Mental toughness can be conceptualised as a set of attributes that allow people to deal effectively with challenges, stressors and pressure. Recent work has suggested that it may be a valuable construct to consider within educational settings. The current studies explored the associations between mental toughness and educational transitions. Study 1 examined the relationships between mental toughness and concerns about moving to a new school in 105 children aged 12–13 years of age. The results revealed significant relationships between several aspects of mental toughness, but particularly confidence in abilities, and children’s concerns. Study 2 examined the relationships between mental toughness and adjustment to university in 200 undergraduate students at various stages of their course. The results revealed a role for several aspects of mental toughness; commitment, control of life, control of emotion, confidence in abilities and interpersonal confidence. The results are discussed in terms of implications for educational practice. It is suggested that measures of mental toughness could be used to identify individuals who may benefit from additional support during transition to a new school or to university, and that future research should explore the potential benefits of mental toughness training.  相似文献

Previous research has found that researchers rank journal reputation and impact factor (IF) amongst the key selection criteria when choosing where to submit. We explored the actual effect upon submission numbers of several possible factors. We retrieved 10 years of submission data from over a thousand journals, as well as data on IF, retractions, and other factors. We performed statistical analysis and identified correlations. We also undertook case study research on the 55 most significant submission decreases. We found a statistically significant correlation between changes in IF, ISI percentage ranking, and changes in submissions numbers in subsequent years. We also found a statistically significant effect on submission numbers in the year following the publication of a retraction. Our case studies identified other factors, including negative feedback on the peer review process. Our findings regarding IF confirm previous indications about the significance of IF on submissions. We explain the correlation with retractions through the concept of ‘peer review reputation’. These results indicate that editors and publishers need to focus on a journal's peer review practices, as well as a journal's IF, if they are to maintain and grow submissions.  相似文献

Intelligent use of the many diverse forms of data available on the Internet requires new tools for managing and manipulating heterogeneous forms of information. This paper uses WHIRL, an extension of relational databases that can manipulate textual data using statistical similarity measures developed by the information retrieval community. We show that although WHIRL is designed for more general similarity-based reasoning tasks, it is competitive with mature systems designed explicitly for inductive classification. In particular, WHIRL is well suited for combining different sources of knowledge in the classification process. We show on a diverse set of tasks that the use of appropriate sets of unlabeled background knowledge often decreases error rates, particularly if the number of examples or the size of the strings in the training set is small. This is especially useful when labeling text is a labor-intensive job and when there is a large amount of information available about a particular problem on the World Wide Web.

OBJECTIVE: To describe the development of the Cochrane Behavioral Medicine Field database of interventions and its contribution to the knowledge base of this field. METHODS: A list of behavioural medicine interventions was solicited from content experts. The resulting list of index terms was used to generate a comprehensive search strategy to retrieve relevant records, and a thesaurus of terms with which to index them. The records are included in a register. A subset of records have been coded for study design, health condition, intervention, study participants, setting and provider and made available in a public online database. RESULTS: The Cochrane Behavioral Medicine Field database consists of over 3500 records of systematic reviews, meta-analyses and randomized controlled trials for public educational use. CONCLUSIONS: The register provides a comprehensive listing of studies relating to behavioural medicine interventions. The public online database enables easy access to the evidence base and provides enhanced details of the studies included on it. These databases are a valuable resource for the behavioural medicine community. Other fields are encouraged to duplicate these methods in the design of content-specific databases.  相似文献

The perceived spatiotemporal continuity of objects depends on the way they appear and disappear as they move in the spatial layout. This study investigated whether infants' predictive tracking of a briefly occluded object is sensitive to the manner by which the object disappears and reappears. Five-, 7-, and 9-month-old infants were shown a ball rolling across a visual scene and briefly disappearing via kinetic occlusion, instantaneous disappearance, implosion, or virtual occlusion. Three different measures converged to show that predictive tracking increased with age and that infants were most likely to anticipate the reappearance of the ball following kinetic occlusion. These results suggest that infants' knowledge of the permanence and nonpermanence of objects is embodied in their predictive tracking.  相似文献

Becoming a student teacher: core features of the experience   总被引:2,自引:2,他引:0  
This paper reports early findings of a longitudinal research project on the experiences of beginning teachers in England. In the first phase of the study (2003–2004), data were generated via: (1) in‐depth, face to face interviews with 85 student teachers throughout England; and (2) self‐completion questionnaires, returned by 4,790 student teachers across a range of initial teacher preparation (ITP) routes. Through these methods the study set out to explore student teachers' accounts of their motivations for entering ITP, their preconceptions and expectations of teaching and ITP, and their early experiences as student teachers. A number of general themes were found to cut across all of these areas, and are presented here as core features of the experience of becoming a student teacher. These relate to the concept of teacher identity, the role of relationships, the notion of relevance, and the central presence of emotion.

Cette étude décrit les conclusions préliminaires d'une recherche continue sur les expériences de ceux qui sont en train de devenir professeurs d'école en Angleterre. En première phase de l'étude (2003–2004), les données ont été recueillies par: 1) des entretiens approfondis en tête‐à‐tête avec 85 professeurs stagiaires dans toute l'Angleterre; et 2) des questionnaires, remplis eux‐mêmes par 4,790 professeurs stagiaires sur un échantillon de préparations initiales de professeur (PIP). Avec ces méthodes l'étude avait pour but d'explorer les explications des professeurs stagiaires concernant leur motivation pour entrer dans la PIP, leurs idées reçues et leurs attentes de l'enseignement et de la PIP, ainsi que leurs expériences initiales de professeur stagiaire. On a trouvé un nombre de thèmes généraux à travers tous ces domaines, et ceux‐ci sont présentés ici comme caractéristiques fondamentales de l'expérience vécue de professeur stagiaire débutant. Ils sont relatifs aux concepts suivants : l'identité du professeur, le rôle des relations, la notion de pertinence et la présence capitale de l'émotion.

Este documento es un informe sobre los primeros resultados de un proyecto de investigación longitudinal sobre las experiencias de profesores principiantes en la Inglaterra. En la primera fase del estudio (2003–2004), los datos fueron obtenidos a partir de dos fuentes: minuciosas entrevistas cara a cara con 85 profesores en prácticas por toda Inglaterra y cuestionarios personales que fueron devueltos por 4,790 profesores en prácticas procedentes de distintas ramas de la ITP (preparación para profesores principiantes). A través de estos métodos, el estudio fue lanzado con el propósito de sondear las razones que motivaron a los profesores en prácticas a entrar en la ITP, sus preconcepciones y expectativas en cuanto a la ITP y a dar clase y sus primeras experiencias como profesores en prácticas. Estas áreas presentaron una serie de temas generales comunes que son presentados aquí como características centrales de la experiencia de convertirse en profesor en prácticas. Estas están relacionadas con el concepto de identidad del profesor, la importancia de las relaciones, la noción de relevancia, y el papel central de las emociones.

Dieses Referat berichtet über die ersten Ergebnisse eines langfristigen Forschungsprojektes, basierend auf Erfahrungen von Lehrern in England, die in den Beruf einsteigen. In der ersten Phase der Studie (2003–2004) wurden Daten gesammelt mittels: 1) ausführlicher, persönlicher Gespräche mit 85 auszubildenden Lehrern aus ganz England; und 2) selbstauszufüllender Fragebögen, die von 4,790 auszubildenden Lehrern aus verschiedenen Ausbildungsrichtungen zurückgesendet wurden. Die Studie hatte das Ziel, die Berichte der auszubildenden Lehrer zu untersuchen hinsichtlich ihrer Motivation, eine Ausbildung anzufangen, ihrer Erwartungen vom Unterrichten und von der Ausbildung, sowie ihrer ersten Erfahrungen als auszubildende Lehrer. Eine Anzahl von allgemeinen Themen wurden in allen diesen Bereichen festgestellt und sind hier als Kernmerkmale des Ausbildungsverfahrens dargestellt. Diese beziehen sich auf das Konzept der Lehreridentität, auf die Rolle von Beziehungen, auf die Idee der Relevanz, sowie auf die zentrale Präsenz von Emotionen.  相似文献

Impact of a statewide home visiting program to prevent child abuse   总被引:1,自引:0,他引:1  
OBJECTIVES: To assess the impact of a voluntary, paraprofessional home visiting program in preventing child maltreatment and reducing the multiple, malleable psychosocial risks for maltreatment for which families had been targeted. METHODS: This collaborative, experimental study focused on 6 Healthy Families Alaska (HFAK) programs; 325 families were enrolled in 2000-2001, randomized to intervention and control groups, and interviewed to measure baseline attributes. Follow-up data were collected when children were 2 years old (85% follow-up rate). Outcomes included maltreatment reports, measures of potential maltreatment and parental risks, for example, poor mental health, substance use, and partner violence. HFAK records were reviewed to measure home visiting services. Home visitors were surveyed to measure perceived effectiveness and training adequacy. RESULTS: Parental risks were common at baseline, and one-sixth of families had a substantiated child protective services report in the child's first 2 years of life. There was no overall program effect on maltreatment reports, and most measures of potential maltreatment. Home visited mothers reported using mild forms of physical discipline less often than control mothers. The groups were similar in their use of more severe forms of physical discipline. There was no program impact on parental risks. There was no impact on outcomes for families with a 'high dose' of home visiting. Home visitors often failed to address parental risks and seldom linked families with community resources. Contradictions in the model compromised effectiveness. CONCLUSIONS: The program did not prevent child maltreatment, nor reduce the parental risks that had made families eligible for service. Research is needed to develop and test strategies to improve the effectiveness of home visiting.  相似文献

Engaging students in a challenging (cognitively demanding) task and launching a mathematics lesson with a task before instruction are two characteristics of a reform-oriented approach to mathematics instruction often considered together. The authors systematically contrasted teaching with challenging tasks using a task-first lesson structure with that of a discussion-first lesson structure to three composite classes of first- and second-grade students (n = 73). Subsequent assessments of mathematical performance revealed that the discussion-first lesson structure was somewhat more efficacious in improving fluency performance but both structures similarly improved problem-solving performance. The findings suggest there is more than one way of incorporating challenging tasks into mathematics lessons to produce sizeable learning gains.  相似文献

This mixed-methods study examines engaging teaching at one racially and ethnically diverse public school using the self-system process model of student engagement. As theorized, multilevel analyses of student survey data (N?=?580) reveal that student perceptions of structure, autonomy support, and involvement differentiate highly, moderately, and weakly engaging teachers. Classroom observations (N?=?12) and student interviews (N?=?17) suggest that the behavior of autonomy supportive and involved teachers is friendly, helpful, and emphasizes student agency. Although few racial or ethnic differences are observed, autonomy supportive and involved teacher behavior appears particularly critical to the behavioral engagement of Black and Latinx students. Helpfulness may also moderate stereotype threat. Implications for researchers, practitioners, and policy-makers are discussed.
