Social coping and self-concept among young gifted students in Ireland and the United States: a cross-cultural study

Social coping and self-concept were explored among Irish (n = 115) and American (n = 134) grades 3–8 students. Denying one’s giftedness or the impact it has on peer relationships were associated with poor self-concept in both samples. Among Irish students, denying giftedness was associated with more positive self-concept when paired with a high activity level. Engaging in many activities in the US sample and helping one’s peers in the Irish sample were positive predictors of academic self-concept. Findings suggest young gifted students may benefit from learning more about their exceptional abilities and their impact on peers. They should also be encouraged to engage in extracurricular activities and find ways to use their exceptional abilities to support their peers.     

关于高师数学（本科）专业教育教学改革的思考

高师数学（本科）专业教学改革的最重要的工作是进行教学内容和课程体系的改革，要深入开展教学内容和课程体系的改革，除认清现状和新形势下的新要求外，还要转变观念，处理好教学内容与教学时数的关系及共性与个性的关系，同时也应做到3个兼顾。     

Using informed strategies for learning to enhance the reading and thinking skills of children with learning disabilities

The purpose of this study was to improve the reading performance of children with learning disabilities using a classroom-based metacognitive reading program. The participants were third- and fourth-level 8- and 9-year-olds (13 boys and 5 girls) at a school for children with learning disabilities. A cross-sectional time series design was used. During pre- and posttesting participants were assessed on two measures of strategy awareness and a measure of perceived self-competence. During the instructional phase the metacognitive reading program was introduced. Participants were assessed on measures of reading performance throughout the study. In general, the findings were positive: Students increased in performance and awareness of strategies from pre- to posttesting. In addition, participants were placed in subgroups based on pretesting assessments. The subgroups differed on their improvements over time. This study provides preliminary evidence that a metacognitive reading program can be used with children with learning disabilities to improve their awareness about reading and their comprehension skills.     

Measurements of drag and lift on tennis balls in flight

Measurements are presented of drag and lift on new tennis balls in flight. Two video cameras were used to measure the velocity and height of the balls at two positions separated horizontally by 6.4 m. The balls were fired from a ball launcher at speeds between 15 and 30 m/s and with topspin or backspin at rates up to 2,500 rpm. Significant shot-to-shot variations were found in both the drag and lift coefficients. The average drag coefficient was 0.507 ± 0.024, independent of ball speed or spin, and lower than the value usually observed in wind tunnel experiments. The lift coefficient increased with ball spin, on average, but significant lift was observed even at very low spin. The latter effect can be attributed to a side force arising from asymmetries in the ball surface, analogous to the side force responsible for the erratic path of a knuckleball in baseball.     

Ethnic and Racial Identity During Adolescence and Into Young Adulthood: An Integrated Conceptualization

Although ethnic and racial identity (ERI) are central to the normative development of youth of color, there have been few efforts to bring scholars together to discuss the theoretical complexities of these constructs and provide a synthesis of existing work. The Ethnic and Racial Identity in the 21st Century Study Group was assembled for this purpose. This article provides an overview of the interface of ERI with developmental and contextual issues across development, with an emphasis on adolescence and young adulthood. It proposes a metaconstruct to capture experiences that reflect both individuals’ ethnic background and their racialized experiences in a specific sociohistorical context. Finally, it presents milestones in the development of ERI across developmental periods.     

Organising research on university student plagiarism: a process approach

Abstract

This article examines the management of the seemingly ubiquitous problem of plagiarism by students in higher education. An integrated review of the conceptual and empirical literature to date is undertaken in the pursuit of two objectives. First, to provide structure to the scattered knowledge about the topic, which is achieved by developing a process framework of plagiarism management. Second, to identify, group and locate the determinants of each of the major events of the plagiarism management process: the occurrence of a plagiarism instance, its detection and the subsequent actions undertaken in response. Moreover, the framework incorporates the roles of the different actors involved (students, professors and the university) and the importance of the cultural, legal and technological context in which the instances of plagiarism may take place. This process approach aids in the identification of more integrated avenues for further research.     

Association between schoolwide positive behavioural interventions and supports and academic achievement: a 9-year evaluation

This study evaluated the long-term impact of schoolwide positive behavioural interventions and supports (PBIS) on student academic achievement. In this quasi-experimental study, academic achievement data were collected over 9 years. The 21 elementary, middle, and high schools that achieved moderate to high fidelity to the Save & Civil Schools’ PBIS model were matched with 28 control schools to assess academic gains. There were 5 years of baseline data (no intervention in treatment schools) and 4 years of intervention data, including 1 year of maintenance. Results indicate that implementation of the PBIS programme was significantly associated with increased student academic achievement (p = .001) and that the rate of change for students’ academic achievement in treatment schools was greater than for students in control schools. This study suggests that PBIS programmes, such as Safe & Civil Schools’ Foundations, may complement other efforts to improve academic outcomes.     

Theory of mind and conceptual change

We agree with the commentaries by Scholl and Leslie, and also by Moses, that the meta-analytic findings do not definitively rule out early competence accounts. But they do make extant versions of such accounts increasingly unlikely. In particular, the meta-analytic findings argue against executive function expression accounts, including the Theory-of-Mind Mechanism/Selection Processor account advocated by Scholl and Leslie. Specifically, Scholl and Leslie articulate two explicit predictions of their account: that task manipulations that attenuate inhibitory demands should differentially advantage older children, and that theory-of-mind developments should occur with consistent timetables. Both of these specific predictions are clearly contradicted, not supported, by the meta-analytic findings.
