This forum considers argumentation as a means of science teaching in South African schools, through the integration of indigenous knowledge (IK). It addresses issues raised in Mariana G. Hewson and Meshach B. Ogunniyi’s paper entitled: Argumentation-teaching as a method to introduce indigenous knowledge into science classrooms: opportunities and challenges. As well as Peter Easton’s: Hawks and baby chickens: cultivating the sources of indigenous science education; and, Femi S. Otulaja, Ann Cameron and Audrey Msimanga’s: Rethinking argumentation-teaching strategies and indigenous knowledge in South African science classrooms. The first topic addressed is that implementation of argumentation in the science classroom becomes a complex endeavor when the tensions between students’ IK, the educational infrastructure (allowance for teacher professional development, etc.) and local belief systems are made explicit. Secondly, western styles of debate become mitigating factors because they do not always adequately translate to South African culture. For example, in many instances it is more culturally acceptable in South Africa to build consensus than to be confrontational. Thirdly, the tension between what is “authentic science” and what is not becomes an influencing factor when a tension is created between IK and western science. Finally, I argue that the thrust of argumentation is to set students up as “scientist-students” who will be considered through a deficit model by judging their habitus and cultural capital. Explicitly, a “scientist-student” is a student who has “learned,” modeled and thoroughly assimilated the habits of western scientists, evidently—and who will be judged by and held accountable for their demonstration of explicit related behaviors in the science classroom. I propose that science teaching, to include argumentation, should consist of “listening carefully” (radical listening) to students and valuing their language, culture, and learning as a model for “science for all”.  相似文献

This forum discussion focuses on seven themes drawn from Sonya’s fascinating paper: the terminology of “cogenerative dialogues,” the roles of participants and their power relations within such dialogues, the use of metaphor and analogy in the paper, science and science education for all students, the ways in which students’ expectations about learning change in innovative classrooms, teacher research and the “theory-practice gap,” and the tension between conducting cogenerative dialogues with individual students or with whole classes. These themes by no means exhaust the ideas in Sonya’s paper, but we feel that they have allowed us to explore the classroom research she reports, and to extend our discussion beyond the paper to explore some of these themes more broadly.  相似文献

We analyse and explore, in the form of dialogues and metalogues questions about the dialogic nature of beliefs and students belief talk about the nature of science and scientific knowledge. Following recent advances in discursive psychology, this study focuses not on students' claims but on the discursive resources and dialogical practices that support the particular claims they make. We argue that students' discourse is better understood as a textual bricolage that is sensitive to conversational context, common sense, interpretive repertoires, and textual resources available in the conversational situation. Our text is reflexive as it embodies the discursive construction of knowledge and undercuts any claims to authoritative knowledge. The very conception of “belief” is itself an expression or construction from within the mundane idiom.... We learn to use “belief” in conditions when the “objective facts” are unknown or problematic and we want to indicate the tenuous character of our claim.... The notion of “real world” or “objective reality” is embedded in an extensive, pervasive language game which includes as an intelligible move or possibility the use of the very concept of “belief” itself.

This article is a response to Randy Yerrick and Joseph Johnson’s article “Negotiating White Science in Rural Black America: A Case for Navigating the Landscape of Teacher Knowledge Domains”. They write about research conducted by Yerrick in which videos of his teaching practice as a White educator in a predominately Black rural classroom were examined. Their analysis is framed through Shulman’s (1986) work on “domains of teacher knowledge” and Ladson-Billings’ (1999) critical race theory (CRT). Although we appreciate a framework that attends to issues of power, such as CRT, we see a heavier emphasis on Shulman’s work in their analysis. We argue that a culturally relevant pedagogy (CRP) framework has the potential to provide a more nuanced analysis of what occurred in Yerrick’s classroom from a critical lens. Thus we examine Yerrick and Johnson’s work through the five main CRP components (as defined by Brown-Jeffy and Cooper 2011) and ultimately argue that science educators who want to promote equity in their classrooms should engage in continuous critical reflexivity, aid students in claiming voice, and encourage students to become not only producers of scientific knowledge but also users and critics of such knowledge.  相似文献

Scientific Habits of Mind in Virtual Worlds   总被引:8,自引:6,他引:2  
In today’s increasingly “flat” world of globalization (Friedman 2005), the need for a scientifically literate citizenry has grown more urgent. Yet, by some measures, we have done a poor job at fostering scientific habits of mind in schools. Recent research on informal games-based learning indicates that such technologies and the communities they evoke may be one viable alternative—not as a substitute for teachers and classrooms, but as an alternative to textbooks and science labs. This paper presents empirical evidence about the potential of games for fostering scientific habits of mind. In particular, we examine the scientific habits of mind and dispositions that characterize online discussion forums of the massively multiplayer online game World of Warcraft. Eighty-six percent of the forum discussions were posts engaged in “social knowledge construction” rather than social banter. Over half of the posts evidenced systems based reasoning, one in ten evidenced model-based reasoning, and 65% displayed an evaluative epistemology in which knowledge is treated as an open-ended process of evaluation and argument.  相似文献

In this paper a conceptual model of instruction “the six mirrors of the classroom” used as a frame for teaching a learning topic, the microorganisms are depicted. The paper consists of four sections: (a) the six mirrors of the classroom model (SMC); (b) the SMC as implemented in the expository and cooperative modes of instruction in classrooms and results; (c) a “Journey of Inquiry into the Wonderful World of Microorganisms” (JIWWM), developed according to the Science–Technology–Environment–Peace–Society (STEPS) approach; and (d) teaching and learning the JIWWM, in ninth-grade classes, within the SMC model. The results show that science topic can be taught in the frame of the mirrors of the classroom. When the instructional goals of the teachers used the mirror “1, classroom organization” and mirror “6, pupils’ social behavior” and the third ring around the all six mirrors cooperative skills were practiced, academic outcomes were achieved, and attitudes toward environmental preservation and peace improved. The SMC model can serve as a valuable tool for teachers, since it can design their teaching and learning settings in a more controlled environment, in terms of objectives, teachers’ and students’ social behaviors, and academic outcomes.  相似文献

Maria Andrée focuses on an immigrant student whose error in a laboratory activity leads to a novel, colorful outcome that she excitedly shares with peers. After engaging in class activities for a few weeks she returns to her earlier dislike of science, saying: "I hate science, particularly Chemistry." The classroom activity system focused on reproduction of school knowledge did not expand to accommodate Helena's “new activity system with an object of learning science.” This essay suggests teachers be prepared to teach diverse students in ways supporting multiple ways to engage in science. This becomes possible when teachers view their classrooms as dynamic, participatory activity systems that support content mastery as contributing to but not being identical to science identity and science literacy.  相似文献

The empirical study, in this article, involved 42 students (ages 14–15), who used the urban simulation computer game SimCity 4 to create models of sustainable future cities. The aim was to explore in what ways the simulated “real” worlds provided by this game could be a potential facilitator for science learning contexts. The topic investigated is in what way interactions in this gaming environment, and reflections about these interactions, can form a context where the students deal with real world problems, and where they can contextualise and apply their scientific knowledge. Focus group interviews and video recordings were used to gather data on students’ reflections on their cities, and on sustainable development. The findings indicate that SimCity 4 actually contributes to creating meaningful educational situations in science classrooms, and that computer games can constitute an important artefact that may facilitate contextualisation and make students’ use of science concepts and theories more explicit.  相似文献

This study investigated preschool science environments in 20 preschool classrooms (N=20) in 13 midwestern child care centers. By operationalizing Neuman’s concept of “sciencing,” this study used The Preschool Classroom Science Materials/Equipment Checklist, the Preschool Classroom Science Activities Checklist, and the Preschool Teacher Classroom/Sciencing Form to analyze the availability of science materials, equipment, and activities for preschoolers in the classroom. Each teacher was videotaped for two consecutive days during free play time. The study showed that half of the preschool classrooms had a science area. The activities that the preschool teachers engaged were mostly unrelated to science activities (86.8%), 4.5% of the activities were related to formal sciencing, and 8.8% of the activities were related to informal sciencing.  相似文献

This paper reports multi-layered analyses of student learning in a science classroom using the theoretical lens of Distributed Cognition (Hollan et al. 1999; Hutchins 1995). Building on the insights generated from previous research employing Distributed Cognition, the particular focus of this study has been placed on the “public space of interaction” (Alac and Hutchins 2004, p. 639) that includes both participants’ interaction with each other and their interaction with artefacts in their environment. In this paper, a lesson from an Australian science classroom was examined in detail, in which a class of grade-seven students were investigating the scientific theme of gravity by designing pendulums. The video-stimulated post-lesson interviews with both the teacher and the student groups offered complementary accounts (Clarke 2001a) that assisted the interpretation of the classroom data. The findings of this study provide supporting evidence to demonstrate the capacity of Distributed Cognition for advancing our understanding of the nature of learning in science classrooms.  相似文献

This paper looks at the distinctions between science classrooms and the robotics competition described in the article “Examining the mediation of power in a collaborative community: engaging in informal science as authentic practice” written by Anton Puvirajah, Geeta Verma and Horace Webb. Using the framework of “productive disciplinary engagement” and discussing each principle in turn, the article argues that in order to bring the advantages of informal learning environments into regular classrooms we especially need to address student interest through task design and to change curricular requirements to agree with changing educational values.  相似文献

In this article I argue that the use of practical reasoning in university classrooms is necessary to establish conditions under which university teachers and students can move beyond the dominant “transmission mode” of education (teaching and learning). This mode of education had been, and in many cases remains to be prevalent in several (South African) university classrooms. I argue what it could mean for university teachers and students to reason together with one another in classroom practices. Central to reasoning together is the idea of deliberation which provides opportunities for teachers and students to experience “intelligent action” (Biesta 2004a) that could enhance educational problem solving in (and beyond) university classrooms.  相似文献

In this article we offer a theoretical discussion of teachers' mathematics-for-teaching, using complexity science as a framework for interpretation. We illustrate the discussion with some teachers' interactions around mathematics that arose in the context of an in-service session. We use the events from that session to illustrate four intertwining aspects of teachers' mathematics-for-teaching. We label these aspects “mathematical objects,” “curriculum structures,” “classroom collectivity,” and “subjective understanding”. Drawing on complexity science, we argue that these phenomena are nested in one another and that they obey similar dynamics, albeit on very different time scales. We conjecture (1) that a particular fluency with these four aspects is important for mathematics teaching and (2) that these aspects might serve as appropriate emphases for courses in mathematics intended for teachers.  相似文献

A science teacher and her mentor reflect on their participation in the Learning Research Cycle, a professional learning model that bridges research and practice in both university and public school contexts. Teachers do scientific research in scientists’ laboratories, then bridge their scientific experiences with the design of new classroom learning environments and teacher-driven educational research projects. Science students do scientific research via their teachers’ lessons that bridge laboratory research with classroom learning. Scientists and educational researchers bridge their research interests to create new questions centered on teaching and learning in authentic science learning environments. The authors engaged in this qualitative inquiry present their perspectives on “what goes on,” “what we have learned,” and “what it means to the larger community.”  相似文献

Research in Mexican schools, drawing upon earlier research in the UK, has led to the development and use of a method for describing, comparing and evaluating the particular approaches and interactional strategies used by teachers and learners. Using this method, qualitative and quantitative comparisons are made to distinguish between teachers who use a conventional, formal, directive approach when teaching 5-year-old children mathematical skills (called the “Official” method) and those who use a more interactive, collaborative, supportive, “scaffolded” approach to teach similar classes of children (called the “High Scope” method). In an earlier study, we found more competent and independent problem-solving among High/Scope pupils than among their peers taught by the Official method. In the present study, discourse analysis and statistical analysis of the relative frequencies of types of teacher-pupil interaction in the classrooms of two “Official” teachers and two “High’ Scope” teachers are used to explain the improved problem-solving of the “High Scope” pupils. The findings support the view that by creating a more collaborative, scaffolded version of classroom education, teachers can more successfully enable children to develop their own problem-solving skills, learning strategies and curriculum-related understanding. The research also contributes to the development and implementation of methods for promoting a more effective style of teacher-learner interaction in the classroom.  相似文献

Educational researchers have suggested that computer games have a profound influence on students’ motivation, knowledge construction, and learning performance, but little empirical research has targeted preschoolers. Thus, the purpose of the present study was to investigate the effects of implementing a computer game that integrates the prediction-observation-explanation (POE) strategy (White and Gunstone in Probing understanding. Routledge, New York, 1992) on facilitating preschoolers’ acquisition of scientific concepts regarding light and shadow. The children’s alternative conceptions were explored as well. Fifty participants were randomly assigned into either an experimental group that played a computer game integrating the POE model or a control group that played a non-POE computer game. By assessing the students’ conceptual understanding through interviews, this study revealed that the students in the experimental group significantly outperformed their counterparts in the concepts regarding “shadow formation in daylight” and “shadow orientation.” However, children in both groups, after playing the games, still expressed some alternative conceptions such as “Shadows always appear behind a person” and “Shadows should be on the same side as the sun.”  相似文献

In this article, we consider the complex and dynamic inter-relationships between individual science teachers, the social space of their work and their dispositions towards teacher leadership. Research into the representation of school science departments through individual science teachers is scarce. We explore the representations of four individual teachers to the assertions of teacher leadership proposed by Silva et al. (Teach Coll Rec, 102(4):779–804, 2000). These representations, expressed during regular science department meetings, occur in the social space of Bourdieu’s “field” and are a reflection of the “game” of science education being played within the department. This departmentally centred space suggests an important implication when considering the relationship between subject departments and their schools. The development of an individual’s representation of teacher leadership and the wider “field” of science education appears to shape the individual towards promoting their own sense of identity as a teacher of science, rather than as a teacher within a school. Our work suggests that for these individuals, the important “game” is science education, not school improvement. Consequently, the subject department may be a missing link between efforts to improve schools and current organizational practices.  相似文献
