This article reports on analyses of the instructional practices of six middle- and high-school science teachers in the United States who participated in a research-practice partnership that aims to support reform science education goals at scale. All six teachers were well qualified, experienced, and locally successful—respected by students, parents, colleagues, and administrators—but they differed in their success in supporting students' three-dimensional learning. Our goal is to understand how the teachers' instructional practices contributed to their similarities in achieving local success and to differences in enabling students' learning, and to consider the implications of these findings for research-practice partnerships. Data sources included classroom videos supplemented by interviews with teachers and focus students and examples of student work. We also compared students' learning gains by teacher using pre–post assessments that elicited three-dimensional performances. Analyses of classroom videos showed how all six teachers achieved local success—they led effectively managed classrooms, covered the curriculum by teaching almost all unit activities, and assessed students' work in fair and efficient ways. There were important differences, however, in how teachers engaged students in science practices. Teachers in classrooms where students achieved lower learning gains followed a pattern of practice we describe as activity-based teaching, in which students completed investigations and hands-on activities with few opportunities for sensemaking discussions or three-dimensional science performances. Teachers whose students achieved higher learning gains combined the social stability characteristic of local classroom success with more demanding instructional practices associated with scientific sensemaking and cognitive apprenticeship. We conclude with a discussion of implications for research-practice partnerships, highlighting how partnerships need to support all teachers in achieving both local and standards-based success.  相似文献

李贺、李商隐“登仙”诗歌中的通感表现手法析论     

魏刚  龙科廷 《六盘水师范高等专科学校学报》2014,(3):15-20

从诗歌理论角度而言,通感是一种诗歌表现手法。唐代李贺与李商隐的"登仙"类诗歌,运用通感手法为"登仙"主题服务,可以引用通感理论来分析其具体艺术特色。另外,二李最大的不同在于是否愿意融入宗教核心。李贺宁可以艺术通感技法来"创造"一个生动活脱的仙境,也不愿深入宗教核心,这是他与义山最大的不同。而"登仙"对李贺而言是一种摹幻及创造性的审美活动,对义山而则为力图实践的宗教活动。  相似文献   

Parenting styles and bullying. The mediating role of parental psychological aggression and physical punishment     

《Child abuse & neglect》2016

Studies concerning parenting styles and disciplinary practices have shown a relationship between both factors and bullying involvement in adolescence. The scarce available evidence suggests that abusive disciplinary practices increase teenagers’ vulnerability to abuse in school or the likelihood of them becoming abusers of their peers in the same context. However, there is a lack of knowledge about the indirect effect of parenting styles in adolescents’ bullying involvement through disciplinary practices, although a relationship between parenting styles and disciplinary practices has been shown. The aim of this research was to determine the mediating role of punitive parental discipline (physical punishment and psychological aggression) between the dimensions of parents’ parenting styles and their children's involvement in bullying victimization and aggression. We used a sample comprising 2060 Spanish high school students (47.9% girls; mean age = 14.34). Structural equation modeling was performed to analyze the data. The results confirmed the mediating role of parental discipline between the parenting practices analyzed and students’ aggression and victimization. Significant gender-related differences were found for aggression involvement, where boys were for the most part linked to psychological aggression disciplinary practices and girls to physical punishment. Victimization directly correlated with parental psychological aggression discipline behavior across both sexes. In conclusion, the results seem to suggest that non-democratic parenting styles favor the use of punitive discipline, which increases the risk of adolescents’ bullying involvement. Therefore, intervention programs must involve parents to make them aware about the important role they play in this process and to improve their parenting styles.  相似文献

Teen Perceptions of the Promotion of Safer Sexual Practices: A Focus Group Study     

Judith W. Herrman  Andrea Kelley  Katherine M. Haigh 《American journal of sexuality education》2017,12(1):83-102

Teens' own thoughts on fostering safe sexual practice are important perspectives in promoting adolescent sexual health yet are relatively absent in the literature. This focus group study explored teens' perceptions about the supports and challenges that exist as teens strive to engage in healthy sexual practices. Seventy-five teens participated in 11 focus groups using a semi-structured interview guide. School-based health centers provided the setting and facilitated sample recruitment. Focus groups were audiorecorded and transcribed verbatim. Data were analyzed using the focus group guide as a template and typologies, or clusters of concepts, were extracted to establish teen perceptions of the factors that support and challenge their ability to engage in safe sexual practices. The socio-ecological model provided the framework to identify these factors within the individual, family/parent, relational (peer/partner), community, or societal spheres of influence. Results discussed the importance of parents, the value of confidentiality, respect for teen decision-making, relationships skills, developmental aspects of the adolescent years, and social interpretations of gender. These findings revealed important considerations as adults develop policies, messages, and programs designed to promote safe sexual behavior in teens.  相似文献

Collaborative working in a large pharmaceutical company: Developing better practices through a structurational schema     

James  Laurence 《International Journal of Information Management》2005,25(6):551-564

This paper presents the ongoing case study of a large pharmaceutical organisation currently undertaking a number of changes to their work practices. These collaborative changes are being facilitated by groupware systems. In many instances this has led to the rejection of or resistance to the more complex tools. The paper outlines research, based on a perspective informed by structuration theory, that provides the organisation with an approach to supporting staff in this new ‘collaborative environment’. An example, drawn from the case study, shows how such support might be developed and presents a set of recommendations for supporting a particular group, based on this research schema.  相似文献   

Transition to formal schooling: Do transition practices matter for academic performance?     

Annarilla Ahtola  Gintautas SilinskasPirjo-Liisa Poikonen  Marita KontoniemiPekka Niemi  Jari-Erik Nurmi 《Early childhood research quarterly》2011,26(3):295

This study examined whether the transition practices implemented in preschool-elementary school pairs contribute to children's academic development during the first year of elementary school. Participants were 398 children who moved from 36 preschools to 22 elementary schools in two Finnish towns. Children were tested in respect to their reading, writing, and math skills in the preschool spring and in the grade 1 spring. The most common practices reported by preschool teachers were discussions about the school entrants and familiarizing preschool children with the school environment and the new teacher. Multilevel latent growth modeling showed that the more the preschool teachers and elementary-school teachers implemented various supportive activities during the preschool year, the faster the children's skills developed from preschool to grade 1 spring. Co-operation over curricula and passing on written information about children between the preschool and the elementary school were the best predictors of the children's skills, although they were the least commonly used practices. The need to restructure the transition to elementary school and the use of multiprofessional resources are discussed.  相似文献
