This study focuses on students who change from the academic to the non-academic school track after grade 7 (probationary year) in Berlin. We examined which individual student characteristics (e.?g., performance, school biography, family background) predict school change after the probationary year. We were particularly interested as to whether there are secondary effects of social background, after controlling for differences in performance. Our analyses were based on data from a study which included a whole cohort of school track changers (N?=?754) who were compared with students that remained at the academic track (N?=?1470). In order to predict the change of school type, multivariate logistic regression analyses were performed. Results revealed significant differences between both groups regarding all observed characteristics. Performance-related characteristics were the best predictors of track change. After controlling for these characteristics, no further significant effects for other predictors were observable (i.?e., no secondary effects of social background were present).  相似文献

Recent research on student learning in higher education has increasingly focussed on experiential aspects of how students approach their studies and what they learn from their studies. In this paper we describe the results of a study using phenomenographic research techniques, which focusses on student learning in a first year university physics course. The study, using interviews with sixteen volunteer students from the course, shows that only those students who actively sought to change their conceptions of the subject matter did so, while those who sought only to reproduce that subject matter did not.  相似文献

This paper presents the results of an experimental evaluation of a change in assessment practice in one comprehensive secondary school. The school divided 104 Year 7 pupils into four mixed-ability teaching groups. One of these was given enhanced formative feedback on their work for one year, but no marks or grades. The other three groups were given marks and grades with minimal comments, which was the usual prior practice in this school (and many others). Using data derived from assessment, prior attainment, pupil attitudes and background information, we conducted a contextualized analysis of progress in the four teaching groups for all subjects. This showed that progress in the treatment group (formative feedback only) was substantially inferior to that of the other three groups. In this paper, we also use data from observation of the process and from group interviews with the students involved, to help explain these results. Our findings are relevant to a consideration of the often lessened impact of research findings when 'rolled' out into wider practice, and what may be done about this.  相似文献

This study examined the effects of relaxation training and biofeedback on attention to task and on impulsivity as measured by the Matching Familiar Figures Test (MFFT) among 36 hyperactive male children. Subjects who were identified through teacher ratings on the abbreviated Conners’ Behavior Rating Scale were randomly assigned to treatment and control groups. The experimental treatment consisted of three sessions (each session consisting of 2 phases) of relaxation training and biofeedback. There were no significant differences on all pretest measures (baseline electromyographic readings, pretest error on attention task, and pretest latency). However, differences on all these measures became statistically significant (p < .01) with the treatment group improving attention to task scores and decreasing impulsivity scores. When all pretest data, posttest error, student's age and teacher's rating were controlled for, analysis of covariance results confirmed the significant differences between both groups. It was concluded that relaxation training and biofeedback warrants inclusion in programs designed for hyperactive male children.  相似文献

The onset of regular nonparental care for infants and toddlers has complex psychobiological and behavioral effects on their functioning both at home and in child care centers. Maladaptive behavior on the part of children who spend many hours in child care may reflect not the direct effects of nonparental care but the inability of parents to buffer the enhanced levels of stress experienced in child care. Successful adaptation demands careful equilibration of the contrasting limitations and benefits of the two environments, with parental care characterized by stress reduction and emotional regulation and providers' care characterized by emphasis on cognitive stimulation and behavioral regulation.  相似文献

Few question the importance of effective engagement in computer-supported learning. Yet, comparatively little attention has focused on extrapolating the implications of available research and theory for the design of interaction strategies. Traditionally, interaction strategies have emphasized functions of the interaction, specific strategies for interaction design, and methods for eliciting overt responses. While the functions and operations of design are important, the physical and cognitive aspects of interaction strategies need to be better integrated. In this paper, several perspectives on interaction strategies and computer technology are presented and critically analyzed, dimensions of interaction are examined, and a framework for the design of interaction strategies is presented.  相似文献

This paper presents student perspectives on what they consider to be a fair and equitable national education system, based on their own experiences of primary and secondary level schooling by the age of 13 or 14. A survey of 5432 students in five countries involved a questionnaire administered as part of an EU‐funded project to develop indicators of equity in European school systems. Overall, the UK students reported favouring an egalitarian system where all students were treated in the same way, and this was largely what they felt that they experienced. In this respect, they differed from their peers in the other EU countries, a substantial proportion of whom thought that the least able should receive more support and attention in class, but who found that more attention was actually given to the more able. The UK students also appeared to be more self‐confident about their ability to succeed in school. We discuss these results in terms of policies for school allocation, student assessment and the formation of personal notions of justice. In particular, we argue that equity in structure and procedure is important for the effective teaching of notions of justice in citizenship studies.  相似文献

At 9 or 11 days of age, separate groups of Swiss-Webster mice received 12, 24, or 40 training trials to the goal opposite their first-trial choice in a shock-escape T-maze task. All groups were retested to the same goal for 25 trials 24 h following training, while maturation controls without prior exposure were trained to the goal opposite their first choice. All groups demonstrated increased escape proficiency during original training on two separate escape components: reaching the choice point and making the correct turn at the choice point. During retention testing, all groups at both ages exhibited better escape performance in terms of reaching the choice point than their maturation controls. However, when escape was measured in terms of choice, none of the groups trained at 9 days of age differed significantly from maturation controls when retested at 10 days of age. In contrast, retention of correct choice point turn varied directly with number of original training trials for mice trained at 11 days of age.  相似文献

Two experiments allowed rats to drink freely two neutral flavors (almond and vanilla) in simultaneous compound with two hedonically valued flavors (quinine and saccharin). The neutral flavor previously paired with saccharin was subsequently preferred. The neutral flavor that had been paired with quinine was subsequently avoided. Experiment 3 found similar results when the animals were hand-fed a preset amount of the solution. Preference shifts were not obtained when differential amounts of the neutral flavors were consumed in isolation. The data indicate that flavor-flavor associations can shift taste preferences.  相似文献
