| This round of new curriculum reform is the strongest in the history of China’s education reform.Many educators and researchers have actively invested in it and achieved remarkable achievements.Problem-based learning(PBL)is booming in this background.PBL takes problems as the core and students as the main body of classroom activities,focusing on cultivating talents who meet the requirements of the times.Based on PBL teaching theory,this paper aims to solve the problem of "difficult learning and difficult teaching" of function in senior high school.On the one hand,it makes bricks and tiles for the implementation of effective classroom teaching method,on the other hand,it also guides the direction for students’ lifelong learning.In the early stage of the research,the author mainly reads and arranges the literature of PBL at home and abroad,writes a summary,and analyzes the differences between PBL teaching method and other teaching methods.Secondly,the author understands the current situation of students’ function learning through questionnaire survey,teacher-student interview and other methods,and formulates a practical PBL teaching model on the basis of the existing theory and known learning situation,so as to make full preparations for practical teaching.Based on the PBL teaching model,this study makes teaching design and experimental research on exponential function and logarithmic function.The experimental research is divided into two rounds.The first round of experimental results show that PBL teaching is not only conducive to the improvement of students’ mathematics learning performance,but also very effective in improving students’ interest and attitude in mathematics learning,and these conclusions are more obvious in the evaluation of students with good mathematics foundation.The second round of experiment improved the deficiencies on the basis of the first round of experiment.The improvement focus is to effectively combine PBL teaching with teaching method.The results show that the effective combination of PBL and teaching method can promote students’ learning effect better than single PBL teaching,and students with weak mathematical foundation benefit more from experiment two;At the same time,experiment two also shows that the long-term use of PBL teaching is conducive to the development of students’ concept of lifelong learning.The innovation of this study includes the construction of PBL teaching model and the design of experimental scheme.In this paper,the PBL teaching model in line with the learning situation constructed based on the theoretical and practical basis is highly operable.The first experiment of the research and design not only proves the effectiveness of the model,but also finds its shortcomings.Then the second experiment proves that the improved PBL teaching model is more conducive to the improvement of students’ learning effect.In the conclusion and prospect,the author believes that the rational use of PBL teaching can have a positive impact on students.It can cultivate students’ cooperative learning intention and expand students’ mathematics learning methods.Finally,the author suggests that front-line teachers should actively interact with educational researchers and quickly and effectively contribute to the development of China’s education in the combination of theory and practice. |
