Peer feedback is an inherent feature of classroom collaborative learning. Students invariably turn to their peers for feedback when carrying out an investigative task, and this feedback is usually implicit, unstructured and may positively or negatively influence students’ learning when they work on a task. This study explored the characteristics of verbal peer feedback during a collaborative investigative chemistry task involving New Zealand Year 13 students. During the planning stage of the students’ investigation, the discussions of five pairs of students were recorded and then transcribed. Analysis of transcribed verbal data focused on interactions that involved peer feedback along two dimensions, interactive/non-interactive and dialogic/authoritative (Mortimer and Scott, 2003). The findings indicated that although students adopted a predominantly interactive/authoritative communicative approach, with peer feedback as confirmation or evaluation, they are also capable of a more interactive/dialogic exchange, characterised by elaborative peer feedback. We discuss how this dialogic perspective on peer feedback provides an alternative approach to the analysis and study of student–student interactions during science investigations. The findings should be interpreted in light of the limitations in terms of sample size, grouping and specificity of the coding scheme. Implications for teacher practice are discussed in relation to facilitating peer feedback discourse in the science classroom. 相似文献

The first purpose of the present study was to examine the effect of dialogic classroom talk on children's language skills (i.e. oral communicative competence and receptive vocabulary knowledge). The second purpose was to examine the effect of this type of classroom talk on children's social competence (i.e. theory of mind and social acceptance). A total of 17 teachers and 311 children (aged 4–7 years) participated in this study. Eight teachers participated in an 8-week intervention directed at dialogic classroom talk. Multilevel analyses revealed that the intervention had a significant effect on children's oral communicative competence. No significant effects were found on children's receptive vocabulary knowledge, theory of mind, and social acceptance. The results of this study indicate that dialogic classroom talk is beneficial for children's oral communicative competence. Further research is required in order to investigate how dialogic classroom talk might affect receptive vocabulary knowledge and social competence as well. 相似文献

The complexity of words makes vocabulary development a multi-faceted process that presents challenges to early childhood educators,
offers benefits to young learners, and must be supported through evidence-based strategies. All students, regardless of socio-economic
status or background, need to make significant gains in receptive and expressive vocabulary at home and at school each year
in order to support their growth in literacy. Students from low socioeconomic backgrounds and those students who speak English
as a second language are particularly at risk of failing to make proficient vocabulary gains. The most effective way for early
childhood educators to enhance the vocabulary development of all students is to implement evidence-based strategies for teaching
vocabulary. A key finding in the research is that young children need to be actively engaged in vocabulary development if
they are to remember new words and begin to grasp the multiple, nuanced meanings of words. Other effective vocabulary instruction
practices include meaningful repetition; combining the enactive, iconic, and symbolic modes; and reading aloud in a dialogic
style. In light of the trend in the research data that links the child’s vocabulary level to gains in reading comprehension,
early childhood educators have a special obligation to teach vocabulary more effectively. 相似文献

Teacher–student discourse continues to be teacher-centred even though researchers and reform documents have recommended changes toward increased levels of student-centred discourse. In science education this situation is paralleled by effort to make scientific inquiry more student-centred. The purpose of this study was to investigate how discourse forms changed over time in a classroom where the regular teacher and his students were scaffolded in the transitioning to student-centred scientific inquiry. Video-recordings were collected at intervals over one academic year. Three prominent forms of discourse were identified: two teacher-authoritative forms and one more interactive, dialogic form. As the lessons increasingly turned into student-centred scientific inquiry, a shift to the dialogic discourse form was found. Co-teaching provided for (a) guidance towards an organisation of events in the classroom that included regular teacher–student dialogue (b) modelling of the more dialogic form of discourse. 相似文献

Phenomena-based approaches have become popular for elementary school teachers to engage children's innate curiosity in the natural world. However, integrating such phenomena-based approaches in existing science courses within teacher education programs present potential challenges for both preservice elementary teachers (PSETs) and for laboratory instructors, both of whom may have had limited opportunities to learn or teach science within the student and instructor roles inherent within these approaches. This study uses a convergent parallel mixed-methods approach to investigate PSETs' perceptions of their laboratory instructor's role within a Physical Science phenomena-based laboratory curriculum and how it impacts their conceptual development (2 instructors/121 students). We also examine how the two laboratory instructors' discursive moves within the laboratory align with their's and PSETs' perceptions of the instructor role. Qualitative data includes triangulation between a student questionnaire, an instructor questionnaire, and video classroom observations, while quantitative data includes a nine-item open response pre-/post-semester conceptual test. Guided by Mortimer's and Scott's analytic framework, our findings show that students primarily perceive their instructors as a guide/facilitator or an authoritarian/evaluator. Using Linn's knowledge integration framework, analysis of pre-/post-tests indicates that student outcomes align with students' perceptions of their instructors, with students who perceive their instructor as a guide/facilitator having significantly better pre-/post-outcomes. Additional analysis of scientific discourse from the classroom observations illustrates how one instructor primarily supports PSETs' perspectives on authentic science learning through dialogic–interactive talk moves whereas the other instructor epistemologically stifles personally relevant investigations with authoritative–interactive or authoritative–noninteractive discourse moves. Overall, this study concludes by discussing challenges facing laboratory instructors that need careful consideration for phenomena-based approaches. 相似文献

Reflection on the relationship between a sign and its meaning (i.e. semiotic activity) is a fundamental form of cognitive activity that already occurs at an early age. The improvement of this semiotic activity in young children prepares for their later learning activity. Iconic representations are one important category of signs for young children (3‐7 years old). Iconic representations (drawings, diagrams, schemes) are generally conceived of as means bridging the gap between early enactive, perception‐bound thinking and abstract‐symbolical thinking. From the Vygotskian perspective iconic representations are complex signs referring to some object (situation, action) in a special way. On the bases on the analysis of children's drawings it is argued that iconic representations are narrative in nature for young children. Children tend to supplement their drawings with verbal symbols in order to make sure that their intended meanings are maximally clear. In doing so, children learn to carry out semiotic activity and improve this activity with the help of more abstract symbols 相似文献

Representations are used extensively in mathematics and translation ability is highly correlated with success in mathematics education. The authors investigate the translation ability of university students as far as the concept of function is concerned. The research focuses on the relationship between success in, solving direct translation tasks and success in solving problems by articulating different representations of the concept of function. Furthermore, it examines the relationship between student performance and the nature of the representation included in the translation task. The ability to pass from one representation to another was associated with success in problem solving. These results indicate that translation ability should be considered as an important factor in problem solving. Percentages are lower when an iconic representation is included in the translation task. This could be partly attributed to the holistic nature of iconic representations and to the way the concept of function is taught at secondary schools. 相似文献

ObjectiveThe present study investigated the direction of the relation between oral communicative competence and social preference in early childhood classrooms. Additionally, we explored the role of dialogic classroom talk in this relation.MethodsN = 311 children (aged four to seven) participated. Oral communicative competence was measured with the Nijmegen Test for Pragmatics and social preference was assessed with a peer nomination method (both constructs measured at two timepoints).ResultsOutcomes of cross-lagged analyses demonstrated a directional link from social preference to oral communicative competence, but not the other way around. There were no differences in the relation between the two constructs between classrooms in which dialogic classroom talk was implemented and classrooms in which it was not.ConclusionThis study seems to indicate the importance of children's social preference for developing adequate communicative abilities. 相似文献

It is commonly believed that science teachers rely on language that allows only minor flexibility when it comes to taking
into account contrasting views and pupil thoughts. Too frequently science teachers either pose questions that target predefined
answers or simply lecture through lessons, a major concern from a sociocultural perspective. This study reports the experiences
of science student teachers when introduced to the Communicative Approach to science education drawing on dialogic teacher-talk
in addition to authoritative teacher-talk. This approach was introduced to the students in an interventional teaching program
running parallel to the student teachers’ field practice. The practical implications of this approach during initial teacher
education are the central focus of this study. The data consisting of videos of lessons and interviews indicate that the student
teacher awareness of teacher-talk and alternative communicative options did increase. Student teachers reported greater awareness
of the different functions of teacher-talk as well as the challenges when trying to implement dialogic teaching. 相似文献

Over the past three decades, research and policy in many geographic regions has promoted a shift from direct, lecture-oriented mathematics instruction to inquiry-based, dialogic forms of instruction. While theory and research support dialogic instructional approaches, some have noted that the complexities of dialogic teaching make it difficult for teachers to implement. One mechanism by which teachers can improve their decision-making practices in dialogic classrooms is learning to notice (i.e. becoming aware of learners’ processes). While research has contributed frameworks for understanding how teachers notice individual learners’ mathematical thinking, there is little conceptualization regarding how teachers notice group processes in mathematics classrooms, which is integral to dialogic instruction. We offer a noticing framework termed professional noticing of coordinated mathematical thinking that describes how teachers notice group activity in mathematics classrooms. Professional noticing of coordinated mathematical thinking is conceptualized as a bi-dimensional process: noticing groups’ mathematical activity and noticing groups’ coordinated activity. Teachers must become aware of how groups approach the mathematical and collaborative nature of a task, since both of these aspects inform whether learners develop opportunities to learn in groups. The framework describes noticing practices integral to dialogic instruction and promotes inquiry for future research related to teaching moves in dialogic classrooms. 相似文献

Chemistry concepts in three 2‐week modules were presented to a treatment and control group of high school students from 10 different high schools. The treatment group was taught using three representations of matter (macroscopic, particulate, and symbolic), whereas only two representations (macroscopic and symbolic) were used with the control group. The treatment group scored significantly higher across the combined score of all three modules. When the data were analyzed for gender–group interactions, females who were taught the particulate representation scored as well as males whereas those who were not taught the particulate representation scored significantly lower than males. Teaching males the particulate representation did not significantly affect males' achievement. © 2002 Wiley Periodicals, Inc. J Res Sci Teach 39: 911–927, 2002 相似文献

Students' mental load,stress, and performance when working with symbolic or symbolic–textual molecular representations

下载免费PDF全文 In science education, representations are necessary inter alia for the understanding of relationships between structures and systems. However, several studies have identified difficulties of students when working with representations. In the present study, we investigated students' responses (regarding their preference, test performance, mental load (ML), and stress) toward two kinds of representations: symbolic representations, which only use abstract symbols, versus combined symbolic–textual representations, which additionally comprise textual elements. Therefore, students were randomly assigned to one of two treatment groups: one group worked on test tasks accompanied by symbolic representations, and the others worked on the same tasks, but with symbolic–textual representations. Thereafter, the students' test performance and ML were assessed. The level of perceived stress and the salivary cortisol concentration were measured before and after the test and again a few minutes later. Additionally, heart rate variability parameters were assessed continuously. We found a strong preference of the test version with symbolic representations. Additionally, the students showed better test performance and lower ML when they worked with symbolic representations. However, the level of perceived stress was comparable between both groups and there was no strong physiological stress response: The cortisol concentration decreased in both groups and the heart rate was relatively similar. However, during the second half of the test, we observed a significantly higher ratio between low and high heartbeat frequencies in the group with symbolic–textual representations and we found an indirect influence of the kind of representation on test performance through its effect on ML. The poorer test performance and higher ML in connection with symbolic–textual representations confirm previous studies, which found that symbolic–textual representations pose major problems for students. Thus, teachers should enable students to understand symbolic–textual representations and consider carefully whether they can use symbolic representations instead, especially when they teach complex content. 相似文献

There has been much concern with the ideas of interactive and dialogic teaching during recent years in the UK, ideas which
have emerged from international comparisons. This paper concerns a research project in Wales which sought to explore how the
interactive features of information and communication technology (ICT) support interactivity in teaching. The project found
that much use of ICT by good teachers was at a relatively superficial level of interaction, yet when teachers used a deeper,
more dialogic, level of interactivity in teaching, they achieved improvements in learning whether they used ICT or not. The
potential of ICT to support more dialogic teaching was not being fully exploited. The paper reports the findings of the classroom
observation dimension of the project, and examines the implications for pedagogical practices and the development/dissemination
of ICT resources which can support more dialogic interactivity. 相似文献

象似性手势是指在形式和表达方式上与其所伴随的言语的语义内容密切相关的手势。儿童通常在18~24个月产生象似性手势,到3岁时能准确理解象似性手势的含义。象似性手势的产生和理解与儿童年龄呈正相关,且受文化等社会因素的影响较大。象似性手势能够揭示儿童的象征发展水平,解释并再现言语组织过程,补充言语中未表达的信息,促进多通道表征,提高词汇加工效率,因而有助于儿童的词汇理解、记忆和泛化。未来相关研究应进一步扩大象似性手势的研究对象,考察象似性手势与具身认知的关系及其对儿童词汇学习的多方面影响,这将有助于提高未来研究成果对教育实践的指导作用。 相似文献

Drawing on qualitative data, this article presents an analysis of six secondary science teachers’ expectations and practices related to teaching outdoors during a professional development programme. Using Foucault’s and Bernstein’s theories of ‘space’, routines and set practices, I argue that participant teachers’ fear of losing control of their students when in contexts outside the classroom was constructed as place specific in terms of boundaries (or lack of), familiarity and disturbance. Teachers’ ‘fearful’ expectations when outside triggered the initial use of regulatory technologies that were frequently more assertive and controlling than their usual classroom practice, resulting in increased authoritative teaching approaches. However, once technologies of power were developed for use outside, teachers were able to translate and apply their normal dialogic teaching approaches from the classroom. The article concludes with a discussion of student self-regulation through collaborative group work as a step towards resolving the tensions between dialogic pedagogy and teaching in new contexts. 相似文献

This paper describes the design and development of an interactive learning environment inspired from the constructivist view of learning and aiming at helping students improve their conceptions about chemical equilibrium. The design of the software was based on data that emerged from research we undertook with 175 Greek students (aged 17–18), in order to detect their conceptions and learning difficulties about chemical equilibrium. The students' answers to a written questionnaire showed that they had inadequate representations of systems of substances at chemical equilibrium related to the empirical and the atomic level, manifested serious difficulties in conceiving the initial situation of a system at chemical equilibrium and the equilibrium shift, made overextended use of the Le Chatelier principle and applied intuitive personal rules instead of the equilibrium constant law. The aim of this computer application is to help students to create and/or improve their own representations about substances at chemical equilibrium in the empirical, atomic and symbolic level, to establish appropriate links among thes multiple representations, and to construct appropriate conceptions about the Le Chatelier principle and the equilibrium constant law. The software contains simulations and visualizations of experiments representing systems at chemical equilibrium, simulations of chemical reactions related to the atomic level, symbolic representations and dynamic graphs, and a step-by-step derivation of the equilibrium constant law. 相似文献
