Coding is done using the LIDO, SDI, and QTI systems. However, some of the videos will not have SDI coding since that instrument can only be used in whole group instruction. Also some of the files are missing QTI coding because they were added late in the project and those RAs have graduated.

The LIDO coding manual is available here.
