An active-learning model that helps teenagers grow as professionals and as people, through real challenges, teamwork, responsibility and a second chance.
“Every young person can become a good professional and a good person if we give them real responsibility and a second chance.”
After graduating from university in 1992, I worked in industry while also delivering corporate training on professional programmes such as Cisco, Adobe and Microsoft. In 2017 I started teaching full time on the intermediate IT programme at Centro San Valero, with teenagers aged 16 to 18.
I soon saw that many of them left school with knowledge, but without what companies, and life, ask of them: listening, working in a team, meeting deadlines and taking responsibility for their mistakes. Closing that gap became my reason for being a teacher.
I bring my professional experience into vocational training to connect students with the world they will face when they leave school. My classes mirror that world as closely as possible: the tools companies use, challenges with deadlines and deliverables, industry-recognised certifications and teamwork. The 4D Methodology gives that way of working its structure.
I treat my students as the professionals they are going to be, but I also defend their right to make mistakes. My goal is not just for them to pass, but for them to leave school with confidence, a real professional profile and a place in society, and to understand that finishing school is the start of lifelong learning: reading, trying, making mistakes and trying again.
The 4D Methodology is an active-learning model we apply at Centro San Valero to bring vocational training closer to the way people work in real professional settings.
4D was born at Centro San Valero, which already worked with project- and challenge-based learning. I brought in the missing professional dimension and created a framework for the final project of the second year.
Students stop being mere recipients of content and become the protagonists of their own learning. Starting from challenges and projects, they work in teams, make decisions, solve problems, use professional technologies and tools and, finally, demonstrate what they have been able to build.
The methodology structures learning in four phases: Discover, Design, Deploy and Demonstrate.
It is a method for every student: its phased structure and teamwork support the inclusion of students with special educational needs.
Understand the client’s needs.
Everything starts with a challenge. Students must understand the problem, research, look for information, analyse alternatives and get to know the technologies and resources available to them.
This phase especially fosters curiosity, critical thinking, research and the ability to learn independently.
Soft skillsDecide on and plan the solution.
Once the challenge is understood, it is time to decide how to solve it. Teams propose their solution, share out responsibilities, choose technologies, design the architecture and plan the work.
There is not necessarily a single right answer. Students learn to make decisions, work as a team, argue for their choices and take on responsibility.
Soft skillsBuild and integrate it until it is up and running.
Ideas become a real solution. Students configure, develop, integrate, test and deploy what they have designed, using tools and technologies similar to those they will find in the professional world.
This is also when real problems appear: errors, changes, decisions that need revisiting or solutions that don’t work first time. Learning to solve them is part of the learning process itself.
Soft skillsTest it, explain it and provide evidence.
The project ends by showing and defending the work done. Teams present their solution, explain the decisions they made, justify the result and reflect on what they have learned.
In this way, we assess not only what they have done, but also how they did it, why they made certain decisions and what they are able to learn from the process.
Soft skillsThe 4D Methodology grew out of hands-on experience at Centro San Valero, but it is not tied to a particular subject, technology or school.
Its simple structure, Discover → Design → Deploy → Demonstrate, means it can be adapted to different vocational programmes, modules, educational levels and fields of knowledge.
Each school can apply it with its own resources, teachers, technologies and challenges.
The goal is to turn the classroom into a space where young people can face real problems, collaborate, make mistakes, take decisions, build solutions and demonstrate what they have learned.
It is not about reproducing a specific project, but about reproducing a way of learning.
4D is learning by doing, learning by deciding and learning by demonstrating.
Every second-year student in the Microcomputer Systems and Networks programme builds a simulated-company project following the 4D Methodology. The goal is to deliver a minimum viable product (MVP) good enough to hand over to a real company. The whole teaching team takes part, because this is not just a technical-skills project.
Centro San Valero is a state-funded private school in Aragón, Spain. Our students are teenagers aged 16 to 18 who arrive from lower secondary school or basic vocational training, still very dependent on the teacher. Alongside technical subjects, they need to start developing the soft skills they will need at work and in life. The classroom also includes students with special educational needs, who must be taken into account.
Students struggle to see isolated subjects as a whole. With 4D they do not complete separate exercises: they build one shared outcome, divide up the tasks, justify their decisions and work with every teacher to see the project through.
“The innovation is not using AWS or WordPress, which is already common in many schools, but how we connect every subject so that students build one shared outcome.”

After the first submission, every team receives improvement feedback to pass or to raise their grade.
None of this would be possible without my colleagues in the IT department and the leadership of Centro San Valero.
My students are teenagers. Alongside networks, systems and cloud, they are learning how to work with others, how to keep their word and how to recover from a mistake. The 4D project is designed so that these values are practised every day, not just talked about.
Each student owns tasks and deadlines within the team. When one of them falls behind, the whole team feels it; when they deliver, the team moves forward.
After the first submission, every team receives concrete feedback to improve. A second chance is not a gift: it is how people learn, at school and at work.
The IT equipment used at the AWS Tech Talent Arena is donated to NGOs afterwards, so what students learn with also serves the community.
Listening, respect and cooperation are part of learning. The simulated company and the final showcase at the AWS Tech Talent Arena provide the setting to practise them: I support teams through their disagreements so they listen to other views and reach agreements. Each company also builds its website in Spanish and English.
Success shows in the project and in how they work: they take part, respect differences and help a teammate when a task falls behind.
The 4D Methodology is for every student. Clearly defined phases and the way tasks are shared within each team allow students with special educational needs to take part in the project as full members and contribute from their own strengths.
Tutoring from the whole teaching team lets us adjust support for each student, and to prepare adaptations we also use a support app built with PartyRock, AWS’s generative-AI tool.
Data centres need a great deal of electricity and water. In the project, students study the sustainability of the architecture they deploy using AWS sustainability tools: they gather energy-use data, estimate the emissions impact, allocate it and publish the metrics.
They see that one architecture is not the same as another, and sustainability becomes part of their technical decisions as future IT professionals.
One student in my class knew more about AWS than anyone in the group. Technically he was the best, but he struggled with communication, teamwork, completing tasks and meeting deadlines. He preferred to work alone, and his team suffered for it.
Instead of rewarding only his technical level, I asked him to share what he knew: listen to his teammates, agree on decisions, take responsibility for his own tasks and present the product with his team. His group delivered a project far above the usual level.
What stayed with me is that talent without the ability to work with others is incomplete, and that sometimes the most gifted students need a teacher the most.
Each project is presented as Problem → Solution → Result.
The technology employers demand moves faster than the curriculum, and vocational students often finish without a credential that industry recognises.
I build the official education programmes of AWS Academy, Microsoft Azure, Google Cloud and Red Hat Academy, all of which I am an authorised educator for, into my modules. Students work in real cloud environments and prepare for industry certifications.
More than 8 years teaching AWS Academy to more than 400 students. Over the last 3 years, several students have earned AWS Cloud Practitioner and AZ-900 Azure Fundamentals certifications in the summer after finishing the programme, using discount codes provided by AWS and Microsoft.
Assembling a computer, configuring a network or deploying a cloud service is truly learned by doing it: against the clock, as a team and solving the unexpected, something an exam can hardly reproduce.
It is the final phase of the 4D Methodology: a competition between several schools, co-organised with Salesianos and Somorrostro, in which student teams take on hands-on challenges in computer assembly, networking and cloud, just as they would in a real job.
Students put what they learn in class to the test, measure themselves against students from other schools and gain confidence in their technical and teamwork skills. Afterwards, the IT equipment is donated to NGOs.

Ana, a higher-level vocational student, looked for work and found it at AWS data centres in Aragón. The 4D Methodology helped her pass all five interviews: she showed that what she learned in class was not just theory, and that she could put it into practice thanks to the Deploy and Demonstrate phases.
She continues studying with us online to complete her higher-level qualification.
I believe teaching grows richer when it is shared. That is why I spend part of my time training other teachers and opening up resources for anyone who needs them.
More than 5 years organising public-cloud courses for teachers across Spain. Next edition in January 2027: an introduction to cloud and how to adapt it to vocational, higher vocational and university courses.
As an AWS authorised trainer, I train teachers at every level and share the 4D Methodology with colleagues in schools across every region of Spain.

I am part of the AWS Community Builders programme, which keeps me close to new technologies I can bring into the classroom.
After they pass, I help students get cloud-certified, mainly in AWS and Azure, using discount codes both vendors provide.
We already share the 4D Methodology with Somorrostro (Bilbao), Salesianos and Montessori (Zaragoza), with a very good response. My goal is to take it to more teachers and schools, so that more young people can face real challenges, work as a team and discover what they are capable of.
An educational community that keeps sharing what it learns and gives more young people the chance to discover what they can do.
AWS, Microsoft, Google and Red Hat certify me as a trainer to deliver their official programmes, and I bring those programmes into my vocational classroom.
