#jsxgraph — Public Fediverse posts

Ich habe #jsxgraph dafür benutzt und, dass ich es am Ende hinbekommen habe, spricht für #jsxgraph, aber wenn es das als Option gäbe, wäre super (@unibayreuth ;-))
So ist es echt anspruchsvoll und da für S:S alles ja aussehen soll, wie am Ende in der Prüfung ist das echt schwer. Und ich bin noch nicht an der Stelle, wo man Punkte von Vektoren unterscheiden und eingeben muss. Dass in der Schule Vektoren mit Pfeil geschrieben werden hilft auch nicht gerade😅
Also das mit der Digitalisierung ist 🫠

Hat jemand hier schon mal per #STACK + #JSXGraph oder #Geogebra, eine Aufgabe erstellt für #Moodle Tests, in der man graphisch eine Vektoraddition bzw. Kräfteaddition konstruieren musste per Parallelogramm?

Ich würde gerne sehen, wie das angegangen wurde, weil ich gerne ausreizen würde was möglich ist mit STACK+ Grafik.

Found out about this at the #Moodle #STACKmath conference in #Durham. It is a set of pre-built items for creating STACK questions with #JSXGraph. Have not tried it yet, can anyone else commment?

Yesterday was day 1 of the 3 day International Meeting of the STACK community.

It was inspiring to be around so many smart people working on improving #maths education. There was good coverage of the use of JSXGraph for creating questions with graphics that students can interact with . Recent developments in Large Language Models and #AI have made it much easier to create the #Javascript code required for #JSXGraph .

🚀 #hyperbook v0.51.0 is out!
You can now add interactive geometry, function plots, charts & data visualizations with #jsxgraph 📊📐

You can see the code that runs the #moodle #jsxGraph #STACK #maths question types I posted yesterday here

https://github.com/marcusgreen/moodle-qtype_stack/tree/catalyst_library/samplequestions/stacklibrary/Catalyst/jsxgraph

There is plenty of scope for improvement and similar question types so I welcome any ideas and feedback.

The code is here

I just voted Vscode, though I am actually running a close relative vscodium

And at the moment I am using it for #jsxgraph for the #stack quesiton type running in #moodle... (possibly more than you wanted to know...)

There's a new release of #JSXGraph - https://jsxgraph.org/wp/2024-01-26-release-of-version-1.7.0/.
Among other things, it adds an 'implicit curve' object.

I thought I'd try it out in @numbas, then realised that the way Numbas evaluates expressions is far too slow for this kind of numerical approximation - it does a lot of dynamic type-checking that takes a long time.

So I nerdsniped myself into writing a routine to take a Numbas JME expression and make a function which is as close to native JS as I can get. It works on all of the operations that you'd expect a student to use, since those have plain-JS implementations. There's just the control flow stuff and things to do with collections that need the whole JME system.

And now that I've done that, I have a nice, real-time interactive function plotter!
I've made a demo question at https://numbas.mathcentre.ac.uk/question/152679/give-a-function-defining-an-implicit-curve/preview/

It's really simple to implement in Numbas: you set up a JSXGraph diagram, and fill in the function parameter of the implicit curve object with the expression the student typed. Just a few lines of code. Nice!

Earlier this week I was using #JSXGraph and wanted a slider to snap to 0 when it was close.
Yesterday I wrote the code to enable that, and this morning it was merged in!

In other news, the JSXGraph conference #JSXGraphConf2023 is next week: http://jsxgraph.org/conf2023/

I've just noticed that the #JSXGraph team are revamping their collection of examples: http://jsxgraph.org/share/. This is very welcome! The old wiki was very hard to use, and hard to tell if the example you wanted was there or not.
