O. W. H.—Conversationalist extraordinary     

Egbert S. Oliver 《Communication quarterly》2013,61(4):12-13

For two decades, Basil Bernstein has been a major contributor to the literature on language and society. A framework is presented/or casting Bernstein's work at a level of abstraction appropriate for assessing communicative competence. The concepts of cultural matrix, primary social experience, and role and situation repertoires are central to this framework, it is argued that analysis of four role constellations and four aspects important to social role formation are a good basis from which to describe and explain any person's range of communicative competencies. Research strategies for investigating communicative competence are suggested.  相似文献   

Enhancing the Student Experiment Experience: Visible Scientific Inquiry Through a Virtual Chemistry Laboratory     

Dermot Donnelly  John O’Reilly  Oliver McGarr 《Research in Science Education》2013,43(4):1571-1592

Practical work is often noted as a core reason many students take on science in secondary schools (high schools). However, there are inherent difficulties associated with classroom practical work that militate against scientific inquiry, an approach espoused by many science educators. The use of interactive simulations to facilitate student inquiry has emerged as a complement to practical work. This study presents case studies of four science teachers using a virtual chemistry laboratory (VCL) with their students in an explicitly guided inquiry manner. Research tools included the use of the Inquiry Science Implementation Scale in a ‘talk-aloud’ manner, Reformed Teaching Observation Protocol for video observations, and teacher interviews. The findings suggest key aspects of practical work that hinder teachers in adequately supporting inquiry and highlight where a VCL can overcome many of these difficulties. The findings also indicate considerations in using the VCL in its own right.  相似文献   

Pushing the boundaries of self-directed learning: research findings from a study of u.lab participants in Scotland     

Eva Pomeroy  Keira Oliver 《International Journal of Lifelong Education》2013,32(6):719-733

ABSTRACT

This article reports on the research findings from a qualitative study of adult learners in Scotland taking part in a u.lab MOOC. As a new phenomenon in adult learning, u.lab has been extremely popular yet, at present, there exists little empirical data about either the process or outcomes of the learning experience. This study aims to provide a starting point for further study of u.lab and other emergent trends in adult learning. Here, the accounts of 12 women and men participating in u.lab were analysed using a grounded theory framework. The inductive nature of this approach allowed us to build up a picture of participant experience. Of significance in the findings were participants’ relationship to course content, experience of learning in community and engagement in shaping the learning experience. We draw on Illeris’ model of the learning field to deepen our understanding of participant experience and to illustrate how the particular constellation of content, incentive and interaction dimensions of learning in u.lab creates a learning space where the possibility for self-direction and self-organisation is extended beyond existing practice.  相似文献   

THE IMPORTANCE OF SOCIOEDUCATIONAL RELATIONSHIPS IN UNIVERSITY PROGRAMS FOR OLDER ADULT STUDENTS     

Luís Ballester  Carmen Orte  Marti X. March  Josep Lluís Oliver 《Educational gerontology》2013,39(4):253-261

ABSTRACT

In this paper we consider that, to a great degree, educational quality is insured through successful educational and social-relationship strategies developed among educators and their older adult students. Proposals to improve educational quality should be considered within the unique context of each university's mission and goals. Otherwise, the same measures used in different institutions may lead either to progress or to educational and social regression. Much depends on the conditions under which programs are implemented, and the way they are perceived by participants in the educational process.  相似文献

Chinese and Australian Year 3 Children's Conceptual Understanding of Science: A multiple comparative case study     

Ying Tao  Mary Colette Oliver  Grady Jane Venville 《International Journal of Science Education》2013,35(6):879-901

Children have formal science instruction from kindergarten in Australia and from Year 3 in China. The purpose of this research was to explore the impact that different approaches to primary science curricula in China and Australia have on children's conceptual understanding of science. Participants were Year 3 children from three schools of high, medium and low socio-economic status in Hunan Province, central south China (n?=?135) and three schools of similar socio-economic status in Western Australia (n?=?120). The students' understanding was assessed by a science quiz, developed from past Trends in Mathematics and Science Study science released items for primary children. In-depth interviews were carried out to further explore children's conceptual understanding of living things, the Earth and floating and sinking. The results revealed that Year 3 children from schools of similar socio-economic status in the two countries had similar conceptual understandings of life science, earth science and physical science. Further, in both countries, the higher the socio-economic status of the school, the better the students performed on the science quiz and in interviews. Some idiosyncratic strengths and weaknesses were observed, for example, Chinese Year 3 children showed relative strength in classification of living things, and Australian Year 3 children demonstrated better understanding of floating and sinking, but children in both countries were weak in applying and reasoning with complex concepts in the domain of earth science. The results raise questions about the value of providing a science curriculum in early childhood if it does not make any difference to students' conceptual understanding of science.  相似文献

Identification of Accelerometer Nonwear Time and Sedentary Behavior     

Melody Oliver  Hannah M. Badland  Grant M. Schofield  Janine Shepherd 《Research quarterly for exercise and sport》2013,84(4):779-783

Abstract

This study was designed to investigate the swimming endurance trainability of smokers as compared to nonsmokers. Nonsmokers (N = 47) and smokers (N = 34) of college age were selected from intermediate swimming classes and timed while swimming distances of 100 yd. and 200 yd. prior to participation in an 8-week training program. After 4 weeks of training, swimming times were again recorded for these same distances. At the end of eight weeks, swimming times were taken for distances of 100, 200, and 400 yards. The mean changes of both smokers and nonsmokers during the pretraining to 4-week period, the 4-week to 8-week period, and the pretraining to 8-week period were all significant at the .05 level. However, no significant differences were found between the mean swimming times of smokers and nonsmokers for any of the pretraining, 4-week, or 8-week distances.  相似文献   

Accelerometry to Assess Preschooler's Free-Play: Issues with Count Thresholds and Epoch Durations     

Melody Oliver  Grant M. Schofield  Philip J. Schluter 《Measurement in physical education and exercise science》2013,17(4):181-190

This study examines the utility of current accelerometer threshold definitions and epoch durations for physical activity intensity classification in preschool-aged children. Using video footage of children engaged in active play, directly observed 1-sec epoch physical activity intensity scores were derived from a modified version of the Children's Activity Rating Scale, averaged into 15-sec epochs (corresponding to the accelerometer scale), and compared to accelerometer-measured classifications. Overall, 6,540 individual 1-sec epochs were captured and classified from six children, yielding 429 time-matched 15-sec epoch physical activity intensity classifications from both methods. Children participated in 25 distinct physical activity behaviors and spent 75% of free-play in one intensity level for ≤5 sec. The maximum amount of time spent participating in an activity prior to changing activity intensity was 98 sec. Agreement between methods was generally poor (overall: κ = .22; child range: κ = .00 to .66), and the difference between methods was significantly asymmetrical (McNemar's test overall: p = .01). Accelerometer thresholds and epoch durations used to classify preschoolers' physical activity intensity yielded biased estimates in the current study. Further investigation is necessary to establish optimal physical activity measurement methods with this population.  相似文献   

Images of the Body from Popular Culture: Engaging Adolescent Girls in Critical Inquiry     

Kimberly L. Oliver 《Sport, Education and Society》2013,18(2):143-164

The purpose of this paper is to highlight how I use images from teen magazines to engage girls in critical inquiry about the body. This process is about co-constructing bodily knowledge and reflecting critically on this knowledge. The analysis is broken into three main parts: (a) tapping girls' interests; (b) helping girls name how they experience their bodies; and (c) using images to critique dominant stories of the body. Within each of these sections, I will foreground the process by looking at the curricular tasks as well as the verbal engagement through which the girls and I negotiated the tasks together. The data are used to illustrate the pedagogical possibilities of engaging girls in critical inquiry on body. I conclude the paper by discussing the pedagogical possibilities for studying the body with adolescent girls that emerged and reflect critically on the struggles involved in the process of engaging girls in critical inquiry.  相似文献
