What is COIL and How Does It Make a Project Truly Global

COIL in education connects your classroom with a real partner class in another country — so students don't just study global issues, they work on them together. Discover how Class2Class makes international collaboration accessible for any K-12 teacher, from the first project to the last.

Picture this: your students have spent three weeks studying the water crisis. They have read articles, watched videos, and written a report. They know the facts. But when you ask them what someone their age in Kenya or Peru thinks about this problem — someone who lives it every day — the room goes quiet.

That is the gap COIL in education fills. COIL, short for Collaborative Online International Learning, is the approach that connects your classroom with a partner class in another country, so students don’t just study global issues. They work on them with people who experience those issues from a completely different angle.

At Class2Class, COIL is not an optional feature or a one-off field trip. It is the axis around which every project turns. This article explains what COIL is, why it works, how it fits inside a Class2Class project, and how you can take your first step — even this week.

What Is COIL in Education?

COIL stands for Collaborative Online International Learning. At its core, COIL in education is a structured approach where two or more classes from different countries work together on shared tasks, using digital tools to bridge the distance.

This is not a pen pal program. In a traditional exchange, students write a letter and wait for a reply. In a COIL project, students investigate a shared question together. They compare what is happening in their own community, they share their findings with the partner class, and they co-create something — a presentation, a proposal, a shared piece of research — that reflects both perspectives.

The collaborative online international learning model was developed in higher education but has grown significantly in K-12 settings in recent years. Research confirms why. A 2022 study published in the International Journal of Educational Technology in Higher Education found that COIL virtual exchanges significantly improve intercultural competence compared to traditional classroom instruction. A 2023 follow-up study showed meaningful gains in intercultural skills for students who participated in a structured virtual exchange — gains that were not present in the control groups.

For a K-12 teacher, this evidence points to something practical: when students connect with a real partner class and work on something real together, they develop skills that no textbook can simulate. They learn to communicate across cultural difference. They learn to listen when the other person sees the world differently. They learn that a global challenge is not abstract — it has a face on the other side of the screen.

How COIL Works Inside a Class2Class Project

Class2Class builds COIL in education into every project from the beginning. The Class2Class educational framework describes COIL as the “transversal axis” of the platform — meaning it is not one methodology among many. It is what gives every project its international dimension and its collaborative meaning.

The platform offers three project approaches, and COIL is present in all of them:

  • Explore Cultures — students connect with a partner class to discover each other’s daily lives, traditions, languages, and schools. This is the easiest entry point for new teachers.
  • Explore Global Challenges — students investigate a shared real-world issue — climate change, food access, digital inclusion — and compare how it looks in their different communities.
  • Create Solutions — students go further: they co-design a proposal, a product, or an action plan that addresses a shared problem.

In each approach, what changes is the depth of the collaboration. What stays the same is the connection: real classrooms from different countries working on something meaningful together.

Class2Class handles the practical challenges that often stop teachers before they start. You do not need to find your own partner teacher. The platform’s matching system connects you with a teacher whose class, grade level, and project interests are compatible. The platform operates in 144+ countries, which means there is almost always a relevant partner available. Once matched, the platform gives both classes a shared project board where they exchange materials and track progress. Meetings happen through video call tools your school already uses — the platform provides the structure, not another tool to learn.

Project-Based Learning (PBL) provides the pedagogical design — students investigate, build, and share. COIL provides the international collaboration framework — the connection that makes the investigation genuinely global. These two methodologies work together inside every Class2Class project. They are not stacked on top of each other; they are integrated.

What Students Actually Do in a COIL Project

One of the first questions teachers ask is: “What exactly do my students do?” COIL in education is concrete, not abstract. Every Class2Class project is organized around four activity types that give the collaboration a clear rhythm.

Icebreaker — the first contact. Before students can collaborate, they need to meet. An icebreaker activity might be a short video about their school, a photo board of their neighborhood, or a live call where each class introduces itself. The goal is to build curiosity and connection.

Working in Class — the substantive work. Both classes investigate the shared question, compare their findings, and build something together. This is the heart of the COIL project. Students are not just exchanging information — they are co-creating.

Presentation — sharing the result. Students present what they built to the partner class. They explain their findings, answer questions, and hear the partner class’s perspective on the same work.

Reflection — looking back. Students reflect as a group: What surprised them? What did they learn about the partner community? What did they learn about their own? This structured reflection turns the experience into lasting learning.

A clear example is the My School, Your School project, a ready-to-use template in the Class2Class project library. Teachers from Argentina, India, and Ukraine used it to connect their classes through a structured exchange — you can read their full story here. Each class prepared a short presentation about their school — their classroom, their neighborhood, a typical school day. They met online, shared their presentations, and asked each other questions. What started as a simple icebreaker became a rich conversation about what school means in different parts of the world. The project took two sessions. The connection lasted much longer.

This is collaborative online international learning working as it should: a manageable starting point that opens a genuinely global conversation.

What Students Develop Through COIL

When students participate in a COIL international learning project, they build competencies that are visible, trackable, and meaningful.

The two competencies most directly connected to COIL in education are Intercultural Communication — the ability to interact respectfully with people from other cultures, to listen carefully, and to express ideas across language gaps — and Global Awareness — the ability to read a local situation through a global lens, and to understand how a challenge in one country connects to challenges elsewhere.

UNESCO’s Global Citizenship Education framework (2020) names intercultural understanding and global awareness as foundational competencies for students in an interconnected world. Class2Class evaluates both through group evidence that students produce during the project — with the teacher making the final call on what each group has demonstrated.

COIL also develops Digital Literacy, Collaboration & Teamwork, and Critical Thinking naturally, because the project requires students to work digitally, coordinate across time zones, and compare evidence from different cultural contexts. Project by project, these skills grow. Students who participate regularly in international collaboration leave school better prepared to work in diverse teams, navigate different perspectives, and engage meaningfully with global challenges — exactly the skills that matter most for active citizenship in today’s world.

How to Start Your First COIL Project This Week

You do not need to design a full semester program to try COIL in education for the first time. The best starting point is an Explore Cultures project — a short, structured experience of one to two hours that gives your class a real international connection without a long preparation process.

Here is how it works:

  1. Create a free account on Class2Class.
  2. Open the Project Definition Assistant — a step-by-step tool that helps you shape one idea into a clear project plan in about 15 minutes. You answer a few questions about your class’s age, your topic, and your goals. The assistant helps you structure the rest.
  3. The platform matches you with a compatible partner teacher. You review the match and confirm.
  4. Your class and the partner class complete the icebreaker activity — a short video introduction, a photo board, or a shared question.
  5. You schedule one online session — usually 30 to 60 minutes — for both classes to share and respond.

That is your first COIL project. From there, you can explore longer, more complex projects. But a 90-minute Explore Cultures session is enough to show your students what international collaboration really feels like — and to show you how manageable it is to run.

The platform is completely free for teachers. There are no subscriptions, no per-project fees, no hidden tiers.

Conclusión

COIL in education gives a project something no textbook, documentary, or simulation can provide: a real partner, in a real classroom, in a different part of the world. Your students stop studying global issues from the outside and start working on them with people who live those issues from a different perspective.

At Class2Class, COIL in education is not an add-on. It is the frame that makes every project genuinely international — not just in topic, but in practice. Start with one Explore Cultures project. See what happens when your classroom opens up to the world.
