Cabri 3D is one of dynamic geometry software. This software helps students with the visualization of 3D figures their properties. The purpose of this software is to help students to better understand three-dimensional space, since three-dimensional space is difficult to visualize. Cabri 3D allows students and teachers to construct and manipulate solid geometry objects in three dimensions. It provides a tool for teachers and students to explore properties of 3D geometric constructions
Even though it is Cabri 3D, two dimensions objects can still be created. The software is suitable with many two dimensions concepts such as length, sectors of circles, lateral area, surface area. Cabri 3D will help students to learn analyzing characteristics and properties of two- and three-dimensional geometric shapes and develop arguments of mathematics about geometrical relationships. Students also can learn to use visualization, spatial reasoning, and geometric modeling to solve problems
Cabri 3D is appropriate for secondary school students. Even though the software is not very user friendly, the students can be successful with the program if they learn through the manual. Teachers who want to use it in their classes have to be advanced in using it. Even though the software is not user friendly, it still offers a lot of great features that help student to get success in learning mathematics especially in geometry class.

Since you say this is not very user-friendly, and the teacher would have to be very knowledgeable about the software before being able to teach students to use it, you could still use this as a whole group demonstration or activity. That way, you can help all students with 3D visualization without spending too much time teaching them how to use the software. BUT if the software has a lot of great attributes, maybe it would be worth the time to teach them.
ReplyDeleteWow. That is awesome. I would have loved this software in the technical drawing class I took in high school. It was so hard for me to visualize irregular three-dimensional shapes, but this program seems like the tool to support understanding of such a difficult concept. The video on the URL you posted looks like the program can be used on a SmartBoard. That coincides well with what we learned in class today. You said this program is not very user friendly. Can you see some problems with this? Are you worried it might take too long to teach high school students how to use the software?
ReplyDeleteI agree with Maggie. From the video and your explanation I think a lot of training for the teacher is necessary for its potential in the classroom. I really like the way you can change the view of the 3-D shapes and see how the net comes together to make them. As a future elementary school teacher, I think a hands-on demonstration, by someone who is proficient in using this program, would be educational to young students. During my elementary school practicums and student teaching I have seen students struggle to grasp the net to 3-D shape concept and being able identify a 3-D shape when only seeing the net. This program would show these concepts in a new way that students would find cool and engaging.
ReplyDelete@Maggi: You are right, I should master the software before using it. a good thing is I can save a lot of time when I teach three dimensional shape by using the software.
ReplyDelete@Hunter: So do I, when I was in hight school it was really difficult for me to visualize there dimensional shapes.Actually it does not take a long time to teach students how to use it as loong as teachers have already prepared before the class.
ReplyDeleteThat seems like an interesting program. While it may not be the more user friendly program, it seems to definitely have potential. I remember in geometry class in high school I too had trouble picturing some of the shapes we were talking about and something like this could have been very helpful to me and I'm sure many of my classmates. So if the teacher was able to use it, it could even been used just for demonstration purposes.
ReplyDeleteWow! This program sure has got a lot of talk about it, and for good reasons! Cabri 3D, in my opinion, is a breath of fresh air in the geometry software world. I’m sure many of you that have ever taken a geometry class or know of any friends that have, are aware of the software Geometer’s Sketchpad. It is often times the only software program used to work with the subject, but is limited to 2D objects. I really enjoy that Cabri 3D allows students to work with the next dimension, as well as with lower dimension/level tasks. Watching the video on the website, I completely agree with the reasoning/purpose behind creating the software which is recognizing that students have a difficult time understanding how to visualize “opening up” a 3D shape. I am seeing this problem currently in my middle school practicum classroom. The students just don’t get it. Watching the teacher utilize the software on the video looked incredible! You can literally pull away the sides of a 3D figure and see what the shape actually looks like. I could most definitely see myself incorporating this software into my classroom, especially when teaching volumes and surface areas.
ReplyDeleteThanks for All, I am glad you all intested in Cabri 3D.
