【摘要】 新课程改革强调以学生为本,教学设计应以学生为中心,培养学生终身学习的愿望。新的化学课程标准注重激发学生的主动性和创新性,激发学生主动学习,使获得化学知识和技能的过程成为理解化学、进行科学探究、联系社会生活、形成科学价值观的过程。作者所在学校积极推进教学改革。在过去的两年中,“双学讲”教学模式已经引入课堂教学,包括化学教学。“双学讲”教学模式以学生的认知特点为基础,对教学内容进行两次学习和讲解,两次学习和讲解并不是机械的进行两次,而是学生学习过程的升华,循序渐进,让学习知识达到质的飞跃,符合素质教育的要求,可以调动学生对化学的兴趣,实现课堂教学的实效性,不断提高化学课堂教学的效果,提高初中化学整体教学的质量。与传统的教学模式相比,“双学讲”教学模式更注重学生的学习主动性和学习积极性,努力培养学生自主获取知识和技能。本文通过对作者所在单位的“双学讲”的教学模式作为基础,对化学课程进行实践探索,综合采用了多种研究方法包括文献法、问卷调查法、实证分析法、访谈法,实验法等,对实践结果进行分析,调查和反馈,探讨初中化学“双学讲”教学模式的应用效果。通过研究,得出的结论如下:初中化学“双学讲”教学模式应用存在在处理接受学习与探索学习方式关系上不恰当,信息技术观念错误,缺乏正确合理的评价的问题。面对这些问题,应该采用注重学生素养建立,教育思想和观念的转变,改进对信息化认识的转变和开展教师交流活动等策略进行应对。经过实践研究,认为“双学讲”教学模式在化学教学中是可行的,在提高学生自主学习能力,促进学生学习方式转变方面具有很大的优势。但同时,这种教学模式也有一定的局限性。作者对如何改进提出了一些看法,希望能为化学教学提供一些有意义的参考,也为其他人深入研究这一课题提供一些依据。更多还原

【Abstract】 The new curriculum reform emphasizes student-oriented,and the teaching design should be student-centered and cultivate students’ desire for lifelong learning.The new chemistry curriculum standards focus on stimulating students’ initiative and innovative consciousness,promoting students to study actively,and making the process of acquiring chemical knowledge and skills become the process of understanding chemistry,conducting scientific inquiry,linking social reality and forming scientific values.The author’s school actively promotes teaching reform.In the past two years,the “double learning and lecturing” teaching model has been introduced into classroom teaching,including chemistry teaching.Based on the cognitive characteristics of students,the teaching mode of "double learning and lecturing" carries out two studies and explanations of the teaching contents.The two studies and explanations are not two mechanical ones,but the sublimation of the students learning process,step by step,so that the learning knowledge can reach a qualitative leap and meet the requirements of quality education,which can arouse students’ interest in chemistry and realize the effectiveness of classroom teaching.Continuously improve the effect of chemistry classroom teaching,to achieve the improvement of the overall quality of Chemistry Teaching in junior high school.Compared with the traditional teaching mode,the “double learning and lecturing” teaching mode pays more attention to students’ learning initiative and learning enthusiasm,and strives to cultivate students to acquire knowledge and skills independently.Based on the "double learning and lecturing" teaching model of the author’s unit,this paper explores the practice of chemistry curriculum,and comprehensively uses a variety of research methods,including literature,questionnaire,empirical analysis,interviews and experimental methods,to analyze the practical results,investigate and feedback,and explore the application effect of the "double learning and lecturing" teaching model in junior high school chemistry.Through the research,the conclusions are as follows: The application of the teaching mode of junior high school chemistry double teaching has the problem of dealing with the relationship between the acceptance learning and the exploration learning mode,the information technology concept is wrong,and the correct and reasonable evaluation is lacking.Faced with these problems,we should adopt a strategy that focuses on the establishment of student literacy,the transformation of educational ideas and concepts,and the improvement of the understanding of informatization and the development of teacher exchange activities.After practical research,the author believes that the "double learning and lecturing" teaching mode is feasible in chemistry teaching,and it has great advantages in improving students’ independent learning and promoting the change of students’ learning style.But at the same time,this teaching mode also has certain limitations.The author puts forward some opinions on how to improve and improve,and hopes to provide some meaningful reference for chemistry teaching,and also provide some evidence for others to conduct in-depth research on this topic.更多还原
