A Study Of Senior High School Chemistry Classroom Teaching Situation And Creation Strategy

With the continuous reform and development of education,the educational ideas of teachers are constantly changing and updating.More and more educators begin to pay attention to the application of situation in teaching,and the creation of chemistry classroom teaching situation has become an important research topic in teaching practice.However,many front-line teachers still have misunderstandings in their understanding of the teaching situation,and can not give full play to the value and role of the situation in the actual teaching process.On the basis of referring to the relevant literature of teaching situation at home and abroad,this study summarizes teaching situation from multiple dimensions such as research background,research status,theoretical basis and concept definition.Then,based on the classification of teaching situations by a number of scholars,the classification basis of high school chemistry classroom teaching situations is determined,and the situation is divided into thematic situation and fragment situation according to whether the situation runs through the whole classroom teaching process.According to the source of the situation materials,the situation is divided into life situation,science and technology situation,chemical production situation,experiment situation,chemical history situation,knowledge situation,student activity situation and exercise creation situation.According to the above classification standards,this paper classifies 26 samples of high school chemistry classes in a certain City,studies the situations involved in them from three aspects of composition characteristics,functional characteristics and process characteristics,analyzes the status quo of high school chemistry classroom teaching situation creation,and sorts out the status quo patterns and problems of high school chemistry classroom situation creation.Based on this,the author puts forward the strategy of setting up the teaching situation of high school chemistry classroom,that is,teachers should improve the awareness of curriculum resources and accumulate the situation materials extensively.Select materials close to the actual situation of students’ life;The teaching situation should contain the subject problem and the subject core teaching content;The problem tasks contained in the teaching situation should stimulate students’ higher order thinking;The teaching situation should include the education of students’ discipline spirit and attitude;Create more thematic teaching situations,so that the situation throughout the classroom.Finally,using the strategy proposed above and taking the typical element compound knowledge "The Nature of Ammonia" in high school as an example,the teaching design based on the teaching situation is carried out and implemented in the classroom teaching.The investigation shows that the effect is good,which provides a reference for the situation creation of the first-line chemistry teachers in high school.
