Advanced JSXGraph I + II

Alfred Wassermann University of Bayreuth, Germany Workshop In this workshop we will look at various topics of a more advanced flavour. The following topics are planned so far: dependent / dynamic elements using functions dynamic attributes set attribute values MathJax Include HTML Bidirectional communication with DOM Constructing with loops JessieCode Construction dumps For part II of the workshop we are open to suggestions which topics to discuss.

Extending JSXGraph with WebAssembly

Michael Gerhäuser Method Park, Germany WebAssembly is an open standard for executing non-JavaScript programs inside a web browser. We will explore the possibilities this relatively new technology opens up for JSXGraph developers, content creators and users.

Utilizing JSXGraph to Implement John Conway's Game of Life

Leslie Wong Shenzhen University, Guangdong, China Motivation Game of Life is a renowned cellular automation model devised by John Conway, a mathematician at Cambridge. However, when searching “game of life John Conway” at Google Images, it is hard to spot an elegant and appealing implementation. Therefore, as I came across the wonderful JavaScript animation library JSXGraph by chance and was obsessed with its UI, the aspiration to implement game of life by my own was aroused.

JSXGraph and the Moodle Plug-in Formulas

Andreas Walter, M.Ed. Forschungsstelle für mobiles Lernen mit digitalen Medien, University of Bayreuth, D-95440 Bayreuth, Germany Marc Bernat Martinez Alemany BonNouEdu, ITEMS project partner, Spain Abstract Homeschooling and still tangible geometry experience! This is possible with the JSXGraph Moodle filter. It enables the integration of JSXGraph constructions almost everywhere where HTML elements are used in Moodle. Moodle users can view the constructions, change them with their mouse or fingers and thus experience geometry up close - no matter where they are.

Spirolaterals with the turtle

Alain Busser Teacher (math and CS) at Lycée Roland-Garros, Le Tampon IREMI La Réunion Abstract Professor Frank C Odds, a world leading authority in medical mycology, devised in the 1960s, while he was a student, the beautiful geometric patterns known as spirolaterals: For a spirolateral, two parameters are required: an angle (the rotation of the turtle at each step) an number of iterations (or the length of a list of distances at which the turtle travels) A scientific experiment requires that one repeats the trials while modifying the values of the parameters.

Authoring STACK questions combined with JSXGraph

Miko Karjalainen Aalto University, Finland miko.karjalainen@aalto.fi, Workshop The workshop focuses on how to author more advanced exercises with the STACK system utilizing JSXGraph. The main learning goals are the inclusion of JSXGraph within STACK, how user input can be read and assessed from the graphs and how one can further employ randomly generated question variables in the exercises. In order to participate in this workshop it is advisable to have some preliminary knowledge of the STACK system.

Automatically assessed STACK exercises in Mathematics

Pekka Alestalo Department of Mathematics and Systems Analysis Aalto University, Finland The presentation will be an elementary introduction to creating Math exercises in STACK (= the System for Teaching and Assessment using a Computer algebra Kernel). STACK system offers random generation of questions with wide variety of input types, e.g. mathematical expressions so that the options are not limited to multiple choice. The student’s input is automatically checked with Maxima program so that answers algebraically equivalent to the correct one are accepted.

Concept for automatic assessment of free body diagrams

Martin Kraska Technische Hochschule Brandenburg, University of Applied Sciences, Magdeburger Str. 50, 14770 Brandenburg an der Havel, Germany Abstract Under the conditions of heterogeneous entry skills of our students we have to augment classical synchronous teaching, be it face-to-face or online, by asynchronous approaches for self-paced individual learning and training. One of these approaches is to provide online exercises with automatic instantaneous feedback. Therefore, STACK (a system for assessment of mathematics based on a computer algebra) based homework assignments with and without grading stake have been used in the past.

CONwiB Lines - A joint venture between Geometry and Block-based Programming

Dr. Andreas Kirsche Kirchgasse 1, 99310 Arnstadt, Germany Abstract Construction is a fundamental activity in geometry class. The drafting of construction descriptions supports the mental operation and last but not least makes a contribution to math conception. However, construction descriptions are only effective if they are generated before the construction process. The CONwiB project was launched to maintain this order. The applications of this project ask the user to create a constrution description in first place.
