| The Chemistry Curriculum Standards for Ordinary High School(2017 Edition)puts forward the core quality of chemistry in high school,including five dimensions such as "scientific inquiry and innovation awareness",which covers a wide range.However,in high school chemistry teaching,it is still a problem worth studying how to implement the cultivation of the core quality of chemistry in all aspects of the classroom.Chemical experiment runs through the whole process of chemistry teaching.The author selected the core quality of "scientific inquiry" closely related to the experiment for in-depth research.This research takes the cultivation of students’ scientific exploration literacy as the starting point,combined with the difficulties faced by the current experimental teaching,through improving some teaching materials and experiments,and integrating the improved experiment with the classroom teaching,the results show that the improved experimental teaching has a significant effect on improving students’ scientific exploration literacy.In the research,the questionnaire survey method was used to measure the status quo of the scientific inquiry literacy of a senior high school students in Shaoxing.Combined with the questionnaire survey,the survey object was taken as an example to analyze the development level of the current students in scientific inquiry literacy,and put forward the corresponding training strategies;By means of interview and field visit,the current situation of chemical experiment teaching in the practice school was investigated to understand the current situation of experimental teaching in the school,the conditions of experimental teaching in the school,and the difficulties faced by the current experimental teaching.Through sorting and analyzing some collected data,it can be found that due to the limitations of laboratory conditions,class tasks and other objective conditions,the school did not pay enough attention to chemical experiments and did not give students enough opportunities to do experiments,so it is difficult for students to develop their scientific inquiry education well.Fully consider the objective status quo of the current experimental conditions of the internship school,and combine the current research direction of improving the experiment,select the appropriate improvement plan to carry out teaching practice;In the improvement experiment selected in this study,conventional glass instruments and daily necessities such as "single row tube" and "pen shell" are used to carry out students’ experimental exploration.Through creating real problem situations,scientific exploration activities are carried out to cultivate students’ scientific exploration literacy.Through the scores of the corresponding exercises of the students’ scientific inquiry ability and the changes of their scientific literacy ability before and after the teaching practice,the following conclusions are obtained: First,improving the experiment improves the students’ cognition of chemical experiments and promotes their scientific inquiry literacy level.2、 The improvement of experimental teaching has improved the subject achievement of scientific inquiry ability in the examination questions.3、 This paper provides some solutions and suggestions for the difficulties that may be encountered in senior high school chemistry experiment teaching. |
