Bullying and harassment by school peers has received increasing attention as their relation to personal problems and more extreme forms of violence has become better recognized. Emphases of empirical studies have focused on characteristics and behaviours of both school bullies and their victims. There is a need to place these traits and actions into the context of the situation in which they occur, in order to expand the research and allow for the development of more sophisticated and comprehensive educational, prevention and intervention programmes. A total 251 professionals (teachers and counsellors) participated in this empirical study on the ability of professionals to differentiate between bullying and other forms of conflict. Participants were asked to judge the severity of 21 scenarios depicting different combinations of situational characteristics and also whether they constituted bullying situations or not. Results indicated that physical threat or abuse was seen as more severe than verbal or social/emotional abuse, and professionals more often rated physical conflicts as bullying even when they did not fit the definition. The repeated nature of an abusive relationship and an unfair match between participants were bullying situation characteristics found to be related to the responses of more and less effective situation evaluators. Implications for pre- and in-service training of educators were considered based on study results and previous research.  相似文献   

Exploring young children’s self-efficacy beliefs related to mathematical and nonmathematical tasks performed in kindergarten: abused and neglected children and their peers

This article reports on young children’s self-efficacy beliefs and their corresponding performance of mathematical and nonmathematical tasks typically encountered in kindergarten. Participants included 132 kindergarten children aged 5–6 years old. Among the participants, 69 children were identified by the social welfare department as being abused and/or neglected. Individual interviews were conducted where children were asked to assess their self-efficacy regarding sorting tasks, mathematics tasks, and reciting the alphabet. Children were then requested to perform each of the tasks. Results revealed that no significant differences were found between the abused and neglected children and their peers regarding their self-efficacy beliefs and performances for any of the tasks. For some of the tasks, children were able to correctly assess their performance, while for other tasks, children overestimated their performance. Possible reasons for these outcomes are discussed.  相似文献   

Advice from Rural Elders: What it Takes to Age in Place     

Cheryl J. Dye  Deborah F. Willoughby  Dina G. Battisto 《Educational gerontology》2013,39(1):74-93

Older adults prefer to age in place (AIP), and there are psychological, physiological, and economic benefits in doing so. However, it is especially challenging to AIP in rural communities. AIP models have been tested in urban settings and age-segregated communities, but they are not appropriate for rural communities. This paper presents rural AIP variables identified in the literature as well as those described by 39 older adults in five focus groups.  相似文献   

Simplifying Algebraic Expressions: Teacher Awareness and Teaching Approaches     

Dina Tirosh  Ruhama Even  Naomi Robinson 《Educational Studies in Mathematics》1998,35(1):51-64

This study investigates four seventh-grade teachers' awareness of students' tendency to conjoin or 'finish' open expressions. It also investigates teachers' ways of coping with this tendency. Three types of data were collected: 1) lesson plans, 2) lesson observations, and 3) post-lesson interviews. The analysis showed that the two experienced teachers were aware of this tendency and some of its possible sources, while the novices were unaware of either. Teaching approaches related to this tendency also differed considerably. In conclusion we analyze these teaching methods in light of the existing literature and discuss possible short- and long-term implications of the use of each approach.  相似文献

State-of-the-art in biomedical literature retrieval for clinical cases: a survey of the TREC 2014 CDS track     

Kirk Roberts  Matthew Simpson  Dina Demner-Fushman  Ellen Voorhees  William Hersh 《Information Retrieval》2016,19(1-2):113-148

Providing access to relevant biomedical literature in a clinical setting has the potential to bridge a critical gap in evidence-based medicine. Here, our goal is specifically to provide relevant articles to clinicians to improve their decision-making in diagnosing, treating, and testing patients. To this end, the TREC 2014 Clinical Decision Support Track evaluated a system’s ability to retrieve relevant articles in one of three categories (Diagnosis, Treatment, Test) using an idealized form of a patient medical record. Over 100 submissions from over 25 participants were evaluated on 30 topics, resulting in over 37k relevance judgments. In this article, we provide an overview of the task, a survey of the information retrieval methods employed by the participants, an analysis of the results, and a discussion on the future directions for this challenging yet important task.  相似文献   

Cross-and same-race friendships of Vietnamese immigrant adolescents: A focus on acculturation and school diversity     

Wing Yi Chan  Dina Birman 《Int J Intercult Relat》2009,33(4):313-324

The purpose of this study was to examine friendship developments of 153 Vietnamese immigrant adolescents who resided in an East Coast metropolitan area of the United States. We examined the influences of school diversity and acculturation on the quantity and quality of cross-and same-race friendships. Surprisingly, students who came from schools that are more diverse reported fewer cross-race friendships and lower levels of social support from their cross-race friends. American acculturation predicted greater levels of social support from cross-race friends. For same-race friendships, students who went to schools with higher percentage of Asian students reported more same-race friendships; however, percentage of Asian students was not a significant predictor of social support from same-race friends. Students who reported greater levels of Vietnamese acculturation reported greater levels of social support from their same-race friends. This study has implications for understanding the impact of school diversity and acculturation on friendship development of Vietnamese immigrants. Also, suggestions on how to better conceptualize and measure diversity are discussed.  相似文献   

Intuitive rules in science and mathematics: the case of ‘more of A ‐‐ more of B’     

Ruth Stavy  Dina Tirosh 《International Journal of Science Education》2013,35(6):653-667

In the last twenty years researchers have studied students’ mathematical and scientific conceptions and reasoning. Most of this research is content‐specific. It has been found that students often hold ideas that are not in line with accepted scientific notions. In our joint work in mathematics and science education it became apparent that many of these alternative conceptions hail from the same intuitive rules. We have so far identified two such rules: ‘The more of A, the more of B’ and, ‘Everything can be divided by two’. The first rule is reflected in students’ responses to many tasks, including all classical Piagetian conservation tasks (conservation of number, area, weight, volume, matter, etc.), in all tasks related to intensive quantities (density, temperature, concentration, etc.), and in tasks related to infinite quantities. The second rule is observed in responses related to successive division of material and geometrical objects, and in successive dilution tasks. In this paper we describe and discuss the first rule and its relevance to science and mathematics education. In a second paper (Tirosh and Stavy, in press) we shall describe and discuss the second rule.  相似文献   

Mathematically based and practically based explanations in the elementary school: teachers’ preferences     

Esther Levenson  Pessia Tsamir  Dina Tirosh 《Journal of Mathematics Teacher Education》2010,13(4):345-369

This article focuses on elementary school teachers’ preferences for mathematically based (MB) and practically based (PB) explanations. Using the context of even and odd numbers, it explores the types of explanations teachers generate on their own as well as the types of explanations they prefer after reviewing various explanations. It also investigates the basis for these preferences. Results show that teacher-generated explanations include more MB explanations than PB explanations. However, many still choose to use mostly PB explanations in their classrooms, believing that these explanations will be most convincing to their students. The implications for teacher education are discussed.  相似文献   

THE EFFECT OF INTERVENTION ON ACCURACY OF STUDENTS’ RESPONSES AND REACTION TIMES TO GEOMETRY PROBLEMS     

Reuven Babai  Hanna Zilber  Ruth Stavy  Dina Tirosh 《International Journal of Science and Mathematics Education》2010,8(1):185-201

This study investigates the effect on student performance in drawing their attention to relevant task variables, focusing on accuracy of responses and reaction times. We chose this methodology in order to better understand how such interventions affect the reasoning process. The study employs a geometry task in which the irrelevant salient variable (area) interferes with the reasoning process related to perimeter comparison. We compared eighth graders’ performances in a pretest and a posttest, with or without intervention. The posttest results showed that raising students’ awareness of the relevant task variable activates effortful and time-consuming control mechanisms which help them overcome the interference of the irrelevant variable. The paper discusses the educational importance of helping students to attend selectively to relevant information in order to overcome interference, thus promoting logical reasoning.  相似文献
