Research On The Design Strategy Of Exploratory Experiment In High School Chemistry

Chemistry is a based on the experiment of natural science,the chemical experiment in middle school chemistry teaching occupies an extremely important position,throughout the chemistry teaching of chemistry experiment,the chemical experiment teaching quality directly affect the overall development of students,the department of education awarded the 2017 edition of ordinary high school chemistry curriculum standard requires all teaching activities to the development of students as fundamental purpose,advocated by a variety of inquiry activity of chemical experiment is given priority to,make students experience the process of scientific inquiry,arouse students’interest in learning,emphasizes to explore the cultivation of the consciousness,change the way of promoting students’learning,improve the students’practical ability in the hands-on practice It can be seen from this that exploratory chemistry experiment teaching is particularly important in middle school chemistry education.With constantly promoting education reform,the teaching means and methods have been improved but in terms of the exploratory experiment teaching,and is still under operating conditions in different areas of the scheduling,teachers teaching method theoretical teaching and experimental teaching link owes fully and the pressure from the university entrance exam course influence still exists and uneven chemical experiment teaching,mainly teachers demonstration experiment;Student experiments are mainly confirmatory;Even there is given priority to with video playback experiments of the experimental teaching way of exploratory experiment teaching in our country,the scope of the implementation is not enough to spread effect is not ideal,to improve the teaching mode and teaching design based on the present situation,this study choose the high school chemistry exploratory experiment teaching design study,adopt the method of literature investigation questionnaire interview survey method,teaching practice,and other research methods,research and analysis on relevant teaching demonstration.The first part of the paper,through a large number of literature analysis,combined with the constructivism theory bruner found learning theory new curriculum standard theory and other relevant theoretical guidance.It also defines the concepts of inquiry learning,inquiry experiment and inquiry teaching.Including the students of Suining Middle School in Sichuan Province,first-line chemistry teachers,school leaders to carry out a questionnaire or interview survey,elaborated the importance of exploratory experimental teaching from many aspects,and conducted relevant research based on the current teaching situation of middle schoolPaper in the second part discusses the influential factors of the implementation of exploring experimental teaching and the design strategy of exploring experimental teaching in combination with the teaching experience and teaching objectives,design closely linked to the five life applicability of exploring high school chemistry experiment,including the preparation and properties of the preparation and properties of Cl₂、SO₂copper with concentrated sulfuric acid reaction of ammonia catalytic oxidation properties of different saline solution,and the design of exploratory experiment to the teaching practice of empirical research on the teaching practice,after collecting the feedback information and data of many sided,through research and analysis,the effective implementation of the exploratory chemical experiment,can improve the students’interest in learning Stimulate students’desire to explore and improve students’academic performance and comprehensive quality,which is conducive to the improvement of teachers’scientific research and teaching skillsFinally in this paper,the design of the high school the exploratory chemical experiment teaching and the practical significance,the design for a line of exploring experimental teaching is the teaching of enlightenment and reflection with constantly deepen education reform,the exploratory experiment teaching design will be more reasonable and perfect,the exploratory experiment teaching in high school chemistry teaching will also be better implement and promote this is also the meaning of this thesis research...
