Research On The Current Situation And Improvement Strategies Of High School Chemistry Experiment Teaching Under The New Curriculum Standard

Chemistry is a science based on experiment.Experimental teaching plays an important role in middle school chemistry teaching.It is not only one of the important means for middle school chemistry teachers to improve students' learning interest and teaching quality,but also an important way for students to understand and master chemistry knowledge.Through the exploration of experiments,students can understand the magic of chemical reactions,perceive the unique charm of chemistry,and thus obtain the key to open the door of the new world of chemistry.Under the guidance of the ordinary high school chemistry curriculum standard(2017edition),based on constructivism,recent development areas and other educational theories,with field investigation and questionnaire,the paper analyzes the current situation of high school chemistry experiment teaching,and find out the following main problems exiting:(1)the lack of experimental resources,can't meet the demand of experimental teaching;(2)There is a gap between the curriculum of chemical experiment and the new curriculum standard;(3)teachers do not pay enough attention to experimental teaching;(4)the experimental evaluation standard in the new curriculum is inconsistent with the actual teaching evaluation method;(5)in experimental teaching,students rely on teachers for learning and lack independent learning and hands-on ability.It also proposes five improvement strategies :(1)improve experimental facilities to provide basic support for experimental teaching;(2)develop the experimental courses of our school and improve the experimental opening rate;(3)improve the quality of teachers and attach importance to experimental teaching;(4)improve the evaluation system and increase students' confidence;(5)improve students' subjective initiative by using learning plans and micro-lessons.The previous four strategies serve as a reference for policy makers,this paper mainly combine study case and micro class to the teaching design and implementation,which is in high school chemistry experiment teaching,feedback information from the implementation of teaching shows two aspects.Firstly,in teachers' level,teachers can endorse this experiment teaching means,students have more enthusiasm to participate the teaching process,more desire to explore,more passion to answer question,and classroom have more learning atmosphere.In the other side,students in school which don't have perfect experimental conditions can feel the charm of experimental chemistry experiment.secondly,there are two advantages in students' level: This form of learning improves the efficiency of preview and helps to form the habit of autonomous learning.At the same time,they can keep upwith the teacher in the classroom,that improve the interest in learning chemistry courses and make full use of a lot of fragmented time to better grasp the knowledge.
