Research On The Application Of POEC Teaching Strategy In High School Chemistry Teaching

Since the promulgation of the new curriculum standard of high school chemistry,it is clearly proposed that the cultivation of students should be based on "accomplishment".At present,high school teaching tasks are heavy and the pressure is great.The focus of high school teaching is mainly on imparting knowledge and skills.There are problems such as students’ weak independent learning ability,insufficient scientific inquiry ability,difficult to form high-quality thinking,communication and interactive activities,and insufficient understanding of the value and significance of chemistry in production and life.And POEC teaching strategy can better solve the above problems.The implementation of POEC teaching strategy can stimulate students’ interest in learning,enable students to consciously predict(P)-observe(O)-explain(E)-compare(C),clarify the cultivation focus for teachers in every link of classroom teaching,internalize knowledge between teachers and students through exploration and communication interaction,and develop students’ core quality of chemistry.The basic concepts of "POEC teaching strategy" are prediction(P)-observation(O)-explanation(E)-comparison(C).This strategy takes students as the main body and teachers as the guides of classroom teaching activities.The whole research includes theoretical research,practical research and analysis of research results in three aspects.Firstly,based on the relevant theoretical basis,this paper reviews the domestic and foreign research progress related to this topic,determines the educational research methods and research ideas,analyzes and defines the relevant concepts,writes the principles to follow the POEC teaching strategy,carries out the experimental pre-test analysis on this basis,and draws the feasible opinions on the implementation of the POEC teaching strategy.It provides powerful theoretical support and condition support for the smooth development of the research.Secondly,it discusses the design basis of POEC teaching strategy,puts forward the ideas and means of teaching evaluation,carries out teaching design cases,and reflects the idea of task-based and modular design of case in teaching design.Finally,according to the teaching arrangement of the practice school,the teaching practice research is carried out with one of the teaching cases "Ethanol",and the students’ learning situation under the guidance of this strategy is evaluated quantitatively and qualitatively through multi-dimensional evaluation.The quantitative evaluation is based on the experimental inquiry evaluation scale,the learning experience questionnaire,the classroom observation scale and the data before and after the monthly test.The qualitative evaluation is based on the self-evaluation of students’ learning activities,the mutual evaluation of students’ learning activities,the evaluation of teachers’ teaching activities and the interview of teachers to obtain the qualitative results.Finally,the analysis of goal achievement degree evaluates students’ knowledge learning and ability cultivation.The results show that: first,students under the guidance of POEC teaching strategies have higher classroom participation and better learning enthusiasm;Second,learning under the guidance of POEC teaching strategies can effectively improve students’ learning ability,thinking level and spirit of scientific inquiry,and promote the effective implementation of classroom learning;Thirdly,POEC teaching strategy is suitable for cultivating students’ core quality of chemistry subject,which can help to improve chemistry scores and has a great positive promoting effect on the improvement of students’ thinking,practice and value.Due to the limitation of the content arrangement of the educational practice and the teaching schedule of the practice school,the sample selected for the investigation is limited,and the content involved in the empirical research is less.Therefore,it is necessary to continue the practical research on it in the future teaching work,in order to obtain more comprehensive and reliable conclusions.
