Application And Practice Research Of Micro Chemistry Experiment In Inquiry Teaching

With the new curriculum reform deeply and widely promotion,the chemical experiment in training students’ ability of function,gradually become a focus of attention of teachers and teaching in order to satisfy the study way subjectification and the characteristics of the course content into daily life,constantly requirements of chemical experiment to advance towards,green life and explore and develop.In order to comply with the curriculum reform requirement,this paper combines the miniature chemical experiments with the exploring teaching,chemistry textbooks for high schools to miniaturization design and improvement,part of the experiment,two typical experimental inquiry teaching in teaching practice,finally to the students in the aspects of knowledge,skill,emotion to improve and change,the use of a variety of ways to make a reasonable analysis and evaluation,which explains the research for students to master knowledge,exploring ability,the cultivation of innovative consciousness of teaching effect.In order to provide reference for the combination teaching of micro chemistry experiment and inquiry.This paper is divided into five parts,the main contents are as follows:Part Ⅰ:research overview.Based on the needs of the development of curriculum reform,students’comprehensive and the high school chemistry experiment teaching present situation as the research background,through literature,an overview of the research significance,research methods,to determine the content and way of thinking about micro experiments and inquiry teaching at home and abroad,review the research status,found that at present the research for the combination is less.Part Ⅱ:concept definition and theoretical basis.This part mainly is to distinguish the concept of micro experiments with exploring and defined,based on the research content involves the education theory of learning and classification,under the guidance of relevant theoretical basis for research,Systematically expound the design of the micro chemical experiment and improvement,and exploratory teaching combined with the application design must follow the principle of scientific,innovative,security,students’ subjectivity.Part Ⅲ:Salt pond in ningxia some middle school teachers and students as the research object of questionnaire survey,based on data analysis,school resources,information on the development of high school chemistry experiment teaching,students’ attitude to chemistry experiment,etc.,through the elaboration of miniature experiments and exploring the teaching characteristics,analysis the advantage of the combination,to effectively resolve the shortage of teaching resources and teaching form a single,students’ classroom learning efficiency low countermeasures are put forward.Part Ⅳ:Design and practice of micro experiments and teaching cases.Miniaturized the design and improvement of some experiments in the high school chemistry textbook of the People’s Education Board,and selected "Preparation and Properties of Chlorine" and "Properties of Nitric Acid" as the teaching content,and found learning,constructivist learning,and inquiry learning in Bruner.Under the guidance of theory,the general mode of inquiry-based teaching is used to design teaching activities,the designed teaching cases are applied to teaching practice,and after-class knowledge testing,questionnaires,teacher feedback and other methods are used to evaluate the effect of classroom implementation.The data show that the experimental class The students’ mastery of relevant knowledge is obviously stronger than that of the control class,and they express their interest in experimental innovation.A series of feedbacks test the feasibility of applying micro-experiments to inquiry teaching.Part Ⅴ:Research conclusions and prospects.According to the effect of the fourth part of teaching practice effect evaluation,the research results are sorted out and the research conclusions are drawn.Combining micro-chemical experiment and inquiry-based teaching can analyze the existing problems of the experiment and improve the ability of teachers and students;realize the main position of students and change the way of learning;fully embody the concept of "green chemistry" and cultivate scientific inquiry and innovation awareness Attitude and social responsibility;effectively implement the connection between chemistry teaching and society,life and science and technology,and infiltrate STS ideas.Finally,it reflects on the shortcomings in the research process,and looks forward to the different research directions in the combination of micro-chemistry experiments and inquiry teaching.
