A survey of undergraduate students examined how students’ beliefs about their problem-solving styles and abilities (including avoidant style, confidence, and personal control in problem-solving) influenced their perception and selection of sources, as reflected in (1) perceived characteristics of sources, (2) source characteristics considered important as selection criteria, and (3) frequency of source use. The findings can be helpful in designing bibliographic instruction and information literacy programs. 相似文献
This article presents the results of qualitative research carried out among Polish centenarians who have not experienced loneliness. Objectives: An attempt to find factors protecting against loneliness. A total of 17 cases were included in the research. Method: A collective case study (Stake, 2009) with in-depth interview was applied to the research carried out by the authors. The results show that activity together with personal characteristics (lifelong optimism) allows the building of positive social relationships and contribute to protection against loneliness among the oldest old. Discussion and Implications: The centenarians interviewed experienced many traumatic events in their lives and still they did not know the feeling of loneliness. The cases researched were diverse with respect to social and economic status, health condition, and family status but the common aspect was their lifetime activity and their high level of optimism. The lifelong activity of the respondents allowed them to build social relationships and establish new acquaintanceships, both intra- and intergenerationally. Promoting examples of “positive long-livers” may play preventive role and contribute to the quality of life in late old age, and as societies are ageing, the results are also important for public health. 相似文献
We used communication infrastructure theory to investigate oral health beliefs and behavior among young adults in Appalachian Kentucky. We conducted 7 focus groups with 67 participants who reported poor oral health behavior, but this was not necessarily the result of poor oral health knowledge. Participants identified several sociocultural factors affecting their oral health, including lack of oral health prioritization among older generations, and risky health behaviors that competed with good oral health. These sociocultural factors create a context in which standard oral health recommendations are commonly seen as excessive. Participants described various responses to the poor oral health in the region, including fatalism and a distrust of dentists, and that oral healthcare professionals may be using potentially problematic communication tactics. Practical implications for designing effective oral health promotion campaigns in the region and theoretical implications for developing social-contextual frameworks of oral health promotion are discussed. 相似文献
We describe a two year empirical investigation of three‐ and four‐year‐old children's uses of technology at home, based on a survey of 346 families and 24 case studies. Using a socio‐cultural approach, we discuss the range of technologies children encounter in the home, the different forms their learning takes, the roles of adults and other children and how family practices support this learning. Many parents believed that they did not teach children how to use technology. We discuss parents' beliefs that their children ‘pick up’ their competencies with technology and identify trial and error, copying and demonstration as typical modes of learning. Parents tend to consider that their children are mainly self‐taught and underestimate their own role in supporting learning and the extent to which learning with technology is culturally transmitted within the family. 相似文献
Recent science educational policy reform efforts call for a shift toward practice-focused instruction in kindergarten–Grade 12 science education. We argue that this focus on engaging students in epistemic practices of science opens up new possibilities for the design of learning environments that support the stabilization of learners’ science-linked identities. Learning environments often assume that youth come to them without relevant identity resources to contribute or that the learning environment has no bearing on the disciplinary identification of individuals. We conducted this research while developing a year-long course to teach high school biology by engaging youth in interest-driven projects focused on contemporary topics. We explored how engaging youth in the epistemic practices of science in culturally expansive ways supported their science-linked identification. We propose a model grounded in social practice theory that describes aspects of students’ stabilization of disciplinary identities. We found that (a) deepening participation in scientific practices is linked to whether or not youth have opportunities to coordinate their engagement with their existing identities; and (b) material, relational, and ideational identity resources and qualities of the learning environment mediate how youth stabilize disciplinary identities in interactional moments. 相似文献
Breast asymmetry is common in females, despite a similar driving force; dynamic activity may result in asymmetrical breast motion. This preliminary study investigated how breast categorisation (left/right or dominant/non-dominant) may affect breast support recommendations and its relationship with breast pain. Ten females ran on a treadmill at 10 kph in three breast supports (no bra, everyday bra, sports bra). Five reflective markers on the thorax and nipples were tracked using infrared cameras (200 Hz) during five running gait cycles in each breast support. Multiplanar displacements of both breasts were calculated relative to the thorax. Although the maximum individual participant difference was 2.4 cm (mediolaterally) between the left and right breast, no left/right differences were found in any direction or support condition. Notably, correlations between breast pain and anterioposterior breast displacement were stronger with the left breast (r = 0.614) and moderate with the right breast (r = 0.456). Following participant categorisation according to the greatest magnitude of superioinferior breast displacement (dominant breast), results showed significant differences in displacement for all directions across different breast supports. When using breast kinematic data to examine relationships with breast pain or to recommend breast support requirements, data on both breasts should be collected. 相似文献
Recommendations for breast support, dynamic breast pain assessment, and implications for sports performance have been made within breast biomechanics research; however, these studies have been based upon short exercise protocols (2–5 min). The aim of this study was to investigate the effect of breast support on multiplanar breast kinematics over a 5-kilometre run. Ten female participants (34D or 32DD) conducted two 5-kilometre runs, in a low and high breast support. Relative multiplanar breast kinematics were averaged over five gait cycles at six intervals of a 5-kilometre run. Increases in multiplanar breast kinematics were reported from the start to the end of the run, with the greatest rate of increase in breast kinematics reported within the first two kilometres of running. The greatest relative increases in breast range of motion (34%), velocity (33%), and acceleration (41%) were reported in the superioinferior direction at the fifth kilometre (33 min of running) in the high breast support. Key findings suggest that the run distance, and therefore run duration, employed for both fundamental research and product validation protocols should be carefully considered and it is suggested that running protocols for assessing breast biomechanics should exceed 7 min. 相似文献
The inclusion of games in mathematics programmes is widely believed to foster the enjoyment of mathematics. The focus of this paper is on fluctuations in emotional climate during the playing of whole-class mathematics games. A multimethod approach drawing on the sociology of emotions was employed to explore changes in the classroom emotional climate that were associated with game playing. The event-oriented inquiry was conducted with two teachers and a class of 10- to 13-year-olds in a New Zealand classroom during mathematics sessions. Over a series of eight mathematics lessons, there were three noticeable fluctuations in emotional climate, all of which occurred during whole-class games. Our analysis of these three events identified a successful interaction with dramatic emotional energy associated with a positive emotional climate, a successful interaction with undramatic emotional energy associated with positive emotional climate, and an unsuccessful interaction associated with negative emotional climate with interactional repair. The third event also illustrated how the incomplete nature of a game’s rules can provide an opportunity for a negative emotional climate to be associated with game playing. The taken-for-granted wisdom that whole-class mathematics games can enhance emotional aspects of a classroom learning environment is supported by some of our evidence.
The lived experiences of young people are becoming increasingly marginalised within the narrowly defined curricula of neoliberal contexts. Many young people are also cast within the media according to deficit discourses of youth, which contributes to the fragmentation of communities and the limitation of interaction between generations. This article describes a film project in which young people living in an ex-mining community in the Midlands of England worked in and with their community to create a representation of where they live. As part of the process, the young filmmakers did more than connect to other people’s memories as repositories of information; both as process and as product, their film can be seen to connect shared narratives of people and place, across time and space. We argue that this project offers a timely opportunity to reflect upon the ways in which we understand learning in and out of English classrooms. 相似文献
