Cabri II Plus的功能
•Basic 工具： 指南針、 丁字尺
•Numeric 和代數工具： 協調點、 線的方程、 函數和表的圖形表示
The player will show in this paragraph Cabri II Plus is a software
recognized by experts in pedagogy, specifically for its simplicity
of use and solid educational foundation.
Cabri: Software serving pedagogy
Tools for students: « from exploration to understanding »
With just a few clicks, students can:
•Construct 2-D and 3-D figures,
from the simplest to the most complex, by combining fundamental
geometric objects such as points, angles, segments, circles, planes,
solids and transformations.
•Create expressions using
fundamental algebraic concepts, such as numbers, variables and
•Connect geometry and algebra
by measuring length, angles, area and volume and then attaching
these numeric values directly to the figure to use them in
calculations or in algebraic expressions.
•Explore a figure's
properties by manipulating its variable elements.
Observe the effects of dynamic transformations like shrinking
Make conjectures about algebraic and geometric properties,
and then verify relationships among various parts of a figure.
Tools for teachers: « from lesson plans to assessment »
The teacher can:
•Create activities that:
- facilitate the introduction and understanding of new concepts
- promote the discovery of theorems, instead of just showing them
- help model real-life situations.
•Generate classroom resources
by inserting text or pictures in a figure, modifying graphical
elements, copying/pasting into other software and producing
•Present activities to
students, have them manipulate figures, observe and guide them.
Using Cabri allows you to better assess individual student
•Expand online by integrating
figures that can be manipulated on web pages or by incorporating
Microsoft Office® documents.
•Have students solve problems
directly linked to the NCTM standards with possible
interdisciplinary connections to physics, geography and the arts.
Focus on the features of Cabri II
Building upon the features common to
all Cabri products, Cabri II Plus adds:
Tools for new learning opportunities
tools borrowed from traditional design tools: compass, T-square
- place and trace: display the paths of geometric figures when they
- redefine objects: add or subtract constraints on the relationship
between the objects in the figure.
and algebraic tools: coordinate points, equations of lines,
graphical representations of functions and tables
Tools that can be personalized to meet
each teacher's needs
the history of figures: simultaneously follow the work of several
students by replaying each of their actions step-by-step.
your own tools in order to remake frequently used constructions in
just a few clicks. Design « black box » tools whose functions are to
be discovered by the students.
