Th1s study investigates the terms, dialogue, structure and active learning in Open Distance learning texts in aa constructivist and problem-solving approach. In-text activities are imbedded in selfstudy texts. Their construct is validated against appropriate instructional design and learning theories for active learning. A course team developed, implemented and piloted a Unisa course for mathematics teachers in South Africa. The results describe their professional development through action learning. The Tornado-approach affects teams in organisations. A team used participatory action research and action learning with rich descriptions to document the longitudinal case study of four action research cycles over eight years. Qualitative research involved a literature survey, notes, portfolios, mindmaps, letters, interviews, document analyses, and assessment results. Our action research demonstrates ways to implement a post-modern learning design in an industrialized· institution. The researcher applies action learning in professional development, in team management, and suggests models for successful/unsuccessful teams (tornado-effect).
