From CRUNCH - learning analytics
Jump to: navigation, search

Welcome to The cRunch Tutorials!

This hub of tutorials was created by the project 'Technology-Enhanced Learning Living-lab for Manufacturing Environments' (TELL-ME). It was introduced originally in support of the 2013 MOOC on Learning Analytics and Knowledge (LAK'13). It has been extended for a tutorial given to the doctoral school in May 2013 at the Institute for Business Informatics of the Goethe University of Frankfurt, Germany, and it was grown further for the workshop at the Joint European Summer School in Technology-Enhanced Learning (JTEL-SS, May 2013, Cyprus).

Getting started

Open Source communities have started to invest heavily into the development of learning analytics. One particularly rewarding example of that is the R community, which is centred in on statistics and exploratory data programming.

Within this tutorial, we will be taking a closer look on R and we will be using cRunch and Rstudio for it. cRunch is both infrastructure and community platform for computationally-intense learning analytics, supporting researchers in investigating big data generated in the co-construction of knowledge. cRunch runs a web-based, exploratory data mash-up environment for R (Rstudio, also available as desktop software) and provides sharing facilities for data, scripts, and reports.

You best know basics about scripting in any other programming language and you should be familiar with simple data analysis as created with basic Excel knowledge.

To get things rolling:

The tutorials (basics)

In the first section you will find a few rather generic introductory tutorials and how-to's. If you are not familiar with R (or similar languages), then the first one is highly recommended. If you want to become more familiar with the web studio environment (and cRunch's facilities to create reports, release open data, etc.) then the other ones listed are the thing to go for.

The tutorials (learning analytics)

The Learning Analytics specific tutorials follow below. This set of online tutorials demonstrates how to do very particular types of Learning Analytics.
