Classroom experience is shaped by a number of factors. In this paper, we report a classroom observation study in China, illustrating regional variation in students' classroom learning experiences. Through comparing and contrasting observed classroom practices in three different regions in China (Chongqing, Hong Kong and Shanghai), the paper provides an analysis of the variation in classroom learning experiences of primary school students in China. Our empirical classroom observation data illustrates some key differences in the pedagogy, the use of classroom activities, and the implementation of the curriculum between individual schools. More substantial differences in classroom practices are found when comparing schools from different regions than those within a given city, leading us to conclude that regional impacts on student experience appear to be more important than within-city factors such as the location of a school or its level of facilities.  相似文献

The aim of the present study was to examine the involvement, beliefs, and knowledge of social workers in health care settings in the process of making decisions regarding life-sustaining treatments. A convenience sample of 68 social workers participated in the study (65 F and 3 M; mean age = 42.4 ; SD = 10.0 . Fifty-two participants worked at hospitals and 16 at nursing homes. The area in which social workers reported being more involved were activities related to family members. The extent of social workers' involvement was related to their beliefs regarding their role and their knowledge about life-sustaining treatments. Findings of this study emphasize the need for developing educational programs aimed at expanding social workers' knowledge in order to increase their autonomy and professional involvement in end-of-life decision making.  相似文献

Using plain white and chequered footballs, we evaluated observers’ sensitivity to rotation direction and the effects of ball texture on interceptive behaviour. Experiment 1 demonstrated that the maximal distance at which observers (= 8) could perceive the direction of ball rotation decreased when rotation frequency increased from 5 to 11 Hz. Detection threshold distances were nevertheless always larger for the chequered (decreasing from 47 to 28 m) than for the white (decreasing from 15 to 11 m) ball. In Experiment 2, participants (n = 7) moved laterally along a goal line to intercept the two balls launched with or without ±4.3 Hz sidespin from a 30-m distance. The chequered ball gave rise to shorter movement initiation times when trajectories curved outward (±6 m arrival positions) or did not curve (±2 m arrival positions). Inward curving trajectories, arriving at the same ±2 m distances from the participants as the non-curving trajectories, evoked initial movements in the wrong direction for both ball types, but the amplitude and duration of these reversal movements were attenuated for the chequered ball. We conclude that the early detection of rotation permitted by the chequered ball allowed modulation of interception behaviour without changing its qualitative characteristics.  相似文献

Despite the substantial amount of work which has been conducted into teachers’ research engagement in mainstream education, this topic has been awarded scant attention in the field of English language teaching. This paper presents the results of a survey representing the first stage of multi-method investigation of research engagement in ELT. Moderate levels of reading and doing research were reported by the sample studied here, and this level of research engagement is analysed in relation to two key factors also examined in the survey: teacher's conceptions of research and their perceptions of the institutional research culture.  相似文献

Media education forms part of the National Minimum Curriculum of England, Malta and Germany. Teacher training courses differ greatly in how teachers are prepared to teach media education. In this paper we shall investigate the attitudes of a sample of teachers trained in England, Malta and in Germany towards their perceived importance of media education and the teachers' preparedness to teach the subject. This preliminary study had a sample of 132 participants, 33 teachers from England, 47 from Germany and 52 teachers from Malta. The tool used to collect data was an online questionnaire. The results show that teachers taking part in this study were not given enough training, or any training at all to be able to teach media education with the result that they do not feel sufficiently prepared to teach the subject. It is suggested by the authors that media education becomes a compulsory component of the initial teacher training courses as well as advanced training for teachers.  相似文献

Limited information exists about the movement patterns of field-hockey players, especially during elite competition. Time-motion analysis was used to document the movement patterns during an international field-hockey game. In addition, the movement patterns of repeated-sprint activity were investigated, as repeated-sprint ability is considered to be an important fitness component of team-sport performance. Fourteen members of the Australian men's field-hockey team (age 26+/-3 years, body mass 76.7+/-5.6 kg, VO2max 57.9+/-3.6 ml.kg(-1).min(-1); mean+/-s) were filmed during an international game and their movement patterns were analysed. The majority of the total player game time was spent in the low-intensity motions of walking, jogging and standing (46.5+/-8.1, 40.5+/-7.0 and 7.4+/-0.9%, respectively). In comparison, the proportions of time spent in striding and sprinting were 4.1+/-1.1 and 1.5+/-0.6%, respectively. Our criteria for 'repeated-sprint' activity (defined as a minimum of three sprints, with mean recovery duration between sprints of less than 21 s) was met on 17 occasions during the game (total for all players), with a mean 4+/-1 sprints per bout. On average, 95% of the recovery during the repeated-sprint bouts was of an active nature. In summary, the results suggest that the motion activities of an elite field-hockey competition are similar to those of elite soccer, rugby and Australian Rules football. In addition, the investigation of repeated-sprint activity during competition has provided additional information about the unique physiological demands of elite field-hockey performance.  相似文献
