| Outline of Final Research Achievements |
This research develop the algebraic curriculum emphasized spiral mathematical activities cooperated with junior and senior high school algebra, consider student's mathematical inquiry about school algebra and its effect by qualitative method. In this research we develop several teaching units such as possitive and negaive integer and complex plane emphasized number expanding, factorizing the polynomial, discovering and proving algebraic property of rational number sequence to come nearer infinite to square root 2, producing and interpreting the mensuration formula about circle and sphere. Various effects find out by student's learning process in these algebraic curriculum emphasized spiral mathematical activities.
