This paper reports on the novel use of classroom videos by 71 pre-service teachers enrolled in a one-year graduate diploma pre-service teacher education program across three Australian universities. The classroom videos were of an experienced teacher delivering a Year-6 mathematics lesson. Students observed, discussed and debated practices that were evident. Data were collected via observation protocols and through recorded focussed discussions. Pre-service teachers, even at the early phase of their course, were able to articulate theoretical explanations for events occurring in the lesson. All students, irrespective of the progression in the course, lamented the absence of prior opportunities to engage in analysis and discussion of classroom lessons. The study reinforces the value of dialectical interactions focussed on authentic teaching scenarios. 相似文献

This study examines how a school’s capacity for institutional diversity relates to student achievement in socio-economically, ethnically, and linguistically diverse schools. It also investigates whether various student groups benefit differently from a school’s level of student diversity and its institutional capacity for diversity. Using data from the High School Longitudinal Study of 2009 (HSLS:09), the study uses two-level hierarchical linear models to explore the relationships between multiple types of school diversity and student achievement and to examine the role played by an institution’s capacity for diversity. Our findings confirm that different types of school diversity have different associations with the academic achievement of students from varied family and language backgrounds. We also find that a school’s capacity for diversity is a significant predictor of the academic success of students, particularly for students from lower income families and those who use a home language other than English. 相似文献

AbstractThis study examines the verbal interactions among a group of pre-service teachers as they engaged in scientific discussions in a medicinal chemistry course. These discussions were part of the course that encompassed an explicit instruction of scientific argumentation structures as well as an applied component, whereby the pre-service teachers learned the content of medicinal chemistry through cases developed using the strategy of competing theories. By adopting a case study approach using sociocultural framework of learning, we examined the interactions between the pre-service teachers using video data. We describe 12 possible forms of interactions during discussions – (1) seeking clarification, (2) figuring out loud, (3) sharing information, (4) agreement, (5) asking questions, (6) providing explanations, (7) raising strategic and procedural issues, (8) stating claims, (9) disagreement, (10) sharing perspectives, (11) offering alternatives, and (12) persuasion. The pre-service teachers engaged in figuring out aloud and seeking clarifications frequently, and used persuasion least in their discussions. To clarify their ideas and thoughts, pre-service teachers commonly rebut their counterparts and used warrants to support their own assertions. A similar pattern was also observed when figuring their thoughts out loud. Our findings suggest that pre-service teachers were able to carry out rebuttals in the argumentation process. However, the quality and function of their rebuttals can be improved by deepening their understanding of the subject matter knowledge and the science argumentation structure. Implications are discussed. 相似文献

Characterization of an Ordinary Teaching Practice with the Help of the Theory of Didactic Situations
In this paper, we use the theory of didactic situations to characterize a mathematics teaching practice, currently used in
secondary schools in France, which we have called interactive synthesis discussion. We have studied this practice in ordinary classes, i.e. classes where the researcher intervenes neither in the preparation
nor in the management of the lessons. We have looked at the didactic situations the teacher chooses, and how he manages his
teaching project, the students’ work in the classroom and at home, and classroom interactions. We present two case studies
of experienced teachers, one in grade 8, and the other in grade 10. 相似文献

AbstractThe crucial role of teacher-student relationships has been reported in many studies. Yet, how teacher-student relationships develop from moment-to-moment interactions during lessons remains understudied. The present study combined insights from interpersonal theory and dynamic systems approaches to study indices of interpersonal content and structure in teacher-student interactions and their association with the teacher’s interpersonal style. We found that moment-to-moment teacher behavior was indeed related to student perceptions of the teacher’s interpersonal style. Indices of variability (structure) in interactions discriminated between teachers with less preferred and more preferred interpersonal styles, while, contrary to earlier research, the indicator of predictableness of interactions could not. Results are discussed considering the expectations, and suggestions made for future research and practice. 相似文献

The conductance and polarization are studied in one-dimensional ballistic quantum wire with both Rashba and Dresselhaus spin-orbit interactions.Two kinds of structures are considered in the present work,one with mixture of two interactions and the other with sequence structure of them.We find that the conductance and polarization are strongly affected by these two interactions.With both interactions we obtain a multi-peak contour of spin polarization and a dramatic oscillation pattern of spin conductance,which are due to the different combination of the two spin-orbit interactions. 相似文献

The aim of this paper is to propose an explanation of the changes of dynamic matching between systemic properties of local production systems (LPS) and characteristics of the competitive environment. An evolutionary sequence travelled during the last three decades by Italian LPS is identified and an explanation of long-term dynamics is based on how information flows and knowledge are structured within a local environment. The “traditional” pattern of interlocking behaviours of different agents is defined as cognitive architecture, which evolutionarily emerges as invisible mind. Evolutionary pressures lead new patterns of relationships and interlocking behaviours, which we define as a tendency for more visible “minds” to assert themselves. 相似文献

Teacher interactions are seen as a source for teachers’ professional development. To better understand this potential, research is needed into who is consulted in data use. Therefore, this study investigates whether Flemish teachers’ popularity in data use discussions can be attributed to formal aspects of the formal school organization, similarity among teachers, proximity and informal bonds between teachers. A multi method study combining social network analysis and interview data was designed. The results reveal that informal bonds between teachers may not be overlooked in how interactions are formed. Because the participants do not seem to choose the colleagues they interact with for data use purposefully, the potential of these interactions for their professional development is questionable. Future research should invest in examining how conscious teachers are of the knowledge and skills of their colleagues in data use and how this knowledge affects the formation of data use interactions. 相似文献

Teachers are often viewed as being primarily responsible for the quality of their classroom environment and teaching practices. Yet, the aggregate skills and competencies of children within classrooms may affect teachers’ ability to engage in emotionally and instructionally supportive interactions and maintain an organized classroom. The objectives of this study were to (1) identify common types of classrooms based on children’s academic and social-emotional competencies, and (2) examine the relation between classroom compositional profiles and the observed quality of classroom interactions across three domains, while accounting for the quality of interactions in teachers’ classrooms assessed during the prior school year. Participants included 117 third-grade teachers and their 1803 children from 53 urban public elementary schools, in the United States, composed of mostly Black and Latinx children from low-socioeconomic backgrounds. Data were collected as part of a randomized-controlled trial of a social-emotional learning intervention and included assessments of children’s English language arts test scores, social competence, aggressive behaviors, depression, and anxiety, and the observed quality of classroom-level emotional support, classroom organization, and instructional support. Latent profile analysis revealed three distinct profiles: (1) academically and behaviorally high-risk classrooms (9%), (2) academically and emotionally at-risk classrooms (48%), and (3) academically and behaviorally low-risk classrooms (43%). Classrooms in the high-risk profile had significantly lower levels of emotional support, classroom organization, and instructional support, while accounting for teachers’ prior year interactional quality and a set of key teacher and classroom demographic and compositional covariates. Implications for teacher accountability and school tracking practices within high-needs urban public schools are discussed. 相似文献

根据规范场论,自然界各种不同的基本相互作用在实质上都归结为规范场,而“规范对称性”的本质在于“物理定律在变换中保持内在不变性”。按照一般系统论的“不同科学中的同构性”的思想,这种“变换中的不变性”可以推广到包括经济系统和生命系统在内的最一般的系统中去。 相似文献
