In this study we explored how dramatic enactments of scientific phenomena and concepts mediate children's learning of scientific meanings along material, social, and representational dimensions. These drama activities were part of two integrated science‐literacy units, Matter and Forest, which we developed and implemented in six urban primary‐school (grades 1st–3rd) classrooms. We examine and discuss the possibilities and challenges that arise as children and teachers engaged in scientific knowing through such experiences. We use Halliday's (1978. Language as social semiotic: The social interpretation of language and meaning. Baltimore, MD: University Park Press) three metafunctions of communicative activity—ideational, interpersonal, and textual—to map out the place of the multimodal drama genre in elementary urban school science classrooms of young children. As the children talked, moved, gestured, and positioned themselves in space, they constructed and shared meanings with their peers and their teachers as they enacted their roles. Through their bodies they negotiated ambiguity and re‐articulated understandings, thus marking this embodied meaning making as a powerful way to engage with science. Furthermore, children's whole bodies became central, explicit tools used to accomplish the goal of representing this imaginary scientific world, as their teachers helped them differentiate it from the real world of the model they were enacting. Their bodies operated on multiple mediated levels: as material objects that moved through space, as social objects that negotiated classroom relationships and rules, and as metaphorical entities that stood for water molecules in different states of matter or for plants, animals, or non‐living entities in a forest food web. Children simultaneously negotiated meanings across all of these levels, and in doing so, acted out improvisational drama as they thought and talked science. © 2009 Wiley Periodicals, Inc.

Patterns of verbal communications between a teacher and student can influence the classroom environment, quality of the instructional program, and student management in the classroom. This study examined teacher-student communication patterns in both regular and special education classes for behaviorally and emotionally handicapped students. It was expected that special class communication patterns would differ substantially from those used in regular classes. Those communications would result in more effective student management and more time on-task for learning. Webster's (1984, 1986) Process Interaction Model was used to analyze the communication patterns. Expected differences between how regular and special class teachers interact with students were not found. Implications of findings are discussed in relationship to teacher training, teacher effectiveness, and classroom management.  相似文献

Drawing on theories of student motivation to learn and conceptual change learning in science, this article describes five patterns of student motivation observed in sixth-grade science classrooms: (a) intrinsically motivated to learn science; (b) motivated to learn science; (c) intrinsically motivated but inconsistent; (d) unmotivated and task avoidant; and (e) negatively motivated and task resistant. These motivational patterns were related in theoretically predictable ways with the learning strategies and other behaviors that the students exhibited in the classrooms. The study highlights the value of distinguishing motivation to learn from intrinsic motivation, and of distinguishing general motivational traits from situation-specific motivational states. The study also highlights the importance of considering subject-matter content in classroom motivation. Implications for motivation research and classroom practices are discussed. © 1996 John Wiley & Sons, Inc.  相似文献

The implementation of formative assessment strategies is challenging for teachers. We evaluated teachers’ implementation fidelity of a curriculum-embedded formative assessment programme for primary school science education, investigating both material-supported, direct application and subsequent transfer. Furthermore, the relationship between implementation fidelity and teacher variables was explored. N = 17 German primary school teachers participated in professional development on formative assessment, N = 11 teachers formed a control group. Teachers’ implementation fidelity was evaluated via classroom observations student ratings and an analysis of students’ workbooks, focusing on the frequency and quality of intended formative assessment elements (assessments, feedback and instructional adaptations). Regarding direct application, treatment group teachers’ implementation fidelity was high, with slight variations in quality. Regarding transfer, implementation fidelity was lower but teachers still implemented more formative assessment elements than the control group. Teachers’ pedagogical content knowledge and their evaluation of the formative assessment intervention were associated with implementation success.  相似文献

This symbolic interaction study was designed to identify and discover key components about caring science teachers. Grounded theory was generated that emphasizes the notion that caring is important in today's schools and provides insight into what happens in science classrooms. A key pattern that emerged regarding science teachers who are perceived to be caring is that they build a variety of relationships. The kinds of relationships described as caring by the teachers in this study include teacher-student, student-student, and teacher-content. The interaction and integration of these three kinds of relationships results in teacher-student-content relationships. The emergence of relationships and illustrations of the importance of these relationships is described herein. © 1996 John Wiley & Sons, Inc.  相似文献

Conclusion It is apparent from the data that pupils use a wide variety of techniques to aid the clarity of their drawings and that they are able to discriminate between them. The data support the value of the teaching method used, where drawings were used as the principal means of communication between the children. The study has shown how, without any teacher instruction on drawing techniques, the children have been able to identify and adapt ones which they see as meeting their requirements. The study has established one teaching method which, following further investigation, could be presented to teachers as a useful strategy during science lessons.  相似文献

This study further extends a conceptual framework that explores science teaching as a “practice” not reducible to the application of formal knowledge, but as informed by teachers' practical‐moral knowledge. A hermeneutic model was developed to examine practical‐moral knowledge indirectly by investigating teachers' commitments, interpretations, actions, and dialectic interactions between them. The study also aimed to analyze teachers' actions in terms of their interpretations and commitments as they realize “internal goods” of their practice. Ethnographic case studies of three science teachers were conducted through classroom observation, in‐depth interviews and dialogues, and artifact analysis. A commitment of preparing students for national exams was common to the three teachers but was manifested differently in classroom practices. This commitment originated from interpretations about the duty of “good” teachers not letting students and schools down. Other emergent commitments were commitments: to conceptual understandings, to “challenge” learners, and to social modeling. We present each with associated interpretations and actions. The concepts of practical wisdom (phronesis) and gap closing are used to characterize teachers' practical knowledge and its development respectively. Implications for teacher education are discussed. © 2010 Wiley Periodicals, Inc. J Res Sci Teach 47: 929–951, 2010  相似文献

Religious beliefs in science classrooms   总被引:3,自引:0,他引:3  
The question of the relationship between science and religion assumes importance for many secondary school students of science, especially but not exclusively for those in Christian schools. Science as presented in many school classrooms is not as objective and value free as it might seem on first examination, nor does it represent adequately the range of beliefs about science held by students and teachers. This paper reports part of a larger research study into beliefs about science and religion held by students, teachers and clergy in a Lutheran secondary school. Results indicate that participants in the study was the relationship between science and religious belief in ways unforeseen and unappreciated by traditional school science programs. The stories of selected participants are told and they frame a discussion of implications of the study for science teaching.  相似文献

The paper explores the ways girls appropriate gender through actions, gesture and talk to achieve things in primary school science classrooms. It draws on socio-cultural approaches to show that when everyday classroom practices are viewed from multiple planes of analysis, historical, institutional and in the micro dynamics of classroom interaction, gender comes into view in a variety of ways and not only via dominant discourses. Focused observations and interviews were carried out in Year 3 primary school science classrooms in four schools in the UK and the USA (children aged 7 and 8 years). The paper suggests how teachers can work with gender to open up new spaces in primary science classrooms for girls. This remains a priority irrespective of the contemporary anxieties around boys’ achievement if girls are to grow up feeling that science is a legitimate arena in which to participate.  相似文献

A large scale observational study by educational psychologists of 141 UK primary classrooms used a partial interval time‐sampling observational schedule to record the frequency and type of verbal behaviour of teachers and whether students were “on‐task” (following the teacher’s directions) or “off‐task” (not following the teacher’s directions).

Results were analysed and comparisons made between lessons that followed National Literacy Strategy or Numeracy guidelines and those that did not; between schools from different geographical contexts, e.g. rural or inner‐city; between classes where there was one, or more than one, adult present; between schools with different percentages of free school meals; and between a.m. and p.m. lessons.

A range of findings included higher rates of students being on‐task than found by previous studies, and correlations between high on‐task rates and teachers who used high levels of verbal behaviour including positive academic feedback. Teachers used three times more verbal approval for desired social behaviour in the classroom than has been reported in previous studies. It was found that teachers verbally interacted more with students during National Literacy and Numeracy Strategy lessons but that this did not lead to statistically significantly higher on‐task rate. Similarly, teachers in inner‐city schools interacted more with students, but on‐task rates in inner‐city schools were not significantly higher. Reasons for this effect are discussed.  相似文献

This study evaluated the effects of cooperative learning on students' verbal interaction patterns and achievement in a conceptual change instructional model in secondary science. Current conceptual change instructional models recognize the importance of student–student verbal interactions, but lack specific strategies to encourage these interactions. Cooperative learning may provide the necessary strategies. Two sections of low-ability 10th-grade students were designated the experimental and control groups. Students in both sections received identical content instruction on the particle model of matter using conceptual change teaching strategies. Students worked in teacher-assigned small groups on in-class assignments. The experimental section used cooperative learning strategies involving instruction in collaborative skills and group evaluation of assignments. The control section received no collaborative skills training and students were evaluated individually on group work. Gains on achievement were assessed using pre- and posttreatment administrations of an investigator-designed short-answer essay test. The assessment strategies used in this study represent an attempt to measure conceptual change. Achievement was related to students' ability to correctly use appropriate scientific explanations of events and phenomena and to discard use of naive conceptions. Verbal interaction patterns of students working in groups were recorded on videotape and analyzed using an investigator-designed verbal interaction scheme. The targeted verbalizations used in the interaction scheme were derived from the social learning theories of Piaget and Vygotsky. It was found that students using cooperative learning strategies showed greater achievement gains as defined above and made greater use of specific verbal patterns believed to be related to increased learning. The results of the study demonstrated that cooperative learning strategies enhance conceptual change instruction. More research is needed to identify the specific variables mediating the effects of cooperative learning strategies on conceptual change learning. The methods employed in this study may provide some of the tools for this research.  相似文献

To understand students’ argumentation abilities, there have been practices that focus on counting and analyzing argumentation schemes such as claim, evidence, warrant, backing, and rebuttal. This analytic approach does not address the dynamics of epistemic criteria of children’s reasoning and decision-making in dialogical situations. The common approach also does not address the practice of argumentation in lower elementary grades (K–3) because these children do not master the structure of argumentation and, therefore, are considered not ready for processing argumentative discourse. There is thus little research focusing on lower elementary school students’ argumentation in school science. This study, drawing on the societal-historical approach by L. S. Vygotsky, explored children’s argumentation as social relations by investigating the genesis of evidence-related practices (especially burden of proof) in second- and third-grade children. The findings show (a) students’ capacity for connecting claim and evidence/responding to the burden of proof and critical move varies and (b) that teachers play a significant role to emphasize the importance of evidence but experience difficulties removing children’s favored ideas during the turn taking of argumentative dialogue. The findings on the nature of dialogical reasoning and teacher’s role provide further insights about discussions on pedagogical approaches to children’s reasoning and argumentation.  相似文献

Twenty-six junior high and middle school science classes taught by 13 teachers were observed frequently during the first 2 months of school and during 2 months in the middle of the year to identify classroom management and instructional organization variables related to high levels of student task engagement and low levels of off task and disruptive behavior. Sub-samples of more and less effective managers were identified, and narrative data from their classes were analyzed to describe and illustrate effective strategies for managing science classroom activities.  相似文献

Advancements in information and communications technology and the rapid expansion of the Internet have changed the nature and the mode of the presentation and delivery of teaching and learning resources. This paper discusses the results of a study aimed at investigating how five teachers planned to integrate online resources in their teaching of science topics in the primary curriculum. Based on the findings obtained from the content analysis of the teaching designs created by the participating teachers, and insights gained from the pre- and post-lesson implementation interviews with them, a resource-based e-learning environments (RBeLEs) framework is proposed as an outcome which could be of reference as a planning tool for teachers who wish to integrate the Internet into their classroom teaching.  相似文献

Purpose: This study examines how different purposes can support teachers in their work with progressions as a part of a teaching sequences in science in primary school.

Design/Method: The study was carried out in two classes working with inquiry and the events that took place in the classroom were filmed. In the study, we have chosen to use the technical term proximate purposes for the student-oriented purposes, and ultimate purposes for the scientific purposes. Together, these two types of purposes form the organisational purposes for the classes. Proximate purposes work in such a way that students can use their language and relate to their experiences as ends-in-view. To examine how organising purposes can be used to analyse progressions, we discuss examples from two different lessons.

Result: The study shows the importance of proximate purposes working as ends-in-view and also demonstrates how the teacher and students may create continuity in teaching to enable progression as a part of a teaching sequence.

Conclusions: To create continuity, it was essential that the teacher scaffolded the students in ways which allowed the students to explicitly differentiate between what was relevant or not, about the proximate purposes in relation to the ultimate purpose.  相似文献
