The document describes a Teaching and Learning Cycle (TLC) framework for systematically scaffolding students' language and literacy development. The TLC is based on Vygotsky's zone of proximal development and Bruner's concept of scaffolding. It involves a 4-step process: 1) Setting the context, 2) Modelling, 3) Joint construction, and 4) Independent construction. Teachers use this cycle to plan units where they build students' topic knowledge, explicitly teach text structures and language features, and provide support and feedback to help students independently construct texts in the target genre. The TLC provides a rationale and framework for sequencing teaching and learning activities to focus on language learning and scaffold students towards independence.
