Thiết kế tình huống dạy học đồ thị hàm số môn Toán lớp 10 với sự hỗ trợ của phần mềm Geogebra

Tóm tắt

In the junior school math program, students understand the concept of graph y=f(x) as simply a collection of points representing pairs of numbers (x; y) in the coordinate plane without mentioning the value of which set does x belong to? In current Math 10, the concept of a graph of a function y= f(x) is a set of points with coordinates (x; f(x)) but x must belong to the domain of the function. To clarify the concept of function graphs according to the current Grade 10 Math program, we propose a way to design situation for teaching graph concepts with the support of GeoGebra software.
