%T On The Teaching Of Analyzing The Effects Of Parameter Changes 
On The Graph Of Function

%X The proficiency level of some tenth and eleventh graders on analyzing the effects of parameter changes on the graph of function is observed in this project. The result shows the level is low. It seems that those students did not sufficiently work on math problems involving deep reasoning. The students used to solve math problems by plugging in formulas only. In this project, the causes are found and reported. At the end part, an alternative teaching approach is proposed.
Key Words: parameter, graph of function, alternative teaching
