This meta-analysis integrates 296 effect sizes reported in eye-tracking research on expertise differences in the comprehension of visualizations. Three theories were evaluated: Ericsson and Kintsch’s (Psychol Rev 102:211–245, 1995) theory of long-term working memory, Haider and Frensch’s (J Exp Psychol Learn Mem Cognit 25:172–190, 1999) information-reduction hypothesis, and the holistic model of image perception of Kundel et al. (Radiology 242:396–402, 2007). Eye movement and performance data were cumulated from 819 experts, 187 intermediates, and 893 novices. In support of the evaluated theories, experts, when compared with non-experts, had shorter fixation durations, more fixations on task-relevant areas, and fewer fixations on task-redundant areas; experts also had longer saccades and shorter times to first fixate relevant information, owing to superiority in parafoveal processing and selective attention allocation. Eye movements, reaction time, and performance accuracy were moderated by characteristics of visualization (dynamics, realism, dimensionality, modality, and text annotation), task (complexity, time-on-task, and task control), and domain (sports, medicine, transportation, other). These findings are discussed in terms of their implications for theories of visual expertise in professional domains and their significance for the design of learning environments.  相似文献

Although a large number of different organisations offer various forest education programmes within Germany, specific information (i.e., sectoral and programme content and provision at a state level) is lacking. This study used a survey of all 61 forest education organisations (43 respondents) in the state of North Rhine‐Westphalia, Germany, to evaluate its forest education sector, with a specific focus on the organisations, demand for its services, forest educational programmes and framework conditions. Input from expert interviews was also used to develop recommendations. The study indicates that, especially with children as the main target group, many non‐formal programmes are offered to support the formal environmental education sector and to promote leisure activities in the forest. Yet, despite a high demand for forest education, low personnel resources restrict the number of visits and activities, principally owing to limited financial resource. We also discuss the provision of innovative new educational programmes and supplementary services, combined with increased quality management, that could be beneficial to the future development of the sector in NRW.  相似文献

Applicant pools for principal vacancies are shrinking nationwide. This shortage of job applicants requires school districts to evaluate their internal pools of principal certified personnel. In this study, 194 certified individuals from a large school district responded to a survey measuring attraction to the job of principal, current job satisfaction versus expected satisfaction in the job of principal, barriers to pursuing the job, and recommended changes in the job. Few participants intended to apply for principal vacancies due to age (median=51), lack of self-reported capability to do the job, and satisfaction with the current job. Participants perceived their job satisfaction would decrease on assuming the job of principal relative to factors such as time with family and job security, and increase relative to factors such as salary and opportunity to experience varied activities. Implications for principal recruitment and recommendations for restructuring the job are discussed.  相似文献

A peer tutored Paired Reading (PR) project was organised involving 10 and 11 year old pupils at two primary schools. Outcome was assessed by reading age. Tutor and tutee behaviour during PR was analysed by sessional tape recordings. The study indicates that many of the tutors involved in this project failed to follow PR procedures closely, that all tutors employed reinforcement at very low rates, that many important errors were left uncorrected, and that tutors were consistent in their adherence to (or neglect of) the procedures in which they had been trained.

There appeared to be no influence of tutees’ initial reading age on either tutee or tutor behaviour during PR sessions. No aspect of either tutee or tutor behaviour during PR was associated with size of reading gain.

Mechanisms underlying the apparent effectiveness of PR (and a number of other tutoring techniques for oral reading) are discussed in the context of the apparent absence of any relationship between tutor adherence to PR and tutee reading gains.  相似文献

Abstract

University rankings are increasingly important internationally, and in the UK include a sustainability ‘Green League’. However, there is little evidence about experiences of studying in ‘sustainable universities’. We report an empirical study at five universities in varied positions in the Green League, exploring students’ energy literacy, environmental attitudes and perceptions of their institution’s energy-saving efforts. Although the link to energy literacy is not clear, findings suggest that there are significant differences between students’ environmental attitudes at universities placed at different points in the league. In addition, students at higher ranked universities are more positive about their university’s energy-saving efforts, suggesting that these institutions may exhibit more overt manifestations of sustainability. This is important since students report being more likely to choose energy-conservation behaviours if there is visible representation of energy use. The study is the first to attempt a comparison between universities at different positions in a sustainability ranking.  相似文献

Es gibt einige Hinweise darauf, dass Vorstellungen vom Lehren und Lernen sowohl für das Handeln der Lehrkr?fte im Unterricht als auch für Zielkriterien auf der Ebene der Schüler eine Rolle spielen. Dabei gelten konstruktivistisch orientierte Sichtweisen als besonders günstig. Empirische Untersuchungen dazu gibt es jedoch bislang nur auf einzelne fachdidaktische Inhaltsbereiche bezogen. In der vorliegenden Studie werden konstruktivistisch orientierte Lehrereinstellungen mit Merkmalen des Unterrichts (?ffnung des Unterrichts im Hinblick auf Entscheidungsm?glichkeiten für Schüler/-innen und Strukturierung des Unterrichts) sowie mit Einsch?tzungen der Schüler/-innen (Selbstbestimmungsempfinden und Interessantheit des Unterrichts) in Beziehung gesetzt. Die Ergebnisse best?tigen die Theorie: In den Klassen der Lehrer/-innen mit überwiegend konstruktivistischen Vorstellungen von Lernen und Lehren gibt es mehr Freir?ume, ohne dass der Unterricht weniger strukturiert abl?uft. Zudem empfinden sich die Schüler/-innen als selbstbestimmter und sch?tzen den Unterricht als interes-santer ein.  相似文献

For this study, information on Who Bullies Who was collected from 54 school classes with 918 children (M age = 11) and 13,606 dyadic relations. Bullying and victimization were viewed separately from the point of view of the bully and the victim. The two perspectives were highly complementary. The probability of a bully-victim relationship was higher if the bully was more dominant than the victim, and if the victim was more vulnerable than the bully and more rejected by the class. In a bully-victim dyad, boys were more often the bullies. There was no finding of sex effect for victimization. Liking reduced and disliking increased the probability of a bully-victim relationship.  相似文献

Effects of joint attention were addressed on 3- to 4-year-olds’ performance in a verbal false-Belief Test (FBT), featuring the experimenter as co-watcher rather than narrator. In two experiments, children (N = 183) watched a filmed-FBT jointly with a test leader, disjointed from a test leader, or alone. Children attending jointly with a test leader were more likely to pass the FBT compared with normative data and to spontaneously recall information indicating false-belief understanding, suggesting that joint attention strengthens the plausibility of the FBT and renders plot-critical information more salient. In a third experiment (N = 59), results were replicated using a typical, image-based FBT. Overall findings highlight the profound impact of experimenter as social context in verbal FBTs, and link recall of specific story features to false-belief understanding.  相似文献
