Abstract
Researching the sharing of learning designs is a well-established domain within the technology-enhanced learning research community. However, until now tools supporting educational modelling languages such as IMS Learning Design have reached a wide adoption in today's school practice. Following a design science research methodology we report on the design, implementation, and evaluation of a novel tool referred to as "Composer". The Composer supports the design of learning activities and has been developed according to design principles such as (a) interoperability between design-time and run-time systems based on the W3C Widget Standard, (b) inclusion of artefact types beyond content such as tools, people and events, (c) a user-friendly authoring environment. A first evaluation of the proof-of-concept implementation suggests that the tool is easy-to-use and provides added value for teachers when it comes to reflecting about the design of learning activities.
