Mathematics can be a demanding subject, particularly when pupils do not yet fully grasp a concept, cannot identify where they have gone wrong, or are unsure how best to begin a problem. At the same time, teachers are a vital source of guidance. Fortunately, Wellington College International Tianjin has a strong culture of mutual support, with many talented mathematicians who are both highly capable and generous in helping their peers. With clear structure, thoughtful timetabling, and teacher guidance, we have established a peer tutoring system to make support readily available to those who would benefit most.
This is the Peer-to-Peer Mathematics Mentorship, a framework developed by Senior School Mathematics Teacher and project initiator Mr Cowsill and driven forward by pupils themselves. It is a learning model centred on peer support, underpinned by data and feedback, to elevate pupils who would benefit from additional mathematical support.


Real Improvement: Leapfrog Progress in Recent Assessments

The project has chiefly focused on Year 12 (non-Further) Mathematics pupils for the CAIE 9709 AS Mathematics P1 and P5 courses, and on Year 11 IGCSE Additional Mathematics. Mr Cowsill recalls that although the approach was first trialled as early as November 2025, it truly assumed the shape of a full pilot following a series of January 2026 assessments. At that point, pupils’ areas for development became far more visible, enabling the tutoring to be targeted with much greater precision to individual needs.
Recent assessment data show substantial improvement, particularly among pupils involved in structured mentorship.

Mr Cowsill emphasises that these improvements have been shaped by a range of factors—independent work undertaken by pupils, support provided by teachers both in and beyond lessons, and the gradual deepening of understanding over time. “That said, the results are extremely encouraging, the timing is notable, and I could not be prouder of the dedication shown by our pupils, both mentors and mentees.”
Why "Pupils Teaching Pupils"? It Started with a Classroom Moment

Speaking about the project’s origins, Mr Cowsill recalled a striking success story from last year. One pupil was having difficulty with some concepts in P5 Mathematics. Over the following months, he worked through a large number of papers with sustained discipline. After each one, Mr Cowsill marked it, explained the errors in detail, and asked him to revisit the same problems later using written notes. His scores rose steadily over time, and in the final CAIE examination, he ultimately achieved 86% (A). This convinced Mr Cowsill that high-frequency, highly personalised error correction and explanation are instrumental in overcoming mathematical barriers.
Rather than viewing support solely through the lens of traditional classroom provision, the department began to explore how it might be further enhanced through pupil leadership and collaboration. A particularly revealing moment came in one mathematics lesson, when Mr Cowsill worked with one of his top pupils, Tony, to teach a class. Tony immediately rose to the occasion, delivering exceptionally clear and detailed explanations for each problem. He organised the class into groups, used separate whiteboards, and incorporated think-pair-share activities with remarkable confidence and fluency. As Mr Cowsill reflected, he was “essentially an 18-year-old master teacher, as though he had taught the lesson a hundred times before.”

From that insight, a clear model began to emerge: teachers would provide the structure, resources, and feedback, while capable pupils would take on more intensive one-to-one mentoring. At its busiest, the project facilitated between 15 and 20 one-to-one sessions each week, with pupils engaging in regular after-school study support.
Tony: From Co-Founder to Practitioner
As co-founder of the project and this year’s Oxford University offer-holder, Tony (a Year 13 graduate) initially worked with small groups, covering Pure Mathematics 1 for Year 12 pupils, and helped Year 13 Further Mathematics pupils consolidate topics that frequently generated high error rates in examinations. Later, after discussion with Mr Cowsill, the team concluded that one-to-one tutoring was more targeted and effective, and the programme gradually shifted towards individual support. These sessions often extended beyond the school day, sometimes well into the evening. In total, Tony personally contributed more than 18 hours of mentorship.。
He says the experience strengthened his abilities, “I feel very honoured to contribute to academic peer support through this programme, and I sincerely thank the school and all the teachers for their continuous encouragement.”

In his view, "teaching" is not simply giving answers, but pulling out the other person's thinking, breaking down mistakes, and rebuilding methods. This is precisely one of the core abilities needed for university and future research.
Among the mentor team, Jack is another highly active pupil mentor. Since last December, he has completed 13 hours of formal mentorship focused on IGCSE Additional Mathematics and A-Level Mathematics. In Jack’s view, some of the most valuable moments occur outside a scheduled session, whether in a brief exchange during a lesson or while working through a difficult problem in free time. He does not regard it simply as formal teaching, but rather as the sharing of different ways of thinking. Seeing a classmate move from uncertainty to a moment of real clarity, he says, brings a sense of reward that a test score alone cannot replicate.

One Mentee’s Journey: More Than Just a Grade Change
If the data demonstrates the project’s effectiveness, one mentee’s story illustrates its deeper significance.
Reflecting on his earlier experience, the mentee admits he often struggled to sustain momentum in lessons, which affected his academic performance. Yet Mr Cowsill remained steadfast in his encouragement. After class, he regularly took time to revisit the fundamentals with him and encouraged him to join the peer tutoring group. He describes that consistency of support as the factor that helped him keep moving forward.
With patient guidance from Tony and other classmates, the mentee gradually closed the gaps in his understanding. At the same time, he developed the discipline to review errors consistently and continue practising with purpose. The impact has become increasingly evident: he has recently earned an A on a practice paper.
What resonates with him most, however, is not simply the grade itself, but the realisation that when someone continues to believe in you, and you decide to take responsibility for your own progress, learning begins to feel far more possible. In his words, “As long as you are willing to work hard, it is never too late to improve.”
A Sustainable Mutual Support System
To keep the project sustainable, the maths department provided a clear system of support:
Teachers would first mark the mentees’ in-class work (often practice exam papers) and share it with both the mentor and mentee. Mentors would then help mentees work through the problems they got wrong: first asking them to reattempt the problems and talk through their reasoning as they go – Oxbridge interview style – before giving clear, detailed explanations where needed. Where appropriate, the mentor would also generate a set of similar practice questions using AI, allowing the mentee to tackle targeted problems that address specific weaknesses and consolidate key techniques.
Teachers coordinated the time and venue, matched mentors and mentees, and arranged fixed or flexible sessions. An incentive structure was introduced, awarding house points to both mentors and mentees per session. As pupils began to show improvement, the school would share their paper with both the mentor and the mentee, along with a congratulatory message, and award additional house points to recognise their achievement.
If mentors encountered difficulties, they were encouraged to seek support—either from another mentor or directly from Mr Cowsill (or another mathematics teacher).
The school also formally recognised pupil contributions. Mentors were acknowledged in the assembly, where they were invited on stage to receive certificates documenting their mentorship hours and mentorship pins to wear on their blazers. The certificates, signed by senior school leaders, provide pupils with a formal record of their work, which they can include in university and job applications.

Turning "Asking for Help" into a Habit and "Collaboration" into a Skill
Mr Cowsill believes that the most significant outcome of the mathematics mentorship project is not reflected solely in grades, but in the cultivation of a broader learning culture.
For mentees, the journey is one from “I can’t” to “I can improve through effort”, from avoidance to a growing willingness to ask questions and seek support. For mentors, teaching requires them to reorganise knowledge, sharpen their logic, and learn how to communicate effectively with peers at different levels—a valuable preparation for university seminars and collaborative work. For the year group as a whole, the message is equally important: pupils are not competing with one another; in external examinations, they are, in many respects, striving together against a much wider cohort.
Looking ahead, Mr Cowsill intends to further develop and extend the initiative in the next academic year. This will include broadening mathematics mentorship to a wider cohort of pupils, strengthening collaboration with colleagues, preparing structured resource materials such as topic-based question sets, and introducing mentor training sessions focused on effective pedagogical approaches, including the “I do, we do, you do” model. Following the examination period, the team will gather feedback, analyse examination outcome data, and consider additional forms of formal recognition.

Mathematics has never been a subject that relies solely on talent. It is more like a long run: some run fast, some start slowly. But as long as someone is willing to run alongside and pull you forward, and as long as you are willing to do one more problem and correct one more mistake, change will happen.
In this peer support movement sparked by pupils, what we see is the most precious foundation of a school: turning individual excellence into mutual achievement.
