Research And Practice Of Integrating The Idea Of Life Into Chemical Experiment Teaching In Rural Junior Middle School

At present,there is a big gap between rural junior middle school and metropolis junior middle school in terms of teaching staff,teaching resources,teaching concept and learning environment.In order to narrow this gap,the author introduced some life-experienced experimental teaching cases that I had experienced and summed up into the teaching of rural junior middle schools.Through using the common materials to teach,I improved the interest of classroom teaching,and increased the closeness of knowledge.Through allowing students to participating in experiments,students could understand knowledge,learn knowledge,acquire knowledge,and apply knowledge.This article takes the current situation of chemistry experiment in rural junior high school in Linqu County as the research object.I mainly study from four aspects:First of all,after reading a large number of domestic and foreign literatures,I summarized the status and methods of the research on the teaching of life in chemistry experiments.In this paper.I defined the related concepts.I also Introduced the meaning of the Dewey's educational theory,Tao Xingzhi's life education,the constructivism,and the STS in the article.These theories provide a theoretical basis for research.Secondly,I investigated and analyzed the current situation of the chemistry experiment teaching in rural area.I has separately prepared the students' questionnaires and teacher questionnaires about the chemistry experiment teaching in rural junior middle schools.I analyze the current status of the current junior middle school chemistry experiment teaching from various angles through interviewing with some teachers.The student survey shows that students are very interested in chemistry experiments and that chemistry learning should be closely linked to life,but subject to personal time,life experience,pressure in the examination,lack of theory and knowledge,etc.,the degree of attention to life phenomena and social issues is low.The ability to solve practical problems is weak.The teacher survey questionnaire shows that when teachers are teaching,they can guarantee the opening rate of demonstration experiments and grouped experiments.Most teachers agree that experimental teaching and life philosophy are integrated,but due to heavy tasks and class pressure Large-scale,lack of flexibility in teaching and other reasons,there are generally less demonstration of complex experiments,experimental innovation,less improvement,less introduction of extra-curricular life experimental cases,lack of development of experimental life-based teaching skills.Thirdly,according to the results of the survey questionnaire,I proposed five basic principles and implementation strategies for life-oriented chemistry experiments.The five basic principles for the analysis of practical cases are: living principle,subjective principle,practical principle,science Principle and safety Principle.In terms of implementation strategy,I believe that the introduction of life-oriented teaching cases in classrooms and experimental classes is very necessary for mobilizing students' curiosity,keeping them interested in chemistry,and learning in happiness.I also studied and explored the teaching cases of “Molecule”,“Guardian of delicious pastries” and extracurricular extension practice cases “Exploration: Factors affecting the speed of salt dissolving in water” and “Exploration experiments of gas components in fish gills”.Finally,I implemented the design practice teaching cases in two classes and compared the result.The results show that the experimental class is better than the normal class regardless of interest in learning,learning attitude or learning ability.Comparing the results of the final exams of the two classes,it is found that the average score of the control class is not only low,but also the number of low-segmented students,which fully shows that the life-oriented teaching is a good teaching method for the rural junior middle school.
