The integration allows .LRN teachers to seamlessly add LAMS lessons to their .LRN courses. These lessons are sequences of Learning Activities that teachers design using the LAMS drag-and-drop authoring environment.

LAMS2 is quite different from its version 1 release, which it was also integrated with .LRN. For more info, hit the LAMS wiki docs.

I have set up a LAMS2 - .LRN 2.3.1 demo server for those of you who might want to give it a spin.

Also, here is a two minute animation on how it all works.

More info, source and tech docs, available in the LAMS2 .LRN wiki page.
