Mathematiques et sciences physiques avec Geogebra (Daniel Mentrard)

Mathematiques et sciences physiques avec Geogebra (Daniel Mentrard) | CEET Meet (Oct'2011): GeoGebra 101 ~ Linda Fahlberg Stojanovska | Scoop.it

A collection of activities, dynamic animations and interactive simulations for learning to understand the foundations of mathematics curricula and physical sciences at all levels.


This site is intended for students, parents, adults, but also to teachers (and educators) that can be used advantageously in their classes.

 

Graphics, appropriate use of color, design dynamic activities carried out with the excellent free software GeoGebra and the use of media images, are used to break the austere image suffered by the mathematical thinking and science.

Creating a 'moving target point' quiz item in Moodle | LFS

Creating a 'moving target point' quiz item in Moodle | LFS | CEET Meet (Oct'2011): GeoGebra 101 ~ Linda Fahlberg Stojanovska | Scoop.it

Using an Object Target type question. I added 3 types of questions. All you do is download and copy them as directed. [Caution: 2 people have complained that when using Chrome, they could not get target to move.]


Suggestion: Object Target requires that the image be at least 90 pixels height – so if like me you are using a toolbar, I extended it transparently to 90 pixel height.

(1) Drag drop matching at http://moodle.org/mod/data/view.php?d=13&amp;amp;rid=975

(2) Image target at http://moodle.org/mod/data/view.php?d=13&amp;amp;rid=977

(3) Drag and drop ordering at http://moodle.org/mod/data/view.php?d=13&amp;amp;rid=978

Regular polygons and their diagonals | David Radcliffe

Regular polygons and their diagonals | David Radcliffe | CEET Meet (Oct'2011): GeoGebra 101 ~ Linda Fahlberg Stojanovska | Scoop.it

Dave created this applet in response to the question: How do I add the diagonals at any instance? (Ans: The diagonals can be constructed using nested Sequence commands, as follows: Sequence[Sequence[Segment[Vertex[poly1, i], Vertex[poly1, j]], j, i + 2, n], i, 1, n - 2]. Note that Vertex[poly1, i] denotes the i-th vertex of poly1, counting from 1.)

 

The code for drawing the diagonals in his applet is:

Sequence[Sequence[Segment[Vertex[poly, i], Vertex[poly, j]], j, i + 1, n], i, 1, n - 1]

Wikispaces -- so compatible with GeoGebra

Wikispaces -- so compatible with GeoGebra | CEET Meet (Oct'2011): GeoGebra 101 ~ Linda Fahlberg Stojanovska | Scoop.it

~ Free for K-12 -- http://www.wikispaces.com/content/for/teachers

~ Free for higher ed. -- http://www.wikispaces.com/content/for/highered

 

The way I did it was to sign up for a wiki first (so I could use it right away) and then apply for the upgrade as per the instructions beneath the box on the free page.

GeoGebra Prim – a Simpler Version of GeoGebra for Younger Students

GeoGebra Prim – a Simpler Version of GeoGebra for Younger Students | CEET Meet (Oct'2011): GeoGebra 101 ~ Linda Fahlberg Stojanovska | Scoop.it

Geogebra Prim is just out and still in beta, but the few bloggers who've tried it seem to agree that it's more user-friendly and holds promise for working with younger kids or teachers who are less confident about using complex tech tools.

 

If you have time, spend a few minutes in the gallery at -- http://goo.gl/6oyfN. I'm not sure if the images were/could be created with Geogebra, but they're charming. My favourite are: Frankenslope; Mr. Slope's Brother, Mr. Slope, and Sistah Queen Slope.

Embed to PBworks | LFS & Nick Bennett

Ctrl+Shift+M copies the code to the clipboard in both versions, but in GGB 3.2 - you just don't get the feedback message. In PBworks, as a writer or editor, when editing a page select Insert > HTML/JavaScript, paste to code in the window, then Next and Insert Plugin, and Save. [If you do not see the GeoGebra applet I expect it is a firewall issue, blocking the Java code.]

 

There is an alternate way to get the Java code in the clipboard. This also works in 4.0RC. Nicholas (Nick) Bennett has posted a screen cast showing how at http://screencast.com/t/X4OZ5PaprFx9.  The first part of the video shows how to get the code. The latter part deals with embedding in wikispaces.

Equable Shapes & Animated Circles applets | Kathryn Peake

Equable Shapes & Animated Circles applets | Kathryn Peake | CEET Meet (Oct'2011): GeoGebra 101 ~ Linda Fahlberg Stojanovska | Scoop.it

"I watched a student working on this assignment (Equable Shapes) and had one of those 'Wow!' moments. The student was aged 15 and had only been using GeoGebra for a couple of hours, so it's quite an easy task to carry out. The 'Wow' moment comes when your drag the polygons so they lie on top of each other. I don't think you could 'see' the effect without dynamic geometry.

gmail_filter | LFS & Claire Thompson

If you use GMail you can set up a filter so that all messages from the forums go automatically into a folder or are deleted. What is nice about this is that once you set up the filter you can have it work retroactively--moving/deleting the many e-mails you may have already received.

To set up the filter do the following:

(1) In Gmail click on the settings icon (gear) in the top right corner and select 'Mail Settings'.
(2) On the settings page select the 'Filters' tab near the top of the page.
(3) Near the bottom of the page click on 'Create a new filter'
(4) Fill in the appropriate criteria--for this course I went to 'Has the words' and typed in GGB101 Forums. Since all of the messages from the forums have those words in the first part of the message. Also, this way you will be less likely to miss the very small number of messages that tell you that Linda has feedback on one of your assignments, or that someone has messaged you through the course.
(5) Next in that top area of the page click on the 'Test search' button. It will show you all of your current messages that will fit the criteria you've set.
(6) Then, in the same area click on the 'Next step' button.
(7) Now you choose the action that you want GMail to take when it filters out a GGB101 message. I chose 'Skip the Inbox (Archive) it'. You may choose to have the messages deleted. It's up to you.
(8) If you would like Gmail to perform the filter on messages already received then check the box that says 'Also apply filter to __ conversations below' (found near the bottom of where you create the filter).
(9) Finally, click the 'Create Filter' button.

Differentiation -- GeoGebra Event 2011 Slideshow | Kathryn Peake | CEET Meet (Oct'2011): GeoGebra 101 ~ Linda Fahlberg Stojanovska | Scoop.it

The 'create a face' task used in this workshop, is a great way of getting students, of all abilities, familiar with the tools and learning about reflection.

 

Second suggestion -- use GeoGebra to create a Fibonnaci Spiral and showing how website design uses this spiral (unknowingly - good designs just seem to fit naturally into the spiral) for visual effect.

Rule of Four | Claire Thompson

Rule of Four | Claire Thompson | CEET Meet (Oct'2011): GeoGebra 101 ~ Linda Fahlberg Stojanovska | Scoop.it

From the blog MathNotations (http://goo.gl/HZ5kE )
The Rule of Four suggests that a concept be presented
(a) Using natural language (words)
(b) Numerically (concrete examples, 'plugging in', use of data tables, etc.)
(c) Visually (e.g., using graphs, charts, concrete models)
(d) Symbolically (algebraical mode)

 

And from the Math Forum @ Drexel (http://goo.gl/Vl473 )
The "rule of four" phrase grew out of the calculus reform movement and the Harvard Calculus Consortium in particular. Deborah Hughes-Hallett, Andrew M. Gleason, et al. in the preface of their 1994 edition of "Calculus" write: Every topic should be presented geometrically, numerically, and algebraically. (The Rule of Three; p. vii). This was one of their basic guiding principles.

 

The Harvard textbook and other reform efforts have emphasized natural language
communication--reading, writing, speaking, and listening. So the verbal aspect of presentation has now been added to the rule of three to yield "The Rule of Four" in which very topic should be presented verbally, geometrically, numerically, and algebraically.

 

So in the examples Linda gave here I think the students are expected to solve the problems
- using words
- with algebra
- graphically
- and in a table

 

(Response from Geoff Roulet: "Being older than most I might be able to add a bit of history. I think the origins of the rule of 3/4 can be traced to the work of Jerome Bruner and his 1966 book -- Toward a Theory of Instruction."

GeoGebra Institute of NCERT, India - Activity-Measuring with a protractor | Praveen Chaurasia | CEET Meet (Oct'2011): GeoGebra 101 ~ Linda Fahlberg Stojanovska | Scoop.it

Many of the learning outcomes in the BC grade 6 math PLO's in Patterns and Relations and in Shape and Space could be addressed really well using GeoGebra. For example, this GeoGebra worksheet involves measuring angles with a protractor. The students get feedback right away as to whether they've measured the angle correctly.

This will give you a list of the steps you took to create an applet.  'Play' shows how you created your file. You can also change the order of the steps. This is a good way to stimulate organised thinking when you have students making their own applets.

 

Useful -- before Linda uploads applets to GGBtube, she checks this so that others who download the same file can follow what she did.
