Math Module: Quadratic Equation, Quadratic Function and Inequality

admin — Thu, 11 Feb 2010 11:37:18 +0000

Other than in Junior High School, the material on quadratic equations are also studied back in high school. Likewise with quadratic functions and quadratic inequalities. Mathematical material is a material basis for the subsequent material, so that this material should be given since junior high. While in junior high, given the material was basic and not yet in high school complex. Quadratic functions and quadratic inequalities is also not too much given in junior high.
Several times to teach quadratic equations, one difficulty is when students want to factoring, without using the abc formula or the quadratic formula. Even until the 12th grade high school students were still experiencing difficulties in factoring. Is required for factoring a lot of practice experience. Also logic and reasoning power is needed.

Although such materials has ever been given in junior high, sometimes when repeated again in high school (grade 10), still many who forget, or do not remember at all, but the problems associated with these materials is also in the UN. Whose fault is it?

Maybe you’ve had an interesting experience while teaching the material? Or the difficulties in explaining to the students? Write your comment below. Your comments will be useful for teachers in other schools in Indonesia.

Well, this time I will make a link to download the module mathematics: quadratic equations, quadratic functions and quadratic inequalities.
