Peter Senge's (1990) theory of organizational change includes teams that perceive the whole of the organization; grow professionally; navigate short- and long-term organizational experiences through exposed mental models; share a vision; and hear each voice in an ongoing communal learning process. The Margaret Sue Copenhaver Institute for Teaching and Learning is changing teacher education and professional development by employing Senge's model of learning organizations.

When you ask people what it is like being part of a great team, what is most striking is the meaningfulness of the experience. People talk about being part of something larger than themselves, of being connected, of being generative. It becomes quite clear that, for many, their experiences as part of truly great teams stand out as singular periods of life lived to the fullest. Some spend the rest of their lives looking for ways to recapture that spirit. (Senge 1990, 13)  相似文献

Adolescent girls reported on their experiences both as perpetrators and as victims of several distinct forms of relational aggression. Details of these incidents were gathered from 114 ethnically diverse ninth and tenth graders via a secure online survey. The frequency with which girls perpetrated or were targeted for particular acts of relational aggression was assessed and, based on the responses, a computer program randomly selected one item (i.e., gossip, ignoring, or exclusion) for which each girl was asked to recall a specific experience and answer follow‐up questions. Perceptions of the goals and functions of specific relationally aggressive acts were assessed, as well as how the perpetrator or victim felt at the time of the incident. Ignoring or “giving the silent treatment” appeared to be a unique form of relational aggression inasmuch as the girls perceived different motives, or functions, for ignoring compared with gossip and exclusion and felt worse at the time of the ignoring incident, both when they were reporting as aggressors and as victims. © 2010 Wiley Periodicals, Inc.  相似文献

Bicycle riding is a functional motor skill that increases physical activity opportunities, social interaction, and independence. However, bicycle riding is difficult for youth with autism spectrum disorder (ASD) to learn. This study examined the effectiveness of home-support consultation (HSC) on increasing the maintenance of independent bicycle riding following initial skill acquisition. Fifty-one youth with a confirmed ASD diagnosis learned to ride a two-wheeled bicycle during a training camp. Twenty-nine riders enrolled in a HSC intervention to promote distributed practice of the learned skill. The control cohort (N = 22) was exempt from the HSC intervention. One year following initial skill acquisition, 62.07% of the HSC cohort compared to 36.36% of the control cohort still reportedly displayed the skill. Within the HSC cohort, riders who reported at least 8 weeks of practice following acquisition on average maintained the skill. Implications of home consultation are discussed.  相似文献

Teacher education programs attempt to prepare preservice teachers for the various challenges faced in the classroom. One particular challenge new teachers face is how to handle unsuccessful practices. This paper argues that confronting ineffective practices require that teachers respond to complex and dynamic challenges, making change difficult when solutions are not readily available. Presenting data from case-study research, the paper uses an identity framework and positioning theory to explore how two novice teachers navigate moments of unsuccessful practice. Findings suggest that when teachers confronted ineffective practices they repositioned their teacher identities in ways that depended on the ideologies of their school. The paper concludes with implications about the importance of extending typical reflective practices of teacher education with video analysis that challenges students to examine how they enact teacher identities over time within the figured world of their school.  相似文献

This study investigated the effects of student and classroom characteristics on math self-confidence, perceived usefulness, and enjoyment of mathematics as multiple outcomes. A sample of 7th-grade students from 78 classes of 49 schools was studied. The data were collected using, among other instruments, an attitude questionnaire. The results of the multivariate multilevel analysis showed that the variance of the 3 indicators was situated mostly at the student level, and that the indicators correlated strongly at the class level. Higher prior mathematics achievement and positive parental beliefs and attitudes were significant predictors of higher scores across the 3 indicators. Each of the baseline indicators was significantly associated with its corresponding final indicator. At the classroom level, classroom assessment was significantly associated with less endorsement of all 3 indicators, higher levels of classroom modeling with greater endorsement of perceived usefulness of mathematics, and classroom questioning with greater enjoyment of mathematics.  相似文献
