This research report discusses several efforts which were undertaken to assist PLANIT (Programming Language for Interactive Teaching) authors in the writing of team lesson scenarios. It also describes and illustrates the assistance given to two such authors who were engaged in the development of computer assisted instruction for training teams of tactical data system users. The text of the document first sets forth a definition of team training which is meant to be a frame of reference for the authoring features later discussed. After this, several specific authoring strategies are presented which enabled the kind of lesson presentation desired by the authors. A demonstration lesson is described which was developed to quickly show PLANIT team training concepts. The rationale for the lesson is described in the text and the lesson itself is appended as well as two other products of the effort: a set of recommended modifications to the PLANIT language designed to simplify the team authoring process, and a detailed set of authoring guidelines to help conventional PLANIT authors become "team" authors.
