What is Learning Design Language

IMS learning design (IMSLD) is an open standard that can be used to specify a wide range of pedagogical strategies in computer-interpretable models. Such models then can be played in any learning design (LD) compatible execution environment to support teachers and students to conduct online teaching–learning. This chapter introduces the basic knowledge required to effectively use LD. First of all, we present fundamental principles behind LD. Then, we introduce main concepts and their relations in LD and discuss some technical issues about how to make a learning design executable in a computer-based environment. Finally, how to model learning designs using LD is explained through demonstrating the whole procedure to model a use case in Extensible Markup Language (XML). We expect that the readers of this chapter can apply LD to create simple learning designs and understand learning designs with sophisticated features.
