In the document, the author compares and contrasts lesson planning for teaching English as a foreign language (EFL) versus content and language integrated learning (CLIL). For EFL planning, vocabulary is strictly structured, whereas CLIL planning allows for unlimited vocabulary introduced by students. The main difference is that EFL focuses on learning specific vocabulary and structures, while CLIL prioritizes developing cognitive and cultural skills through student-centered learning. CLIL planning is also designed for students who have experience with the CLIL methodology and a wider vocabulary base from studying in a CLIL school system.
