Forum: dialogue about dialogue—cogeneration, research and science education

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.     

Trust in testimony: how children learn about science and religion

Many adult beliefs are based on the testimony provided by other people rather than on firsthand observation. Children also learn from other people's testimony. For example, they learn that mental processes depend on the brain, that the earth is spherical, and that hidden bodily organs constrain life and death. Such learning might indicate that other people's testimony simply amplifies children's access to empirical data. However, children's understanding of God's special powers and the afterlife shows that their acceptance of others' testimony extends beyond the empirical domain. Thus, children appear to conceptualize unobservable scientific and religious entities similarly. Nevertheless, some children distinguish between the 2 domains, arguably because a different pattern of discourse surrounds scientific as compared to religious entities.     

Vicarious learning from dialogue and discourse

This study examined learning in the domain of sentence parsing and syntax treediagram construction. The aim of the study was to assess whether subjects could learn vicariously from recordings of interactions between a previous student and a tutor.Four intervention conditions and a control condition were compared. Subjects in a dialogue group (DL) read printed tutorial notes and subsequently vicariously viewed dynamic (animated) recordings of tree diagrams being constructed by a previous student in the presence of a tutor.The discourse (DI) condition was similar except that subjects viewed recordings of tree diagrams being constructed by a tutor who concurrently verbalised instructional discourse.In a third condition (DO), subjects viewed tree-diagram construction animation clips which were not annotated with either dialogue or discourse. In a linear text (LT) condition, subjects were given only printed tutorial notes. A control (CO) condition involved pre and post testing without any intervention.Results indicated that the dialogue condition was as effective as the discourse condition. This provides support for contention that re-usable dialogue is a useful resource for the vicarious learner. Another finding was that un-annotated animated diagrams were surprisingly effective. Several reasons for their effectiveness are suggested from the literature on instructional animations.     

Classroom dialogue and science achievement

Conclusion This study indicates the responsibility that rests with the teacher in an activity-oriented classroom as far as providing the structural support necessary for effective learning (Note 4). The teacher is acting as a “surrogate textbook”. Using their own organization of knowledge-albiet wrong or incomplete-teachers provide the structure that is lacking. As the results indicate, some teachers can do this better than others. A challenge for teachers and teacher educators is to devise ways to improving the structure and sequencing of classroom dialogue. The TSA Technique could help here in two ways. It allows a sophisticated analysis of dialogue, indicating specific areas of weakness which could then be remedied by appropriate training. A similar approach has been used successfully with text material to rewrite and restructure deficient segments (Clarke; 1973). It could also be used to produce ideal “templates” of various models of teaching (e.g. Brady; 1985) for use as a guide for lesson planning.     

Science and religion: implications for science educators

A religious perspective on life shapes how and what those with such a perspective learn in science; for some students a religious perspective can hinder learning in science. For such reasons Staver’s article is to be welcomed as it proposes a new way of resolving the widely perceived discord between science and religion. Staver notes that Western thinking has traditionally postulated the existence and comprehensibility of a world that is external to and independent of human consciousness. This has led to a conception of truth, truth as correspondence, in which our knowledge corresponds to the facts in this external world. Staver rejects such a conception, preferring the conception of truth as coherence in which the links are between and among independent knowledge claims themselves rather than between a knowledge claim and reality. Staver then proposes constructivism as a vehicle potentially capable of resolving the tension between religion and science. My contention is that the resolution between science and religion that Staver proposes comes at too great a cost—both to science and to religion. Instead I defend a different version of constructivism where humans are seen as capable of generating models of reality that do provide richer and more meaningful understandings of reality, over time and with respect both to science and to religion. I argue that scientific knowledge is a subset of religious knowledge and explore the implications of this for science education in general and when teaching about evolution in particular.     

On relations between science and religion

This article proposes an alternative way of looking at religion to that proposed by Mahner and Bunge, and challenges a claim they make about a presupposition of science. From the alternative perspective there are constructive tensions rather than incompatibilities between science and religion. The article concludes with a proposed set of criteria to be used in critical reflections on faiths, religious or secular. It suggests that education would be enhanced by introducing students to the reflections and dialogues where these criteria are applicable.     

恩格斯和列宁的时空观

“一切存在的基本形式是时间和空间”,这是恩格斯提出的科学的对时间空间和物质关系的认识。恩格斯在《反杜林论》、列宁在《唯物主义和经验批判主义》中分别对如何认识时间、空间做了一定的论述,他们在批判了形而上学的时空观的同时,确立了唯物辩证的时空观,为马克思的社会时空观奠定了基础,也是我们客观地认识时间、空间的基础。     

Preservice teacher inquiry: Creating a space to dialogue about becoming a social justice educator

In this paper, we reflect on our experience with an experimental inquiry component within a teacher education program in a large urban city on the West Coast of the United States. This learning space, which is referred to as “Inquiry,” promotes the integration of theoretical and practical knowledge through reflection and dialogue. We highlight how this inquiry-oriented process enabled preservice teachers to reflect on and dialogue about existing ideals of social justice and equity with regard to teaching diverse learners. This process acknowledges that alternative learning spaces in teacher education programs that address ways of observing, questioning, and inventing may well be a valuable strategy in the development of social justice educators. While the process is a valuable one, we offer a critical analysis of our own processes. In particular, we discuss the need for the creation and implementation of strategies that help pre-service teachers build their capacity to teach in diverse urban classrooms.

Discursive geographies in science: space, identity, and scientific discourse among indigenous women in higher education

Despite completing undergraduate degrees in the life sciences, few Indigenous women choose to pursue careers in scientific research. To help us understand how American Indian students engage with science, this ethnographic research describes (1) how four Navajo women identified with science, and (2) the narratives they offered when we discussed their experiences with scientific discourse. Using intensive case studies to describe the experiences of these women, my research focused on their final year of undergraduate study in the life sciences at a university in southwestern US. I point to the processes by which the participants align themselves with ideas, practices, groups, or people in science. As each participant recounted her experiences with scientific discourse, they recreated for me a discursive geography of their lives on the reservation, at home, at community colleges (in some cases), and on the university campus. In the construction and analysis of the narratives for this research, mapping this geography was critical to understanding each participant’s discursive relationship with science. In these discursive spaces, I observed productive “locations of possibility” in which students and their instructors: valued connected knowing; acknowledged each other’s history, culture, and knowledge; began to speak to each other subject-to-subject; and challenged normative views of schooling. I argue that this space, as a location of possibility, has the power to transform the crushing impersonalized schooling that often characterizes “rigorous” scientific programs in a research institution.

Hybrid discourse practice and science learning

In this article, we report on a study of how creative linguistic practices (which we call hybrid discourse practices) were enacted by students in a fifth-grade science unit on barn owls and how these practices helped to produce a synergistic micro-community of scientific practice in the classroom that constituted a fertile space for students (and the teacher) to construct emergent but increasingly legitimate and dynamic disciplinary knowledges and identities. Our findings are important for the ways in which they demonstrate (a) how students use hybrid discourse practices to self-scaffold their work within complex curricular tasks and when they are not completely sure about how to enact these tasks (b) how hybrid discourse practices can promote inquiry orientations to science, (c) how hybrid discourse practices index new and powerful forms of science pedagogy, and (d) how hybrid discourse practices are relevant to more global issues such as the crucial roles of language fluency and creativity, which are known prerequisites for advanced science learning and which aid students in developing skills that are necessary for entry into science and technology careers.     

教育学还在与心理学对话吗?--教育理论研究中教育学和心理学关系的再寻找

教育学自诞生以来就与心理学融合在一起,但随着教育理论研究的多元化倾向,教育学与心理学越来越趋向于分离,以至于筑起人为的藩篱,貌合神离的离异的危机使教育理论研究处于一种无根的状态,必然导致教育理论的虚假繁荣。为此,在教育理论研究中,教育学要主动与心理学沟通、对话、理解。     

科学与宗教错综复杂的关系

西方的科学与宗教的关系并不仅仅是冲突对立,而是错中复杂的。宗教为科学提供驱动力,同时亦给科学铺设障碍。冲突虽有,可是渐渐地宗教会妥协和接近科学的新思想。要区分好科学与宗教的不同,我们要用积极、发展、宽容的态度去看待两者的矛盾冲突。     

Public dialogue with science and development for teachers of STEM: linking public dialogue with pedagogic praxis

Abstract

Despite evidence of quality teaching in Science, Technology, Engineering and Mathematics (STEM) subject domains and insistence on the part of many national governments on the economic value of STEM, education, recruitment and retention into STEM subject fields and occupations is said to be continually blighted by a ‘leaky pipeline’. In the UK context, schools are seen to benefit from a multitude of external STEM engagement and enrichment providers and initiatives. However, despite evidence of the positive impacts of STEM engagement on learners, there exists a dearth of understanding related to how principles of STEM engagement can facilitate STEM teachers in becoming more pedagogically innovative and relevant and, therefore, engaging of their learners in the classroom context. In this article, we employ a secondary data analysis of two prominent cases of public engagement in science and technology (PEST) in the UK to elicit combined lessons for STEM engagement and the pedagogical development of teachers. We consider the successes of science dialogue in establishing principles of best practice that might be transposed to the development of teachers as more able and effective in the engagement of learners in STEM.     

Applying scientific openmindedness to religion and science education

Mahner's and Bunge's two main theses are nearly correct as social reports but the extent to which they are wrong is philosophically very important. I draw attention to a philosophically superior way of viewing the essential relation between science and religion which can have a humane or benign influence upon how both science and religion are taught. On the one hand, science does not need to fight religion nor try to suppress it. A generous openness of mind, which distinguishes the critical rationality implicit in the advance of science, deserves to be applied without acrimony to any systems of thought that purport to explain the universe. On the other hand, religions have no need to fear the growth of scientific knowledge, provided science is not confused, as Mahner and Bunge confuse it, with its materialistic interpretation.     

Pedagogic discourse and sex education: myths,science and subversion

This paper elaborates possibilities and limitations for sex education in schools by mapping the consequence of introducing the topic ‘sex’ within a range of scientific and informal discursive settings. The organising and regulating structures of the school maintain the boundaries between common‐sense and scientific discourses. Bernstein made a distinction between vertical discourse and horizontal discourses. Vertical discourses characterise scientific discourses that are coherent, explicit and systematically principled structures. Horizontal discourses characterise common‐sense discourses that are local, segmented and context‐dependent. The implications for teaching sex education through vertical discourses such as science, English and art as opposed to personal and social education, which is a horizontal discourse, are discussed. Yet, all discourses are unstable, and the notion of a ‘tipping point’ is introduced to demonstrate the potential for sex education when vertical discourses collapse.     

关于标志设计的时间与空间问题略析

标志设计与时间有关,它是有生命的。随着社会发展、科技进步,它也应随之发展变化,以适应新的时代。标志设计又是与空间有关的。一个标志的设计往往在某种程度上能起到扩展或限制其使用范围的作用,尤其是现今的中国企业和产品势必要参与国际市场的竞争的情况下,标志设计显得更为重要。     

Rethinking science literacy: Enhancing communication and participation in school science through affirmational dialogue journal writing

For many students the study of science can be very disaffirming. This may lead to passivity in class and a lifelong disaffection with science, outcomes which defeat the long‐term purpose of trying to achieve scientific literacy for all students. This article represents a new way of framing scientific literacy with a “science for all” goal, based on a nexus of psychological, sociological, and critical literacy theory. A science education researcher and a science teacher collaborated in trialing the use of affirmational dialogue journal writing with early adolescents in a high school situated in a low socioeconomic status area. The intervention was found to be successful on a number of fronts. An approach which affirms students' experience can lead to a deeper approach to learning for adolescent science students. © 1999 John Wiley & Sons, Inc. J Res Sci Teach 36: 699–717, 1999
