This study explores strategies students use to construct their academic engagement in the social environment of school. The study is based on group interview data collected from 161 sixth (78) and eighth (83) grade students. Students reflected both engaging and disengaging episodes. Data were content analysed. The results show that students reported using only confirming strategies in teacher–student interaction. More diverse strategies were described in relation to peer interaction. The results indicated that simultaneously maintaining functional peer relations and engaging effectively in academic activities is a highly challenging task which requires strategic flexibility and self-regulative skills. In terms of the development of more engaging learning environments for students, our results suggest that more attention should be paid to creating positive opportunities to participate, in terms of both academic activities and peer interaction.  相似文献

The aim of this process-oriented video-observation study is to explore how groups that perform differently differ in terms of the number, quality, and temporal variation of their content-level (knowledge co-construction) and meta-level (monitoring) activities. Five groups of teacher education students (n = 22) were observed throughout a 3-month course. Video recordings (33 hours) of face-to-face group interaction (n = 12,931 speech turns) and pre- and post-tests of students’ knowledge were collected. The results show that the well-performing group was more engaged in high-level knowledge co-construction and monitoring activities. The well-performing group was also capable of maintaining a higher level throughout the tasks, whereas the lower performing groups’ knowledge co-construction and monitoring activities was reduced during the course.  相似文献

OBJECTIVE: The aim of this study was to test a model predicting the contribution of abuse-related characteristics and mediating variables such as coping and attributional style in the development of psychological sequelae in adults reporting a history of child sexual abuse (CSA). METHODOLOGY: Two hundred and eighty-five males and females from three settings (a nonpatient, psychiatric outpatient, and psychiatric inpatient) completed a battery of questionnaires that included a (1) Sexual History Questionnaire, (2) Ways of Coping Questionnaire, (3) Attributional Style Questionnaire, and (4) the SCL-90-R. RESULTS: Of the 285 participants, 33% reported unwanted or forced sexual contact before the age of 18 years. Participants who reported a history of CSA also reported higher levels of psychological distress when compared to those who did not report a history of abuse. In testing the model concerning the relationship between victim-offender characteristics, mediating variables and psychological distress in adulthood; two abuse-related characteristics (number of offenders and duration of abuse) were found to be directly associated with psychological distress in adulthood. Other abuse-related variables (i.e., relation with offender, force, resistance, age of onset, participation, and frequency of abuse) were found to be related to psychological distress in adulthood through the mediation of various coping strategies (i.e., Accepting Responsibility, Confrontive Coping) and attributions (i.e., internalization of the abuse). CONCLUSIONS: The results of the present study further our understanding regarding the relationship between abuse-related characteristics, mediating factors such as coping and attributional style and psychological distress in adults with a history of CSA. Future research should focus on the development of interventions that focus on variables amenable to psychotherapy to ameliorate the psychological sequelae of CSA.  相似文献

The need to preserve cultural heritage on paper requires the setting up of methods and treatments that can be applied to original documents. The cellulose main degradation processes are hydrolysis and oxidation. Only the first one has been widely investigated. The Istituto Centrale per la Patologia del Libro (ICPL) focused its attention on oxidation phenomena and studied a particular class of reducing agents, namely the borane-amine complexes. During the investigation it was found that the borane tert-butylamine complex, besides being the most promising reducing agent, was also able to react with carboxylic functions. In the present study 1H and 13C NMR, Pulsed field gradient NMR spectroscopy as well as Raman spectroscopy were used as analytical tools to disclose the mechanism of the interaction between the borane tert-butylamine complex and the carboxylic functions. Given the complexity of the paper/environment interactions and the subsequent degradation phenomena, we worked on simplified models based on small carbohydrate molecules in order to reproduce the behavior of degraded paper after reductive restoration. Modified D-glucose and D-cellobiose were used in this first step in order to set up the analytical methods before approaching more complex systems such as microcrystalline cellulose and paper. Our results give the experimental evidence that borane tert-butylamine complex is also able to neutralize acidic functions. This finding has important perspectives in paper restoration.  相似文献

This article describes the pedagogical framework of an interdisciplinary and international project entitled NINTER (Networked Interaction: Theory-Based Cases in Teaching and Learning). The practical aim of the project is to produce a pedagogical model for learning and teaching in networked environments. The research project has its foundation on socio-constructivist learning theories, with one of the most important principles being the idea of apprenticeship in thinking. The article also takes a look at the first results obtained from different kinds of videotaped and written material that were collected during a WWW-based university course. Also questions raised from the data for future research are considered.  相似文献

Self-regulated learning (SRL) research has conventionally relied on measures, which treat SRL as an aptitude. To study self-regulation and motivation in learning contexts as an ongoing adaptive process, situation-specific methods are needed in addition to static measures. This article presents an ‘Adaptive Instrument for Regulation of Emotions’ aimed at accessing students’ experiences of individual and socially shared regulation of emotions in a socially challenging learning situation. The instrument, grounded in self-regulated and socially regulated learning theory, comprises four interrelated components: the socio-emotional challenges experienced in a collaborative learning situation; individual and group-level attempts to regulate the immediate emotions evoked by the challenges; the personal goals; and goal attainment pursued in that situation. The theoretical foundation of the instrument and its components are outlined and some reliability issues illustrated. The limitations but also educational potential of the instrument to understand regulation of emotions in socially challenging learning situations are discussed.  相似文献

Little is known about the predictors of adherence in a dance context. The aim of this study was to investigate adherence to a dance talent programme using a multidisciplinary set of variables representing psychological correlates of adherence, maturation and physical factors relating to dance talent. Psychological (passion, motivational climate perceptions, eating attitudes), physical competence (vertical jump height, handgrip strength, hamstring flexibility, external hip rotation, aerobic fitness), and maturation-related (age of menarche) variables were gathered from female students enrolled on a dance talent programme. Participation behaviour (adherence/dropout) was collected from the talent programme’s records approximately two years later. Logistic regression analysis of 287 participants revealed that greater levels of harmonious passion predicted greater likelihood of adherence to the programme, and greater ego-involving motivational climate perceptions predicted less likelihood of adherence. Neither measures of physical competence nor maturation distinguished adhering from dropout participants. Overall, the results of this study indicate that psychological factors are more important than physical competence and maturation in the participation behaviour of young talented dancers.  相似文献

Empirical research reveals that students face difficulties engaging in learning and achieving their goals in a variety of learning contexts. To study effectively, students need to regulate their learning process. In spite of increased understanding of cognitive aspects of self-regulation, motivational aspects of regulation have not yet been thoroughly probed. This study investigates how motivation is connected to self-regulated learning when elementary school students (N = 32) study science in real classroom contexts using gStudy software. This was done by: (1) identifying students' situated motivation during the learning process, (2) analyzing how the students with different motivational approaches activated cognitive self-regulation in authentic learning situations across multiple learning episodes, and (3) complementing the understanding with the students' individual accounts of their motivation regulation during the learning process. The results show that there are qualitative differences in the self-regulation tactics used by the high- and low-motivation students as they study. Motivation is linked closely to active self-regulation.  相似文献

This study examined the role of motivational or attitudinal factors, such as achievement beliefs and behaviours, in learning to read before receiving formal instruction. A total of 200 Finnish children were examined at ages 5 and 6½. Half of them (n = 107) had a familial risk for dyslexia. The results showed that those children who were verbally skilful at age 5 showed a higher level of task-focused behaviour at age 6½. This task-focused behaviour then contributed to spontaneous reading acquisition. The impact of previous verbal skills on spontaneous reading acquisition was mediated in part by achievement behaviour.  相似文献
