Despite evidence that young children are sensitive to differences in angle measure, older students frequently struggle to grasp this important mathematical concept. When making judgments about the size of angles, children often rely on erroneous dimensions such as the length of the angles' sides. The present study tested the possibility that this misconception stems from the whole‐object word‐learning bias by providing a subset of children with a separate label to refer to the whole angle figure. Thirty preschoolers (M = 4.86 years, SD = .53) were tested with a pretest–training–posttest design. At pretest, children showed evidence of the whole‐object misconception. After training, children who were given a novel‐word label for the whole object improved significantly more than those trained on the meaning of “angle” alone. 相似文献

A great deal of literature in recent years has focused on the supervisory relationship, yet very little has been written about the nature or content of supervisory meetings, beyond commenting on the frequency and length of meetings. Through semi-structured interviews, informal discussions with colleagues and students, a critical review of literature and personal reflection, this paper explores the salience of coffee for postgraduate supervision. This paper locates supervisions over coffee in reference to contemporary debates about the supervisory relationship (models, styles, tasks and dimensions). Using the concept of ‘third places’ and Misztal's theorisation of informality, it is argued that supervision over coffee conveys a particular supervisory relationship to postgraduate students: one that is incompatible with expert-disciple models or styles of supervision. Instead, supervision over coffee is on neutral territory and on a more informal footing. Finally the paper concludes with discussion about finding a balance between formality and informality in supervision and the development of personal and institutional trust. 相似文献

A group of 110 LD college students were compared to a random stratified sample (RSS) of 153 peers attending the same moderately
selective college between 1980 and 1988. The LD students received comprehensive, highly coordinated support services for at
least one semester. The groups were matched on gender, college experience, semester, and year of entry to the college. The
LD and RSS groups were compared on high school preparation and performance, ACT and college performance, and graduation and
academic failure rate. Although the LD students’ high school records, ACT scores, and college performance were inferior to
that of the RSS group, they graduated at the same rate and within the same time frame. Neither was there any significant difference
in the academic failure rate. Closer examination of the LD graduates and academic failures’ performance showed that in spite
of the similarities in intellectual abilities, academic achievement, and aptitude-achievement discrepancy, two factors differentiated
between the LD graduates and non-graduates: oral language abilities and motivation and attitude toward the teaching-learning
process. These two factors accounted for 60 percent of the variance in graduation status.

The pathways through which exposure to maternal depressive symptoms in early childhood are linked to academic performance during adolescence are poorly understood. This study tested pathways from maternal depressive symptoms (age 2–5) to adolescent academic performance (age 15) through cumulative parenting risk (age 7) and subsequent child functioning (age 10), using multi-informant data from a prospective longitudinal community study spanning 13 years (N = 389, 47% male, 68% White). Structural equation models testing indirect effects revealed small associations between maternal depressive symptoms and increased cumulative parenting risk and poorer child functioning, and, via these pathways, with poorer academic performance. Thus, childhood exposure to maternal depressive symptoms may be associated with pathways of risk that could limit children's educational opportunities. 相似文献

The purpose of this study was to test methods that strengthen the comparability claims about annual determinations of student proficiency in English language arts, math, and science (Grades 3–12) in the New Hampshire Performance Assessment of Competency Education (NH PACE) pilot project. First, we examined the literature in order to define comparability outside the bounds of strict score interchangeability and explored methods for estimating comparability that support a balanced assessment system for state accountability such as the NH PACE pilot. Second, we applied two strategies—consensus scoring and a rank‐ordering method—to estimate comparability in Year 1 of the NH PACE pilot based upon the expert judgment of 85 teachers using 396 student work samples. We found the methods were effective for providing evidence of comparability and also detecting when threats to comparability were present. The evidence did not indicate meaningful differences in district average scoring and therefore did not support adjustments to district‐level cut scores used to create annual determinations. The article concludes with a discussion of the technical challenges and opportunities associated with innovative, balanced assessment systems in an accountability context. 相似文献

Self-appraisals can combine with aspects of the school environment in predicting adolescent emotions and behaviors. This study examined how academic self-efficacy and social self-efficacy are related to anxiety and aggression, and how these relations are moderated by school stressors, academic achievement, and school belonging. The participants of the study were African American and Latino adolescents with an intellectual disability and/or a physical disability. Self-report surveys were completed by 98 adolescents. Regression analyses revealed that higher levels of both self-efficacies were associated with lower levels of anxiety, but these relations were reduced as school stressors increased. Also, high academic self-efficacy was associated with more aggression when academic achievement was low, and high social self-efficacy was associated with more aggression when school belonging was low. The findings have implications for the development of self-efficacy and for the management of adolescent anxiety and aggression. 相似文献
