This teaching and learning cycle is useful for teachers in planning a lesson. It helps you think through how to approach teaching a text or resource and how learners may experience the learning process progressively working up to independent construction. It was first developed by Rothery as part of a literacy teaching project in Sydney. For more comprehensive information about this pedagogy see this online paper at Design Literacy Pedagogy (pdf).
I’ve used this as the basis for developing new workflow lessons which integrate elearning tools, social media tools and ESL activities.
