GRAPHING CALCULATORSANDSTUDENTS’ ACHIEVEMENT
“Mission: Through Career and Technological Education, students identify and pursue career goals, apply communication and critical thinking skills, develop employability skills, and plan for further education and employment.”
TI reported that:
A growing body of research* shows that graphing calculator use improves students’
1- Compared midterm results among 6 algebra 2 midterm. All classes are sophomore concept classes. 2 of these classes are taught by teachers who stress the use of graphing calculators. The others are taught by teachers who don’t use graphing calculators much.
2- Concentrate on Quadratic Equation presentation and testing:
Compared 2 teachers covering chapter 5 (quadratic equation). One of the teacher did not use graphing calculator the other did.
Assessment: Students in the class using the graphing calculator were able to recognize and match the functions with the graph, solve quadratic equations, identiry the effect of the parameters and identify cases of no solution using the (h-k) format and the graph in 2/3 of the time and more accurately than the other class.
