Effects of classroom organization on letter-word reading in first grade

Teacher organization is a crucial part of classroom functioning; however, its relation to student achievement has not been investigated as extensively as that of instruction. In this study, organization is defined as the amount of time teachers spend explaining the purpose and procedures of learning activities and daily routines. Data from first-grade classrooms (N = 44) observed three times during the school year (fall, winter, and spring) are analyzed, along with students' (N = 108) literacy skills at fall and spring. Hierarchical Linear Modeling reveals that, controlling for students' fall word reading and vocabulary skills, as well as amount of language arts instruction they receive, both amount and change in amount over time in classroom organization significantly predicts spring word reading skills. Specifically, children in classrooms observed in higher amounts of classroom time in organization at the beginning of the school year, followed by sharp decreases over the school year, demonstrated stronger letter and word reading skills by spring, and this was a main effect (p < .05). Practical and research implications are discussed.     

Individual and classroom variables associated with relational aggression in elementary-school aged children: A multilevel analysis

Relational aggression was studied within classroom environments by examining individual and classroom correlates among 2731 children (3rd-5th graders) during two successive measurement years. Multilevel analyses yielded small gender differences for relational aggression, indicating that such aggressive behavior was more associated with girls as compared to boys. Findings further demonstrated that relational aggression was positively associated with perceived popularity and peer rejection. Relational aggression was also found to be highly stable over time. Additionally, higher classroom aggression norms, reflected by the classroom level for relational aggression, were associated with increased relational aggression in children. Although variation in relational aggression was situated both at class- and individual-level, differences between individuals were considerably larger than differences between classes. Limitations and further research suggestions are provided and practical implications are discussed.     

Teachers' views and beliefs about bullying: Influences on classroom management strategies and students' coping with peer victimization

A multilevel design was used to test a model in which teachers' attitudes (beliefs) about bullying (e.g., it is normative; assertive children do not get bullied; children wouldn't be bullied if they avoided mean kids) were hypothesized to influence if and how they intervene in bullying interactions. In turn, it was hypothesized that teachers' strategies would influence how their students cope with victimization and the frequency of victimization reported by their students. Data were gathered on 34 2nd and 4th grade teachers and 363 ethnically-diverse students (188 boys; 175 girls; M age = 9 years 2 months). Results indicated that teachers were not likely to intervene if they viewed bullying as normative behavior, but were more likely to intervene if they held either assertion or avoidant beliefs. Moreover, avoidant beliefs were predictive of separating students which was then associated both directly and indirectly (via reduced revenge seeking) with lower levels of peer victimization. No grade differences emerged for teachers' views or management strategies; however, minor sex differences were detected which will be discussed.     

When two paradigms meet: Does evaluative learning extinguish in differential fear conditioning?

Contemporary theories of Pavlovian conditioning propose a distinction between signal learning (SL), in which a conditioned stimulus (CS) becomes a predictor for a biologically significant unconditioned stimulus (US), and evaluative learning (EL), in which the valence of the US is transferred to the CS. This distinction is based largely on the different susceptibilities of EL and SL to extinction. This study compared the extinction of indices of EL (online valence ratings) and SL (US-expectancy ratings and skin conductance responses, SCRs) in a differential fear conditioning design using complex CSs. Only half of the participants gave online valence ratings, allowing us to confirm that online valence measurement did not influence SCRs. In line with the distinction between EL and SL, SCRs extinguished rapidly while valence ratings showed resistance to extinction. US-expectancy ratings, however, were not distinguishable from valence ratings indicating that verbal indicators of EL and SL share a similar time course.     

Deliberative Pedagogy: Ideas for Analysing the Quality of Deliberation in Conflict Management in Education

Institutions worldwide respond to the need to recognise the value of educating children and young people to handle or solve conflicts in communication. But how do they or we know that an event is correctly interpreted as a conflict? How can people analyse the quality of deliberation when handling or solving conflicts in communication in education? I discuss these questions and argue that the notion of conflict cannot be defined only in terms of incompatibility, clash, opposition and/or disagreement; it also has to encompass negativity in the approach to the other. I also argue that the quality of deliberation can be analysed through a deliberative pedagogical approach, which takes into account structural features of deliberation and required dispositions of the participants, and that our knowledge of conflicts emerges holistically and is interpersonal and objective. I begin by giving an account of some institutional responses to conflicts. Then I discuss the notion of conflict and define it, inter alia, in terms of incompatibility, disagreement and negativity. Finally, I discuss ideas for analysing the quality of deliberation in communication when handling or solving conflicts in education.

时间管理倾向与主观幸福感、工作倦怠的关系研究

以220名处级干部为研究对象,探讨了时间管理倾向与主观幸福感、工作倦怠的关系以及时间效能感在时间监控能力和主观幸福感、工作倦怠之间的中介作用.结果表明,时间管理倾向的时间价值感、时间监控能力和时间效能感三个维度与主观幸福感存在显著的正相关,与工作倦怠存在显著的负相关;主观幸福感与工作倦怠存在显著的负相关;时间效能感对时间监控能力与主观幸福感、工作倦怠之间具有部分中介作用,即时间监控能力既可以通过时间效能感影响主观幸福感和工作倦怠,也可以直接影响主观幸福感和工作倦怠.     

How Risk is Perceived, Constructed and Interpreted by Clients in Clinical Genetics, and the Effects on Decision Making: Systematic Review

As an individual’s understanding of their genetic risk may influence risk management decisions, it is important to understand the ways in which risk is constructed and interpreted. We systematically reviewed the literature, undertaking a narrative synthesis of 59 studies presenting data on the ways in which individuals perceive, construct and interpret their risk, and the subsequent effects. While most studies assessed perceived risk quantitatively, the combined evidence suggests individuals find risk difficult to accurately quantify, with a tendency to overestimate. Rather than being a stand-alone concept, risk is something lived and experienced and the process of constructing risk is complex and influenced by many factors. While evidence of the effects of perceived risk is limited and inconsistent, there is some evidence to suggest high risk estimations may adversely affect health and lead to inappropriate uptake of medical surveillance and preventative measures by some individuals. A more focused approach to research is needed with greater exploration of the ways in which risk is constructed, along with the development of stronger theoretical models, to facilitate effective and patient-centered counseling strategies.
