The document discusses how the theory of learning through discovery relates to language learning. It states that learning through discovery allows pupils to explore and experiment, encouraging new understandings while allowing learners of different cognitive levels to work together. It also notes that children develop at different rates, so teachers must arrange classroom activities for individual students and groups rather than the whole class. An example classroom activity described is making a fruit salad, where students are given instructions, work in groups to carry out the steps, and discuss their experiences.
