An Experimental Study On Cultivating Grade One Students' Number Sense By Mathematics Picture Book Teaching

A two-factor mixed experiment design of 2(time: pre-test/post-test)×2(group: experimental group/control group)was adopted to investigate the influence of picture book teaching on the number sense of first-year students.Start with qualitative analysis,this study based on piaget's cognitive development theory to build mathematics picture books teaching activity system,picture books in mathematics teaching goals,starting from the overall goal for longitudinal hierarchy goals and transverse three-dimensional goals;When selecting mathematics picture books teaching activities,and experts,a line of the mathematics teachers draw this filtered according to certain standard and study.Finally choose eight this close to the teaching material,in line with the subjects of cognitive experience mathematics draw this design teaching activities,and implement.From the point of quantitative analysis,this study divided60 subjects into experimental class and control class for a total of 8 intervention studies for 4 weeks.The experiment analyzes the four main dimensions of number sense of the subjects,and focuses on the help of the students with slower development of logarithm sense in mathematics picture books,and obtains relevant data.Then,the descriptive qualitative research method is used to go deep into classroom activities,and the performance of teachers and students in the integration of mathematics picture books into teaching activities is recorded in detail from the subjective perspective,and the experimental hypothesis is supported and judged from the on-site facts.In this study,quantitative analysis and qualitative analysis are combined to study the influence of math picture books into first-grade math activities,and the research results can be obtained from many aspects,multiple levels and multiple perspectives.The results show that :(1)mathematics picture book teaching activity can promote the development of first-grade students' number sense ability;(2)The math picture book activity effectively improved the score of the first grade students' counting dimension,quantity conversion dimension and number type dimension;(3)Students with poor logarithmic sense ability in mathematics picture book teaching have a more significant influence,which is mainly reflected in the dimension of number and number type.
