This study was designed to examine students’ use of multiple modal representations within their written arguments as a consequence of completing a series of investigations of an organic chemistry laboratory course. One hundred and eleven students from a major Midwestern university were involved in using the Science Writing Heuristic (SWH) approach where they are required to use the argument structure of question, claim, evidence and reflection in completing the written report for their instructor on their laboratory investigations. Results indicate that students who achieved a high score for embedded multiple modal representations in the evidence section also constructed high quality arguments. That is, students who were able to embed multiple modal representations in evidence made strong reasoned connections to support their claim(s) and construct a cohesive argument. Further, there were strong correlations between the laboratory examination score and holistic quality of argument. This study suggests there is a need to build support structures pedagogically for the individual in order to help students understanding the role and function of multiple modal representations in science.  相似文献

This article shares teachers’ conversations within teacher inquiry groups and considers how this reflective approach has potential for transforming teachers’ practices. Conversations took place at the early stages of a longer teacher inquiry project and centred on the critical interrogation of social justice-oriented children’s literature. These conversations served as a forum to help teacher professional learning communities and to reconcile understandings about social justice, action and agency within larger political and cultural forums of teaching. The teacher inquiry sessions shared in this paper explore teachers’ beginning struggles with conceptualizations of social justice, and the teacher’s role in imparting values to students. Teacher participants imparted their experience and practice as they negotiated their own understanding and implementation of social justice education in their schools. The teacher inquiry groups provided a needed supportive space where classroom teachers’ struggles were shared alongside their beliefs and pedagogical approaches so that a social justice agenda could be achieved.  相似文献

It is considered important for students to participate in scientific practices to develop a deeper understanding of scientific ideas. Supporting students, however, in knowing and understanding the natural world in connection with generating and evaluating scientific evidence and explanations is not easy. In addition, writing in science can help students to understand such connections as they communicate what they know and how they know it. Although tools such as vee-maps can scaffold students?? efforts to design investigations, we know less about how these tools support students in connecting scientific ideas with the evidence they are generating, how these connections develop over time, or how writing can be used to encourage such connections. In this study, we explored students?? developing ability to reason scientifically by examining the relationship between students?? understanding of scientific phenomena and their understanding of how to generate and evaluate evidence for their ideas in writing. Three high school classes completed three investigations. One class used vee-mapping each time, one used vee-mapping once, and one did not use vee-mapping. Students?? maps and written reports were rated for understanding of relevant science procedural and conceptual ideas. Comparisons between groups and over time indicate a positive relationship between improved procedural and conceptual understanding. Findings also indicate that improved procedural understanding preceded improved conceptual understanding, and thus, multiple experiences were needed for students to connect evidence and explanation for science phenomena.  相似文献

Teaching is often characterized as an isolated activity, yet opportunities for teachers to work and learn together in schools are increasing. Underlying this shift is the view that as teachers work on new practices and teaching challenges together, they will express varied perspectives, reveal different teaching styles and experiences, and stimulate reflection and professional growth. Despite strong research interest in teacher learning groups, few studies have looked at the relationship between teachers' conversations and collaboration outside the classroom and their actual classroom teaching. Drawing on data from a larger study of literacy instruction with middle‐school teachers, this article describes how three teachers participated in an ongoing literacy program with a research group. Two were seventh‐ and eighth‐grade language‐arts teachers, the third was a special‐education teacher who taught a substantially separate class of cognitively delayed and learning‐disabled students. Case studies of each teacher draw on meeting observations, classroom observations and interviews to describe how each participated in after‐school meetings, how they used the work of the group in the classroom, and how they brought teaching successes and challenges back to the group. Although each of the teachers participated actively in the teacher learning group and changed their practice, the teachers with the most advanced teaching of literacy practices did not bring that expertise into the teacher group as fully as they might have. The analysis raises questions about how teachers participate and learn and how to structure teacher groups to maximize teacher learning.  相似文献

Computer scoring of student written essays about an inquiry topic can be used to diagnose student progress both to alert teachers to struggling students and to generate automated guidance. We identify promising ways for teachers to add value to automated guidance to improve student learning. Three teachers from two schools and their 386 students participated. We draw on evidence from student progress, observations of how teachers interact with students, and reactions of teachers. The findings suggest that alerts for teachers prompted rich teacher–student conversations about energy in photosynthesis. In one school, the combination of the automated guidance plus teacher guidance was more effective for student science learning than two rounds of personalized, automated guidance. In the other school, both approaches resulted in equal learning gains. These findings suggest optimal combinations of automated guidance and teacher guidance to support students to revise explanations during inquiry and build integrated understanding of science.  相似文献

COOPERATIVE TEST CONSTRUCTION: THE LAST TEMPTATION OF EDUCATIONAL REFORM?   总被引:1,自引:0,他引:1  
For decades traditional methods of testing have been criticized for saying relatively little reliably about students’ ability as well as causing anxiety, which can negatively affect students’ recall of learned information. The reform movement with its innovative approaches focusing on learner-centered education perceives assessment as an interactive feedback mechanism, which must provide for active, collaborative reflection by both teacher and students. This means that students must be active participants in designing assessment tasks and be given responsibility for using assessment data to monitor and improve their own learning (Valencia, 1990, p. 339). Focusing on alternative methods of assessment proposed by the opponents of traditional ones, the present study aimed at investigating the impact of cooperative test construction on Iranian EFL (English as a Foreign Language) students’ achievement as well as their attitudes towards such tests. The participants in this study were second- grade high school students (equivalent to Grade 11 in US senior high school) who were assigned to experimental and control groups based on their scores on a standardized retired version of Nelson test. Both groups received the same schedule of instruction for sixteen weeks. The students in the experimental group experienced cooperative test construction while the students in the control group did not have any role in the construction of their tests. The findings revealed statistically significant difference between grammatical knowledge of the students who cooperatively made their own test items and that of those who were tested traditionally. Furthermore, the students’ reactions to cooperative test construction were overwhelmingly positive.  相似文献

This paper emanates from a study that analysed the critical reflection of teacher researchers as they talked about their investigations of the home cultures and literacies of a small group of children from socioculturally diverse family contexts. The collaborative research enterprise was undertaken by university and teacher researchers. The important role that collaborative teacher research and social interaction played in the critical reflection and co-construction of professional understandings in the project is the focus of this paper. The teacher researchers’ theorising about the complexity of their work as a result of the collaborative enterprise is discussed. Through the voiced research and critical reflection of the teachers, it has become obvious that their life’s experiences and resources are powerful in their pedagogical theorising. Teachers comment on the way in which they are positioned by ‘the system’ as technicians and how they experience tension between their own professional and primary discourses and that of the system. It is suggested that teachers be given opportunity within their work sites to enter the conversations about curriculum, pedagogy and change in knowledgeable and meaningful ways that are grounded in collaborative reflection and research. This paper explores the critical reflection and the social construction of new understandings about the complexity of teachers’ work that occurred in a collaborative research project carried out by a university-based researcher and four school-based early years teacher researchers. It will show how the collaborative research process facilitated critical reflection on previously unquestioned or unconsidered issues about the teachers’ work. The paper has been written by the university researcher under the watchful eye of the teacher researchers who want to remain anonymous. Their pseudonyms have been used. When the terms of this project were negotiated among the group, it was agreed that the voices of the teachers would always be reported authentically and anonymously. It was also agreed that any theorising, integrated language analysis (Freeman, 1996) or reporting that might be carried out, would be done by the university researcher That is not to say that the teacher researchers have not spoken about their involvement in the project to colleagues in professional development forums and conferences. Nor is to say that the teachers were not privy to the analysis process. It is to say that written reports for publication are to be done by the university researcher.  相似文献

How does classroom interaction support students’ apprenticeship into the ways of speaking, writing, and diagramming that constitute the practice of mathematics? We address this problem through an interpretative analysis of a whole-group conversation about alternative ways of solving a problem involving percent discounts that occurred in a sixth grade classroom. This research study draws upon Dewey’s theory of inquiry, Vygotsky’s cultural–historical psychology, Freudenthal’s realistic mathematics education, and Halliday’s systemic functional linguistics (SFL). From Freudenthal, we borrow the notions of mathematizing and guided reinvention—the former notion offers a view of mathematics as an activity of structuring subject matter and the latter one provides insights into the processes whereby mathematizing is learned and taught in the classroom. We glean from Dewey his view of reflective thinking as inquiry and the role that conversations may serve therein. We rely upon Vygotsky’s notions of a verbal thinking plane and a social phase of learning in order to reconsider the function of whole-class interaction in apprenticing students into mathematizing. Finally, SFL provides us with tools for explaining the choices of grammar and vocabulary students and teachers make as they realize meanings in whole-group conversations. Treating the selected whole-class conversation as a text, we focus our analysis on how this text came to mean what it did. Our central questions are as follows: What meanings were realized in the whole-class conversation by teacher and students and how were these meanings realized? How did the teacher’s lexico-grammatical choices guide the students’ choices? In addressing these questions, we advance an interpretation of the conversation as paradigmatic of students and teacher thinking aloud together about percents.  相似文献

Curricular and pedagogical reforms are complex inter-linked processes such that curricular reform can only be enacted through teachers teaching differently. This article reports the perspective of emergent Malaysian primary teachers who were expected to implement a Government reform that promoted active learning. The 120 student teachers were members of a single cohort completing a new B.Ed. degree programme in Primary Mathematics designed by teacher educators from Malaysia and the UK. They were taught to use a tripartite pedagogical framework involving action or active learning, supported in practice through reflection and modelling. Drawing on findings from surveys carried out with the student teachers at the end of their first and final placements this article examines evidence for the premise that the student teachers were teaching differently; illustrates how they reported using active learning strategies; and identifies factors that enabled and constrained pedagogic change in the primary classroom. The students’ accounts of using action, reflection and modelling are critiqued in order to learn about changing learning and teaching practice and to contribute to understanding teacher education and early teacher development. The students’ reports suggest diversity of understanding that emphasises the need to challenge assumptions when working internationally and within national and local cultures.  相似文献

This study looks into the reading practice in a Grade 4 knowledge building community that involved 22 students and a veteran teacher. The students investigated light over a three-month period supported by Knowledge Forum, a networked collaborative knowledge-building environment. The classroom designs encouraged the students to take on high-level responsibility for advancing the community’s knowledge, as represented in their online discourse in Knowledge Forum. The tracing of student conversations in Knowledge Forum and content analysis of their portfolio notes demonstrate productive advancement of scientific understanding. Qualitative analyses of classroom videos, online discourse, and the teacher’s reflection journal characterize student reading practice along four themes: reading for the purpose of advancing community knowledge; as progressive problem solving; embedded in sustained knowledge-building discourse; and as dialogues between local understanding and knowledge in the larger world. These results contribute to elaborating the possibility and processes of integrating reading with creative knowledge work in content areas. Classroom strategies are identified and discussed in relation to the role of collaborative online technologies.  相似文献

Coteaching involves 2 or more teachers teaching together. This article describes how to set up coteaching and the advantages for teachers and students associated with it. Cogenerative dialogues are conversations among participants about shared experiences—often in a classroom. The participants include teachers; 2 to 3 students; and, when possible, representatives from other groups such as school administrators and teacher educators. Participants identify contradictions and negotiate agreements on how to resolve them, leading to changes to enact in future lessons and shared responsibility for improving the quality of teaching and learning.  相似文献

This study was part of a multi-year project on the development of elementary students’ modeling approaches to understanding the life sciences. Twenty-three first grade students conducted a series of coordinated observations and investigations on decomposition, a topic that is rarely addressed in the early grades. The instruction included in-class observations of different types of soil and soil profiling, visits to the school’s compost bin, structured observations of decaying organic matter of various kinds, study of organisms that live in the soil, and models of environmental conditions that affect rates of decomposition. Both before and after instruction, students completed a written performance assessment that asked them to reason about the process of decomposition. Additional information was gathered through one-on-one interviews with six focus students who represented variability of performance across the class. During instruction, researchers collected video of classroom activity, student science journal entries, and charts and illustrations produced by the teacher. After instruction, the first-grade students showed a more nuanced understanding of the composition and variability of soils, the role of visible organisms in decomposition, and environmental factors that influence rates of decomposition. Through a variety of representational devices, including drawings, narrative records, and physical models, students came to regard decomposition as a process, rather than simply as an end state that does not require explanation.  相似文献
