The generality of a multilevel factorial model of social competence (SC) for preschool children was tested in a 5‐group, multinational sample (N =1,540) using confirmatory factor analysis. The model fits the observed data well, and tests constraining paths for measured variables to their respective first‐order factors across samples also fit well. Equivalence of measurement models was found at sample and sex within‐sample levels but not for age within sample. In 2 groups, teachers’ ratings were examined as correlates of SC indicators. Composites of SC indicators were significantly associated with both positive and negative child attributes from the teachers’ ratings. The findings contribute to understanding of both methodological and substantive issues concerning SC in young children. 相似文献
The paper discusses the children’s novel Gaffer Samson’s Luck (1984), by Jill Paton Walsh, from three different perspectives; those of a cultural geographer, a literary scholar and an English
teacher. It is part of a larger research project on children’s perception of their place-related identities through reading
and writing. The novel is used as a case study to develop a multidisciplinary approach, drawing upon theories of literature
and reading, and a conceptualisation of space in cultural geography. Employing ideas from different disciplines, the paper
offers an original interpretation of the text as well as innovative analytical tools for future research and for classroom
application. 相似文献
The study compared the agreement, internal consistency, and measurement stability of the GE iDXA, BOD POD, and InBody 720. Body composition of 43 men and 37 women (31.4 ± 10.7 years; 90% Caucasian and 10% other) was assessed in triplicate using each method over two different days. Mean percent body fat (% BF) of the participants was different for all three machines (27.6 ± 10.0% [GE iDXA)] 25.6 ± 10.4% [BOD POD], and 21.3 ± 10.6% [InBody 720]; p < .05). The coefficient of variation for same day repeated measures was 1.06% (GE iDXA), 3.29% (BOD POD), and 2.97% (InBody 720). The coefficient of variation for 2-day repeated measures was 1.81% (GE iDXA), 4.61% (BOD POD), and 4.24% (InBody 720). The difference between the GE iDXA and BOD POD was within acceptable variability, while the InBody 720 significantly underestimated % BF. The internal consistency was highest for the GE iDXA, followed by the InBody 720, and then the BOD POD. 相似文献
Teach For America (TFA), a widespread and well-known route into the teaching profession, frequently partners with university-based education programs to prepare and certify its corps members. However, university-based teacher education programs frequently emphasize very different understandings of socially just education and priorities for training teachers from those of TFA. Accordingly, science teachers trained through TFA-university partnerships encounter conflicting understandings of science education, justice, and urban communities as they are introduced to teaching practice. In this ethnographic case study we explored the experiences and reactions of a cohort of TFA corps members in a science methods course as they engaged with TFA’s perspective focused primarily on enhancing students’ social mobility and the methods course emphasizing democratic equality through scientific engagement. The study considers intersections between TFA’s approach to teacher preparation and sociocultural perspectives on equitable science teaching. The study also lends insight into the contradictions and challenges through which TFA science teachers develop understandings about their role as science teachers, purposes and goals of science education, and identities of the students and communities they serve. 相似文献
Infants as young as 12 months readily modulate their behavior toward novel, ambiguous objects based on emotional responses that others display. Such social-referencing skill offers powerful benefits to infants' knowledge acquisition, but the magnitude of these benefits depends on whether they appreciate the referential quality of others' emotional messages, and are skilled at using cues to reference (e.g., gaze direction, body posture) to guide their interpretation of such messages. Two studies demonstrated referential understanding in 12- and 18-month-olds' responses to another's emotional outburst. Infants relied on the presence versus absence of referential cues to determine whether an emotional message should be linked with a salient, novel object in the first study (N = 48), and they actively consulted referential cues to disambiguate the intended target of an affective display in the second study (N = 32). These findings provide the first experimental evidence of such sophisticated referential abilities in 12-month-olds, as well as the first evidence that infant social referencing at any age actually trades on referential understanding. 相似文献
This study examined the role of reading motivation in reading comprehension achievement of 1070 Chilean third, fourth, and fifth-grade students enrolled in public and private schools. Students were assessed in Spanish reading comprehension and were administered the Motivation to Read Profile from Gambrell, Palmer, Codling and Mazzoni (1996), at the beginning and end of the school year. Results showed that motivation to read at the beginning of the school year was significantly associated with gains in reading comprehension skills. When disaggregating motivation into self-concept and value of reading, only self-concept of reading significantly predicted gains in reading comprehension. Moderation analyses showed that students that started the year with lower reading comprehension and higher motivation to read, had significantly better reading comprehension at the end of the school year, than their peers who started with lower reading motivation. The pedagogical implications are discussed.
As observers of human behavior, infants are faced with a complex flow of motion in which pauses are rare and only occasionally coincide with boundaries between intentional actions. Two studies investigated whether, despite such complexity, 10- to 11-month-old infants (N = 16 for each study) possess skills for parsing ongoing behavior along boundaries correlated with the initiation and completion of intentions. After being familiarized with digitized sequences of continuous everyday action, infants showed renewed interest in test versions in which motion paused in the midst of an actor's pursuit of intentions (interrupting test videos). In contrast, pauses that suspended motion at intention boundary points (completing test videos) sparked no such renewed interest on infants' part. Moreover, basic salience differences between the two types of test videos were not the source of infants' increased interest when intentions were interrupted (Study 2). These findings demonstrate that infants readily detect disruptions of the structure inherent in intentional action, and hence parse ongoing behavior with respect to such structure. Such parsing skill is likely a prerequisite to the development of genuine intentional understanding. 相似文献
Normal toddlers infer the referent of a novel word by consulting the Speaker's direction of Gaze. That is, they use the Speaker's Direction of Gaze (SDG) strategy. This is a far more powerful strategy than the alternative, the Listener's Direction of Gaze (LDG) strategy. In Study 1 we tested if children with autism, who have well-documented impairments in joint attention, used the SDG or the LDG strategy to learn a novel word for a novel object. Results showed that although 70.6% of children with mental handicap passed the test by making the correct mapping between a novel word and a novel object, via the SDG strategy, only 29.4% of children with autism did so. Instead, their reliance on the LDG strategy led to mapping errors. In Study 2 a group of normal children, whose chronological age (24 months old) was eqated with the verbal mental age of the 2 clinical groups in Study I, was tested using a similar procedure. Results showed that 79% of this normal group passed the test by making the correct mapping between a novel word and a novel object using the SDG strategy. Taken together, the results from both studies suggest that children with autism are relatively insensitive to a speaker's gaze direction as an index of the speaker's intention to refer . This result is consistent with previous findings showing that children with autism are relatively "blind" to the mentalistic significance of the eyes. Discussion centers on how the absence of an SDG strategy might disrupt specific aspects of language development in autism. 相似文献
This study compared the efficacy of two cardiac anatomy teaching modalities, ultrasound imaging and cadaveric prosections, for learning cardiac gross anatomy. One hundred and eight first-year medical students participated. Two weeks prior to the teaching intervention, students completed a pretest to assess their prior knowledge and to ensure that groups were equally randomized. Students, divided into pre-existing teaching groups, were assigned to one of two conditions; "cadaver" or "ultrasound." Those in the cadaver group received teaching on the heart using prosections, whereas the ultrasound group received teaching using live ultrasound images of the heart. Immediately after teaching, students sat a post-test. Both teaching modalities increased students' test scores by similar amounts but no significant difference was found between the two conditions, suggesting that both prosections and ultrasound are equally effective methods for teaching gross anatomy of the heart. Our data support the inclusion of either cadaveric teaching or living anatomy using ultrasound within the undergraduate anatomy curriculum, and further work is needed to compare the additive effect of the two modalities. 相似文献
