ABSTRACTMobile students and absent students are important subsets of at-risk students in schools and districts nationwide. As such, student mobility and school absenteeism are two challenges in K-12 education with significant policy and equity implications. Although both issues are at the nexus of schooling and society and there is an apparent overlap in the attributes of these student subgroups, school absenteeism and student mobility are often discussed in separate conversations. This article connects the two disparate literatures in hopes of forging stronger ties that may benefit policymakers, researchers, educators, and students. The limited empirical evidence is mixed but suggests that school absenteeism and student mobility are correlated and absenteeism plays a small mediating role in the relationship between student mobility and student outcomes. The reasons underlying student mobility and student absenteeism are interrelated but not all reasons are common. The overlapping causes of student mobility and chronic absenteeism indicate that economic and social circumstances are important underlying factors. In particular, poverty is a key shared reason for missing or switching schools. Although both phenomena contribute to disparities in educational opportunities, experiences, and outcomes, this study posits that changing schools and missing school provide instructive examples of how inequality in society may be reproduced in districts and schools. Recommendations to address both phenomena and directions for future research are discussed. 相似文献

A relationship between brain responses at birth and later emerging language and reading skills have been shown, but questions
remain whether changes in brain responses after birth continue to predict the mastery of language-related skills such as reading
development. To determine whether developmental changes in the brain-based perceptual skills are systematically related to
differences in word-level reading proficiency at age 8 years, brain event-related potentials (ERPs) to speech and nonspeech
stimuli were recorded annually at the ages of 1 through 8 years in a sample of 109 typically developing children. Two measures
of word-level reading (one that requires decoding of real words and one of pseudowords) were administered at age 8 years.
Growth curve analysis, using the hierarchical linear models, related reading performance (average versus low) to the longitudinal
maturation in the ERP waveform peak and latencies. Maturational changes (e.g., slope, acceleration, and cubic growth) in N1
amplitude from ages 1 to 4 were related to proficiency in decoding pseudoword stimuli only, with children who were less proficient
in decoding pseudowords evidencing more steeply negative declines in amplitude with age, particularly at the frontal and parietal
recording sites in response to both speech and nonspeech stimuli. In contrast, proficiency in decoding real words was related
to developmental changes in N2 amplitudes from ages 4 to 8 only at the parietal recording site, and only in response to nonspeech
stimuli. The early development of biologically based differences in the perception and processing of auditory information
contributes to later group differences in reading proficiencies at school age. 相似文献

Neuropsychology of Early-treated Phenylketonuria: Specific Executive Function Deficits 总被引:14,自引:0,他引:14

This study explored the hypothesis that children with early-treated phenylketonuria (PKU) are selectively impaired on executive function measures, even when still on diet. The rationale for this hypothesis is that even mild elevations in phenylalanine (Phe) can lead to lower central levels of biogenic amines, including dopamine (DA). We hypothesize that this mild DA depletion causes subtle prefrontal dysfunction, which in turn affects executive functions such as set maintenance, planning, and organized search. 11 preschool early-treated PKU children (M age = 4.64) and a sample of age- and IQ-matched unaffected peers (n = 11) were evaluated on a battery of executive function (EF) measures. In addition, a "non-executive function" task, recognition memory, was administered to all subjects. Group comparisons demonstrated that PKU children were significantly impaired on an executive function composite score; there were no group differences, however, in recognition memory. These results supported the hypothesized specific deficit in executive function. Furthermore, within the PKU group the executive function composite score was significantly negatively correlated with concurrent phenylalanine levels, even after controlling for the correlation between IQ and executive function skills. This second finding provides support for the proposed biochemical mechanism underlying the specific cognitive deficits. 相似文献

Congruence between Mothers' and Fathers' Differential Treatment of Siblings: Links with Family Relations and Children's Well-Being 总被引:2,自引:1,他引:2

We studied patterns of mothers' and fathers' differential treatment of firstborn (average age 10.5 years) and secondborn (average age 8 years) school-age siblings, and we examined the links between parents' differential treatment and children's well-being and dyadic family relationships. Mothers, fathers, and both siblings in 110 families were interviewed in their homes. For each dimension of parental behavior that we assessed (i.e., differential affection and discipline) we created groups of families that reflected mothers' and fathers' levels of differential treatment (e.g., discipline the firstborn more, equal treatment, discipline the secondborn more). Although we detected substantial correspondence between the 2 parents' differential treatment, we found a sizable group of families in which parents' reports were incongruent (i.e., 1 parent reported equal and the other differential treatment). Parental patterns were linked to differences between the siblings' well-being and both sibling and parent-child relationships, with younger siblings exhibiting greater vulnerability to differential treatment. Incongruence in differential warmth was associated with marital distress. 相似文献

Many ideas in the biological sciences seem especially difficult to understand, learn, and teach successfully. Our goal in this feature is to explore how these difficulties may stem not from the complexity or opacity of the concepts themselves, but from the fact that they may clash with informal, intuitive, and deeply held ways of understanding the world that have been studied for decades by psychologists. We give a brief overview of the field of developmental cognitive psychology. Then, in each of the following sections, we present a number of common challenges faced by students in the biological sciences. These may be in the form of misconceptions, biases, or simply concepts that are difficult to learn and teach, and they occur at all levels of biological analysis (molecular, cellular, organismal, population, and ecosystem). We then introduce the notion of a cognitive construal and discuss specific examples of how these cognitive principles may explain what makes some misconceptions so alluring and some biological concepts so challenging for undergraduates. We will argue that seemingly unrelated misconceptions may have common origins in a single underlying cognitive construal. These ideas emerge from our own ongoing cross-disciplinary conversation, and we think that expanding this conversation to include other biological scientists and educators, as well as other cognitive scientists, could have significant utility in improving biology teaching and learning. 相似文献

The study examined the extent to which a highly qualified interpreter remained parallel with or diverged from the original classroom discourse in her interpreting for a 3rd-grade deaf student in science, social studies, and resource room. The interpreter's signed and verbalized expressions were compared to the class participants' expressions for meaning equivalence. Parallel interpreting, occurring 33.2% of the time, closely matched the content of the speaker's message. Divergent interpreting, whereby the interpreter added or dropped elements of meaning, occurred 66.8% of the time. Qualitative analyses of classroom footage as well as interviews with the interpreter and the teachers revealed how, when, and why the interpreter diverged from the message. While the interpreter often made intentional reductions and additions to the discourse to achieve greater student understanding of language and course content, there was little awareness of these changes among individualized educational program team members. 相似文献

The development of response inhibition was investigated using a computerized go/no‐go task, in a lagged sequential design where 376 preschool children were assessed repeatedly between 3.0 and 5.25 years of age. Growth curve modeling was used to examine change in performance and predictors of individual differences. The most pronounced change was observed between 3 and 3.75 years. Better working memory and general cognitive ability were related to more accurate performance at all ages, but relations with speed changed with age, where better cognitive skills were initially related to slower responding, but faster responding at later ages. Boys responded more quickly and were more accurate on go trials, whereas girls were better able to withhold responding on no‐go trials. 相似文献

Few studies have identified individual differences in vocational knowledge or its association with career aspirations or expectations of children. We investigated whether individual differences in grade, gender, academic achievement, and SES predict levels of vocational knowledge, and further examined the relationship between vocational knowledge and career aspirations and expectations. Children in the fourth through seventh grades (N = 132) from two rural school districts were administered measures of vocational knowledge, expectations, and aspirations. The results of this study suggest no differences in vocational knowledge in groups differing in grade, gender, and SES; however, academic achievement was a significant predictor of vocational knowledge. Moreover, results of regression analysis demonstrated that vocational knowledge adds significantly to the prediction of career aspirations and expectations. These results contribute to the emerging literature exploring mechanisms involved in the career development of rural children. 相似文献

Nonstandard grammatical forms are often present in the writing of deaf students that are rarely, if ever, seen in the writing of hearing students. With the implementation of Strategic and Interactive Writing Instruction (SIWI) in previous studies, students have demonstrated significant gains in high-level writing skills (e.g., text structure) but have also made gains with English grammar skills. This 1-year study expands on prior research by longitudinally examining the written language growth (i.e., writing length, sentence complexity, sentence awareness, and function words) of 29 deaf middle-school students. A repeated-measures analysis of variance with a between-subjects variable for literacy achievement level was used to examine gains over time and the intervention's efficacy when used with students of various literacy levels. Students, whether high or low achieving, demonstrated statistically significant gains with writing length, sentence complexity, and sentence awareness. Subordinate clauses were found to be an area of difficulty, and follow up strategies are suggested. An analysis of function word data, specifically prepositions and articles, revealed different patterns of written language growth by language group (e.g., American Sign Language users, oral students, users of English-based sign). 相似文献

Teachers of mathematics orchestrate opportunities for interactions between learners and subject matter. Therefore, mathematics
teachers need rich, multidimensional content knowledge for teaching mathematics, which incorporates knowledge of the subject
matter, students, and teaching. Studying this mathematical knowledge for teaching (MKT) necessitates more than a unidirectional
assessment. In this study, the mathematical knowledge for teaching reasoning and proving of two secondary mathematics teachers
was investigated through classroom observations and clinical assessments. Results indicate that using MKT as a frame for examining
classroom practice, in addition to assessing the MKT a teacher possesses in a clinical setting, provides an in-depth and innovative
method for investigating MKT. The comparison of the two cases also identifies student positioning as a key mediating factor
between MKT and opportunities to learn. Implications for using MKT as a lens for examining practice in teacher education are
discussed. 相似文献
