THECREATORPBL-TDLE Framework
Problem-Based Learning (PBL) through Teaching by Demonstrations and Learning by Experiments (TDLE).
PBL-TDLE is an original teaching–learning framework conceived, engineered and proven by THECREATOR Education — moving classrooms from content delivery to genuine problem solving.
From content delivery to problem solving.
The future belongs to nations that can solve problems — every product, medicine, technology and patent begins with a problem that was solved. So our classrooms make problem-solving the central daily activity, not an add-on after teaching.
Also, every leading national and international university admissions test is built entirely around problem-solving in the STEM subjects — Physics, Chemistry, Biology and Mathematics. Their goal is to measure a student's ability to solve problems, not to reproduce facts.
The world's top universities also give strong preference to students who qualify high-level academic examinations — IPhO, IChO, IBO, IMO, AP, AMC, BPhO and similar. Even NEET and JEE are, at their core, completely problem-based exams.
A student who wants to compete for these opportunities must therefore be trained in problem solving — and that is exactly what PBL-TDLE is designed to build.
A real problem is a novel situation whose solution path isn't obvious. Students must:
- Understand the situation
- Identify given information & required outcome
- Select and connect relevant concepts
- Apply them systematically
- Evaluate and justify the solution
Students develop problem-solving skills in STEM using problems — unfamiliar situations in Physics, Chemistry, Biology and Mathematics.
To solve a problem — an unfamiliar situation — a student must analyse it, understand it and then apply the right concepts (ideas, principles and laws) to arrive at a solution.
An unfamiliar STEM situation.
Break it down. Understand what is given, what is asked.
Bring in the ideas, principles and laws that fit.
Reach a verifiable, reasoned solution.
Concepts are developed — not just explained.
In TDLE, students investigate and verify each concept by performing experiments designed with scientific apparatus. This is the only way a concept truly develops so that it can later be applied to solve problems.
Concepts must be developed so that they can be applied.
The central learning sequence of PBL-TDLE.
Every PBL-TDLE lesson follows the same eight-step sequence — from a diagnostic that maps the class's concepts, to a solution that each student verifies for themselves. Problem-solving stops being a mystery and becomes a repeatable, evidence-based process.
AI Diagnostic Test
An AI-based diagnostic test maps the target concepts against the cohort — pinpointing exactly what needs to be developed for this class.
CoPE-App Generates a Tailor-Made Lesson Plan
The cloud-based CoPE-App produces a digital, tailor-made lesson plan — a curated list of concepts, problems, experiments and apparatus for the day.
Teacher Displays the Problem
The lesson opens with an unfamiliar situation — a real problem on the topic to be taught, displayed to the whole class.
Students Analyse the Problem
Students break it down themselves — identifying the inputs, the outputs, and the concepts they don't yet know.
Teacher Demonstrates Every Concept Live
Using the CoPE-App concept list and the students' own analysis, the teacher demonstrates each concept with the designed experiments and apparatus — making measurements, graphing, doing data analysis and verifying every concept in front of the class.
Students Investigate & Verify Independently
Each student then repeats the investigation — verifying every concept for themselves with the apparatus, while the teacher moves through the lab guiding, watching and confirming that every learner has actually verified every concept.
Students Apply Concepts to the Problem
With every concept now genuinely developed, students return to the original problem and apply their developed concepts to solve it.
Solution Displayed · Students Self-Correct
The teacher displays the solution. Every student cross-checks their own work against it, identifies gaps, and corrects them on the spot.
The teacher first demonstrates each concept with real apparatus. Students then investigate and verify every concept themselves. Once developed, they apply the concept to the curriculum-based, advanced, real-life and open-ended problems that appear on their screens.
Problem-solving becomes the application of developed concepts — not the mechanical use of memorised formulas.
A single, coherent architecture for problem-based learning.
Concept Labs supply the apparatus and experiments. The CoPE-App orchestrates the daily academic plan. IDEA pedagogy keeps learning continuously assessed and corrected — together forming one integrated engine.
From classroom to Concept Lab — where students investigate, understand, apply and solve.
One of the fundamental innovations of PBL-TDLE is the transformation of conventional classrooms into Concept Labs — where learning shifts from passive listening to active investigation and problem solving.
Concept Labs are equipped with several hundred global-standard scientific apparatus and several thousand carefully designed experiments spanning from Upper Kindergarten (UKG) to Grade 12. Students investigate, observe, measure, analyse, interpret and verify scientific and mathematical concepts through direct experience.
For the secondary section, dedicated Concept Labs are available separately for Physics, Chemistry, Biology and Mathematics. In the primary section, every classroom itself functions as a Concept Lab — a fully equipped space where students continuously learn through demonstrations, experiments, observations, measurements and problem solving.
Hundreds of apparatus. Thousands of experiments. Every concept. Every student.
An AI-powered academic engine — one CoPE-App per unit, per subject, per class.
The CoPE-App is our proprietary cloud lesson-plan engine. For every unit in Physics, Chemistry, Biology and Mathematics — and for every class from Grade 0 (Upper KG) to Grade 12 — the platform generates a purpose-built CoPE-App that bundles the four things a teacher actually needs to run a Concept Lab.
The CoPE-App is already live for partner schools at tce-pbl.uk — with dedicated logins for teachers, students and school leaders.
Concepts are developed by apparatus & experiments — and applied on problems for their solution.
1,500+ global-standard instruments make every concept measurable.
Thousands of designed experiments to investigate & verify each concept.
The idea, law or principle — developed through experience, not memorised from a textbook.

Concepts
Build strong conceptual foundations
Concepts are the ideas, laws and principles of science and mathematics. They must be developed — not merely known — because they must be applied in problem solving. For every topic, unit and chapter, the required concepts are identified from the curriculum prescribed by the board and included in the CoPE-App.
See the concept in action
Explore it through experiments
Observe, measure and confirm
Link concepts to real life
Real-life, open-ended problems
Develop analytical thinking & problem solving
Problem solving is the process of applying concepts to find solutions to new and unfamiliar situations. The CoPE-App's problem bank of 10,000+ newly created, real-life, open-ended problems trains students to apply concepts. Each problem is engineered around the concepts to be developed and applied in that specific topic.

The AI that reads, analyzes and maps the cohort — before the teacher begins the lesson.
Sitting behind the CoPE-App is an AI-based diagnostic system that maps every student's understanding of every concept — surfacing strengths, gaps and misconceptions across the whole cohort before teaching even begins. The next lesson is then written to fix precisely what the data says.
Concept-level diagnostics
The AI engine maps every student's understanding of every concept before teaching begins — surfacing strengths, gaps and misconceptions at the cohort level.
Real-time formative assessment
Every problem, every experiment and every response is logged. Mastery of each subtopic is scored continuously — not left to end-of-term exams.
Personalised lesson planning
The next lesson is generated per cohort — reinforcing weak concepts, escalating strong ones — so the teacher walks in with a plan the AI has already tailored.
Transparent dashboards
School leaders, teachers, parents and students all see the same signal: which concepts are mastered, which are not, and what will be worked on next.
Teacher-independent, system-driven learning. The CoPE-App creates a fully integrated ecosystem — connecting teachers, students, parents and school leaders on a single platform — ensuring complete transparency, continuous formative assessment, concept mastery and problem-solving excellence for every student.
Three tiers of problem solving — Foundation, Analytical, Olympiad-grade.
Foundation & Curriculum
Curriculum-level problems that build conceptual understanding and first application.
Advanced & Analytical
Higher-order problems requiring the integration of multiple concepts.
Olympiad & Research
International Olympiad, advanced-entrance and real-world innovation-level challenges.
Identify the Problem
Learning begins with a real-life, open-ended problem displayed by the teacher. Students analyse it and scientifically identify three things.
The information, values, conditions and data already provided.
The result, target or solution the problem is asking for.
The principles, formulas and scientific ideas required to solve it.
Assessment as an integral part of learning — not an exam after it.
In the PBL-TDLE Framework, assessment is not treated as a separate examination conducted after teaching has been completed. It is integrated into the learning process through Formative Continuous Assessment (FCA) during every stage of IDEA pedagogy. At every stage, the teacher observes and evaluates each student's work, assigns marks immediately and provides feedback on the spot — rewarding participation, effort, independent attempts and self-correction.
The purpose of FCA is not merely to record marks. Its primary purpose is to identify learning gaps, encourage every student to attempt the work, correct misconceptions and help learners progress towards concept mastery and independent problem-solving.
FCA1 takes place every day during the actual classroom learning process — following the student through every stage of problem identification, demonstration, experimentation, execution and self-correction.
Identifying the Problem
Students first examine the situation presented. The teacher assesses whether they can:
- Understand the given situation
- Identify the central problem
- Recognise the information provided
- Determine what needs to be investigated
- Recall relevant prior knowledge
- Ask appropriate questions
Marks are awarded for participation and the ability to identify and understand the problem. Students who misunderstand are guided to reconsider and correct their interpretation before proceeding.
Developing the Concepts
Concepts are introduced through demonstrations, apparatus and guided discussion, then developed and verified by students performing experiments themselves. The teacher assesses:
- Participation in the demonstration and experiment
- Understanding of the concept being investigated
- Correct handling and use of apparatus
- Observation and measurement skills
- Accuracy of recorded information
- Analysis and interpretation of results
- Connecting experimental evidence with the concept
- Drawing appropriate conclusions
Students receive immediate feedback while the activity is still taking place — errors are reviewed, identified and corrected under the teacher's guidance, with marks awarded at every stage.
Executing the Problem
Students independently attempt the solution to the given problem. They are expected to:
- Select the concepts they believe are relevant
- Decide how those concepts should be applied
- Develop their own method or strategy
- Organise the solution into logical steps
- Perform the required calculations
- Record their reasoning and final answer
- Complete the solution independently
The teacher rewards a genuine attempt with marks even if the final solution is incorrect — encouraging independent thinking without fear of losing marks. Students must construct their own solution before seeing the standard one.
Assessing the Learning
The teacher displays and explains the standard solution. Students compare their own work step by step, examining:
- Whether they selected the correct concepts
- Whether each concept was applied appropriately
- Whether the method was logically organised
- Whether any important step was missing
- Whether calculations were accurate
- Where their reasoning differed — and why
- How their solution could be improved
Students correct their own work wherever they find an error. The teacher checks the corrected solution and awards additional marks for successful self-assessment and self-correction — making assessment an active learning process.
During execution, students receive marks for attempting the problem independently — recognising effort, reasoning, concept selection and the willingness to solve, even when the final solution is incorrect.
During assessment, students receive further marks for comparing their work with the standard solution, identifying errors and correcting themselves — mistakes become part of learning, not failure.
FCA1 marks are entered into the Learner App in real time, continuously updating every student's academic performance throughout the school day — capturing participation, independent attempts, experimental work, concept application and self-correction.
Leaders and academic coordinators see participation, mastery, difficult problems, students needing support and progress after correction — across classes and periods. Intervention happens while the unit is still being learned, not after a later examination.
Parents view their child's performance in real time — participation, experimental work, independent problem-solving attempts, concept application, self-correction and assessment outcomes — not just occasional report cards.
While FCA1 evaluates learning continuously, FCA2 assesses whether students can independently apply the concepts developed throughout the unit. Students solve carefully selected problems as a home assignment and present their solutions before their peers and teacher.
- Explain the problem clearly
- Identify the concepts required
- Describe why each concept is relevant
- Explain how each concept is applied
- Present every step of the solution
- Justify calculations and reasoning
- Interpret the final result
- Respond to questions from teacher and peers
- Defend or revise the solution when required
FCA2 does not assess the final answer alone — it evaluates the complete thinking process. Peer discussion lets other students examine different methods, raise questions and compare approaches, strengthening both presenter and audience.
Regular presentation prepares students to communicate their ideas confidently in examinations, competitions, interviews, research discussions and professional situations.
Through FCA, learning no longer remains assumed or invisible. Teachers can verify it, students can improve it, school leaders can analyse it and parents can follow it in real time. Formative Continuous Assessment makes learning visible, measurable, correctable, verifiable and accountable — while ensuring every student receives repeated opportunities to attempt, learn from mistakes, correct their understanding and achieve mastery in concept application and problem-solving.
“PBL-TDLE is based on the fundamental principle that every student who actively engages in learning can develop concepts and become a successful problem solver, irrespective of their inherent talent or starting ability.”
