The objective of this systematic review and meta-analysis was to evaluate the effectiveness of peers to deliver programs or encourage older people to be physically active and improve physical outcomes. Peer reviewed articles published in English between January 1976 and June 2016, retrieved from six databases according to the predefined inclusion criteria were included. Where possible results were pooled and meta-analyses conducted. Eighteen articles were included in the review, a total of 3,492 intervention participants, average age 66.5 years and 67.1% were female. Overall, study quality was medium to high. Interventions mainly included resistance, flexibility and cardiovascular training, however there was one aquatic exercise group. Eight studies were delivered by peers and five utilised peer support, which included advice and being positive but was not directly linked to an exercise intervention. While 16 of the 18 studies reported improvement in levels of physical activity and/or noted physical benefits by peer involvement, the meta-analyses findings supported the control groups for the six-minute-walk-test and the timed-up-and-go test. Findings from this review suggest exercise programs involving peers can promote and maintain adherence to exercise programs. However, results were inconclusive as to whether peers have a positive effect on improving older people’s physical function. 相似文献

The purposes of this study were to examine: 1) the potential muscle-specific differences in voluntary electromechanical delay (EMD) and relaxation electromechanical delay (R-EMD), and 2) the effects of intensity on EMD and R-EMD during step incremental isometric muscle actions from 10 to 100% maximal voluntary isometric contraction (MVIC). EMD and R-EMD measures were calculated from the simultaneous assessments of electromyography, mechanomyography, and force production from the vastus lateralis (VL), vastus medialis (VM), and rectus femoris (RF) during step isometric muscle actions. There were no differences between the VL, VM, and RF for the voluntary EMDE-M (onsets of the electromyographic to mechanomyographic signals), EMDM-F (onsets the mechanomyographic to force production), or EMDE-F (onsets of the electromyographic signal to force production) as well as R-EMDE-M (cessation of electromyographic to mechanomyographic signal), R-EMDM-F (cessation of mechanomyographic signal to force cessation), or R-EMDE-F (cessation of electromyorgraphic signal to force cessation) at any intensity. There were decreases in all EMD and R-EMD measures with increases in intensity. The relative contributions from EMDE-M and EMDM-F to EMDE-F as well as R-EMDE-M and R-EMDM-F to R-EMDE-F remained similar across all intensities. The superficial muscles of the quadriceps femoris shared similar EMD and R-EMD measurements. 相似文献

Teaching and learning in digital environments: The resurgence of resource-based learning 总被引:4,自引:0,他引:4
Janette R. Hill Michael J. Hannafin 《Educational technology research and development : ETR & D》2001,49(3):37-52
The digital age has not simply changed the nature of resources and information; it has transformed several basic social and
economic enterprises. Contemporary society—the settings where we live, work, and learn—has likewise changed dramatically.
Both the amount of information and access to it have grown exponentially; a significant potential for using varied resources
in numerous ways for instruction and learning has emerged. However, several issues related to the educational uses of varied
resources (e.g., people, place, things, ideas) must be addressed if we are successfully to implement resource-based learning
environments. In this paper, we trace the changing nature of resources and perspectives in their use for learning in the digital
age, describe the overarching structures of resource-based learning environments, and identify key challenges to be addressed. 相似文献

Maximising meaning: creating a learning environment for reading comprehension of informative texts from a Vygotskian perspective 总被引:1,自引:0,他引:1
Yvonne van Rijk Monique Volman Dorian de Haan Bert van Oers 《Learning Environments Research》2017,20(1):77-98
Sociocultural theories based on the work of Vygotsky have been increasingly influential in educational sciences. Developmental education (DE) is a pedagogical approach based on Vygotskian theory that has inspired primary schools in the Netherlands to change the learning environment innovatively in a comprehensive way. In this article, we focus on the learning environment for reading comprehension of informative texts in upper-primary grade classrooms in DE. Our aim is to contribute to a more profound understanding of the characteristics of learning environments that are inspired by a Vygotskian approach and that are conducive to reading comprehension of informative texts. Five fourth-grade expert DE teachers participated in a multiple case study aimed at describing and analysing these characteristics for the domain of reading informative texts. Data were collected over a period of six to eight weeks for each teacher and consisted of videotaped interviews, classroom observations and documents. We conclude that DE learning environments are focused on maximising meaning from text for students. This is achieved by organising learning on the basis of emergent goals within students’ participation in sociocultural practices. 相似文献

New systems that seek to evaluate teachers with regard to their classroom quality often rely on observation instruments that capture general instructional pedagogies. However, decades of research suggest that content-specific dimensions of instruction also are important to differentiate teachers and improve student outcomes. We explore the degree of overlap between a general and a content-specific instrument when capturing upper elementary teachers’ mathematics instruction. To do so, we conducted exploratory and confirmatory factor analyses on data from more than 2,000 videotaped lessons scored using both the Classroom Assessment Scoring System, a general instrument, and the Mathematical Quality of Instruction, a content-specific instrument. Findings indicate that there is some overlap between instruments but that preferred factor structures include both general and content-specific practices. 相似文献

This review of the literature focused on three decades of research related to precollege student understandings about the nature of science. Various interpretations of what aspects characterize the nature of science were examined, revealing an agreement among scientists, science educators, and those involved in policy-making arenas that the nature of science is multifaceted and an important component of scientific literacy. A summary of the research regarding the adequacies of student conceptions about the nature of science revealed inconsistent results. Although the majority of studies show that student understandings are less than desirable, there is research that indicates that student conceptions are acceptable. Research on the impact of instructional materials and techniques on student understandings was also reviewed. The effects of language in science instruction, the content emphasis of instructional materials, integrated science curricula, and instruction in general were curricular variables found to have a negative impact on student understandings about the nature of science. Empirical evidence about the success of innovative instructional materials and techniques designed to facilitate more adequate understandings of the nature of science is needed. 相似文献

To what extent do teachers use questions to encourage deeper thinking and elicit fuller responses? How do teachers use the levels of questions and wait time as a teaching technique? How do teachers make space for students to talk together so that their thoughts are visible to other students? This article seeks to provide answers to these important questions through a review of the literature that begins with a study of the history of questioning, and then turns to the following topics: developing higher level thinking through questioning strategies; the role of wait time within the context of classroom climate and peer interactions; and higher order questioning strategies aligned with student achievement in reading and language arts. Although the author's frame of reference for how these issues play out is within the context of a school where students’ ability to articulate understanding and their own point of view is purposefully promoted and highly valued, the insights will have broad applicability across a full spectrum of schools. 相似文献

To date, very few studies have explored the incidence of motor impairment amongst children with social, emotional and behavioural difficulties (social, emotional and mental health (SEMH); formerly SEBD in England). Following research that suggests an increase in motor difficulties in young children and adolescents with SEMH difficulties, this study compares profiles of motor ability using the Movement ABC-2 assessment in children attending a specialist SEMH primary school with a typically developing comparison group and children with a diagnosis of developmental coordination disorder. We report an increased prevalence of borderline or clinically significant motor impairment amongst children with SEMH difficulties compared to the comparison group, with 44% of the SEMH special school sample falling within these ranges. We suggest that bearing in mind the increased likelihood for motor impairment is important in SEMH education, as it has likely impact on classroom functioning and ability and motivation to take part in socially and academically relevant activities. 相似文献

Against a rapidly changing policy landscape for teacher education, exacerbated by ‘Brexit’ in the UK, findings are presented from an electronic survey of 272 higher-education based teacher educators in England, the Republic of Ireland and Scotland about their experiences of, and priorities for, professional learning. While the data generated were mainly quantitative data, qualitative features were embedded within the survey design. Both types of data have been used to draw out complexities that emerge when exploring a professional group of educators responsible for the preparation of a future generation of teachers. The findings are presented and discussed in relation to the professional demographics of the sample, research expectations placed on them and teacher educators’ priorities for professional learning. Given the unique occupational position of teacher educators, their importance in the quality of teacher education and the lack of formal focus on their professional development, our starting point for teacher educators’ professional development lies in their practice situated and positioned within global, regional, national and local policy contexts. 相似文献
