Ethnic–racial identity (ERI) development and ethnic–racial discrimination are two salient experiences among adolescents in the United States. Despite growing awareness of the costs and benefits of these experiences individually, we know little about how they may influence one another. The current study examined competing hypotheses relating discrimination and components of ERI (i.e., exploration, resolution, affirmation) among a sample of Mexican-origin adolescent mothers (N = 181; Mage at Wave 1 = 16.83, SD = 1.01) across six waves of data. Findings revealed that within-person changes in discrimination predicted subsequent ERI resolution and affirmation; however, ERI did not predict subsequent discrimination. Between-person effects of discrimination on affirmation were significant. Our findings underscore the importance of discrimination experiences in shaping Mexican-origin adolescent mothers’ normative developmental competencies.  相似文献

The present study examined the interplay between self-determined motivation and the use of cognitive strategies in predicting university students’ academic performance while taking into account the effect of prior achievement. A theory based model was tested using structural equation modeling on a sample of 764 Italian university students. Results showed that prior achievement influenced students’ academic performance and their motivation and use of cognitive strategies. Critical thinking was the only cognitive strategy which proved to have a significant impact on students’ academic performance. Autonomous motivation had an indirect positive impact on academic performance through its influence on the critical thinking strategy. Controlled motivation had a direct negative impact on academic performance. On the whole, our findings suggest that autonomously motivated students tend to achieve better academic performance by using critical thinking, while students who are driven by controlled motivation have lower academic performance.  相似文献

This article is based on data generated in an ethnographic study of gender in a Swedish preschool. Drawing on Judith Butler’s understanding of performativity and (un)doing of gender, a new theoretical concept, situated decoding of gender, is further developed by showing how the material and spatial dimension of the educational practice and the teachers’ actions contribute to establishing and maintaining this process in an early childhood educational setting. Instead of normalising the gender binary, a reverse process occurs that turns what is perceived as feminine or masculine into a gender decoded state in which gender is made less relevant, or even irrelevant. It is argued that this continuous reiterative process emerges and is maintained by three main factors: (a) the preschool’s physical environment, (b) the regular and repetitive structure of the educational practice and (c) the consistent actions of the teachers in the everyday practice.  相似文献

Science learning is inextricably tied to two aspects of students’ lives: literacy and culture. While English Learners (ELs) who speak a non-English native language are typically the focus in this line of scholarly inquiry, deaf and hard-of-hearing (DHH) students occupy a distinct space in this conversation. For DHH learners, literacy levels can be hindered by an early dependence on a more survival-based language learning model that postpones basic scientific inquiry. The vocabulary for curiosity is limited, which in turn affects the educational culture. DHH learners have a unique culture that demands an appropriate science curriculum, which thus far has not been explored or attempted for either DHH learners or their educators. Data collected consisted of interviews with teachers of DHH students, as well as observational data collected from a high-minority urban K-8 school for DHH students. The analysis revealed that, first, many of the teachers had limited preparation to teach science content. Second, DHH teachers used inconsistent instructional strategies ranging from drawing pictures to building models. Third, the modifications provided to DHH science learners were mostly limited to visual support and repetition. Implications for teacher education programs include instruction focused on specific supports for DHH students and co-teaching methods, and deeper investigation of inquiry-based science practices. Implications for classroom practices include providing hands-on, inquiry-based instruction, working closely with parents, and developing students’ and teachers’ understanding of scientific inquiry.

Response to intervention (RTI) is advocated in elementary school as a system‐wide, multitiered model of academic and behavioral interventions. Middle schools have begun adopting RTI models based on these existing elementary models. This investigation into current middle school RTI practices describes technical aspects as well as some of cultural and contextual issues surrounding implementation. The study included multiple data collection procedures including surveys, discussion groups, phone interviews, and site visits. Although many schools reported substantial progress with implementation, they recognized rigorous implementation of RTI posed such on‐going challenges as changes in staffing, curricular realignments, very limited selections of screening and progress monitoring tools aligned with their curriculum, and scheduling of secondary and tertiary level interventions.  相似文献

Factors related to grade point average (GPA) are of great importance for students' success. Yet, little is known about the impact of individual differences in emotional reactivity on students' academic performance. We aimed to examine the emotional reactivity–GPA link and to assess whether self‐esteem and psychological distress moderate this relationship. Eighty undergraduate students reported on their GPA, self‐esteem, and psychological distress. Students' pupil radius was monitored during affective picture viewing to assess sympathetic activation in response to emotional stimuli. Cluster analysis on pupil reactivity to pictures identified low, average, and high emotionally reactive students. Regression analyses indicated that profiles of emotional reactivity were associated with GPA. This relationship was moderated by self‐esteem, but not psychological distress. Among students with higher emotional reactivity, those with lower self‐esteem reported poorer GPA. Findings document the importance of differences in students' emotional reactivity and self‐esteem in relation to academic success.  相似文献

This article describes how the National Science Foundation's support of information research has evolved from NSF's original mission of improving the dissemination of scientific and technical information to its present interest in information robotics and intelligent systems. The pattern of grant support, since a major reorganization of the information science division in 1978, is analyzed in terms of the institutions, the investigators, and the disciplines that have been major grant recipients.  相似文献
