Many parents share the same impression when they ask their children about their day at school: the day feels full – packed with information and a wide range of subjects—but there is rarely enough time to explore any one topic in real depth.
Lessons move quickly from one to the next, the school bell often interrupts just as discussions become engaging, and students switch rapidly from mathematics to literature, then biology and foreign languages, in a rhythm that leaves little room for reflection, questioning, or meaningful exploration.
In response to this reality, Avenor College will introduce 90-minute learning sessions for middle and high school students beginning in September 2026.
Why the Traditional 50-Minute Lesson Is Becoming Outdated
The change does not mean “more school” or simply extending traditional lessons. The thinking behind the new timetable is straightforward: students need time to develop deep understanding, ask meaningful questions, make connections, and apply what they learn.
“If we want students to develop critical thinking, analytical skills, and independence, we also need to provide the conditions that make this possible. Deep learning cannot happen in a rush,” explains Dana Papadima, Educational Director at Avenor College.
Longer learning blocks allow teachers to design experiences that more closely reflect how learning happens in real life. There is time for explanation, collaboration, debate, hands-on activities, experimentation, mistakes, and meaningful feedback.
“Sometimes the most valuable moments in a lesson happen only after students have had time to immerse themselves in the topic, formulate their own questions, and begin thinking more deeply,” says Dana Papadima.
This model has been widely adopted for many years in international schools, where longer learning sessions are common practice, particularly at middle and high school level.
Richard Thomason, Head of Secondary School at Avenor College, believes that the way learning time is organised has become an increasingly important topic in international education.
“Across many international education systems, learning blocks longer than 50 minutes are already standard practice. This is not an experimental trend but part of a long-standing discussion about how to organise time in ways that support deep learning rather than simply covering content as quickly as possible,” he explains.
He points to international research on school timetabling and its impact on learning, which suggests that well-designed extended learning sessions create stronger opportunities for inquiry-based learning, collaboration, problem-solving, and immediate feedback. A recent report published by Brown University distinguishes between the amount of time students spend at school and what the authors describe as active learning time – the time during which students are genuinely engaged in the learning process. Ultimately, this is the key question: not simply how long students spend in the classroom, but what kinds of learning experiences that time makes possible.
How Longer Lessons Support Critical Thinking and Deeper Learning

Richard Thomason emphasises that 90-minute sessions are not simply an extension of the traditional lecture-based lesson.
“No student can remain fully engaged for 90 minutes if a lesson consists solely of teacher-led instruction. These learning blocks are effective because they combine different rhythms and approaches: direct instruction, reflection, collaborative work, practical application, feedback, discussion, and independent learning. In reality, longer sessions give teachers greater pedagogical flexibility while giving students more space to think,” he says.
In other words, they reduce the feeling of constantly rushing through the curriculum. Students have more time to process new information, engage actively with ideas, and become participants in the learning process rather than simply receiving new content.
How Student Assessment Changes Within 90-Minute Learning Sessions
Mihaela Ancuța, Mathematics Teacher at Avenor College and BSO Inspector, explains that longer learning blocks also transform the way teachers can assess students’ progress.
“In a traditional 45 or 50-minute lesson, there is often not enough time to truly understand how a student thinks. Within a 90-minute session, however, teachers can observe how students analyse problems, explain their reasoning, collaborate with others, learn from mistakes, and gradually build understanding. At the same time, teachers can design opportunities for inquiry and discovery, creating different contexts in which students think deeply, ask questions, and develop solutions both independently and collaboratively.
For teachers, this is incredibly valuable. Mathematics is about far more than applying an algorithm quickly. It is about analysis, reasoning, exploration, and the ability to transfer concepts to new situations. All of this requires time,” she says.

At Avenor, we actively contribute to the conversation about education in Romania by promoting best practices and collaborating with respected editorial partners in the education sector. Our goal is to bring greater clarity and perspective to the dialogue between schools and families, supporting informed, thoughtful decisions about children’s educational journeys.


“There is a common assumption when people talk about international education: that, in order to succeed in a global world, children must gradually distance themselves from where they come from. We believe exactly the opposite. Children need roots just as much as they need wings. They need to understand the world, but they also need to understand who they are. That is why we have built an educational model that opens doors to international universities and opportunities while remaining firmly connected to the language, culture, and values that shape our students’ identities. Our goal is not to produce graduates who feel they must choose between Romania and the wider world, but young people who are confident enough to contribute meaningfully to both,”
“Preserving cultural identity cannot be achieved simply by adding a Romanian language class to an international timetable. It is built every day through what students study, the questions we ask them, and the connections we encourage them to make. At Avenor, we want our students to understand both the great universal ideas and values and the culture they come from. We study Romanian literature alongside world literature, explore questions of identity, history, and society, and develop students’ writing, reasoning, and communication skills in Romanian to the highest standards. We believe that a young person who is prepared for the future should be able to think critically and communicate with equal confidence in both the language of the world and the language that defines them,”
“In the British Early Years system, learning is not artificially separated from play, exploration, or movement. It is built around the core principles of the British curriculum, which place each child’s individuality, positive relationships, and a stimulating learning environment at the heart of education. Young children learn through direct experiences, through their interaction with the world around them, and through the freedom to discover independently. That is why outdoor learning and autonomy are essential during the early years at Avenor College. When children are given the space to explore, make age-appropriate decisions, take on meaningful responsibilities, and learn through their interaction with nature, we are building far more than academic knowledge – we are fostering confidence, independence, and a lifelong positive relationship with learning,”
“In the early years of school, children need an environment where they feel safe, seen, and encouraged, while also benefiting from clear boundaries and consistent expectations. We believe that learning thrives when there is a balance between warm, supportive relationships and high standards. Our role is to create a framework in which children develop strong academic foundations through rigorous study while also nurturing their curiosity, collaboration, and creativity through play, transdisciplinary projects, and meaningful learning experiences,”


The paradox is that some of the most valuable things children learn have little to do with school subjects. They are not about letters, mathematics, or acquiring new information. They are about learning how to cope when things don’t go according to plan.

Nature: A Remarkable Teacher
Looking back on the past few years and on his experience at one of the world’s most prestigious universities, Andrei offers a mature perspective on what success truly means. He speaks about curiosity, discipline, balance, and the importance of never allowing a label to define who you are.
Curiosity and discipline: the combination that makes the difference


The second pillar is emotional safety. Here, educators and counselors serve as a secure anchor. Through authentic connection, active listening, and consistent support, they create the atmosphere of trust that allows children to move from “survival mode” into “learning
mode.”
In recent years, we have also noticed an important shift in parents’ perspectives. More and more families understand that nursery is not simply a place where children are supervised, nor just a stage before “real school” begins. It is an environment that has a profound impact on how children will approach learning later in life.
As a primary school teacher, one of the questions I hear most often in class, during maths lessons, is simple, but very profound: “


“During recruitment, beyond the rigorous assessment of professional competencies, we are also concerned with the deeper dimension of compatibility with Avenor College. We tell candidates the Avenor story and seek to understand whether we share the same vision of education and the same professional standards. For us, excellence in teaching goes hand in hand with responsibility, including a strong commitment to safeguarding principles and the ability to create a safe environment in which every child is protected, respected, and supported in reaching their full potential. Professionalization begins with competence, but it is strengthened through values and through the responsibility we assume for the impact we have on every student, every day,”
“Being in my first year at Avenor College, I discovered that professional development is not merely a theoretical concept but a genuine driver of everyday activity. The Performance Management process and the establishment of Professional Learning and Development (PLD) goals helped me define a clear direction from the very beginning. I feel that this system provides concrete support during the lessons I observe. I have learned tremendously by monitoring my progress and adapting my teaching methods. The impact is visible directly in the classroom, in my interactions with students from preparatory grade through fourth grade, where I can apply new techniques that keep them engaged, active, and curious. It is a continuous learning process that gives me confidence that I can make an authentic contribution to every child’s development.” –
“For me, professional development is a deliberate process that helps me maintain high standards in my day-to-day work. In a school that places such a strong emphasis on holistic development and the wellbeing of the entire community, I continually seek opportunities to refine my skills through professional learning. This has allowed me to participate in programs from the school’s professional development portfolio, such as Teaching with Love and Logic and From Values to Action: Making SMSC Visible in Secondary. This year, I also chose the AI Unplugged: Teaching Smarter, Not Harder course offered by Avenor, which is already helping me reduce part of my administrative workload and giving me more time to focus on the other important aspects of my role as a teacher and school counselor.” –
Authentic professional development requires dialogue and collective reflection, explain Avenor representatives.

Last but not least, the forest is where we teach their first lessons in civic responsibility. By learning how to keep the forest clean, children begin the transition toward critical and creative thinking, understanding that their actions have a direct impact on the environment.
Starting nursery is both an important beginning and a significant ending. It marks the start of a child’s experience within a wider community and a period of active exploration of the world around them. At the same time, it signals the end of a stage in which the child has been primarily exposed to the family environment.
