数学学科核心素养导向下的教育数学实证研究OA北大核心CSTPCD

Educational Mathematics experiments play an important role in the educational reform of China,and the development of students'mathematical key competencies is regarded as one of the significant indicators of the effectiveness of the reform experiments.In this paper,an evaluation framework of mathematical key competencies for middle school students is selected to evaluate the Educational Mathematics experiment conducted in Qionglai City,and the impact of the experiment on the development of students'mathematical key competencies is analyzed.First,the mathematical key competencies involved in the paper of the second diagnostic test paper for students of Grade 3(i.e.,students enrolled in 2017)are classified according to the selected evaluation framework.Second,based on scores of students'mathematical key competencies,a comparative analysis was conducted on the development of mathematics key competencies among 3 672 junior high school students and 93 students in educational mathematics experimental classes in the city.The results show that:city's overall key mathematics competencies development among junior high school students is unbalanced,especially on aspects of mathematical modeling competency and logical reasoning competency;however,the development of the mathematical key competencies of the students from the experimental class is more balanced,and generally better than the overall level of the city.In conclusion,Educational Mathematics can promote a balanced development of students'mathematical key competencies,the experimental risks are controllable,and the Educational Mathematics is suitable for large-scale popularization.
