【摘要】：小学科学对比实验作为小学科学实验教学中的重要内容,在实验教学中占据了很重的分量,对提高学生的科学素养起到了重要的作用,也引起了广大科学教师的高度关注。本文查阅并分类整理了对比实验的研究现状,分析了小学科学对比实验教学现状,并在此基础上,针对小学科学对比实验教学的一些具体问题,如识别变量不充分、变量和不变量控制不到位、实验设计方案与操作不一致、证据收集和处理方式不严谨、结论缺乏说服力等,进行了剖析与解决方案论证。本文以《简易温度计》一课为研究案例,立足课堂教学,运用凯米斯的四环节研究法,进行了三轮螺旋式递进的对比实验教学设计的实践研究。通过对观察、访谈、干预实验等方法收集的相关资料的研究分析,对比了三轮教学设计和实施情况,并详细分析了最后一轮教学实录的实践效果。论文针对收集整理教学实践中的真问题,呈现了小学科学对比实验教学设计实践中循环递进的优化对比实验教学设计,提高教学效果的改进过程,教师在此过程中提升了对比实验教学的指导水平,积累了更丰富的教学设计实践的经验。逐层递进的教学设计模式切实促进了学生在对比实验中实验设计、操作、观察、分析等综合探究能力的形成,提升了学生的科学素养,使小学科学对比实验的教与学更具针对性、操作性和实效性。通过一线教师在教学设计实施过程中的经验总结与反思,完善了教学实践及理论,同时也为教学的一线教师提供研究的理论和实践启示,为教师的教学提供最直接、可操作性的参考,最终促进教师的教学方式和学生学习方式的转变。
[Abstract]:As an important part of primary school science experiment teaching, primary science contrast experiment plays an important role in improving the students' scientific literacy, and it also attracts the attention of the majority of science teachers. This paper reviews and classifies the current research situation of comparative experiment, analyzes the present situation of science contrast experiment teaching in primary school, and on this basis, aiming at some specific problems of science contrast experiment teaching in primary school, such as insufficient identification variables, The control of variables and invariants is not in place, the experimental design is inconsistent with operation, the collection and handling of evidence is not rigorous, and the conclusions are not convincing. Taking the lesson of simple thermometer as a case study, based on classroom teaching and using Kemis' four-link research method, this paper has carried out three rounds of spiral comparative experimental teaching design practice research. Through the research and analysis of the data collected by the methods of observation, interview and intervention experiment, this paper compares the design and implementation of three rounds of teaching, and analyzes in detail the practical effect of the last round of teaching record. Aiming at collecting and sorting out the real problems in teaching practice, the paper presents the process of improving the teaching effect by optimizing the teaching design of contrast experiment in the practice of scientific contrast experiment teaching in primary school, and improving the teaching effect. In this process, teachers improve the guiding level of comparative experiment teaching and accumulate more experience in teaching design practice. The progressive teaching design model promotes the formation of students' comprehensive abilities in experimental design, operation, observation, analysis and so on, and improves the students' scientific literacy. Make primary school science contrast experiment teaching and learning more pertinence, maneuverability and actual effect. Through summing up and reflecting on the experience of the first-line teachers in the process of implementing the teaching design, it improves the teaching practice and theory, at the same time, it also provides the theoretical and practical enlightenment of the research for the first-line teachers, and provides the most direct teaching for the teachers. The operable reference will ultimately promote the transformation of teachers' teaching methods and students' learning styles.
