Study On Teaching Strategy Of Chemical Conceptual Principle Based On Core Literacy

It has been more than ten years since the curriculum reform of ordinary senior high schools in China,and the achievements have been remarkable.However,in the face of the rapid development of science and technology economy and the new requirements of the times to improve the quality of all the people and train qualified personnel.The current standards still exist mismatch and inadaptability,and need to be reformed urgently.In order to cultivate high quality citizens to adapt to the new era,we must develop students' core literacy,and the formation of students' core literacy needs to be carried out in specific classroom teaching.The knowledge of concept and principle in the compulsory course 1 of Senior one is abstract and important,which plays an important role in the formation of students' core competence.But a lot of literature have shown that many researchers only study the chemical concept principle or core literacy unilaterally,and lack the teaching strategy of concept principle under the guidance of chemical core literacy.Based on the above situation,I put forward the teaching strategy research of concept principle based on the core competence of chemistry.The research of this subject is expected to provide a reference for the reform of chemical theory and practice.Based on the study of constructivist learning theory,humanism learning theory and cognitive learning theory,the author has conducted more than 3 months research on students of Grade 3 and 4 in a common middle school in Guilin.The research process is mainly divided into four parts.Firstly,based on the related research of chemical core literacy and concept principle,this paper compiled questionnaires and interview results.Two parallel classes of Class 3 and Class 4 in a senior middle school in Guilin City were selected as the research objects.At the same time,different levels of students were selected for interviews through questionnaires and interviews to understand the implementation of the chemical core literacy in the actual classroom and the current situation of teaching knowledge of chemical concepts and principles.Secondly,this paper is based on the knowledge of the concept principle and the development needs of students' chemistry literacy.This paper puts forward the teaching principles of the concept principle under the guidance of the chemical core literacy: the principle of subjectivity,the principle of stage,the principle of systematization,and the corresponding teaching strategy: creating the situation.introduction of concepts,picture presentation,formation of concepts,problem-driven,understanding concepts,comparativeanalysis,deepening concepts.Thirdly,in order to test the feasibility and effectiveness of the above strategies,we use PEP High School Chemistry Compulsory 1 Learning Contents as Carrier and apply these strategies to classroom teaching.Fourthly,in order to evaluate the results of the experiment,this study again sent out questionnaires and interviews to the students of the two classes.SPSS20.0 was used to analyze the students' test scores.Through the processing and analysis of the survey results,it is concluded that based on the principles of subjectivity,periodicity,and systematicness,and the deepening of the concept teaching strategy,all these are helpful for students to increase the enthusiasm of learning the concept of chemistry,to invigorate the classroom atmosphere,to help students understand more deeply the principles of chemistry concepts,and to transfer and apply them.It provides a method for students to learn abstract concepts and principles.At the same time,it is beneficial to the improvement of students' chemistry core literacy level,and proves the effectiveness of the teaching strategy constructed in this study.It is an important task to implement the core accomplishment of chemistry to chemistry teaching practice,which needs to be continuously explored.Due to the limited scope of the research object,the time of the study and the practical ability of the author,the teaching strategies and conclusions proposed in this paper need to be further examined and improved.
