【摘要】 在科学教育中运用论证的方式来开展教与学的活动是当前国际科学教育研究的热点问题。当今世界,科学教育正在从以往的“获取答案”、“视科学为探索和实验”、“提供有关科学内容之问题的答案”、以及“以实验结果作为探究最后的结论”转向强调“使用证据和策略来发展或修正解释”、“视科学为论证和解释”、“沟通科学解释”,以及“应用实验的结果到科学的论证和解释”,以培养有科学素养的公民。正是在这样的趋势和背景中,本研究对科学教育中的论证教学展开了理论和实践的探索。研究聚焦的核心问题是“什么是科学论证教学,它在实践中的境遇如何?”为此,研究中运用文献分析法、案例研究法、访谈法、诠释法以及比较分析的方法对科学论证教学的理论和实践层面展开了探索,获得的研究成果包括以下五个方面。第一,辨析了科学教育中论证和论证教学的概念,阐明了科学论证教学与科学探究教学的关系,厘清了科学论证教学研究的发展脉络与现状。科学论证教学与科学探究教学在本质上是契合的,前者是对后者的一种丰富和发展。科学论证教学更加强调儿童在科学学习中对“证据的形成和使用”,对学习过程和学习结果的“沟通和解释”以及对“知识的产生”和“知识的评价”两个方面的认识、体验和实践。科学论证教学研究起始于20世纪80年代,在90年代中期美国《国家科学教育标准》颁布后逐渐受到重视和强调,当前的研究主要集中在四个方面,包括关于学生论证的过程中论点和论证品质的分析方法和分析框架,评价学生的论证能力；开发论证活动的教学材料和教学策略支持论证教学；科学课堂中师生互动的话语分析以及计算机支持的论证学习活动的设计与开发。第二,阐释了论证在科学教学中的意蕴。首先从论证涉及的潜在思考知能出发,分析了论证在科学教学中的功能,通过对论证与科学素养的关系的探讨和科学课程标准及课程中包含的论证的内容,展现论证在科学教学中的重要地位。然后结合科学教学的内容分析了多种论证的结构与模式,以进一步呈现和阐述科学教学中论证的过程与内涵,并梳理了当前科学论证教学研究中对论证品质的评量方式。第三,分析了科学论证教学中论证学习活动的本质。论证学习活动是一种推理的过程(个人层面的论证),是一种关于科学的对话过程(人际间的论证),是一种批判性思考的过程(论证的核心),这三个方面相互交织又各有侧重。理解论证学习活动的本质能够帮助教师把握论证教学的设计和发展方向,最大潜能地发挥论证教学的优势。第四,探讨了科学论证教学在科学教育中的应用。在分析科学论证教学的六大维度的基础上,探索了在科学教育中适合采用论证的教学方式来开展学习活动的两类题材,即科学概念的学习和社会性科学议题的学习。在这两个题材领域,论证教学过程中所使用的具体的教学策略和运用的方式是有区别的。科学论证教学特别强调需要创建一种安全而富有质询精神的学习共同体环境,研究以安全感、真实参与性、挑战性问题、主导权问题为四个支点,建构了辅导者在科学教学中创建学习共同体的决策模型。最后,以社会性科学议题为例,对科学论证教学展开了实践研究。研究中以七年级泥石流教学中“土地开发与资源保护”的争议性议题为例,对中美两位教师的论证教学和两个班级的论证学习活动进行了详细描述与分析。此项实践研究获得的研究结论包括：两位教师在实际教学中运用的教学策略比预设的教学策略都有不同程度的丰富和拓展,教师的教学理念对教学过程的发展和学生的学习过程产生影响；两个班级的对话论证活动在举证支持、反驳与质疑、教师引导运用证据和材料、教师帮助化解反驳与质疑、对话论证受学生原有知识水平的影响五个方面表现出共通性,而在学生的参与性、论证话题的跳跃性、证据的来源以及论证发展的程度方面表现出差异性；通过对学生论证学习活动反思的访谈分析发现,E班学生认为证据是对话论证学习活动的核心,T班学生认为发言是对话论证活动的核心,他们在资料的搜集与整理方面都遇到困难,他们共同认为论证活动能够激发多元的思考,但是需要完成很多的学习任务,化费较多的时间；通过对两位教师教学反思的访谈分析发现,E老师认为论证教学的核心是证据的形成与使用,T老师认为论证教学的核心是学生发言,两位老师都认为自己在论证教学的过程中将更多的注意力放在论证活动的发展。研究表明,论证在科学教育中是一种有效的教与学的方式和策略,对发展学生的高级思维能力、理解科学的本质、提高学生的科学素养具有独特的作用。希冀我国的科学教育工作者对此引起关注、研究,将科学论证教学更广泛地应用于科学教学实践,以改进我国传统的科学课堂教学。更多还原

【Abstract】 Using argumentation for teaching and learning science is a hot research question in current international science education research field. Instead of "Getting an answer","Science as exploration and experiment","Providing answers to questions about science content" and "Concluding inquiries with the result of the experiment", current science education is turning to "Using evidence and strategies for developing or revising an explanation","Science as argument and explanation","Communicating science explanations" and "Applying the results of experiments to scientific arguments and explanations" for scientifically literate citizens. Underlying in this trending and background, this study explored the theory and practice of argumentation-oriented science instruction in science education.This study focused on the core question of "what is the argumentation-oriented science instruction, and how it is developed in the teaching and learning practice?" To answer the research question, the study employed several research methodologies including literature research, case study, interview, descriptive research and comparative analysis to explore the theory and practice of argumentation-oriented science instruction, and achieved the following research results.First, the study defined the conception of argumentation and argumentation-oriented science instruction, stated the relationship between argumentation-oriented science instruction and inquiry-based science instruction, and clarified the historical development and present situation of researches on argumentation-oriented science instruction. Argumentation-oriented science instruction is concordant with inquiry-based science instruction, with enriching and developing inquiry-based science instruction. However, the former stresses more on the development and application of evidence, the communication and explanation for the learning process and learning outcomes,the epistemology, experiences as well as practices on "the production of knowledge" and "the assessment of knowledge". Researches on argumentation-oriented science instruction started in1980s, and gradually got recognized and emphasized after the publication of National Science Education standards in1996. The current researches are mainly on four aspects including researches on developing analytical methods and frameworks for students’argumentations and assessing the students’argumentative ability, researches on developing right materials and instructional strategies for supporting argumentation-oriented science instruction, researches on the discourses analysis of interactions underlying argumentation-oriented science instruction as well as researches on the designing and development of computer-supported argumentation-oriented science instruction. Second, the study explained the implications of argumentation in science instruction. Based on the potential contributions from argumentation, the functions of argumentation in science instruction were analyzed. The importance of argumentation in science instruction was demonstrated via the discussion of argumentation and scientific literacy, and the exhibition of argumentative content in science curriculum standards as well as science curriculums. Then, different structures and patterns of argumentation were analyzed with integrating the content of science instruction to further explain the process and meaning of argumentation in science instruction. The assessments of the quality of argumentation were also analyzed from the current researches on argumentation-oriented science instruction.Third, the study elaborated nature of argumentation-oriented science learning. It has three aspects, which are a process of reasoning (intrapsychological argumentation), a process of producing dialogues (interpsychological argumentation), and a process of critical thinking (core of argumentation). These three aspects are interlaced with each other while each of them has its own focus. Understanding the nature of argumentation-oriented science learning could help teachers do argumentation-oriented science teaching better.Forth, the study explored the application of argumentation-oriented science instruction. Based on the analyzing of six dimensions, it was stated that argumentation-oriented science instruction is appropriate for two different science learning areas which are scientific conception learning and socio-scientific issues. The concrete instructional strategies in these two areas are different. It was stressed that applying argumentation-oriented science instruction should be in a learning community full with safety and inquiry. The study took safety, authentic participation, challenge and ownership as four fulcrums to create a learning community and constructed a decision-making model for teaching argumentation.The last, the study did a practical research of argumentation-oriented science instruction using a case study. It explored two teachers using argumentation-oriented science instruction for teaching a socio-scientific issue of "land development and environmental protection" and got four research conclusions:(a) The applied instructional strategies of argumentation-oriented science instruction got enriched and developed in the teaching process comparing with the designed instructional strategies, and teachers’ teaching philosophy effected the development of instruction and the outcome of students’ learning;(b) Conducting analysis on the discourse of interactions for the two classes and found they had intercommunity and differences. The intercommunity is on evidence supporting, rebuttal and inquiry, teacher guiding data and evidence using, teacher helping solve rebuttal and inquiry, and students’ prior knowledge influencing the development of argumentation. The differences are on student’s participation, Off-Topic Conversation, sources of evidences and the developmental degree of argumentation.(c) Conducting analysis on students’ reflections on argumentative activities and found the E class took evidence as the core of argumentative activity while the T class took speaking as the core of it. Both of the classes encountered difficulties on data searching and organizing. Both of the classes realized that argumentative activity could promote multiple thinking but it required huge work and much time,(d) Conducting analysis on the two teachers’ reflections on argumentative activities and found teacher E took the development of evidence as the core of argumentation activity while teacher T took students can make speaking as the core of it. Both of the two teachers found they paid more attention on the development of argumentation than on individual student learning.The study fully demonstrated that argumentation is an effective way and strategy for teaching and learning science. It has distinguished contributions on developing students’ high-order thinking, getting understanding of nature of science and improving scientific literacy. More researches and practices of argumentation-oriented science instruction are expected to improve traditional science instruction in our country.更多还原
