Critical thinking is a 21st century skill that has been around for thousands of years. There are records of Socrates using critical thinking skills in his teaching in 4th century BC Greece. In recent years though, critical thinking has again become more prominent in education.

What is critical thinking?

Critical thinking requires students to do more than remember and repeat information. Instead, it encourages them to analyze, examine, evaluate and use their problem-solving abilities through questioning, theorizing and rationalizing to have a deeper understanding of the world around them, both inside the classroom and beyond.

Why is critical thinking so important?

In the past, success in education was largely based on the ability to remember facts and figures. However, the skills which our students need today go further than memorization. With our rapidly evolving technology, the internet, and the bewildering amount of information online, it is essential that our students can use higher-order thinking skills to analyze and assess the information they are presented with.

How can you incorporate critical thinking into your classes?

Devising long-term goals

We all know the importance of looking ahead and planning for the future. We can encourage this skill in our students and directly relate it to their learning.

At the start of the course, take a moment to chat with each student individually and ask them to identify an objective for the first part of the year. You may like to brainstorm possible objectives as a class first, but it’s important for students to determine their own personal objectives, rather than imposing objectives on them.

During the first half of the year you can talk to each student about their progress and ask them to assess to what extent they’re achieving their goals.

The key point comes at the end of the semester when students evaluate their progress and set a new objective for the following one.

Analyzing

The ability to analyze options, risks and opinions will help your students in the future in many situations, including when they decide which course to take at university or which job to take.

You can practice this skill by providing students with relatable situations and asking them to analyze and compare the options.

For example:

Imagine you are taking a trip with some friends this summer. You have a number of different options and want to discuss them before finalizing your plans. Talk to a partner about the different trips and decide which would be best:

  • Traveling around Europe by train for a month ($1,000)
  • A weekend hiking and camping in the countryside ($200)
  • A weekend break in a big city, with shopping, sightseeing and museum trips ($500)
  • A week-long trip to the beach in an all-inclusive resort ($650)

Anticipating consequences

Students also need to have an awareness of the consequences of their actions; this is a skill which is transferable to making business decisions, as well as being important in their everyday lives.

To practice this skill, put students into small groups and give them the first part of a conditional sentence. One student completes the sentence and then the next student adds a consequence to that statement.

For example:

Student A: If I don’t study for my English exam, I won’t pass.

Student B: If I don’t pass my English exam, my parents won’t let me go out this weekend.

Student C: If I can’t go out this weekend, I’ll miss the big football match.

Student D: My coach won’t let me play next year if I miss the big match.

Rearranging the class menu

By giving students more responsibility and having them feel invested in the development of the lesson, they will be much more motivated to participate in the class.

Occasionally, let students discuss the content of the day’s class. Give them a list of tasks for the day, including how long each will take and allow them to discuss the order in which they’ll complete them. For larger classes, first have them do it in pairs or small groups and then vote as a whole class.

Write on the board:

  • Class discussion (5 minutes)

The following tasks can be done in the order you decide as a class. You have five minutes to discuss and arrange the tasks as you choose. Write them on the board in order when you’re ready.

  • Check homework (5 minutes)
  • Vocabulary review (10 minutes)
  • Vocabulary game (5 minutes)
  • Reading activity (15 minutes)
  • Grammar review game (5 minutes)
  • Speaking activity (10 minutes)

Take this one step further by asking your students to rate each activity out of 10 at the end of the class. That way, you’ll easily see which tasks they enjoy, helping you plan more engaging lessons in the future.

    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 ɫèAV. 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.

    Does progress in English slow as you get more advanced?

    By Ian Wood
    Reading time: 4 minutes

    Why does progression seem to slow down as an English learner moves from beginner to more advanced skills?

    The journey of learning English

    When presenting at ELT conferences, I often ask the audience – typically teachers and school administrators – “When you left home today, to start your journey here, did you know where you were going?” The audience invariably responds with a laugh and says yes, of course. I then ask, “Did you know roughly when you would arrive at your destination?” Again the answer is, of course, yes. “But what about your students on their English learning journey? Can they say the same?” At this point, the laughter stops.

    All too often English learners find themselves without a clear picture of the journey they are embarking on and the steps they will need to take to achieve their goals. We all share a fundamental need for orientation, and in a world of mobile phone GPS we take it for granted. Questions such as: Where am I? Where am I going? When will I get there? are answered instantly at the touch of a screen. If you’re driving along a motorway, you get a mileage sign every three miles.

    When they stop appearing regularly we soon feel uneasy. How often do English language learners see mileage signs counting down to their learning goal? Do they even have a specific goal?

    Am I there yet?

    The key thing about GPS is that it’s very precise. You can see your start point, where you are heading and tell, to the mile or kilometer, how long your journey will be. You can also get an estimated time of arrival to the minute. As Mike Mayor mentioned in his post about what it means to be fluent, the same can’t be said for understanding and measuring English proficiency. For several decades, the ELL industry got by with the terms ‘beginner’, ‘elementary’, ‘pre-intermediate’ and ‘advanced’ – even though there was no definition of what they meant, where they started and where they ended.

    The CEFR has become widely accepted as a measure of English proficiency, bringing an element of shared understanding of what it means to be at a particular level in English. However, the wide bands that make up the CEFR can result in a situation where learners start a course of study as B1 and, when they end the course, they are still within the B1 band. That doesn’t necessarily mean that their English skills haven’t improved – they might have developed substantially – but it’s just that the measurement system isn’t granular enough to pick up these improvements in proficiency.

    So here’s the first weakness in our English language GPS and one that’s well on the way to being remedied with the Global Scale of English (GSE). Because the GSE measures proficiency on a 10-90 scale across each of the four skills, students using assessment tools reporting on the GSE are able to see incremental progress in their skills even within a CEFR level. So we have the map for an English language GPS to be able to track location and plot the journey to the end goal.

    ‘The intermediate plateau’

    When it comes to pinpointing how long it’s going to take to reach that goal, we need to factor in the fact that the amount of effort it takes to improve your English increases as you become more proficient. Although the bands in the CEFR are approximately the same width, the law of diminishing returns means that the better your English is to begin with, the harder it is to make further progress – and the harder it is to feel that progress is being made.

    That’s why many an English language-learning journey gets abandoned on the intermediate plateau. With no sense of progression or a tangible, achievable goal on the horizon, the learner can become disoriented and demoralised.

    To draw another travel analogy, when you climb 100 meters up a mountain at 5,000 meters above sea level the effort required is greater than when you climb 100 meters of gentle slope down in the foothills. It’s exactly the same 100 meter distance, it’s just that those hundred 100 meters require progressively more effort the higher up you are, and the steeper the slope. So, how do we keep learners motivated as they pass through the intermediate plateau?

    Education, effort and motivation

    We have a number of tools available to keep learners on track as they start to experience the law of diminishing returns. We can show every bit of progress they are making using tools that capture incremental improvements in ability. We can also provide new content that challenges the learner in a way that’s realistic.

    Setting unrealistic expectations and promising outcomes that aren’t deliverable is hugely demotivating for the learner. It also has a negative impact on teachers – it’s hard to feel job satisfaction when your students are feeling increasingly frustrated by their apparent lack of progress.

    Big data is providing a growing bank of information. In the long term this will deliver a much more precise estimate of effort required to reach higher levels of proficiency, even down to a recommendation of the hours required to go from A to B and how those hours are best invested. That way, learners and teachers alike would be able to see where they are now, where they want to be and a path to get there. It’s a fully functioning English language learning GPS system, if you like.
