Physics Misconception Diagnostics

The misconceptions your students carry are invisible — until they fail.

FundaFirst HS gives physics teachers the diagnostic tools to surface the exact misconceptions their students hold — in kinematics and Newton's laws — and a clear pathway to address them. Free classroom pilots with class-level heatmaps delivered within 48 hours of completion.

MISCONCEPTION SCANNER
KINEMATICS TRAP
"Drive A→B at 40 km/h, B→A at 60 km/h. Average speed?"
Most students say 50 km/h. The answer is 48 km/h — they use the arithmetic mean instead of total distance ÷ total time.
NEWTON'S LAWS TRAP
"You throw a ball upward. At the very top, what forces act on it?"
Most students add an upward "force of the throw" — a ghost force. Only gravity acts at the top.

The Problem

Students don't fail physics because it's hard

They fail because they carry misconceptions that textbooks never surface — and these persist through exams, university, and entire careers.
🎭

The Confidence Illusion

Students who score well on formula-based tests often perform worst on conceptual questions. They can calculate without understanding. They don't know what they don't know — and neither do their teachers, until exam results arrive.

🪤

Invisible Traps

Decades of physics education research document persistent misconceptions that survive conventional teaching. A student may solve F = ma problems yet believe a tossed ball carries an upward "force of the throw." The formula hides the failure.

🔍

No Diagnostic Layer

Most physics departments lack tools to systematically surface misconceptions before summative assessments. Teachers discover gaps too late — through exam results instead of targeted diagnostics.

Methodology

Trap-First Pedagogy

We don't start with the right answers. We start with the wrong ones — because that's where real learning begins. Our approach is grounded in standardised diagnostic instruments like the FCI and TUG-K, and three decades of published physics education research — not opinion.

Every diagnostic uses the same rigorous framework: surface the specific misconception, create cognitive conflict that destabilizes it, then provide structured guidance for rebuilding understanding from first principles. The traps we target are documented across multiple research traditions — from Trowbridge & McDermott's position-velocity confusion studies to Hestenes' Force Concept Inventory and beyond.

Diagnose

Carefully designed diagnostic assessments surface the specific misconceptions a student holds — not just whether they got the answer right, but which wrong mental model they're using. Students are mapped to misconception clusters with clear intervention pathways.

2

Confront

We present scenarios designed to make the misconception fail. When a student's wrong model produces an absurd prediction, the cognitive conflict creates genuine readiness for the correct concept. This is trap-first teaching — it works because it respects how minds actually change.

3

Reconstruct

Only after the old model is destabilized do we introduce operational definitions and correct frameworks. Students build understanding from first principles — not from memorized formulas, but from deeply held intuition about what concepts actually mean.

The Arc

A growing diagnostic arc across high school physics

FundaFirst HS isn't a single diagnostic. It's a structured sequence of misconception diagnostics covering IB, AP, A-Level, and GCSE Physics — each one surfacing and addressing the misconceptions specific to that topic, building on the last.

Every diagnostic follows the same research-backed framework: diagnose, confront, reconstruct. As the arc grows, teachers gain an interconnected toolkit for building real conceptual understanding — not a collection of disconnected test-prep drills, but a coherent diagnostic layer for the entire physics syllabus.

NOW AVAILABLE

Motion & Kinematics

Operational definitions, displacement, velocity, graph interpretation, and the traps that live in kinematics.

NOW AVAILABLE

Laws of Motion

Inertia, force-motion relationships, contact forces, free-body diagrams, friction, and Newton's third law — six focused modules.

About

Built on research, not guesswork

FundaFirst HS exists because of a simple observation: students don't fail physics because they're not smart enough. They fail because they carry invisible misconceptions that no one ever surfaces — and these misconceptions persist right through exams, university, and beyond.

We're a team with years of deep, research-backed experience in education — particularly in physics, where the gap between procedural competence and conceptual understanding is widest and most damaging.

Rather than creating another resource that repeats what textbooks already say, we went back to the published research. Our pedagogy draws on research instruments like the FCI and TUG-K, along with Arnold Arons' work on operational definitions, Randall Knight's research-based teaching strategies, Trowbridge & McDermott's foundational work on position-velocity confusion, the fundamental principles approach of Chabay and Sherwood, and Lewis Carroll Epstein's Thinking Physics.

The result is a "trap-first" methodology — one that identifies exactly where students go wrong, uses cognitive conflict to destabilize the misconception, and then rebuilds understanding from first principles. We're building diagnostic tools for this across IB, AP, A-Level, and GCSE Physics — starting with motion & kinematics and Newton's laws.

Diagnosis Before Teaching

You can't fix what you can't see. Every diagnostic maps the specific misconceptions a student holds — not just a score, but a roadmap for targeted intervention.

Research Over Opinion

Every trap we document, every diagnostic question we write, every intervention we design is grounded in published physics education research.

Conceptual, Not Procedural

Formulas are tools, not understanding. We build the intuition that makes formulas meaningful — so students know why they work, not just how to plug in numbers.

Teacher-Facing

Our diagnostics are built for physics teachers. The heatmap, cohort summary, and remediation guidance are designed to inform teaching decisions — not just produce data.
