Cabri 3D는 학습과 기하학의 다양한 측면을 교육하기위한 명확한 교육학지도와 응용 프로그램입니다.
당신은 가장 복잡한하는 가장 간단한에서 모든 종류의 모양을 탐구하고 다른 원소와 그들을 결합 : 점, 선, 세그먼트, 원, 평면, 입체 개체 및 더욱 많은. 프로그램 Cabri의 3D의 다른 사용은, 만들어진 양식의 길이, 면적, 직경과 같은 매개 변수의 계산을 대수적 표현을 창출하고 그래서 on.This을 매우 포괄적인 프로그램, 그리고 적절한 모두 교사와 학생들을위한 것입니다.
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
operations.
- 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 and enlarging.
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 high-quality
printouts.
- Present activities to
students, have them manipulate figures, observe and guide them. Using
Cabri allows you to better assess individual student comprehension.
- 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 3D adapted especially for middle
school
In addition to the features common to all Cabri products, Cabri 3D includes:
Numeric and geometric tools
- Basic constructions with
planes, spheres and lines.
- Study of common solids: with a click of the mouse,
the student or teacher can construct pyramids, parallelograms, cylinders
and cones.
- Sections of solids: The user can represent and
determine planar sections of convex polygons.
- Unfolding polyhedron into nets: Cabri 3D unfolds
all polyhedron into nets, which are printable and can be reproduced onto
card stock.
- Measurements and calculations: Find measurements
related to objects - distances, lengths, area, volumes and angles, and
use them in calculations.
Unique 3D visualization tools
- Through tools that facilitate visualization,
students and teachers can:
- Adjust viewing angles turning around the scene
- Appreciate the rendering of depth of the scene.
- Animation tools:
Particularly stimulating for students, the tools enable them to
simultaneously put several elements of a construction in motion. It is
ideal for modeling physical phenomena.
- Different representations
and perspectives of
the same figure: the three angles of technical design, various
perspectives.
- « Refresh the construction » tool replays the user's construction.
