It's 6 AM on a Monday morning. Ms. Lopez wakes up early to prepare for the day ahead. She spends the morning reviewing lesson plans, making sure everything is ready for her students. By lunchtime, she is preparing for the afternoon, grabbing a quick bite between classes... but it doesn’t stop there. The school day finishes but Ms. Lopez stays late marking assignments. Finally, on Sunday night, she sits at her kitchen table, surrounded by papers, course books and lesson plans.

Does this sound familiar? You are not alone.

The challenge teachers face

In 2024, ÃÛÌÒapp research found thatÌý76% of teachers spend at least one hour of their personal time on lesson planning each week, with 43% spending more than three hours. This is a lot of time that could be spent on other important tasks. Teachers need a solution that helps them plan lessons fast, is connected to their course books and is built by learning experts.

Meet Smart Lesson Generator

Smart Lesson Generator is an AI tool that cuts the time that teachers spend on lesson planning.ÌýIt uses AI to create activities in seconds based on the learning objectives, topics and vocabulary you plan to use.

Whether you're using ÃÛÌÒapp courseware or designing your own lessons, this tool ensures that the materials match your curriculum and your students' skill levels.

How it works

There are key steps to generate activities with Smart Lesson Generator:

1. Selection: Teachers choose the type of activity they want to generate, such as a Lesson Hook, Vocabulary, Grammar, Conversation Starter, Reading Comprehension, or Exit Ticket. They then specify whether they are using ÃÛÌÒapp courseware or a custom lesson plan. This flexibility allows teachers to tailor their approach to suit their unique classroom dynamics.

2. Generation: AI generates activities using a Large Language Model (LLM) based on the teacher's input. The content is then filtered through GSE checks to ensure it is at the appropriate level. This step is crucial as it ensures that the generated material is not only relevant but also pedagogically sound.

The role of the Global Scale of English (GSE)

Smart Lesson Generator is aligned to the Global Scale of English (GSE). This powerful scale, ranging from 10 to 90, is aligned with the Common European Framework of Reference (CEFR) and provides detailed learning objectives for each proficiency level. ÌýThe GSE ensures that the content generated by the Smart Lesson Generator is appropriately levelled.

Think of the GSE as a precise filter. It meticulously checks every piece of content to ensure it meets high standards. This means that the activities created are challenging yet achievable for students. With the GSE powering the Smart Lesson Generator, teachers can confidently deliver lessons that match their students' skill levels and help them progress.

Supporting English language teachers into the future with AI

The Smart Lesson Generator helps teachers create high-quality activities quickly, which allows them to spend more time focusing on their students. The tool also helps teachers develop personalized learning paths that enhance student progress and engagement, and is continually updated with input from ÃÛÌÒapp's experts and teachers worldwide. All this means that you can confidently plan lessons, knowing that the Smart Lesson Generator is your reliable partner in your quest to nurture the minds of tomorrow.

    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 ÃÛÌÒapp. 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.
