Aerobic exercise and type a behaviour     

Lori A. Schmied  Hannah Steinberg  Tim Moss  Elizabeth A. Sykes 《Journal of sports sciences》2013,31(5):433-445

The Type A behaviour pattern is a well‐documented, if controversial, risk factor for coronary heart disease. Surprisingly, relatively little work has been reported on ways of modifying this behaviour pattern. Aerobic exercise, with its demonstrated benefits for both cardiovascular reactivity and psychological ‘well‐being’, is a promising treatment. The literature is reviewed and recommendations are made for practical applications and future research.  相似文献

Singing our song: the affordances of singing in an intergenerational,multimodal literacy programme          下载免费PDF全文

Rachel Heydon  Lori McKee  Susan O'Neill 《Literacy》2018,52(3):128-136

This exploratory case study examined the affordances of singing as a multimodal literacy practice within ensembles that featured art, singing and digital media produced in an intergenerational programme that served a class of kindergarten children and community elders. The programme that was set up by the study in collaboration with a rural school and elders' organisation saw participants meet one afternoon a week for most of a school year. Study questions concerned the meaning making and relationship‐building opportunities afforded to the participants as they worked through chains of multimodal projects. Data were collected using ethnographic tools in an elders' home where the projects were completed and in the kindergarten where project content and tools were introduced to the children and extended by the classroom teacher. Themes were identified through the juxtaposition of data in relation to the literature and study questions. Results indicate that singing provided opportunities for participants to form relationships and make meaning as a group while combining modes. Study findings foreground the communicative power of singing and suggest how singing, when viewed through a multimodal lens, might be a potent tool for multimodal literacy learning.  相似文献   

Assessing Precollege Science Education Outreach Initiatives: A Funder's Perspective          下载免费PDF全文

Debra A. Felix  Mark D. Hertle  Jill G. Conley  Lori B. Washington  Peter J. Bruns 《CBE life sciences education》2004,3(3):189-195

We describe an assessment of the collective impact of 35 grants that the Howard Hughes Medical Institute (HHMI) made to biomedical research institutions in 1999 to support precollege science education outreach programs. Data collected from funded institutions were compared with data from a control group of institutions that had advanced to the last stage of review but had not been funded. The survey instrument and the results reveal outcomes and impacts that HHMI considers relevant for these programs. The following attributes are considered: ability to secure additional, non-HHMI funding; institution buy-in as measured by gains in dedicated space and staff; enhancement of the program director''s career; number and adoption of educational products developed; number of related publications and awards; percentage of programs for which teachers received course credit; increase in science content knowledge; and increase in student motivation to study science.  相似文献   

Scaffolding the Appropriation of Self-regulatory Activity: A Socio-cultural Analysis of Changes in Teacher–student Discourse about a Graduate Research Portfolio     

Allyson Fiona Hadwin  Lori Wozney  Oonagh Pontin 《Instructional Science》2005,33(5-6):413-450

This study informs the design and development of pedagogical agents that can flexibly support self-regulation by calibrating guidance to specific phases and facets of self-regulated learning (SRL) as individuals encounter challenges and develop more sophisticated understandings of the task and content. From a socio-cultural perspective of self-regulation, we examine the transition of self-regulatory control from teacher to graduate student during naturalistic instructional conferences. Three goals included (a) examining teacher–student dialogue about a complex task to see if fading actually occurs, (b) examining whether support and fading of support are calibrated to specific phases of the self-regulatory process at a given point in time, and (c) examining techniques used for scaffolding and fading scaffolding directed toward specific phases and facets (behavioral, cognitive, metacognitive and motivational) of the self-regulatory cycle. Findings support a socio-cultural perspective of SRL demonstrating a transition from teacher to student regulation across phases and facets of SRL. The paper concludes with an examination of how our findings can inform the design of computer-based scaffolds that can support SRL.  相似文献

The Effect of School Culture on Science Education at an Ideologically Innovative Elementary Magnet School: An Ethnographic Case Study     

Lori T. Meier 《Journal of Science Teacher Education》2012,23(7):805-822

This ethnographic case study investigated the science practices of teachers at one public elementary magnet school in light of how school culture influenced science curriculum design and instruction. The purpose of the study was to address how school culture impacted the school??s overall treatment of science as a viable content area. Key informant teachers were interviewed to explore their personal beliefs and values, teaching, access to materials, and views of the adopted integrated thematic curriculum model and magnet structure. The resulting data, triangulated with informal observation and artifact collection, were analyzed using a theoretical framework that emphasized five interdependent school culture indicators (values, beliefs, practices, materials, and problems). Findings suggest that the school??s culture adversely influenced the treatment of science.  相似文献   

Power Dynamics and Questioning in Elementary Science Classrooms     

Lori A. Reinsvold  Kathryn F. Cochran 《Journal of Science Teacher Education》2012,23(7):745-768

We describe the dynamic discourse interactions between a teacher and her students in a third-grade science classroom. We focused on how the teacher and students initiate, prompt, respond, and provide feedback; use questioning and power strategies; and how questions are associated with power dynamics. We relate the consequences of teacher use of power to the engagement of student with subject matter. Two classroom sessions were observed and teacher?Cstudent interactions audio recorded. Data were transcribed and a method was developed for analyzing teacher-student interactions, power dynamics, and types of questions asked. Results revealed that teacher talk was twice as frequent as students?? talk; questions were primarily closed-ended and task-oriented; and students asked few questions. The teacher exercised power by keeping activities organized and conventional, and utilizing subject matter. The developed methods showed us the complexity of question and power dynamics in classroom discourse and have implications for professional development and research.  相似文献   

Trends in culturally relevant interface design features for Latino Web site users     

Lori L. Sachau  Susan R. Hutchinson 《Educational technology research and development : ETR & D》2012,60(6):1033-1050

There is a lack of published research on designing Web-based instruction for the adult U.S. Latino population. Instructional designers need guidance on how to design culturally relevant learning environments for this audience, particularly for Latino people from Mexican heritage. The authors used content analysis to investigate the extent to which 20 U.S. state food stamp Web sites and 20 Mexican state government Web sites contained culturally relevant interface features targeted at the Spanish-speaking Latino population. Web sites were coded for 10 features distilled from Hofstede??s work on cultural differences. Results indicated that more culturally and linguistically relevant features, including Hofstede??s dimensions of collectivism, power distance, and uncertainty avoidance, as well as adequacy of information in Spanish, were found on Mexican than on U.S. Web sites. The findings suggest that Hofstede??s cultural dimensions theory might provide a useful framework for designing Web-based resources for the adult U.S. Spanish-speaking Latino population and provides additional evidence to further investigate if Web-based interface features tailored for U.S. Latino Web users motivate users, strengthen communication, and promote learning.  相似文献   

Preserving respectability or blatant disrespect? A critical discourse analysis of the Morehouse Appropriate Attire Policy and implications for intersectional approaches to examining campus policies     

Lori D. Patton 《International journal of qualitative studies in education》2014,27(6):724-746

In this paper, I conduct a critical discourse analysis of the Morehouse College Appropriate Attire Policy and discuss how issues of race, gender, and sexuality converge to reveal both overt and hidden meanings embedded in the policy. I also consider how power is used towards “other” black college men who neither fit neatly into prescribed gender norms, nor foster representations of “good” black men. I situate this critical policy analysis in the context of two ideas: bipolar masculinity and the politics of respectability, and offer implications for the use of intersectional frames in scholarship and research on men and institutional policies.  相似文献
