Study on set function concept developments characteristics for junior high school students. (Chinese)
J. Math. Educ. (Tianjin) 12, No. 2, 55-58 (2003).
The development characteristics and levels of junior high students’ set function concept were studied through 693 students from grade one to grade three in 5 middle schools located in Beijing. The results showed that the set function concept development levels were lower at grade two than at grade one and three; there were not obvious differences between gender, grade factor, school factor or gender plus grade factor had obvious effects on students’ set function concept development. There were remarkable differences (p$<$0.05) between grade two and three by multi-level comparing analysis; mathematics education quality effects the set function concept development.
