Research On Improvement And Practice Of Middle School Chemistry Experiment Based On Scientific Inquiry And Innovation Consciousness

With the advancement of education reform in my country,the new curriculum reform based on literacy training has entered the stage of actual combat.The newly revised 2020 edition of "Chemistry Curriculum Standards for General High Schools"pointed out that in order to meet the diversified development needs of students,the setting of chemistry courses should be hierarchical,diversified,and optional;This kind of experimental activities can mobilize the subjective initiative of students,and pay attention to the structured design of teaching content to realize the realization of literacy.Among them,the literacy of "scientific inquiry and innovation consciousness" requires students to be able to discover and raise valuable questions;to design inquiry plans and conduct experimental inquiry based on problems and hypotheses;to be able to exert subjective initiative and be brave in innovation.However,in previous researches,teachers usually improve experiments,and directly replace teaching materials experiments with improved experiments in teaching.Few of them are "student-centered" and give full play to students’ initiative to improve the design and teaching of experiments.In view of this,from the perspective of students,this article aims to "implement the core literacy of"scientific inquiry and innovation consciousness",combines the characteristics of knowledge and students’ learning situation,designs experiments that can be explored and improved by students,and applies them to classroom teaching.The research is as follows:(1)After sorting out and analyzing relevant literature at home and abroad,it was determined that the research idea of this paper was to transform the "teaching-centered" into the "learning-centered" teaching concept,innovatively design middle school experiments and experimental teaching,and transform and improve the teaching concept;(2)Carry out investigations on the current situation of middle school chemistry experiment teaching and middle school students’ "scientific inquiry and innovation consciousness" literacy,Provide a realistic basis for the teaching of innovative experiments;(3)Screening middle school chemistry experiments,selecting "brown bread" experiment,"breathing to make fire" experiment,"baking soda fountain" experiment,"copper tree" experiment as innovation objects;in order to better guide students to improve and innovate experiments in the teaching process,appropriately show teachers’ improvement ideas for students’ reference,and design the improvement plan of the experiment;in order to ensure the operability and safety of the innovative experiment,and the phenomenon of the experimental effect is more obvious,the above four experiments are experimentally verified;(4)For the improved experimental design teaching ideas,pay attention to the "student-centered" concept to guide students to improve the experiment;selecting two classes as the experimental class and the control class to carry out practical research.Through the above research content,the following research goals have been achieved:(1)Compared with traditional teacher-led experimental teaching,innovative experimental teaching can stimulate students’ interest in learning to a greater extent,change students’ inherent understanding of textbooks as absolute authority,change from passive acceptance to active construction,and students’ comprehensive application of knowledge.And the ability of experimental research has been significantly improved;(2)Improve middle school chemistry experiments and "student-oriented" innovative experimental teaching,enrich chemistry teaching methods,and improve the experimental exploration ability,innovation ability,experimental teaching ability,teaching concept of front-line chemistry teachers,and more In line with the requirements of teachers in the new era of educational concepts;(3)Carry out "student-centered" innovative experimental teaching,cultivate students’ innovative awareness,environmental protection awareness,dare to think,dare to question the spirit,etc.,and develop the core quality of "scientific inquiry and innovation awareness";(4)It cultivated students’ sense of teamwork,cooperation,patience,willpower,sense of achievement,etc.,which play an important role in realizing the comprehensive educational requirements of the society.
