The present experiment investigated the effects of kinship and familiarity upon food sharing in pairs of albino rat pups. Five pairs of rats from each of the following groups were tested: (1) familiar siblings, (2) nonfamiliar siblings, (3) familiar nonsiblings, and (4) nonfamiliar non-siblings. A small food portion was used, necessitating not only close physical contact, but also cooperation in the sense that both pups were required to remain relatively immobile in order for both to feed simultaneously. Results indicated more frequent sharing among unfamiliar pups, whether related or not. Results also indicated that food sharing increased in frequency among all four groups over the 5-day testing period, suggesting that cooperation in the form of food sharing can develop, or increase in frequency, over time in albino rat pups. 相似文献

In this study, the relationship between student affective performance and classroom physical environment, social climate, and management style were investigated in a sample of classes in Hong Kong primary schools. The results of Pearson and canonical correlation analyses indicated that among the measures of classroom environment, perceived quality of physical environment and class master's expert power, personal power, and coercive power were the strongest predictors of affective performance. This finding supports the importance of class master's management style in the classroom environment. Students' attitudes toward school and teachers appeared to be most sensitive to variation in the classroom environment, and self-concept was the least sensitive among the seven student affective measures. Students' self-efficacy of learning and intention to drop out were moderately sensitive to classroom environment. Profiles of effective and ineffective classroom environments were also mapped. In effective classrooms, class masters care for students, pay attention to teaching, do not use force or punishment but do create a good classroom climate with their professional knowledge, personal morality, and personality. Physical environment and psychological environment are both important; a good classroom environment is highly correlated with student affective performance. 相似文献

Foetal alcohol spectrum disorder (FASD) is the most common non‐genetic cause of learning disability, affecting around 1% of live births in Europe, and costing an estimated $2.9 million per individual across their lifespan. In adulthood, non‐reversible brain damage is often compounded by secondary disabilities in adulthood, such as mental health problems and drug addiction. The challenge for today's educators is: ‘How do we teach children with FASD?’ Their unusual style of learning and their extreme challenging behaviour is out of the experience of many teachers. This article, written by Professor Barry Carpenter, OBE, National Director of the Specialist Schools & Academies Trust Complex Learning Difficulties and Disabilities Research Project, considers the status of FASD in the UK, and provides an overview of the author's recent research into effective educational strategies within the framework of Every Child Matters. Only government‐led approaches can lead to improvements in the quality of teaching and learning for children with FASD and their future life chances. 相似文献

The research reported in this article makes two distinctive contributions to the field of classroom environment research. First, because existing instruments are unsuitable for science laboratory classes, the Science Laboratory Environment Inventory (SLEI) was developed and validated. Second, a new Personal form of the SLEI (involving a student's perceptions of his or her own role within the class) was developed and validated in conjunction with the conventional Class form (involving a student's perceptions of the class as a whole), and its usefulness was investigated. The instrument was cross-nationally fieldtested with 5,447 students in 269 senior high school and university classes in six countries, and cross-validated with 1,594 senior high school students in 92 classes in Australia. Each SLEI scale exhibited satisfactory internal consistency reliability, discriminant validity, and factorial validity, and differentiated between the perceptions of students in different classes. A variety of applications with the new instrument furnished evidence about its usefulness and revealed that science laboratory classes are dominated by closed-ended activities; mean scores obtained on the Class form were consistently somewhat more favorable than on the corresponding Personal form; females generally held more favorable perceptions than males, but these differences were somewhat larger for the Personal form than the Class form; associations existed between attitudinal outcomes and laboratory environment dimensions; and the Class and Personal forms of the SLEI each accounted for unique variance in student outcomes which was independent of that accounted for by the other form. 相似文献

We used data from the American Time Use Survey (years 2003–06) to analyze whether the intensity and duration of high school students' (ages 15–18 years) sports and exercise bouts differed across physical and social environments. Boys' sports and exercise bouts were more likely to reach a vigorous intensity when taking place at school and with friends/acquaintances/other people; whereas girls' sports and exercise bouts were more likely to reach a vigorous intensity when outdoors and alone. For boys and girls, bout durations were greater at school and with friends/acquaintances/other people than in other environments. Overall, environmental influences on the intensity but not duration of sports and exercise bouts appear to differ between boys and girls. 相似文献

Teachers have a central role in developing new learning models in schools. This paper describes a study that explored teachers’ confidence and competence in using Information and Communication Technologies (ICT) as they participated in an ICT development project conducted by an Australian education system in 12 primary schools. The project aimed to develop ICT integrated teaching practices by providing in‐class equipment and teacher professional development in ICT use, curriculum development and teaching strategies. The study used qualitative data from teacher records of Professional Development and Action Learning to identify three of four stages proposed to describe teachers’ ICT learning. Teachers moved from gaining basic ICT skills, to conducting ICT‐focused lessons and eventually appropriate ICT integration. Teachers who progressed to the third stage were able to exploit additional learning opportunities and begin to make fundamental changes to their pedagogy, but needed more time to reach the final stage of challenging existing pedagogical structures. 相似文献

The aim of this study was to build an accurate computer-based model to study the water flow and drag force characteristics around and acting upon the human body while in a submerged streamlined position. Comparisons of total drag force were performed between an actual swimmer, a virtual computational fluid dynamics (CFD) model of the swimmer, and an actual mannequin based on the virtual model. Drag forces were determined for velocities between 1.5 m/s and 2.25 m/s (representative of the velocities demonstrated in elite competition). The drag forces calculated from the virtual model using CFD were found to be within 4% of the experimentally determined values for the mannequin. The mannequin drag was found to be 18% less than the drag of the swimmer at each velocity examined. This study has determined the accuracy of using CFD for the analysis of the hydrodynamics of swimming and has allowed for the improved understanding of the relative contributions of various forms of drag to the total drag force experienced by submerged swimmers. 相似文献
