Training And Research On The Design Ability Of Junior High School Students' Chemical Experiment Schemes

The new curriculum reform of chemistry in junior high school highlights the importance and role of chemical experiment teaching in chemistry teaching,and pays attention to the cultivation of students' experimental ability.The latest revision of the "chemical curriculum standard" in 2011 clearly points out: "teachers should fully understand the unique value of scientific inquiry in promoting the development of students' scientific literacy,attach great importance to and strengthen experimental teaching in the teaching,and give full play to the educational function of the experiment." At present,the chemistry curriculum in middle school is gradually changing from the knowledge of theory to the direction of cultivating the ability of scientific inquiry.The design ability of students' chemical experiment scheme has become the basic requirement of scientific inquiry.In this paper,the present situation of students' chemistry experiment design teaching situation in junior middle school under the background of the new curriculum is understood by the questionnaire about the students' ability to design the chemistry experiment program design of junior high school students.The study on the chemistry experiment of the junior middle school students in Liaoning experimental middle school is carried out.The results show that the design ability of the chemical experiment scheme has already been shown.It has become the weakest link in students' chemistry experiment.The concrete performance is that the students' experiment time is not enough,the students have less opportunity to design the experiment plan independently,and the design of the teachers is more dependent on the design of the experimental scheme,and the lack of creative thinking and flexibility.Therefore,strengthening the training of junior middle school students' chemical experiment design ability is a pressing matter of the moment.This paper puts forward teaching strategies to improve the design ability of junior high school students' experimental scheme:(1)train the design idea of experimental scheme(2)help students to clear the principle of experiment and excavate experimental ideas(3)help students to choose reagents and instruments(4)to help students establish scientific thinking mode(5)to create experimental situation,and improve experimental prosperity.Interest(6)carefully organized,with birth-based(7)set up subject review class,multiple channels to carry out inquiry teaching,and practice teaching in two cases.It is hoped that the above measures can effectively improve the design ability of junior high school students' chemical experiment program,and can play a positive role in cultivating high-quality talents with innovative ability.
