Research On The Teaching Of High School Mathematics Problem String Oriented To The Development Of Higher-order Thinking

The new curriculum proposes a "people-oriented" teaching concept,and advocates a teacher-led and student-based classroom teaching model.Under the guidance of the new curriculum concept,with the help of inherently logical question strings and teacher-student questions and answers that are in line with students 'psychological development,students' higher-order thinking skills such as discovery,analysis,evaluation,and creativity are cultivated.Higher-order thinking is a mental activity and cognitive ability at a higher level of cognition.It' s development depends on the inspiration and guidance of problems.Good question strings can build students' thinking channels,and enrich and improve the process of analyzing and solving problems.The development of students' higher-order thinking promotes their thinking from low-level to high-level,and continues to mature.So how to design a hierarchical and progressive question string,how to combine the question string teaching with the training of higher-order thinking ability,it is worth our exploration.The article mainly uses the literature analysis method,questionnaire survey method,experimental research method and interview method.Combining the research context of problem strings and higher-order thinking through literature analysis,combined with high school mathematics textbooks,studied the types and design principles of problem strings oriented to the development of higher-order thinking,and aimed at the development of "analysis,evaluation,creation,and criticism".Research on question-chain teaching activities at the level of high-level thinking and provide design schemes.At the same time,carry out control experiments,use questionnaires to analyze the impact of question-chain teaching on the development of higher-order thinking,and further investigate the students in the experimental class on question-chain teaching through interviews Evaluation,and finally put forward corresponding teaching suggestions.The following conclusions are obtained through research:(1)Question-chain teaching plays an active role in the development of higher-order thinking.Students in the experimental class have significantly improved in the four levels of higher-order thinking: "analysis,evaluation,creation,and criticism."(2)Students who have experienced problem-based teaching can like and adapt to thisteaching method.Based on the research conclusions,the corresponding teaching suggestions are put forward:the first aspect is to start from the problem string design,from the perspective of situation creation,scaffolding,guidance of doubts,variant design to design and develop high-order thinking problem strings;the second aspect It starts with question-teaching activities to develop students' higher-order thinking,such as question-teaching activities that use the combination of numbers and shapes as the basic thinking method,teaching activities that focus on the best points of question-string design,reflective question-teaching classroom activities,and inquiry.Question string teaching activities.
