| The new curriculum standard emphasizes the importance of problem-based teaching.The column of "problem research" closely adheres to the educational idea of the new curriculum standard and encourages students to carry out research study by means of investigation,experiment,investigation and so on.It plays an important role in promoting the achievement of Students’ geographical literacy.However,the actual teaching situation of the column of "Problem Research" is not ideal due to the teachers’ lack of attention and tense class hours.Based on the basic theory of geography science,constructivism theory and the theory of the zone of proximal development,this article from the high school geography teaching material "the question research" column content,the characteristic,the classification and so on launches the analysis.Through questionnaires,interviews,classroom observation and other investigation methods to understand the current situation of column teaching,analysis of the problems and their causes.The author then carries out the analysis of the general teaching strategy and the teaching strategy of different column types to provide a feasible teaching reference for front-line geography teachers.The main conclusions are as follows:Firstly,through the analysis of the relevant contents of the textbook,it is found that the topic of the "Problem Research" column is comprehensive,which can be closely related to the unit content and expand the knowledge field.Its function is clear,which can carry out the course standard request practically and cultivate the core literacy of geography.It has diversity,can pay close attention to social hot spots,close to the actual life of students.Its space is open,can open the question inquiry space and expand students’ thinking field.On the basis of the existing classification,combined with the new curriculum standard,the "Problem Research" column can be divided into four categories: imaginative planning,problem solving,analysis and argumentation,and evaluation and reflection.Secondly,through questionnaire survey and teacher interview,it is found that the current teaching status of "problem research" column is not ideal.Teachers need to pay more attention to the column of "problem research" in teaching,and do not know much about the classification of the column.The frequency of column teaching is low and classroom teaching method still occupies a large proportion in practical teaching.Through classroom observation,it is found that an excellent "problem research" class can carry out theme-based teaching according to research ideas,deepen the understanding of a strong geographical knowledge,strengthen the cultivation of geographical core literacy,highlight the role of students in classroom teaching,pay attention to excavate ideological and political elements and mobilize the classroom atmosphere through process evaluation.However,the classroom control ability is slightly inadequate,the autonomy of students’ answering questions is neglected,and the evaluation degree needs to be improved.Based on the investigation content,the author analyzed the existing problems and their causes,and mainly concluded four points: students’ inquiry activities are insufficient,and the teaching mode still needs to be changed;The frequency of column development is low,and the teaching task is really heavy;It is difficult to carry out practical activities and the teaching conditions are deeply restricted.Lack of classroom control ability,the quality of teachers to improve.Thirdly,on the basis of the analysis of textbook analysis and teaching status,the general teaching principles of "problem research" column are put forward.It includes clarifying the research ideas,strengthening the exploration of teaching materials,insisting on the quality-oriented role,strengthening the innovative application of situation,emphasizing the learning and inquiry process,and improving the evaluation and feedback mechanism.Based on the classification of "Problem Research" columns and under the guidance of general teaching principles,the teaching strategies of different column types are put forward from the aspect of teaching process in order to guide the actual development process of the column.In order to further reflect the application process of the proposed teaching process,this paper selected four different types of "problem research" columns to carry out case design according to the proposed teaching process. |
