked about the words “random”
and “variation.” Responses were used to describe developmental levels overall and to document differences across grades on
the understanding of these terms. Changes in performance were also monitored after lessons on chance and data, emphasizing
variation for 335 students. After 2 years, 132 of these students and a further 209 students who were surveyed originally but
did not take part in specialized lessons, were surveyed again. The difference after 2 years between the performance of students
who experienced the specialized lessons and those who did not was considered, revealing no differences in performance longitudinally.
For students in grades 7 and 9, the association of performance on the three terms was explored. Implications for mathematics
and literacy educators are discussed. 相似文献

Several tasks used in research studies are presented with assessment rubrics and examples of the development of student understanding. The tasks focus on students’ appreciation of variation in several contexts and illustrate the need to discuss variation in the classroom and to ask students specifically about it during assessment. 相似文献

This study compared private speech of children with ADHD and normal controls during problem solving and inhibition tasks. Thirty-two children (16 children with ADHD and 16 matched controls) aged 6–11 years participated. Consistent with previous studies, children with ADHD produced more task-irrelevant and task-relevant external private speech than control children during problem-solving tasks, but did not differ in their use of task-relevant internal private speech. During the inhibition/attention task (Continuous Performance Test-II), children with ADHD produced more task-relevant external and more task-relevant internal private speech, suggesting that they may have employed a less mature strategy to aid in self-regulation. The educational implications of the current study are that there should be an increased awareness of the developmental nature and functional significance of private speech and how private speech usage may differ in children with ADHD. 相似文献

Adult benefits for participants in Project CARE were compared with those of the Abecedarian Project, a closely related randomized study of early childhood educational intervention for children from low-income families who were at risk of developmental delays and school failure. CARE replicated Abecedarian's young adult treatment-related educational and vocational attainment gains. CARE data also supported the Abecedarian reduction in marijuana use. Treated individuals in both studies reported adopting a more active life style. The average age at birth of a first child, the number of children, and the proportion of teen parents were positively affected in the Abecedarian sample but not in CARE. Finding significant educational and vocational gains lasting into young adulthood in the CARE study reinforces Abecedarian young adult findings and strengthens the case for early childhood intervention for children from low-income families. 相似文献

Considerable discussion has occurred about the most appropriate methods for diagnosing learning disabilities (LD) in postsecondary students. Two of the many areas of controversy that have emerged include the appropriate diagnostic criteria to use and the appropriate referent group. A review of previous court cases demonstrates that the issue of whether to compare an individual to the general population or to a smaller referent population has not been adequately clarified. Furthermore, few empirical studies have examined the impact of choosing different referent groups on the likelihood that one will be diagnosed with LD. Therefore, this correlational study described the levels of agreement between three diagnostic models of LD, using both age- and grade-based norms to represent two referent groups for each of the three models. The sample included 155 postsecondary students referred for testing due to academic difficulties. The findings indicated that in two of the three models tested, comparing individuals to their grade-matched peers (i.e., using grade-based norms) resulted in more LD diagnoses than comparing individuals to their age-matched peers (i.e., age-based norms). 相似文献
