Despite mixed results in research on student learning from drawing in science, there is growing interest in the potential for this visual mode, in tandem with other modes, to enact and enable student reasoning in this subject. Building on current research in this field, and using a micro-ethnographic approach informed by socio-semiotic perspectives, we aimed to identify how and why student drawing can contribute to student reasoning and learning. In our study, secondary school students were challenged to explore and collaboratively create explanatory representations of phenomena including through drawing. Data were generated using multiple wall- and ceiling-mounted cameras capable of continuously tracking groups of students negotiating these representational challenges. Our analysis proceeded through active and iterative viewing of the extensive video record, and the identification of themes to establish possible relationships between drawing and reasoning. Through this process, we (a) identify multiple necessary conditions and varied opportunities for student drawing to enact and enable reasoning, and (b) extend current understandings of how the particular affordances of this mode interact with these conditions to contribute to student learning in science. 相似文献

In this research, commissioned by the New Zealand Teachers Council, the quality of induction of provisionally registered teachers (PRT) (newly qualified) was examined utilising qualitative ‘success case studies’ within early childhood, primary, secondary, and indigenous Māori medium settings. The establishment of criteria for effective induction (from the literature and previous research) guided the identification of 20 ‘success’ sites across the sectors. In-depth data collection of each case was conducted via focus groups, one-to-one interviews and documentary analysis. The findings of the research highlighted exemplary induction practices across the sectors, with the most important associated with PRTs having access to a community, or ‘family’, of support during their induction. An interesting finding, which contrasted with previous research, was that PRTs in the secondary sector had levels of satisfaction with their role that were as high as those in other sectors. The key limitation to effectiveness was linked to lack of time for discussions and observations of the PRT's practice. 相似文献

In an experiment with 109 undergraduates, we examined the effect of mood, cognitive style, and cognitive ability on implicit learning in the Artificial Grammar (AG) and Serial Reaction Time (SRT) tasks. Negative mood facilitated AG learning, but had no significant effect on SRT learning. Rational cognitive style predicted greater learning on both tasks, but this effect on SRT was mediated by cognitive ability. SRT, but not AG learning was significantly correlated with Math and English scores on the ACT. These findings confirm and contradict previous research. The association of negative mood and rational cognitive style with AG confirms that AG learning is facilitated by systematic, bottom-up processing. However, the lack of converging evidence for the SRT task suggests that the tasks involve different aspects of implicit processing. Theoretical explanations and suggestions for future research are discussed. 相似文献

Some argue that the goal of education is to influence out‐of‐school learning activity, yet little research exists on how teachers can help students develop an interest in a topic and continue to pursue that interest outside of school. The current study tested classroom context variables from self‐determination theory (teachers’ autonomy support) and from achievement goal theory (teachers’ mastery goals) that may predict students’ school‐prompted interest above and beyond students’ mastery goals and self‐efficacy. Survey data were collected from 178 high school students in 15 mathematics classes. Hierarchical multiple regression revealed that students’ perceptions of a teacher who focuses on mastery goals account for little variance above and beyond students’ own motivation, whereas perceived teachers’ autonomy support emerged as a significant predictor. While the results are correlational and do not support causal claims, they suggest that teachers who support student autonomy might foster school‐prompted interest. 相似文献

This paper describes an innovative way of randomly collecting handwritten homework in calculus classes with approximately 50 students using a standard deck of cards, which does not place an excessive burden on faculty with regard to grading. In addition to the increased awareness students develop in structuring a mathematical solution, the strategy has been successful in increasing classroom attendance, which the literature suggests leads to increased attainment. Along with personal observations and empirical data indicating that the scores from the randomly collected homework assignments strongly correlate with exam performance, perceptions of students are included, which show that students are strongly supportive of the method used. 相似文献

AbstractThe aim of the current study was to investigate the validity and reliability of a radio frequency-based system for accurately tracking athlete movement within wheelchair court sports. Four wheelchair-specific tests were devised to assess the system during (i) static measurements; (ii) incremental fixed speeds; (iii) peak speeds; and (iv) multidirectional movements. During each test, three sampling frequencies (4, 8 and 16 Hz) were compared to a criterion method for distance, mean and peak speeds. Absolute static error remained between 0.19 and 0.32 m across the session. Distance values (test (ii)) showed greatest relative error in 4 Hz tags (1.3%), with significantly lower errors seen in higher frequency tags (<1.0%). Relative peak speed errors of <2.0% (test (iii)) were revealed across all sampling frequencies in relation to the criterion (4.00 ± 0.09 m · sˉ1). Results showed 8 and 16 Hz sampling frequencies displayed the closest-to-criterion values, whilst intra-tag reliability never exceeded 2.0% coefficient of variation (% CV) during peak speed detection. Minimal relative distance errors (<0.2%) were also seen across sampling frequencies (test (iv)). To conclude, the indoor tracking system is deemed an acceptable tool for tracking wheelchair court match play using a tag frequency of 8 or 16 Hz. 相似文献

We used data from the American Time Use Survey (years 2003–06) to analyze whether the intensity and duration of high school students' (ages 15–18 years) sports and exercise bouts differed across physical and social environments. Boys' sports and exercise bouts were more likely to reach a vigorous intensity when taking place at school and with friends/acquaintances/other people; whereas girls' sports and exercise bouts were more likely to reach a vigorous intensity when outdoors and alone. For boys and girls, bout durations were greater at school and with friends/acquaintances/other people than in other environments. Overall, environmental influences on the intensity but not duration of sports and exercise bouts appear to differ between boys and girls. 相似文献

AbstractThe purpose of the study was to determine which laboratory-based modality provides the most valid physiological and biomechanical representation of over-ground sports wheelchair propulsion. Fifteen able-bodied participants with previous experience of wheelchair propulsion performed a 3-minute exercise trial at three speeds (4, 6 and 8 km ? h–1) in three testing modalities over separate sessions: (i) over-ground propulsion on a wooden sprung surface; (ii) wheelchair ergometer propulsion; (iii) treadmill propulsion at four different gradients (0%, 0.7%, 1.0% and 1,3%). A 0.7% treadmill gradient was shown to best reflect the oxygen uptake (7.3 to 9.1% coefficient of variation (CV)) and heart rate responses (4.9 to 6.4% CV) of over-ground propulsion at 4 and 6 km ? h–1. A 1.0% treadmill gradient provided a more valid representation of oxygen uptake during over-ground propulsion at 8 km ? h–1 (8.6% CV). Physiological demand was significantly underestimated in the 0% gradient and overestimated in the 1.3% gradient and wheelchair ergometer trials compared to over-ground trials (P<0.05). No laboratory-based modality provided a valid representation of the forces applied during OG (≥ 18.4% CV). To conclude, a 0.7% treadmill gradient is recommended to replicate over-ground wheelchair propulsion at lower speeds (4 and 6 km ? h–1) whereas a 1.0% gradient may be more suitable at 8 km ? h–1. 相似文献
