The application of geometrical drawing board in modern teaching

Step into the multimedia teaching era, the production of good teaching courseware is also a teacher's ability to reflect, will also have an impact on the teacher's rating. Then say again, as the saying goes, paddle, for teachers are such, want to make a particularly good teaching courseware, choose a good tool is the first step! In the complex network world, the online auxiliary teaching tools are particularly many, many teachers are very difficult to find a suitable for their own, the following small series to bring you an auxiliary teaching necessary tools ----

The application of geometrical drawing board in two-times function

As in the "two-time image of function Y=ax^2+bx+c" section, how to explain to the students y=ax^2, Y=ax^2+k, Y=a (x-h) ^2, Y=a (x-h) ^2+k and other functional images of the relationship has always been the focus of the traditional teaching and difficulties, students are difficult to understand, Teachers are also difficult to explain in text language. Through the "geometric artboard" just move up and down the point A, H, k,y=ax^2, Y=ax^2+k, Y=a (x-h) ^2, Y=a (x-h) ^2+k and other functions of the image can be at a glance, the problem will be solved, students also in A, H, K changes in the process of deepening the understanding of two functions.

Application of geometrical drawing board in Triangle midline

Geometry artboard is a simple tool for mathematics teaching, such as: In the computer with the "geometric artboard" software to draw any triangle, and then draw its three lines, what is the law? (Triangle three lines at one o'clock) then drag the triangle's vertex A to change the shape of the triangle, to see if the law changes.

Application of geometrical drawing board in triangle inner angle and inside

In the study of the inner corner of the triangle and a class, we can use the "geometric artboard" software on the computer to draw any triangle, measure its internal angles and calculate their and, and then drag the vertices to change the shape of the triangle, and then the change of the internal angles of the calculation of the inner corner and. Thus the conclusion of "triangle inner angle and equal to 180 degree" is obtained.

About the geometry artboard

The geometry artboard is a software platform for geometry (plane geometry, analytic geometry, mapping geometry, etc.) produced and distributed by US key curriculum Press, which provides teachers and students with an environment to explore the intrinsic relationship between algebra and geometry. The software is short and powerful, can dynamically represent the relationship of related objects, the main service object is mathematics and physics teacher, the user can make the professional teaching courseware through the geometry artboard. has been widely used in the first high school teaching in the country, is one of the most outstanding teaching software.
