Content and Language Integrated Learning (CLIL) is an approach where students learn a subject and a second language at the same time. A science course, for example, can be taught to students in English and they will not only learn about science, but they will also gain relevant vocabulary and language skills.

It’s important to note that CLIL is not a means of simplifying content or reteaching something students already know in a new language. CLIL courses should truly integrate the language and content in order to be successful – and success is determined when both the subject matter and language is learned.

Who is CLIL for?

CLIL can work for students of any age, all the way from primary level to university and beyond. So long as the course content and language aims are designed with the students’ needs in mind, there is no limit as to who can benefit from this teaching approach. However, it is most commonly found in primary and secondary school contexts.

What are the main benefits of CLIL?

Many teachers see CLIL as a more natural way to learn a language; when a subject is taught in that language there is a concrete reason to learn both at the same time. And as students have a real context to learn the language in, they are often more motivated to do so, as they can only get the most of the content if they understand the language around it.

Moreover, being content focused, CLIL classes add an extra dimension to the class and engage students, which is especially advantageous in situations where students are unenthusiastic about learning a language.

CLIL also promotes a deeper level of assimilation, as students are repeatedly exposed to similar language and language functions, and they need to produce and recall information in their second language.

Furthermore, it has the advantage that multiple subjects can be taught in English, so that students’ exposure to the language is increased and their language acquisition is faster.

CLIL also encourages students to develop 21st century skills, including the ability to think critically, be creative, communicate and collaborate.

What are the challenges of CLIL?

As CLIL is subject-focused, language teachers may also have to develop their own knowledge of new subjects in order to teach effectively.

They must also structure classes carefully so that the students understand the content of the lesson, as well as the language through which the information is being conveyed.

And when it comes to classroom management, educators need to be very aware of individual student understanding and progress.

It’s therefore important to consistently concept check and scaffold the materials to be sure both the language and content are being learned.

How can you apply CLIL to your class?

It’s important to have a strategy in place when applying CLIL in your courses. One of the key things to remember is that the language and subject content are given equal weight and that it shouldn’t be treated as a language class nor a subject class simply taught in a foreign language.

According to Coyle’s 4Cs curriculum (1999), a successful CLIL class should include the following four elements:

  • Content – Progression in knowledge, skills and understanding related to specific elements of a defined curriculum
  • Communication – Using language to learn whilst learning to use language
  • Cognition – Developing thinking skills which link concept formation (abstract and concrete), understanding and language
  • Culture – Exposure to alternative perspectives and shared understandings, which deepen awareness of otherness and self

Using a number of frameworks can help you prepare your lessons and make sure activities are challenging yet achievable for your learners.

Bloom’s Taxonomy, for example, classifies learning objectives in education and puts skills in a hierarchy, from Lower Order Thinking Skills (LOTS) to Higher Order Thinking Skills (HOTS).

In the diagram below, you can see the levels increasing in complexity from the base up to the triangle’s peak.

The framework shows how different tasks relate to different levels of assimilation. It’s fairly intuitive, but applying this information to your lesson preparation is not always so straightforward.

That’s where the helpful Blooming Verbs list comes in. The following chart shows you how different verbs can correlate to the different stages in the taxonomy, allowing you to formulate questions and design activities that develop your CLIL classes in a logical way.

By using the verbs in the first column you’ll see how much they remember about a topic you have covered previously. Examples might include:

  • Can you name three different types of jungle animal?
  • Can you tell me how often a python eats food?
  • Can you describe what it’s like in the rainforest?

You can then do the same for the subsequent stages of the taxonomy.

The verb chart can also help you design a class project or series of activities that follow a logical sequence using the “Students will be able to…” (SWBAT) framework. This will help you set clear objectives and check progress towards the end of a class, series of classes or course.

Here’s an example of how you can develop a set of objectives using the verb columns to help you navigate Bloom’s Taxonomy:

  1. SWBAT name 10 different animals that live in the rainforest
  2. SWBAT predict what animals eat
  3. SWBAT complete a simple food chain
  4. SWBAT categorize animals into different classifications (mammal, reptile, fish etc.)
  5. SWBAT recommend ways to protect an endangered species
  6. SWBAT create a new habitat for an endangered species of their choice

In this way you will be able to scaffold your materials to ensure that your students are supported step by step while learning subject matter and achieving language learning objectives.

    How teachers can use the GSE for professional development

    By Fajarudin Akbar
    Reading time: 4.5 minutes

    As English teachers, we’re usually the ones helping others grow. We guide learners through challenges, celebrate their progress and push them to reach new heights. But what about our own growth? How do we, as educators, continue to develop and refine our practice?

    The Global Scale of English (GSE) is often seen as a tool for assessing students. However, in my experience, it can also be a powerful guide for teachers who want to become more intentional, reflective, and confident in their teaching. Here's how the GSE has helped me in my own journey as an English teacher and how it can support yours too.

    About the GSE

    The GSE is a proficiency scale developed by app. It measures English ability across four skills – listening, speaking, reading and writing – on a scale from 10 to 90. It’s aligned with the CEFR but offers more detailed learning objectives, which can be incredibly useful in diverse teaching contexts.

    I first encountered the GSE while exploring ways to better personalize learning objectives in my Business English classes. As a teacher in a non-formal education setting in Indonesia, I often work with students who don’t fit neatly into one CEFR level. I needed something more precise, more flexible, and more connected to real classroom practice. That’s when the GSE became a turning point.

    Reflecting on our teaching practice

    The GSE helped me pause and reflect. I started reading through the learning objectives and asking myself important questions. Were my lessons really aligned with what learners at this level needed? Was I challenging them just enough or too much?

    By using the GSE as a mirror, I began to see areas where I could improve. For example, I realized that, although I was confident teaching speaking skills, I wasn’t always giving enough attention to writing development. The GSE didn’t judge me. It simply showed me where I could grow.

    Planning with purpose

    One of the best things about the GSE is that it brings clarity to lesson planning. Instead of guessing whether an activity is suitable for a student’s level, I now check the GSE objectives. If I know a learner is at GSE 50 in speaking, I can design a role-play that matches that level of complexity. If another learner is at GSE 60, I can challenge them with more open-ended tasks.

    Planning becomes easier and more purposeful. I don’t just create lessons, I design learning experiences that truly meet students where they are.

    Collaborating with other teachers

    The GSE has also become a shared language for collaboration. When I run workshops or peer mentoring sessions, I often invite teachers to explore the GSE Toolkit together. We look at learning objectives, discuss how they apply to our learners, and brainstorm ways to adapt materials.

    These sessions are not just about theory: they’re energizing. Teachers leave with new ideas, renewed motivation and a clearer sense of how to bring their teaching to the next level.

    Getting started with the GSE

    If you’re curious about how to start using the GSE for your own growth, here are a few simple steps:

    • Visit the GSE Teacher Toolkit and explore the learning objectives for the skills and levels you teach.
    • Choose one or two objectives that resonate with you and reflect on whether your current lessons address them.
    • Try adapting a familiar activity to better align with a specific GSE range.
    • Use the GSE when planning peer observations or professional learning communities. It gives your discussions a clear focus.

    Case study from my classroom

    I once had a private Business English student preparing for a job interview. Her speaking skills were solid – around GSE 55 – but her writing was more limited, probably around GSE 45. Instead of giving her the same tasks across both skills, I personalized the lesson.

    For speaking, we practiced mock interviews using complex questions. For writing, I supported her with guided sentence frames for email writing. By targeting her actual levels, not just a general CEFR level, she improved faster and felt more confident.

    That experience reminded me that when we teach with clarity, learners respond with progress.

    Challenges and solutions

    Of course, using the GSE can feel overwhelming at first. There are many descriptors, and it can take time to get familiar with the scale. My advice is to start small: focus on one skill or one level. Also, use the Toolkit as a companion, not a checklist.

    Another challenge is integrating the GSE into existing materials, and this is where technology can help. I often use AI tools like ChatGPT to adjust or rewrite tasks so they better match specific GSE levels. This saves time and makes differentiation easier.

    Teachers deserve development too

    Teaching is a lifelong journey. The GSE doesn’t just support our students, it also supports us. It helps us reflect, plan, and collaborate more meaningfully. Most of all, it reminds us that our growth as teachers is just as important as the progress of our learners.

    If you’re looking for a simple, practical, and inspiring way to guide your professional development, give the GSE a try. It helped me grow, and I believe it can help you too.
