Review Design And Practice Of Chemistry Experiment In Senior Three Based On Project-based Learning

The new education reform focuses on strengthening the guidance of students' core values and implementing the basic task of moral education.Chemistry is an experiment-based subject,which reform emphasizes the importance of chemistry experiment teaching,the transformation of students' learning mode,and the cultivation of students' practical ability and innovative spirit.There are some problems in traditional chemistry teaching,such as the importance of chemistry experiment is ignored,teachers' education idea is not advanced enough,chemistry experiment teaching is not interesting enough,and students' participation is not high.Project-based learning mainly adheres to the educational concept of “learning by doing”,which can bring students into real situations to cultivate their ability to solve practical problems,make them feel the practicability of chemistry discipline,and cultivate students' learning mode of “autonomy,inquiry and cooperation”.It is beneficial to change students' learning methods,deepen the reform of chemistry course and promote the implementation of chemical experiment teaching strategies under the background of new college entrance examination.In this paper,project-based learning is applied in the chemical experiment review teaching of senior three to achieve the basic strategies of chemical experiment teaching under the new curriculum standards,and to promote the cultivation of students' comprehensive ability.First of all,the characteristics,links and educational significance of project-based learning are understood through literature research,the research results of project-based learning in China and overseas are summarized and reflected,and the research objectives,ideas and methods are confirmed.This paper sorted out the recent college entrance examination chemistry experiment questions,combined with the High School Chemistry Curriculum standard,Chinese College entrance Examination evaluation system and so on to build the Preparation of mole salt,Determination of dissolved oxygen in water and Sodium thiosulfate industrial production method and other project learning of the chemical experiment review teaching of senior three.Secondly,two classes of senior three in a middle school in Xiamen with no significant differences were selected for comparative practice.The experimental class is adopted the teaching method of project-based learning,while the control class is used the traditional teaching method of chemical experiment review.By means of group evaluation,teacher evaluation,paper and pencil test,student interview and other comparative analysis,the practical results show that the experimental class is better than the control class,indicating that the project-based learning can be applied to the chemistry experiment review teaching.Finally,according to the practice process and result analysis,project-based learning is beneficial to promote the implementation of the new curriculum standards teaching ideas,deepen the reform of chemical education,stimulate students to explore thinking,cultivate practical ability and innovative spirit.This paper provides some references for the application of project-based teaching in the review of chemistry experiment of senior three,and puts forward some relevant suggestions for the application of project-based learning in the design and practice of review of chemistry experiment of senior three,and reviews the deficiencies in the process of practice,to make a summary and reflection on the improvement,to provide some practical basis for the follow-up research.
