Transform Your Teaching with TRIZ Principle 36: Phase Transition in the EFL Classroom

Hello, creative English language teachers! Are you on the hunt for unique ideas to enhance your lessons and inspire your students? Today, we’ll explore how to apply TRIZ Principle 36, “Phase Transition,” in the English as a Foreign Language (EFL) classroom. With three practical examples, you’ll be eager to incorporate this transformative approach into your next lesson. Let’s dive in!

What is TRIZ Principle 36: Phase Transition?

In the context of TRIZ, “Phase Transition” refers to the idea of using phase changes or transitions (e.g., solid to liquid, liquid to gas) to solve problems or improve a system. When applied to language teaching, this principle encourages educators to create transformative learning experiences by shifting the focus, format, or intensity of their lessons.

Practical Example 1: Activity Transformation

Design an activity that transitions between different language skills or formats. For example, start with a listening exercise where students listen to a dialogue or story. Next, transition to a speaking task by having students discuss the content or retell the story. Finally, shift to a writing activity where students compose a summary or continuation of the story. This seamless transition between skills can create a dynamic and engaging learning experience.

Practical Example 2: Changing the Focus

Introduce a “phase transition” in the focus of your lesson by beginning with a broad topic and gradually narrowing it down. For instance, start by discussing global environmental issues, then zoom in on specific environmental problems in the students’ home country, and finally, have students brainstorm ways they can contribute to solving these problems locally. This approach allows students to connect broader issues to their personal experiences and encourages critical thinking.

Practical Example 3: Intensity Shift

Incorporate an intensity shift into your lesson to keep students engaged and energized. Start with a low-intensity activity, such as a quiet reading or writing task. Then, transition to a more dynamic, high-intensity activity, like a debate or role-play. Finally, wind down with a low-intensity reflection or discussion. This variation in intensity can help maintain student interest and provide a well-rounded learning experience.


Applying TRIZ Principle 36, “Phase Transition,” to your EFL lessons can create transformative and engaging learning experiences for your students. By incorporating activity transformations, changing the focus, and shifting the intensity of your lessons, you can foster a dynamic and stimulating learning environment. Give “Phase Transition” a try in your next lesson and watch your students’ enthusiasm and understanding reach new heights!
