Wigand Rathmann Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU), Department Mathematik, Erlangen, Germany, and Center of Mobile Learning with Digital Technology, University of Bayreuth, Bayreuth, Germany wigand.rathmann@fau.de Abstract We all know rivers and can imagine, to sit a boat enjoying sun and clouds at the sky and we are drifting along a river not using any paddel. Generated using Stable Diffusion Sounds like vacation and the rotation of the boat brings as the \(\operatorname{curl}\)-Operator. Thus we wake up back having vector fields in mind thinking about a boat became a single point and moving as a particle through the vector field along a curve \(k\) with an angle velocity induced by the fluid.

Andreas Maurischat RWTH Aachen University, Aachen, Germany maurischat@combi.rwth-aachen.de Abstract Besides the online course hm4mint.nrw , the consortium HM4mint has initiated a pool for electronic exercises including several graphical exercises. In this talk, we present examples of such exercises, we explain how you can import these exercises into your local LMS, and how you can adapt the exercises to your individual style.

Pedro A. García-Sánchez, joint work with Mattia Ducci, Ondřej Nečas, and Lukas Schölch Departamento de Álgebra and IMAG, University of Granada, E-18071, Spain pedro@ugr.es Abstract In this talk we will present Audiofunctions+, which is a web app designed to facilitate visually impaired students’ learning of mathematical functions. Audiofunctions+ allows users to interpret the shape of a function’s graph by listening to its sonification. The talk is suitable for both high school and university educators.

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 Teaching fundamental graph algorithms such as Kruskal’s minimum spanning tree, Dijkstra’s shortest path, and depth-first/breadth-first search often relies on static materials that do not adequately convey the interactive nature of algorithmic decision-making. This presentation describes a framework for creating interactive graph algorithm exercises using JSXGraph integrated with Moodle’s STACK question type system.

JSXGraph & LiaScript … a perfect Match name: Dr.-Ing. André Dietrich & Prof. Dr.-Ing. Sebastian Zug adress: TU Bergakademie Freiberg Bernhard-von-Cotta-Straße 2 09599 Freiberg abstract: Liascript is an extension for markdown with was especially developed as a language easy and dezentralized creation of interactive online courses, in short a language for OER. It add various features to markdown, which where previously missing, such as the integration of multimedia content, integration of Oembed sites, the execution of script-tags, animations in combination text to speech output to generate a mixture between screencast and interactive textbooks.

David Flenner College of Charleston Department of Mathematics 66 George St Charleston SC 29424 flennerdr@charleston.edu Abstract Bug-free code is something we all strive for, but there are bound to be unexpected situations that we don’t account for when developing a JSXGraph app for the first time. This talk will be a continuation of my presentation from the JSXGraph conference last year, which focused on best practices when first getting started with creating applications using JSXGraph.

Sebastian Tabares Amaya 2 Tian Jin Li Gong Da Xue Qing Nian Jiao Shi He Xue Zhe Gong Yu, Xi Qing Qu, Tian Jin Shi, China, 300387 me@syta.co Abstract Sr Smith is a powerful web application that reinvents the classic Smith Chart for the digital age. Built with the high-performance JSXGraph library and the intuitive JessieCode DSL, it provides RF engineers, professors and students with an interactive platform for circuit analysis and design, with a graphical experience similar to GeoGebra.

Audiofunctions+: exploring math functions through sonification Pedro A. García-Sánchez, joint work with Mattia Ducci, Ondřej Nečas, and Lukas Schölch Departamento de Álgebra and IMAG, University of Granada, E-18071, Spain Audiofunctions+ is a tool that facilitates the learning and teaching of mathematical functions for visually impaired students through sonification. It is one of the deliverables of the Erasmus+ Key Action 2 project SONAIRGRAPH, coordinated by the University of Turin, with participation from the Karlsruhe Institute of Technology (KIT), the GIS Community Association of Timisoara, and the Universities of Masaryk, Granada, and Valle d’Aosta.
