Students’ talk about identity presents a challenge to teachers and researchers, as its social meaning is often ambiguous and indeterminate. This article adapts the concept of transgressive semiotics, originally developed in relation to linguistic landscapes, to explore moments when unexpected uses of language, involving some mismatch of speaker, utterance, and intention, were taken up in ways that offered profound insight into issues of racial identification and belonging in the U.S.-Mexico borderlands. Close analysis of interactional, observational, and interview data from a linguistic ethnographic study of a high school science classroom in southern Arizona shows that students monitored their own and others’ talk for out-of-place utterances, including stylized speech, errors, and gaffes. Students used these semiotic transgressions as opportunities to give voice to their lived experience of being Mexican in a social context characterized by widespread monitoring and surveillance.  相似文献

The Digital History and Pedagogy Project (DHPP) is an interpretive/pedagogical collection of Web-based historical resources designed for use in inquiry-based learning in high school and university classrooms. It has been created by faculty and graduate students at a large urban college of education. This paper provides a rationale for the project rooted in current literature; presents a theoretical framework for this and other similar projects; and describes five current digital historical resources (DHRs) within the context of our framework.  相似文献

Three experiments investigated the effects of rime consistency on reading and spelling among developing readers ranging in age from 7 to 11 years. Experiment 1 found that children read words with inconsistent feedforward mappings between orthography and phonology (O → P) less accurately than consistent words. OP consistency interacted with chronological age, word frequency and age-of-acquisition (AoA). The effect of OP consistency on reading was larger for younger children than for older children and OP consistency had an effect for low frequency words and late-acquired words only. Experiment 2 found an effect of feedforward consistency between phonology and orthography (P → O) on children’s spelling but no interaction between PO consistency and AoA. Experiment 3 showed that the effects of feedforward consistency are independent of feedback consistency. Our results challenge models of reading and spelling that assume feedforward consistency effects are influenced by the frequency of exposure to words only and we suggest that interactions between consistency and AoA depends on the ratio of consistent to inconsistent OP mappings.  相似文献

The growth of fantasy sports into a multi-billion dollar industry has made it an important component of the sports industry. Sport leagues must acknowledge the impact fantasy sports have on the way its participants consume their sport. This study examines the impact of fantasy football on the consumption of NFL-related products and services using an adapted version of the attitude/behavior model developed [Fazio, R. H., Powell, M. C., & Herr, P. M. (1983). Toward a process model of the attitude–behavior relation: Accessing one's attitude upon mere observation of the attitude object. Journal of Personality and Social Psychology, 44(4), 723–735]. Using qualitative methods, the data indicate that fantasy football participants utilized various media sources, specifically the Internet, television, cellular telephones, and a variety of print media, at much higher levels as a result of their interest and participation in fantasy football. Further, contrary to previous literature on fan loyalty, team and player outcomes were found to alter perceptions towards a favorite team or a fantasy team.  相似文献

The reliability and validity of the PLAYfun and PLAYbasic tools were assessed. The PLAYfun, PLAYbasic, Canadian Agility and Movement Skill Assessment (CAMSA) obstacle course, and Physical Activity Questionnaire for Children (PAQ-C) were administered to children (aged 8–14 years) in two remote Canadian communities. Inter-rater reliability of the PLAYfun and PLAYbasic were good-to-excellent for average measures and moderate-to-good for single measures. The PLAYfun subscales were poor-to-excellent for average and single measures. The internal consistency of the PLAYfun tool was good, PLAYbasic was poor-to-good, and the individual subscales were poor-to-good. Convergent validity was moderate-to-large for the PLAY tools and CAMSA obstacle course, and small-to-moderate for the PLAY tools and the PAQ-C, and small-to-moderate for the PLAY tools and age. For children and youth in northern Canada, the motor competence aspect of physical literacy is most accurately assessed using the complete PLAYfun tool and two raters.  相似文献

Abstract

This article compares the newspaper coverage of Internet access in public libraries across two countries, Canada and Singapore. The aim is to discover some of the main concerns and themes that the press identifies with libraries, noting the differences between the two countries in this regard, and then to provisionally link these differences to certain structural characteristics of their respective societies and states. To achieve these aims I compare press coverage produced in terms of dates of publication, discourse producers, and discourse content. Implications of the findings for libraries and librarians are discussed.  相似文献

We describe the physiological characteristics of amateur outrigger canoe paddlers. Twenty-one paddlers (13 males, 8 females) were evaluated for body stature, aerobic power, muscular strength and endurance, peak paddle force, flexibility and 250 m sprint paddle performance at the end of the outrigging season. The mean variables ( - s) for the males were: age 27 - 9 years, height 175 - 5 cm, body mass 80 - 5 kg, arm span 178 - 7 cm, sitting height 100 - 2 cm, aerobic power 3.0 - 0.4 l·min-1, maximum bench press strength 85 - 19 kg, right peak paddle force 382 - 66 N and left peak paddle force 369 - 69 N. For the females, these were: age 26 - 6 years, height 168 - 5 cm, body mass 70 - 8 kg, arm span 170 - 5 cm, sitting height 97 - 3 cm, aerobic power 2.3 - 0.5 l· min-1, maximum bench press strength 47 - 10 kg, right peak paddle force 252 - 63 N and left peak paddle force 257 - 60 N. Analysis of variance revealed diff erences (P ? 0.05) between the dominant and non-dominant sides of the body for peak paddle force, isokinetic internal and external rotation, and flexion and extension torque of the shoulder joint. The outrigger canoe paddlers were generally within the range of scores found to describe participants of other water craft sports. Outrigger canoeists should be concerned with the muscular strength imbalances associated with paddling technique.  相似文献

Abstract

Analysis of variability and progression in performance of top athletes between competitions provides information about performance targets that is useful for athletes, practitioners, and researchers. In this study, 724 official finals times were analysed for 120 male and 122 female Paralympic swimmers in the 100-m freestyle event at 15 national and international competitions between 2004 and 2006. Separate analyses were performed for males and females in each of four Paralympic subgroups: S2–S4, S5–S7, S8–S10 (most through least physically impaired), and S11–S13 (most through least visually impaired). Mixed modelling of log-transformed times, with adjustment for mean competition times, was used to estimate variability and progression. Within-swimmer race-to-race variability, expressed as a coefficient of variation, ranged from 1.2% (male S5–S7) to 3.7% (male S2–S4). Swimming performance progressed by approximately 0.5% per year for males and females. Typical variation in mean performance time between competitions was ~1% after adjustment for the ability of the athletes in each competition, and the Paralympic Games was the fastest competition. Thus, taking into account variability, progression, and level of competition, Paralympic swimmers who want to increase substantially their medal prospects should aim for an annual improvement of at least 1–2%.  相似文献

Abstract

We offer an examination of the processes athletes undertake following a sporting experience in order to learn how to interpret their anxiety-related symptoms as facilitative to performance. Six experienced, elite athletes were interviewed regarding the reflective practices adopted following both positive and negative critical incidents with a view to generating knowledge about their competitive anxiety symptoms. Composite sequence analysis procedures were employed to allow data to be considered as meaningful sequences for both the positive and negative incidents. Findings showed distinctions between the effects of positive and negative incidents on the reflective and learning processes and how this influenced the further appraisal of competitive anxiety symptoms. Support is provided for the use of reflective practice as a framework for experiential learning within sport.  相似文献
