Newborn infants orient preferentially toward face‐like or “protoface” stimuli and recent studies suggest similar reflexive orienting responses in adults. Little is known, however, about the operation of this mechanism in childhood. An attentional‐cueing procedure was therefore developed to investigate protoface orienting in early childhood. Consistent with the extant literature, 5‐ to 6‐year‐old children (n = 25) exhibited orienting toward face‐like stimuli; they responded faster when target location was cued by the appearance of a protoface stimulus than when location was cued by matched control patterns. The potential of this procedure to investigate the development of typical and atypical social perception is discussed. 相似文献

Effective feedback can build self-assessment skills in students so that they become more competent and confident to identify and self-correct weaknesses in their work. In this study, we trialled a feedback code as part of an integrated programme of formative and summative assessment tasks, which provided feedback to first-year students on their initial attempt at a scientific biology report. We investigated the students’ perceptions of the feedback code and associated action plan exercise, and found that the code provided the majority of students with clear feedback, whilst the action plan provided a tool for decoding and interpreting the feedback and ensuring errors were not repeated in a subsequent report. We argue that a feedback code can be a valuable inclusion in a wider programme of feedback provision particularly when it is supported by activities that require students to engage with the codes and feed that learning forward to subsequent tasks. 相似文献

It has been established by previous researchers that changes in the wording of multiple‐choice examination questions can significantly affect pupil performance. In this study recent ‘home’ General Certificate of Secondary Education (GCSE) and ‘overseas’ General Certificate of Education (GCE) papers were examined for questions in which the language could be simplified, and modified questions were prepared. When performance on the original and modified forms of the questions was compared for a sample of British school pupils, no statistically significant difference emerged. When performance on the same questions was examined for a sample of pupils for whom English was the second (or third) language, there were significant differences in their performance on modified and unmodified versions of the questions. 相似文献

The Developing Understanding of Assessment for Learning (DUAL) programme was developed with the dual aims of improving both the quality and consistency of feedback students receive and the students’ ability to use that feedback to improve. DUAL comprises a range of processes (including marking rubrics, sample reports, moderation discussions and peer-review activities) which support explicit knowledge exchange between staff, and between staff and students and the development of tacit knowledge of standards in all participants. This paper describes the study which quantified the extent to which the DUAL programme improved reliability and efficiency of marking of first year biology reports by a large team of laboratory demonstrators. Marker reliability increased after participation in DUAL, with demonstrators marking laboratory reports significantly closer to the marks awarded by an expert marker of the discipline. Efficiency was also improved since time taken to mark the reports did not increase significantly, despite the fact that demonstrators were adapting to a new system of marking. Demonstrators valued the programme and nominated the marking rubric, feedback code and moderation discussion as the most useful elements. The community of practice built through joint participation in the DUAL programme created a supportive working environment for demonstrators and strengthened the collaboration between the discipline and academic language and learning lecturers. 相似文献

In this study, we assessed the agreement between the powers recorded during a 30?s upper-body Wingate test using three different methods. Fifty-six men completed a single test on a Monark 814E mechanically braked ergometer fitted with a Schoberer Rad Messtechnik (SRM) powermeter. A commercial software package (Wingate test kit version 2.21, Cranlea, UK) was used to calculate conventional and corrected (with accelerative forces) values of power based on a resistive load (5% body mass) and flywheel velocity. The SRM calculated powers based on torque (measured at the crank arm) and crank rate. Values for peak 1 and 5?s power and mean 30?s power were measured. No significant differences (P?>0.05) were found between the three methods for 30?s power values. However, the corrected values for peak 1 and 5?s power were 36 and 23% higher (P?<0.05) respectively than those for the conventional method, and 27 and 16% higher (P?<0.05) respectively than those for the SRM method. The conventional and SRM values for peak 1 and 5?s power were similar (P?>0.05). Power values recorded using each method were influenced by sample time (P?<0.05). Our results suggest that these three measures of power are similar when sampled over 30?s, but discrepancies occur when the sample time is reduced to either 1 or 5?s. 相似文献

The aim of this study was to assess the effects of the age and sex of the competitor on orienteering speed during competitive events. The results of the fastest three male and fastest three female competitors in each 5-year age band (21-79 years), from four national orienteering events, were analysed. The data for age and orienteering speed were log-transformed and regression analyses were conducted to determine the relationships between age and sex and orienteering speed. For comparison, data for the fastest Great Britain finisher in the 10,000-m track and 10-km cross-country events for age groups 40-69 years at the World Masters Championships were also analysed. The results showed that, before the age of 40 years, there was no substantial slowing in orienteering speed for males (0.5-4.2% per decade) but a moderate decline (4.7-10.0% per decade) for females. After the age of 45 years, the orienteering speed of males and females slowed by 13+/-2% and 16+/-4% per decade (mean +/- s), respectively, until around the age of 69, after which the deterioration was accentuated. The orienteering speed of the females was 81+/-4, 74+/-6 and 69+/-7% that of the males at ages 21, 45 and 65 years, respectively. The magnitudes of the age-related slowing of orienteering speed and of the difference in orienteering speed between males and females aged 45 years and over were greater than those reported for the other endurance running events. This may reflect the physical demands of running in orienteering terrain, tactical and cognitive aspects of the sport, or sociocultural aspects of the participating population. 相似文献
