LernTools - Tools for digital teaching with a focus on privacy

There are many good tools on the internet that support collaborative learning - but unfortunately they often use trackers or involve resources from third parties. This situation was the starting point for developing simple tools that do not process any personal data of students and do not track them or their actions.

Main menu

Components of the application

The application is strictly modularized, where the following modules are available in separate repositories:

  • abcd: Interactive quiz, technically spoken an simple audio response system (a bit like kahoot)
  • ideas: Collaborative online brainstorming for groups of students (a bit like padlet)
  • survey: Survey tool - create simple surveys with three question types (yes / no, agreement, free text)
  • projector: Online projector - allow students to transfer photos to the lecturer's browser.
  • tex: Tex Trainer - exercise the TeX syntax for math formulas
  • about: About Information - add personalized information to your instance

Students in generall do not have to register, all apps can be accessed vi qr-code or link + ticket.

Technical basics

The learning tools are a "full-stack Javascript" application. This means that only Javascript is used on both the server and the client. Unfortunately, that means that the application won't run in the classic LAMP stack - you will need a MEVN stack (MongoDB - Express - Vue - Nodejs) instead. The advantage is that as a developer you only have to master one programming language and modern web technologies (such as web sockets) can be used directly and easily.

The application bases on the following components:

  • Nodejs: Runtime environment for server-side Javascript (see also https://nodejs.org/en/)
  • Express: Server-side framework for developing web applications using Javascript (see also https://expressjs.com/).
  • Vue: Cient-side JS-framework, similar to Angular or React (currently Version 2)
  • MongoDB: Non-relational database, which can be used to save documents at a piece (without paying attention to the classical normal forms ...). This simplifies the development significantly, since objects can be stored directly. The framework Mongoose is used to connect nodejs and monbgodb.
  • Bootstrap: Extensive CSS (and Javascript) framework, which allows easy design of ergonomic and responsive surfaces.
  • katex: Representing mathematical formulas (TeX syntax) in the browser (via Javascript)
