FullProof

Evolution of an E-learning App for Geometry in High Schools

FullProof is an educational platform for teaching geometry and trigonometry through structured proof writing. As UX and product lead, I guided the platform from pilot to commercial success - spearheading major redesigns of its core learning interface, improving user outcomes, and helping scale the platform across schools.

Overview

From educational pilot to market-leading platform

Guided educational platform’s transformation from pilot phase to commercial success through strategic product leadership and UX expertise. Championed comprehensive redesign of proof writing system while orchestrating collaboration between development teams, educators, and regulatory bodies. Consistently delivered improvements in learning outcomes and user satisfaction.

Personas

As a learning app the main roles are high school students and math teachers.

Noam

Student

I didn’t do my homework because I didn’t know how to begin.

Background

  • 9th grader in an advanced math track
  • Transferred to this group a month ago

Needs

  • Help remembering geometric theorems
  • Homework support

Motivations

  • Being accepted to computer science
  • Completing math homework quickly

Concerns

  • Low confidence in geometry
  • Homework takes too long

Maya

Teacher

Checking students work in geometry is so exhausting that most get feedback only in exams.

Background

  • 30 years teaching math
  • Regularly attends PD workshops

Needs

  • Quick ways to check understanding
  • Track student progress

Motivations

  • Engaging students in class
  • Preparing students for high school level work

Concerns

  • Student resistance to change
  • Already high workload

User Feedback Analysis

Data was gathered from multiple informationchannels:

  • Support tickets & CS conversations
  • Field studies in schools
  • Feedback from teacher training
  • Teacher and student surveys

Evolution of the Proof Page

Three iterative redesigns driven by user feedback and learning behavior

The Proof Page is the core of the FullProof experience. As usage scaled and feedback increased, we led two major redesigns to balance structure, flexibility, and clarity—without disrupting classroom workflows.

Initial Design (V1)

This version established the core functionality but created cognitive overload due to layout constraints and dense interaction zones.

  • Chat for submitting and hints
  • Adding solution steps from table cells only
  • 1 table structure
  • Question info in top banner
  • Feedback in tooltips

Learning Curve (V2)

Changes in Version 2 helped reduce screen clutter and introduced more structured guidance, but still relied heavily on table-based actions.

  • Side menu for submitting and hints
  • 2 table structures
  • No question info in top banner
  • QED mark added automatically
  • Feedback in table

Final Redesign (V3)

Version 3 integrated diagram-based interaction and fine-tuned the interface for mobile compatibility and classroom pacing.

  • Submitting and hints below each item
  • Option to add solution steps from diagram
  • 3 table structures
  • Improved theorem findability
  • Solution sharing option for teachers

Results

Better usability and new features based on user needs

  • 85% drop in support tickets → indicating clearer interactions and better onboarding
  • Increased user satisfaction → based on CSAT scores and qualitative feedback
  • Increased sales → helped the platform secure additional school adoptions

Key Insigts

  • Iterative redesign, anchored in real classroom feedback, enabled steady improvement without overwhelming users.
  • Cross-functional alignment between UX, pedagogy, and policy ensured features were both usable and useful.
  • Proof-writing requires balancing structure and flexibility; diagram interactions were key to bridging that gap.
