Results of Recent Work

These are some results if my actual work. They are provided for free as Open Educational Resources (OER) under a CC-BY-NC license. To a large extent, these are aggregations of OER provided by others. They showcase what becomes possible when engaged teachers collaborate with engaged software developers. These are fit for real life classroom usage and adaptation by non- technically minded teachers.

MathTrek++

Together with colleagues from Sweden, the UK and Austria I started elaborating a question-centered, socratic, approach to education. In this approach, students are encouraged to develop hypothesis and to evaluate them critically. A series of interactive documents demonstrates this for models of the atmosphere.

Notebook Player

The Notebook Player converts Jupyter Notebooks into interactive web pages the code of which can be edited and executed in SageCells. These pages require neither login nor installation of any software. Their user interface can be fully customized to meet the students‘ needs.

COVID-19 Analysis

The COVID-19 pandemic is an excellent opportunity for a reality check of mathematical epidemiologic models, as in theseinteractive documents. Mathematical models describing the COVID-19 in Germany Mathematics for the Corona Virus Exponential Regression in Ocatve Comparing the COVID-19 Development in any 2 Countries

SageCell Doctor

The transition from using Python 2 to Python 3 as programming language broke some code used in the SageCell online computer algebra system. The SageCell Doctor Page collects broken code examples and - where available - recommendations to correct code errors.

Jupyter Notebooks for Math Teaching

A summary of information (in German) on Jupyter notebooks - what they are, how they can be dited, how they can be read and links to some sample notebooks on linear combinations, , linear approximations and 3 notebooks studying what happens when a 4-dimensional object passes through our 3-dimensional world.

Survey on Online Math Test Systems

Supported by many colleagues from academia and industry I compiled a survey on 11 online Math test systems. It is intended to support teachers, support units and system administrators in comparing the systems and selecting the most appropriate for their use cases. Besides basic data it provides implementatations of 5 types of math questions, from the student‘s and from the author‘s perspective. Test-Analyzer A web site that analyzes results of tests. After importing a csv file of test results, the app detects problematic questions (for example: Where do the best students fail?) and provides advice how problems might be corrected. A graphical view of score distributions is included. GDPR safe: No data are sent to the server; all calculations are done in the web browser. Currently the Open Source learning management systems IMathAS and ILIAS are supported. The system has been developed in Javascript using Vue.. More Products

The NetMath Web Site

The NetMath web site (in German) is the public face of the NetMath community. NetMath helps its members to utilize digital media in teaching Math and Engineering.

The NetMath Search

Engine

The NetMath search engine lets you find and access free resources from the NetMath community (mostly in German) with a single click.

The IMathAS Math Test

System

IMathAS is an Open Source Math test system developed by David Lippman. I provide teacher support for its users as part of my work for the Virtual Campus Rhineland-Palatinate.
