[LON-CAPA-users] background image in geogebra

[Carl Lira]

Thank you. Until your help I was unaware of the option to embed custom
problems in loncapa. Bummer that they removed the option to export to html.
I don't like assignments on one server that are dependent on another server
working.

A follow up question. Your example shows a single submission. Can multiple
parts be constructed where students complete one part of a graphical
construction and then move on to a second part that they add to the graph?
How would you suggest I approach that type of multiple part problem? To be
specific, I would like to guide students to first find a particular point
and then draw a line through that point and then add a second line with a
different slope through the same point, so they end up with a distorted X,
where the slope and endpoints of each leg are important. 

Carl

Carl,

I wanted to mention some things that I wish I'd known (and didn't pop up on
Google right away for me):

Since the videos were made, GeoGebra removed the option to export as a
webpage.  This option is still in the menu, but it will just make you upload
it to GeoGebraTube.  Instead, I uploaded the GeoGebra worksheet to
GeoGebraTube (tube.geogebra.org) and told LON-CAPA where to find the
worksheet.  Once the worksheet is uploaded to GeoGebraTube, to embed the
applet in LON-CAPA, I used the second method on this page:

https://www.geogebra.org/manual/en/Reference:Applet_Embedding

I also found the source for this page helpful:

http://archive.geogebra.org/source/program/applet/geogebra_applet_javascript
_test.htm

And these were very helpful:

http://www.geogebra.org/manual/en/Reference:JavaScript
http://www.geogebra.org/manual/en/Reference:Applet_Parameters

Good luck,
Jacob

Thank you for the links! I will study these.

Carl,

I just realized that you might not have been talking about a "custom" applet
(http://www.lon-capa.org/geogebraTutorial.html; though I had to modify the
procedure a little to get it to work).  You can insert an image into a
"custom" applet.

Is it possible to insert a background image in goegebra loncapa problems? I
can think of some problems where I would like students to draw on top a
background diagram. The background diagrams are complicated enough that it
is currently impractical to generate them with a simple function (phase
diagrams).

Thanks,

Carl Lira
