During the week beginning 27 July 2026, Understanding Academy welcomed a group of highly motivated teachers to Amsterdam for The 4Cs: Critical Thinking, Creativity, Communication and Collaboration in the Modern Classroom. Participants came from different professional backgrounds, educational settings and European countries, bringing a rich variety of experiences, questions and perspectives to the course.
The programme was not designed to explore the four skills as separate topics. Instead, its central purpose was to understand how critical thinking, creativity, communication and collaboration interact in meaningful learning.
It is easy to treat the 4Cs as four boxes to include in a lesson plan. An activity may be described as creative because students produce something, collaborative because they work in groups, or communicative because they present their results. In practice, however, learning is rarely so divided. Learners often need to examine information, develop ideas, explain their reasoning, listen to others and make decisions together.
Throughout the week, we therefore focused on integrating the four skills and reflecting on how they could support one another in different subjects, age groups and educational contexts.
Learning from Different European Perspectives
The international composition of the group was one of the course’s greatest resources. From the first day, participants shared information about their schools, learners, professional responsibilities and local challenges.
The school presentations went beyond introducing an institution. Teachers considered how their schools might collaborate, what benefits a partnership could bring, which digital tools would be needed and how cultural differences might influence the process.
These conversations demonstrated the 4Cs in action. Participants communicated their own realities, listened critically to different perspectives, recognised opportunities for collaboration and began generating new ideas together.
A familiar classroom practice in one country could be surprising to a teacher from another. A challenge experienced by one participant might already have been approached differently in another educational system. These differences did not create barriers. They became material for learning.
The teachers’ motivation shaped the entire week. They were willing to participate, experiment, question ideas and share their experiences openly. They did not simply ask whether an activity was entertaining. They considered why it worked, who might benefit from it, what difficulties could arise and how it could be adapted for their own learners.
Communication as the Basis of Participation
Communication was explored as much more than speaking clearly or delivering a successful presentation. Participants reflected on how everyday communication influences dignity, participation, relationships and the emotional climate of a classroom.
The group compared passive, aggressive and assertive responses to realistic situations involving students, colleagues, parents, meetings and group work. Passive communication may hide a person’s needs, while aggressive communication can damage relationships and make others feel unsafe. Assertive communication offers another possibility: expressing a need clearly and respectfully while remaining open to finding a solution.
Through practical scenarios, participants developed passive, aggressive and assertive answers before comparing which response best protected learning, dignity and clarity.
The activity Draw What I Say made the importance of clarification immediately visible. One teacher described an image while a partner attempted to draw it. During the first round, questions were not permitted. In the second, the listener could ask, check and clarify. Comparing the results showed that communication is not simply about transmitting instructions. It is a shared process in which both people contribute to creating meaning.
Participants also explored the “communication iceberg”. Above the water were words, gestures, tone and facial expressions. Below it were emotions, values, assumptions, cultural expectations and previous experiences. This was especially relevant within an international group, where the same behaviour may be understood differently depending on a person’s background.
Creativity Beyond Artistic Expression
Another important goal was to expand the meaning of creativity. Creativity was not presented as a special talent belonging only to artistic learners or teachers. It was understood as purposeful idea generation, evaluation and improvement.
Creativity can appear when learners ask questions, develop original explanations, select a different strategy, design a product or find a constructive way to respond to another person. It therefore belongs in every subject, not only in art, music or drama.
Participants experimented with several brainstorming approaches, including mind mapping, brainwriting, figure storming and changing the scenery.
Brainwriting gave everyone quiet time to develop ideas before an open discussion. This helped prevent the fastest or loudest voice from dominating the group. Figure storming asked participants to consider how a learner, parent, artist, scientist or school leader might approach a problem, helping them escape habitual thinking and examine an issue from another perspective.
The emphasis was not simply on producing as many unusual ideas as possible. New ideas also needed to be relevant, useful and connected to a genuine educational purpose.
Critical Thinking Before and After Creativity
Creativity opened possibilities, but critical thinking helped participants decide what to do with them.
Before looking for solutions, the group examined how to define a problem clearly. A meaningful problem statement needed to move beyond general complaints about time or money, explain why the situation genuinely mattered, identify who experienced it and focus on something that could realistically be influenced.
This demonstrated that critical and creative thinking are not opposites. Critical thinking should not be used only to reject ideas. It can help learners examine assumptions, understand a situation, establish criteria and improve an initial proposal.
The learning-design process followed a cycle of planning, trying, observing, gathering feedback, revising and trying again. Participants discussed why failure and revision are natural parts of learning. A prototype, presentation or lesson plan does not need to be perfect. It needs to make thinking visible so that it can be discussed and improved.
Collaboration with a Real Purpose
Collaboration was present throughout the course, but participants also questioned the assumption that placing learners in groups automatically creates collaborative learning.
Meaningful collaboration requires a shared purpose, opportunities for individual thought, clear communication and structures that allow different people to contribute. Brainwriting, group planning and decision-making tasks illustrated how collaboration can be organised so that participation is not limited to the most confident members.
In one activity, participants had to decide how to spend a limited school budget. They first formed their own opinions and then negotiated a group decision. They needed to analyse the options, defend their priorities, listen to alternative perspectives and reach an agreement.
The task integrated all four skills naturally. Critical thinking was needed to compare the options. Creativity helped the group explore different combinations. Communication allowed participants to explain their reasoning, while collaboration was required to produce a shared decision.
In another task, small groups created a checklist of actions teachers could take before, during and after a lesson. The international group brought different practices and assumptions to the conversation, allowing participants to create something richer than any individual contribution.
Reflection as the Thread Connecting the Four Skills
Reflection was not left until the final afternoon. It was present throughout the week.
Participants regularly considered what they had learned, why it mattered, what questions remained and how an activity could be transferred into their own teaching. They experienced each task as learners and then stepped back to analyse it as educators.
Who had space to contribute? What instructions supported collaboration? When did communication become difficult? Did the creative element still serve a clear learning purpose? What evidence of critical thinking could a teacher observe?
At the end of the course, participants began preparing lesson-planning checklists and dissemination materials to share with their colleagues. They also considered what changes they would make after returning home.
The goal was not to leave Amsterdam with a collection of disconnected games. It was to return home with a clearer approach to designing learning in which the four skills reinforce one another.
Critical thinking gives ideas direction. Creativity opens new possibilities. Communication makes thinking visible. Collaboration enables people to build something together.
With a highly motivated international group willing to question, listen, experiment and share, the 4Cs became more than the subject of the course. They became the way the course itself was experienced.
