Research On The Effectiveness Of Teaching Of Chemistry Experiment In Senior High School Under The New Curriculum

Since the new curriculum reform in 2003, the position and function of chemical experiment in subject teaching is becoming more and more prominent.The author analyzes and interprets the new chemistry curriculum standards of senior high school chemistry curriculum standards and new teaching materials.The author observed that not only the total amount of chemistry experiment is obviously increased but also experiment teaching is required to be improved, the experiment undertakes the teaching function is expanded. What’s more. Students’scientific research experiment are added in "Scientific inquiry "column in the new teaching material, In addition, the teaching material also increases the students’ practical activities which requests the student to carry on the on-the-spot investigation, the investigation or the experimental verification in the study process.However, actual experimental teaching is limited by the teaching conditions. The teaching effect result in unfavorable states.The author hold the view that chemistry teachers need pay more emphasis on the effectiveness of high school chemistry experiment teaching in the course of the new curriculum reform.Under the background of new curriculum, effective teaching is a kind of activities which is organized to achieve the expected target and meet social and individual education needs.It aims at the improvement and development of the There-dimensional teaching demands made up of knowledge and skills,Process and Methods,Affect and Attitude and value.Therefore, whether the chemical experiment teaching is effective depends on the completion of the three-dimensional target in the process of experiment teaching. In order to improve the efficiency of chemical experiment teaching, it is needed to realize the effective control of the teaching process in the teaching process.It is found that there is a gap between the current situation of high school chemistry experiment teaching and the new curriculum objectives through questionnaire survey of teachers and students in LUXI.Such as most school lack of experimental apparatus, low open rate of chemistry experimental course.The main goal of the experiment teaching is to focus on the basic knowledge and skills.Students have only experienced the surface of the experiment teaching function.The way of promote students’scientific literacy inquiring ability is very limited,etc.In view of the above questions,the author puts forward some suggestions to improve the effectiveness of experimental teaching according to different experimental teaching practice experience and relevant research theory.Firstly we should strengthen the consciousness of teachers and students,then teachers should improve demonstration experiment in experimental teaching materials or experimental installation.also we can organize students to carry out experiments in a group so much as we may encourage students to actively participate in scientific inquiry, scientific and technological research and innovation activities.Besides,Through different forms of demonstration experiment teaching practice, I collect some datas for comparative analysis,the results show that the students who demonstrate the experimental teaching class can be easily tested by experimental skills.In this study, there are still some problems, such as the sampling range is narrow, the representative sample is not enough, fThe general significance of the experimental conclusion may be affected.And the lack of new curriculum standards in the study of three-dimensional target analysis of the actual experimental case analysis.In order to improve the effectiveness of experimental teaching, We need the joint efforts of our teachers and students,teaching process, the pursuit of purpose is tor improve the. effectiveness of experimental teaching in the classroom.Only by continuous research and understanding of the learning situation, we can design effective experimental teaching and improve our teaching level.
