【摘要】：新课程改革提倡化学教学实行STS教育,强调教师把真实的情境引入课堂,学生能够把所学的化学知识运用到实际生活中去。“燃烧与灭火”这节课的内容体现了STS教育科学、技术和社会的三个方面,是STS教育的良好素材。所以,选取这节课进行基于STS教育的教学设计,期待能为中学化学教师提供教学参考。本文首先说明了STS教育的重要性。在分析了国内外的研究现状和已有教学设计的基础上,以STS教育作为理论基础,然后进行了STS教育的“燃烧与灭火”教学设计,并在初中课堂上实施,目的是提高学生的解决问题能力。论文共包括七个部分,主要内容如下:第一部分,问题的提出,阐明选题的原因。第二部分,综述关于STS的研究以及燃烧与灭火教学研究。分析发现对“燃烧与灭火”进行STS教育教学的可行性和必要性,并从中得到了很多有益的启发。第三部分,明确了研究的目的和任务。第四部分,研究构建了基于STS教育理念的教学设计的策略,包括充分理解STS教育的目标定位、联系STS内容创设学习情境、精心设计情景化的驱动性问题、设计组织多种层次的探究活动,为后续基于STS的“燃烧与灭火”的教学设计奠定了基础。第五部分,进行了基于STS的“燃烧与灭火”的教学设计。在教学内容分析、学情分析基础上,确立了本节课的教学目标,教学过程基于STS教育理念,首先从燃烧反应推送天宫二号升空这一社会焦点引入课题,继而引导学生深入探究学习燃烧的条件和灭火的原理等科学知识,在此基础上,引导学生把燃烧与灭火的科学知识应用于高科技领域,分析宇宙飞船防火设计之谜和火炬不灭设计之谜,从而以燃烧与灭火为主线建立科学、技术、社会之间的有机联系。第六部分,应用本研究设计的基于STS教育理念的“燃烧与灭火”教学设计方案,进行具体的教学实践,用自编课后练习和学生访谈检测学生的学习效果。第七部分,研究结论与展望。总结了本论文的研究结果,并提出了需要进一步解决的问题。
[Abstract]:The new curriculum reform advocates the implementation of STS education in chemistry teaching and emphasizes that teachers can introduce the real situation into the classroom and students can apply what they have learned in real life. The content of the course "Burning and extinguishing" embodies the three aspects of STS education science, technology and society, and is a good material for STS education. Therefore, this course is chosen to be a teaching design based on STS education, which is expected to provide teaching reference for middle school chemistry teachers. This paper first explains the importance of STS education. Based on the analysis of the current research situation and the existing teaching design at home and abroad, this paper takes STS education as the theoretical basis, and then carries out the teaching design of "burning and extinguishing fire" in STS education, and implements it in the middle school classroom. The aim is to improve students' ability to solve problems. The paper consists of seven parts. The main contents are as follows: the first part, the questions raised, the reasons for the topic. In the second part, the research on STS and the teaching of burning and extinguishing are reviewed. This paper finds out the feasibility and necessity of STS education and teaching of "Burning and Fire extinguishing", and gets a lot of useful inspiration from it. The third part clarifies the purpose and task of the research. The fourth part studies the strategies of teaching design based on STS educational concept, including fully understanding the goal orientation of STS education, creating learning situation in connection with the content of STS, and carefully designing the driving problem of situational. The design organization of inquiry activities at various levels lays a foundation for the teaching design of "Burning and extinguishing" based on STS. In the fifth part, the teaching design of "burning and extinguishing" based on STS is carried out. Based on the analysis of teaching content and the analysis of learning situation, the teaching goal of this class is established. The teaching process is based on the STS educational concept. Firstly, the topic is introduced from the social focus of combustion reaction pushing Tiangong 2 into the sky. On the basis of this, the students are guided to apply the scientific knowledge of burning and extinguishing to the field of high technology. This paper analyzes the riddle of fire prevention design of spaceship and the mystery of the design of torch inextinguishment, so as to establish the organic connection among science, technology and society by taking combustion and fire extinguishing as the main line. In the sixth part, the teaching scheme of "burning and extinguishing fire", which is based on the STS educational concept, is applied to the teaching practice, and the students' learning effect is tested with self-compiled exercises and student interviews. The seventh part, research conclusion and prospect. The research results of this paper are summarized and the problems that need to be solved are put forward.
