Enhance the Understanding of Gifted and Talented Muslims Student’s on Quadratic Functions Using GeoGebra

GeoGebra is one of the teaching tool conducted by educator implement into their lesson plans to improve teaching and learning quality, make the classroom lesson more enjoyable, creative and innovative. Students can construct a graph, modify and observe the effects of changing graph shape. Moreover, students can be saved all their works documents for future reference systematically. The aim of this research was to analyse the application of GeoGebra on mathematics achievement in relation to the quadratic functions among gifted and talented Muslims student’s at Kolej GENIUS Insan, Universiti Sains Islam Malaysia. The effects of changing the coefficients values on the graphs of quadratic functions was identified. The results illustrate that changing in value of coefficient aon quadratic functions affects the shape and width of the graph, but, not the y-intercept. The position of the vertex on y-axis is only affected by changing the value of coefficient b, but the shape of the graph and the y-intercept remain unchanged. The shape of the graph is unaffected by changing the value of coefficient c, which only affects the location of the graph vertically upwards or downwards. Students' performance in understanding the effect of quadratic graphs improves when they use GeoGebra software.
