21C POCKET ADAPTIVE STEM LEARNING

When a pupil gets stuck, the teaching should change.

Not another set of questions. A more responsive way to understand Mathematics and Science, designed especially for pupils who need a different explanation.

21C Pocket brings curriculum knowledge, diagnostic assessment and accessible teaching together, so the next step responds to what a learner actually needs.

For schools, academy trusts, educators and education partners.

THE QUESTION WE STARTED WITH

A wrong answer tells you something. But not necessarily what.

Did a pupil misunderstand the Science? Forget a mathematical step? Misread the question? Or make a one-off slip?

Those difficulties deserve different responses. Repeating the same exercise may never address the real obstacle.

21C Pocket is designed to move beyond right or wrong, towards understanding what should happen next.

QUESTION-FIRST

Incorrect.Show the answer. Try another question.

TEACHING-FIRST

Why was it difficult?Check the underlying skill. Explain differently. Try again independently.

WHAT ADAPTIVE MEANS HERE

Not just a different difficulty. A different teaching response.

At the centre is a curriculum-led learning engine. It selects relevant teaching and questions from structured content, adjusting challenge and support to the evidence a pupil provides.

  1. 01

    Find the obstacle

    Starting checks and targeted questions help distinguish a misconception, a prerequisite gap and an isolated mistake.

  2. 02

    Explain in a way that helps

    Clear teaching, carefully worked examples and alternative representations address the difficulty, not just the symptom.

  3. 03

    Build independence

    Guidance gradually falls away. Fresh, unaided questions test whether the pupil can now apply the idea.

  4. 04

    Return and retain

    Later checks revisit important knowledge. Supported success and independent performance remain distinct.

Five adaptive teaching stages: identify a difficulty, explain, guide, practise independently and revisit later
Research-informed teaching sequence. Supported work and independent evidence remain separate.

The approach is informed by explicit instruction, formative assessment, worked examples, reasoning and retrieval practice. Completing questions alone is not treated as proof of mastery.

CONNECTED STEM, NOT ISOLATED SUBJECTS

What if the Physics problem is actually Maths?

Sometimes the scientific idea is understood, but a pupil cannot rearrange the equation. Our connected-subject design is intended to identify the missing prerequisite, teach it appropriately and return the learner to Physics.

One connected learning experience, with the right support at the right moment.

A COMPLETE STEM AMBITION

Four core subjects. One approach to learning.

We are building towards a connected GCSE and International GCSE learning environment for Mathematics and the sciences, designed to extend into further qualifications and STEM pathways.

Maths

Number, Algebra, Geometry, Statistics and more, with typed mathematical answers where appropriate.

Early access

Physics

Foundational concepts, calculations, graphs, adaptive explanations and carefully differentiated checks.

Early access

Biology

From cells and systems to the wider living world, with accessible scientific diagrams and targeted practice.

Expanding

Chemistry

Particles, reactions and quantitative reasoning, with connections to the mathematics behind the science.

Expanding
Maths, Physics, Chemistry and Biology subject cards, with connected knowledge and separate learning records

Coverage is being expanded and reviewed subject by subject. Availability differs by module, awarding body and qualification route. Future pathways include Functional Skills Mathematics and selected international curricula.

ACCESSIBILITY IS PART OF THE TEACHING

Not just access to a lesson. A better opportunity to understand it.

A pupil’s difficulty may begin with dense wording, a complicated diagram or a presentation that does not suit their needs. We want the experience to reduce those barriers, particularly for pupils with SEND and those who have struggled with conventional approaches.

  • Read aloud for page content and questions, with descriptions for graphs and diagrams.
  • Adjustable text sizes, high-contrast options and clearer display preferences.
  • Keyboard-accessible interactions and screen-reader-conscious presentation.
  • Plain-language explanations, worked steps and more than one way to represent difficult ideas.
  • Support that can be revisited without rushing a pupil on.

WCAG 2.2 Level AA informs the design and testing standard. This is a target, not a claim of independently certified compliance.

DESIGNED FOR REAL SCHOOL LIFE

One learning journey. Every perspective that matters.

21C Pocket is more than a pupil-facing app. Role-specific workspaces connect learning, support, administration and appropriate family oversight.

01 / LEARNING

Pupils

Lessons, adaptive practice, targeted help, accessible controls and honest progress.

02 / TEACHING

Teachers

Class progress, learning evidence, misconceptions and support requests.

03 / LEADERSHIP

School leaders

School and department insights to inform intervention and teaching priorities.

04 / OPERATIONS

School administrators

Classes, users, roles, roster imports and school-managed account settings.

05 / HOME

Parents and carers

Appropriate progress views and parent-led accounts for private home learners.

06 / ADDITIONAL SUPPORT

Tutors

Authorised access to relevant pupil progress, within defined permissions.

07 / PLATFORM

Platform administrators

School onboarding, operational oversight and permission-controlled, audited support.

Seven platform perspectives: pupil, teacher, school leader, school administrator, parent or carer, tutor and platform administrator
Who uses 21C Pocket.

SCHOOL-READY INFRASTRUCTURE

Useful to educators. Practical to administer.

  • School-controlled Microsoft and Google sign-in pathways, where configured and authorised.
  • Roster import, stable learner identities and scoped permissions.
  • School separation, controlled sharing and logged support access.
  • Personal learning evidence kept distinct by subject.

RESEARCH-INFORMED, NOT RESEARCH-WASHED

Serious about the science of teaching.

Ofsted has documented the consequences of moving pupils forward without secure prerequisite knowledge. Evidence-informed guidance also emphasises explicit instruction, scaffolding and self-regulated learning.

Our aim is to translate these principles into a practical, adaptive experience, then test what actually improves fresh unaided performance and later retention. We do not claim outcomes that have yet to be independently demonstrated.

GOOD QUESTIONS

A few things you may want to know.

Is 21C Pocket another AI chatbot or revision question bank?

No. It is a structured learning experience designed around curriculum skills, diagnostic questions, targeted teaching and independent evidence of learning. AI can support the wider content-development process, but a chatbot response is not our assessment method.

Does it cover the full GCSE and IGCSE curriculum today?

Not yet. The platform has early-access Maths and Physics pathways, with Biology and Chemistry in development. Available content and qualifications are identified as coverage is expanded and reviewed.

Can pupils learn at home without a school?

Yes, the platform includes a family-managed route for private learners. Access and onboarding arrangements depend on the stage of the early-access programme and relevant safeguards.

Can schools request a walkthrough or discuss a pilot?

Yes. We welcome conversations with schools, academy trusts, teachers, SEND specialists and education partners. Use the contact link below and mention 21C Pocket.

LET’S TALK ABOUT BETTER LEARNING

What could responsive teaching change for your pupils?

If you lead a school, support pupils with additional needs or are exploring an education partnership, we’d welcome the opportunity to show you the experience and hear what your learners need.
