T Middle School Stratified Classroom System In High School Chemistry Teaching Design Problems And Solutions

With the rapid development of society,education has to keep pace with the changing times.If we continue to cultivate the current students by following the previous basic education experience and guidance,we will make the current students just stand still and cease to make progress.And it will also make them unable to adapt to the high demands of the new society,which will further lead to their lack of social competitiveness.In 2021,Sichuan Province will carry out a new college entrance examination model called 3 plus 3,which will obviously cause that the traditional class teaching system can no longer be applicable.Education reform is in progress,and the instructional modes are also transforming with it gradually.For example,there has been a rise of the stratified shift system in recent years,which is an important new teaching form emphasizing stratified teaching after stratified course.In order to better realize the transformation from the traditional fixed class teaching system to variable class selection system,this thesis studies the stratified shift teaching in the transitional period.The main content focuses on the study of stratified walking class teaching firstly,and then combines with the present situation of the high school chemistry teaching desigh in the research object of T middle school,which is currently carrying out the stratified shift class,and after that finds out the existing problems and also makes stratified teaching design.This thesis mainly uses the methods of literature research,classroom observation,questionnaire survey,interview and other methods to carry out the research.First of all,this thesis analyzes a large amount of relevant literature,unscrambles the status of domestic and foreign research on stratified walking class and the research status of high school chemistry teaching design in stratified class system.And on this basis,it puts forward the theoretical founbdation,and also defines the concept of stratified walking class and high school chemistry teaching design.Next,combined with the situation of T middle school that is fully carrying out the stratified shift class,through the questionnaire survey and the classroom observation,it is found that most high school chemistry teachers in T middle school do not make a stratified teaching design previously in the course process of stratified class teaching.As aresult,the teaching effect of the actual stratified shift class is not very ideal,and the on-site class becomes informal and uncontrollable.So the content of this thesis then analyzes the learning situation of different levels after stratification,and carries out the three-dimension teaching goal stratification design.And it leads to the important content of the thesis,that is,combining the teaching concept of stratified shift class system and the learning situation of different levels of students,the case of stratified teaching design of the Chemical Balance in the second section of the high school chemical version is devised in detail.The following part also records the stratified teaching design case applied in classroom teaching.And through the interview after class with the teachers and students who participate in the class,and the analysis of the students' homework after class,finally here draws an important conclusion,which reveals under the background of stratified class walking system,it is really very necessary to carry out the targeted stratified teaching design before class.Through the study of this thesis,it is expected to provide some useful suggestions for the general middle school teachers in the high school chemistry teaching of stratified class.And it is also expected that our teachers can adapt to the new teaching mode as soon as possible,and can make the teaching design suitable for students at different levels according to their learning situation and the actual needs.Let's work together to promote the reform and development of chemical education!...
