The ethics of polyvocal ethnography: empowering vs. textualizing children and teachers     

Joseph Tobin  Dana Davidson 《International journal of qualitative studies in education》2013,26(3):271-283

Polyvocal approaches allow researchers and informants to interact on a more equal footing and informants’ voices to be heard in the final text. But research methods intended to empower informants also can be a source of unanticipated authorial power ‐ the power to confront informants with unsolicited self‐reflections and to textualize people's lives and words. The authors reflect on those ethical dilemmas in this article.  相似文献   

The role of cognitive factors in chemistry achievement     

Sarath Chandran  David F. Treagust  Kenneth Tobin 《科学教学研究杂志》1987,24(2):145-160

Evidence from the research literature suggests that a variety of cognitive factors is responsible for chemistry achievement. This investigation examined the role of four cognitive factors, namely, formal reasoning ability, prior knowledge, field dependence/ independence, and memory capacity on achievement in chemistry as measured by tests of laboratory application, chemical calculations and content knowledge. The sample comprised grade 11 students from eleven high schools who were following the same chemistry syllabus. The results indicated that prior knowledge and formal reasoning ability were each statistically significantly related to variation in chemistry achievement. Field dependence/independence and memory capacity played no significant role in chemistry achievement.  相似文献

Vicarious learning from dialogue and discourse     

Richard Cox  Jean Mckendree  Richard Tobin  John Lee  Terry Mayes 《Instructional Science》1999,27(6):431-458

This study examined learning in the domain of sentence parsing and syntax treediagram construction. The aim of the study was to assess whether subjects could learn vicariously from recordings of interactions between a previous student and a tutor.Four intervention conditions and a control condition were compared. Subjects in a dialogue group (DL) read printed tutorial notes and subsequently vicariously viewed dynamic (animated) recordings of tree diagrams being constructed by a previous student in the presence of a tutor.The discourse (DI) condition was similar except that subjects viewed recordings of tree diagrams being constructed by a tutor who concurrently verbalised instructional discourse.In a third condition (DO), subjects viewed tree-diagram construction animation clips which were not annotated with either dialogue or discourse. In a linear text (LT) condition, subjects were given only printed tutorial notes. A control (CO) condition involved pre and post testing without any intervention.Results indicated that the dialogue condition was as effective as the discourse condition. This provides support for contention that re-usable dialogue is a useful resource for the vicarious learner. Another finding was that un-annotated animated diagrams were surprisingly effective. Several reasons for their effectiveness are suggested from the literature on instructional animations.  相似文献   

Teaching physics to prospective elementary teachers: Bridging gaps or widening chasms     

Professor Kenneth Tobin  Wolff-Michael Roth  Sabitra Brush 《Research in Science Education》1995,25(3):267-281

The education of prospective Elementary and Early Childhood (E&EC) teachers to teach science has been an on-going challenge for science teacher educators. Accordingly, a course in physical science was planned and implemented especially for prospective E&EC teachers. The purpose of this study was to understand the nature of the enacted curriculum and about the forces which constrained its evolution. Miller, the teacher of the course, had no prior experience in teaching prospective E&EC teachers and many of his experiences as a university level teacher were based on his teaching of physics majors. These experiences shaped his approach to teaching the course as did his years as a basketball coach. Miller was an expert in physics and constructed his role as teaching students significant scientific truths. Miller saw the purpose of the course as being to educate the students in science, not to prepare them to teach science. He was unwilling to address the goals of students that were oriented strongly toward becoming better teachers. The beliefs of the teacher constrained the enacted curriculum to an extent that gaps between the needs of students and the enacted curriculum were wider at the end of the course than they were at the beginning. Armstrong College In my opinion I think I failed completely, but I am quite happy with what I am trying to do. I just don't think I executed it well. So I was pretty unhappy with the whole experience in terms of the results, but I was not unhappy with the experience in terms of whether it was worth doing. I think it is important in science to develop free-thinking and being able to come to conclusions. Science is being able to reflect on the human condition, and being able to think about things you don't know about. (Miller)  相似文献   

Improving science teaching practices     

Kenneth Tobin 《International Journal of Science Education》2013,35(5):475-484

A review of research relating to the problem of using research findings to improve classroom practice is presented. There are two aspects to this problem: familiarizing teachers with relevant research and identifying an aspect of teaching that needs to be improved. Research conducted in local settings appears to have most relevance to teachers and is more likely to be accepted by them. Studies indicate that research can have an impact on practice as long as teachers are involved in identification of problems in their class and are provided with a context in which they can learn the strategies to be implemented and understand why they are likely to improve teaching. Teachers need opportunities to practice teaching in peer groups where errors can be made without jeopardizing student learning; receive performance feedback; practice the strategies in their own classes; observe others teach; and discuss teaching with others. Strategy analysis, coaching and peer coaching are techniques which enable most of these criteria to be met and to facilitate science teaching improvement.  相似文献

Is Blindness a Handicap?     

Michael J. Tobin 《British Journal of Special Education》1998,25(3):107-113

Michael J. Tobin, Professor of Special Education at The University of Birmingham, argues that the handicapping effects of blindness are specific to certain educational and social contexts. These situations can be identified: the most substantive difficulties being the availability of convergent and complementary information through the various sensory channels, and the depressed speeds of information processing.  相似文献   

Movement patterns and physical strain during a novel, simulated cricket batting innings (BATEX)   总被引：1，自引：1，他引：0  

Houghton L  Dawson B  Rubenson J  Tobin M 《Journal of sports sciences》2011,29(8):801-809

A simulated cricket batting innings was developed to replicate the physical demands of scoring a century during One-Day International cricket. The simulated innings requires running-between-the-wickets across six 5-over stages, each of 21 min duration. To validate whether the simulated batting innings is reflective of One-Day International batting, movement patterns were collected using a global positioning system (GPS) and compared with previous research. In addition, indicators of physical strain were recorded (heart rate, jump heights, sweat loss, tympanic temperature). Nine club cricketers (mean ± s: age 20 ± 3 years; body mass 79.5 ± 7.9 kg) performed the simulated innings outdoors. There was a moderate trend for distance covered in the simulated innings to be less than that during One-Day batting (2171 ± 157 vs. 2476 ± 631 m · h?1; effect size = 0.78). This difference was largely explained by a strong trend for less distance covered walking in the simulated innings than in One-Day batting (1359 ± 157 vs. 1604 ± 438 m · h?1; effect size = 1.61). However, there was a marked trend for distance covered both striding and sprinting to be greater in the simulated innings than in One-Day batting (effect size > 1.2). Practically, the simulated batting innings may be used for match-realistic physical training and as a research protocol to assess the demands of prolonged, high-intensity cricket batting.  相似文献   

The contribution of reading comprehension ability and meta‐cognitive control to the development of studying in adolescence     

Stephen T. Peverly  Karen E. Brobst  Kerri S. Morris 《Journal of Research in Reading》2002,25(2):203-216

This study investigated the developmental changes in the contributions of comprehension ability and the meta‐cognitive control of several study strategies (selection, memory, monitoring) to competence in studying among average and above‐average seventh and eleventh‐grade students. Results indicated that the ability to comprehend and meta‐cognitive control of study strategies were related to the recall of information at both ages. However, meta‐cognitive control was clearly more important to the older students than it was to the younger students. These data suggest that future research on the development of studying should focus on students’ use of the strategies of memory and monitoring.  相似文献
