1. The document describes a case study where researchers redesigned an online reading course using van Merriënboer's Ten Steps to Complex Learning model.
2. They analyzed the original course goals and designed new learning tasks, sequenced them into task classes, and developed supportive materials like annotated readings.
3. Challenges included defining learning goals and tasks, sequencing tasks, and identifying key ideas from readings. The redesigned course incorporated knowledge checks and opportunities for critique.
