中学化学实验教学中生活化的研究

摘要新课程标准指出，化学教学要从学生已有的生活经验出发，让学生在熟悉的生活情景中感受化学的重要性。社会的高速发展也要求学生把所学习的知识应用于生活实际，而实验是高中化学学习中非常重要的一项内容，因此有效实施生活化实验有着非常重要的现实意义。本文首先分析了国内外化学生活化实验的研究现状，通过问卷调查了学生在做实验过程中的兴趣、状态以及期望等方面的情况，了解到目前的高中化学实验教学脱离了学生的生活经验，导致学生学习化学的兴趣下降，同时也导致了学生联系化学与生活的意识薄弱。为了使生活化实验教学从单一的教学形式到多元化教学形式，本文基于生活化实验的现状提出生活化实验应用的有效途径，然后结合理论基础和生活化实验设计原则设计了生活化实验，铜氨纤维的制备-在课外活动中的应用。通过实践研究，本文得出了以下结论：(1)生活化实验贴近生活，与学生们的生活息息相关，使学生对化学实验更感兴趣：(2)生活化实验使得学生认识到化学与生活密不可分的关系，对学生后续的化学学习有积极影响：(3)生活化实验的设计不仅更安全、环保，而且提高了学生的参与度，开拓了学生的思维，培养了学生的综合素质：(4)不同形式的生活化实验丰富了高中化学教学，让更多的生活化实验可以被教师实际应用于化学教学中，使得生活化实验真正成为高中化学教学的有效补充。关键词：生活化实验：高中教学：应用研究AbstractThe new curriculum standards point out that chemistry teaching should start fromstudents'existing life experiences,allowing them to feel the importance of chemistry infamiliar life situations.The rapid development of society also requires students to apply theknowledge they have learned to practical life,and experiments are a very important part ofhigh school chemistry learning.Therefore,effective implementation of life orientedexperiments has very important practical significance.This article first analyzes the currentresearch status of chemical life experiments both domestically and internationally.Througha questionnaire survey,students'interests,states,and expectations during the experimentalprocess were investigated.It was found that the current high school chemical experimentteaching is detached from students'life experiences,leading to a decrease in students'interest in learning chemistry and a weak awareness of connecting chemistry with life.Inorder to transform the life oriented experimental teaching from a single teaching form to adiversified teaching form,this article proposes effective ways to apply life orientedexperiments based on the current situation of life oriented experiments.Then,combiningthe theoretical foundation and design principles of life oriented experiments,the preparationof copper ammonia fiber and its application in extracurricular activities are designed;Through practical research,this article draws the following conclusions:(1)Lifeoriented experiments are close to life and closely related to students'lives,making themmore interested in chemical experiments;(2)Life oriented experiments make studentsrealize the inseparable relationship between chemistry and life,which has a positive impacton their subsequent chemistry learning;(3)The design of life oriented experiments is notonly safer and more environmentally friendly,but also enhances students'participation,expands their thinking,and cultivates their comprehensive qualities;(4)Different forms oflife oriented experiments have enriched high school chemistry teaching,allowing more lifeoriented experiments to be applied by teachers in chemistry teaching,making life orientedexperiments truly an effective supplement to high school chemistry teaching.Keywords:Lifestyle experiments;High school teaching;application research目录摘要。。。Abstract第1章绪论…1.1选题依据....1.1.1落实新课程标准的要求.11.2国内外研究现状11.2.1国外研究现状…。.21.2.2
