Projects

Toolbox Lehrerbildung
Toolbox Lehrerbildung

A multidisciplinary learning platform for student teachers. It juxtaposes topics from educational science, psychology, didactics, and the science of STEM subjects. To illustrate how they interact, we use staged lesson videos.

Stroke-based Handwriting Recognition
Stroke-based Handwriting Recognition

My doctoral dissertation; in which I created a descriptive geometry-focussed handwriting recognition algorithm. The goal was to use a minimal training data set and still have a robust enough product, which can be used by sixth graders in the ALICE iBook (see below).

ALICE:fractions
ALICE:fractions

A digital, interactive schoolbook for sixth graders about fractions. We designed the book with a focus on the geometry of fractions in mind to foster an intuitive understanding of them. We also conducted two large-scale studies and distilled our findings into three PhD theses.

Sum And Product
Sum And Product

A YouTube channel about mathematics, and maybe some computer science and other STEM topics. Only one video, so, let's see where this is going...

Mathina
Mathina

An interactive mathematical fairy tale for young learners. My part was created in cooperation with Imaginary and focuses on teaching the concepts of coordinates and curves.

CindyJS
CindyJS

A dynamic geometry software that runs in the browser. After using it daily for many years, I finally started to look under the hood, trying to contribute to the codebase.

Egdod
Egdod

A library for the dynamic geometry software CindyJS with an emphasis on an animation module and UI elements. Basically, a collection of all the auxiliary code I wrote over the last few years and which I copy-pasted from one project to the next. Might be unusable by anyone who isn't me…

Doomsday Trainer
Doomsday Trainer

In 1973, John Conway developed a method to quickly compute the weekday of any given date. I created an Android app to practise this algorithm on the go. It's not particularly fancy, but it does its job and keeps track of a few interesting statistics. If you're interested in practising Conway's method, give it a look!

Bavarian Go Association
Bavarian Go Association

Go is an ancient Asian board game which has a growing fan base in the west. German Go players are organised in 16 associations. I'm a member of the board of the Bavarian Go Association and I work there as treasurer and membership administrator.
