JSXGraph in CTM Assessment: Lightweight Interactive Mathematics with AI Support

Andrey Chesnokov Department of Mathematical Sciences, Norwegian University of Science and Technology, 7491 Trondheim, Norway andrey.chesnokov@ntnu.no Abstract The principle of putting the “book inside the quiz,” promoted by the STACK community , brings explanations, examples and assessed practice into a continuous learning experience. This talk presents CTM Assessment as a complementary, lightweight route towards this goal, particularly for teachers and institutions with limited access to dedicated hosting or technical support.

JSXGraph extension for Quarto

Carsten Miller Center for Mobile Learning with Digital Technology, University of Bayreuth, Germany carsten.miller@uni-bayreuth.de Abstract This live demo will introduce the JSXGraph extension for Quarto , which allows interactive mathematical visualisations to be included directly within Quarto documents. It will demonstrate how to add a JSXGraph board and explore options for controlling its size and appearance, as well as displaying the source code alongside the graphic. It will also demonstrate how to select interactive HTML output or static SVG export for formats such as PDF and Word.

JSXGraph Geography: Maps and Globes as Constructions

Carsten Miller Center for Mobile Learning with Digital Technology, University of Bayreuth, Germany carsten.miller@uni-bayreuth.de Abstract Every flat world map distorts something. The property that is preserved – area, angle or distance – is a choice that is rarely made explicit to the reader. In September 2026, the UN General Assembly addressed this issue in Resolution A/RES/80/307. The resolution recommended equal-area projections, such as Equal Earth, for situations where relative size is important.

"Area" selection for solving graphically modelled maths problems using Moodle/STACK/JSXGraph

Leif Bremer and Karin Landenfeld Hamburg University of Applied Sciences, Germany Karin.Landenfeld@haw-hamburg.de Keywords: Digital exercises, digital assessment, mathematics, STACK Abstract Digital exercises enable students to practise the skills learnt in lectures and demonstrate their mastery in appropriate digital examinations at the end of the semester. In addition to knowledge-based questions and calculation tasks, exercises that test conceptual understanding – particularly interrelationships – are an important component of such assessments. Interrelationships and concepts can be learnt very effectively through the use of graphical representations.

Avoiding the human translation gap (and then some)

Charles Grisar charles.grisar@gmail.com Abstract Connecting mathematics to an interactive graph often requires translating it into program code. That translation introduces opportunities for error: a single missing factor in a Fourier series can still produce a convincing plot, just the wrong one. This talk presents 4ier, a system that connects mathematical notation to interactive JSXGraph visualisations while retaining the conditions under which its results apply. Starting from LaTeX, 4ier builds a structured expression tree.

From Chalkboard to Code: Exploring JSXGraph’s sketchCurve

Wigand Rathmann Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU), Department Mathematik, Cauerstraße 11, 91058 Erlangen, Germany and University of Bayreuth, Germany wigand.rathmann@fau.de Abstract JSXGraph’s new sketchCurve object bridges the gap between analog and digital mathematics. By enabling hand-drawn sketches to be digitized, it unlocks creative possibilities for teaching, presenting, and assessing mathematical concepts. In traditional lectures, sketches are indispensable—whether for illustrating function graphs or highlighting critical points like extrema. sketchCurve now brings this intuitive, pen-based approach to the digital world.

Interactive Graph Theory Exercises with JSXGraph and Moodle STACK

Frauke Sprengel Department of Computer Science, Faculty IV - Business and Computer Science, Hannover University of Applied Sciences and Arts, Hannover, Germany frauke.sprengel@hs-hannover.de Abstract Graph theory is a core topic in mathematics courses for computer science, covering concepts such as directed and undirected graphs, trees and spanning trees, connectivity, and weighted graphs, as well as algorithms operating on them. Understanding this material requires more than reading definitions and studying worked examples: students need to construct graphs with prescribed properties themselves and need to carry out algorithms step by step on concrete instances.

JSXGraph Use in Doenet

David Flenner College of Charleston, Department of Mathematics, 66 George St, Charleston SC 29424 flennerdr@cofc.edu Abstract This discussion will introduce the audience to a product called Doenet. Doenet is a resource instructors can use to create interactive assignment webpages for their students, featuring a variety of components. A particularly attractive aspect of these webpages is that they are created in an accessible manner, ensuring that any content is compatible with screen reader software and permitting equitable access to assignments for all students.

lia-coordinate in the Classroom: From Interactive Mathematics Tasks to Reusable OER LiaScript Courses

Martin Lommatzsch Geschwister-Scholl-Gymnasium Freiberg, Germany m.lommatzsch@gsg-freiberg.lernsax.de Abstract How can teachers turn dynamic geometry from a visual demonstration into an interactive, assessable, and reusable learning task without writing extensive JavaScript? This talk presents lia-coordinate, a LiaScript template built on JSXGraph, and explores its use in classroom mathematics from both the learner’s and the teacher’s perspective. Practical examples demonstrate how learners can place points, reconstruct graphs, construct geometric figures, and receive automatic feedback on coordinates, lengths, angles, areas, perimeters, and combined geometric conditions.
