| Since the new curriculum reform,a great variety of teaching modes have emerged in our country to meet the needs of reform and development.Some of these teaching practices have also achieved good results to some extent,getting rid of the traditional teaching methods based on inoculation,So that teachers began to stand on the position of students to organize teaching activities.However,due to the inherent concept,the pressure of further study and the lack of teachers' deep understanding of educational philosophy and other factors,there have also been such problems as " a change in form but not in content" and hinder the further development of teaching reform.Since the middle and later of the 20th century,with the continuous deepening of related research on "problem solving" in our country,experts and scholars have begun to expand from the research in the field of psychology to the field of pedagogy,with more research dimensions,including teaching design,teaching strategies,Student development,teaching mode,etc.(some of which are based on the actual situation of first-line teaching).After the test of practice,teaching-related practice based on"problem-solving" has shown its own value and superiority.Through the sorting and analysis of relevant documents,the author finds that there is still room for further research:the existing research is less specific to one subject in primary school and less likely to focus on primary mathematics;the teaching on "problem solving" The study of model lacks the suggestion of specific application of frontline teaching and related application cases.Based on the literature review and case study,this study mainly studies three questions:how to construct a "problem-solving-oriented" teaching model based on the relevant requirements of the new curriculum reform and combing the previous research results,and clarify this model Basic characteristics,infiltration of the basic concepts and specific implementation aspects?How to use the first-line teacher"problem-solving oriented" teaching model for teaching design?"Problem-solving oriented" teaching model in the practical application of what problems may occur,what are the implementation Suggestions?The specific links of the "problem-solving oriented" teaching mode proposed in this study include "highlighting the key points,introducing the situation,asking questions,triggering thinking,collaborating on exploration and reaching consensus,and applying feedback to expand and enhance." The essential difference between these links and other teaching modes lies in that they pay more attention to the integrity among all aspects of teaching and knowledge,and encourage teachers to design their teaching from a more comprehensive and connected perspective.In addition,this study focuses on the application of "problem-solving oriented" teaching model in primary school mathematics teaching.By making a general analysis of primary school mathematics teaching design and putting forward different design suggestions for different course types,this study provides first-line teaching more clearly A new idea.Finally,based on the practice in the first-line schools,this study analyzes the problems that may appear in the process of using patterns such as the change of concepts,the understanding of core ideas,the creation of problem situations,and puts forward some suggestions.At the same time,starting from the actual situation in the field,this study gives the concrete design of six kinds of elementary mathematics lessons in two types of courses.These designs have achieved good results in practice and application,but they need to be further expanded and verified. |
