The good news about formulating a strong lesson plan for a Content and Language Integrated Learning (CLIL) class is that it will contain many of the same features of a good lesson plan for any class. That is, it will include transitions from and to the previous class and the next one, it will warm students up to the day’s lesson in an engaging way, it will present new material and recycle familiar material, it will include some ways to assess progress during the class, and it will be flexible enough to account for classes that move slower or more quickly than you had anticipated.
What’s important about CLIL lesson plans, though, is that you include both subject area content and language points so that you derive the full benefits of a CLIL approach. If you try to wing it, you might wind up concentrating on one area to the detriment of the other.
The key elements of CLIL lesson plans are:
Content – Most teachers find it easiest to start by considering the content. What knowledge – that is, what subject area material – do you want to transmit? How are you going to present it – through an article, a video, a demonstration, a discussion, or an experiment?
It can be helpful when planning to finish sentences such as I want my students to be able to/At the end of the class, they should know… If you have a cooperating content area teacher at your institution, meet with that person in advance to go over your goals and see how they interact with theirs.
Language – Once you have the content pinned down, you can pick out the necessary language and communication skills that students will need to engage with the material. For example, these could include: specialized vocabulary, functional phrases and collocations, pronunciation or intonation practice, grammatical structures, features of text organization.
You’ll find these linguistic features in the texts that you present, but also in the language that students need to complete tasks. Imagine yourself as a student carrying out a task. What will you say? What will you write? Then, determine if you’ll need to teach any of this language to your class before presenting students with the task.
