Academic Integrity & Anti-Cheating Features

Technical Excellence, Educational Focus

Our anti-cheating system has been designed with K-12 students in mind, balancing security with age-appropriate user experience. Students are never locked out for technical errors, but deliberate attempts to circumvent the system are prevented at multiple levels.

The system recognizes that not all outside help represents cheating – sometimes students need to research concepts to understand them better. However, by requiring verbal articulation and evaluating true understanding rather than just memorized words, we ensure that students engage meaningfully with the learning process.

Security Standards: OWASP 2025, FERPA Compliant, COPPA Compliant

This comprehensive anti-cheating system ensures that your assessment data reflects genuine student learning, not technical workarounds or dishonest practices. We’re proud to support your mission of fair, accurate, and meaningful student evaluation.

The Problem: Students might try to open the same lesson in multiple browser tabs to view answers in one tab while submitting them in another.

Our Solution:

• Database-Level Session Locking: When a student opens a lesson, our system creates a unique, secure session that locks that lesson to a single browser tab
• Real-Time Validation: Every answer submission is validated against the active session before being accepted
• Visual Indicators: Students see a clear “Active Session” banner showing their session is being monitored
• Automatic Blocking: If a student tries to open the same lesson in another tab, they receive a full-screen message explaining that the lesson is already active elsewhere
• Smart Recovery: If a browser crashes or closes accidentally, students can resume their session without losing progress

For Students

Normal Use (One Tab):

• Students work through lessons naturally without any interruptions
• The system operates invisibly in the background
• Scores update automatically as they progress
• They can refresh, pause, and resume without losing progress

If Multiple Tabs Are Attempted:

• The first tab works normally
• Additional tabs show a clear message: “This lesson is already open in another tab”
• Students are given clear options:
• Close the other tab and continue in the current one
• Click “Resume Here” to switch to the current tab
• Return to the course list
• No confusing error messages or technical jargon

The Problem: Students might try to use the help feature to simply ask for the answer to the current question they’re being asked.

Our Solution:

• AI-Powered Cheat Detection: When students click “Ask a Question,” our system analyzes whether they’re asking for help understanding concepts or trying to get the direct answer to a CFU question
• Concept Teaching Instead: If the system detects a student trying to get the direct answer, it responds with “It looks like that’s a specific question from this lesson” and then teaches the underlying concepts to help them understand HOW to solve it, without giving the answer
• Legitimate Help Provided: When students ask genuine educational questions about concepts, definitions, or processes (not specific answers), they receive clear, age-appropriate explanations
• Context-Aware Responses: The system knows what question the student is currently working on and detects attempts to:
  • Directly ask for the answer to the current lesson question
  • Rephrase the question to get the answer
  • Ask “what is the answer” or similar direct requests

Teacher Benefit: The help feature supports genuine learning without enabling academic dishonesty. Students still need to think through and apply concepts to answer questions.

The Problem: AI systems can sometimes “hallucinate” or incorrectly evaluate student responses, leading to unfair grading.

Our Solution:

• Consistent Grading: AI temperature set to 0.1 for maximum consistency across all student responses
• Natural Language Flexibility: Students receive credit for correct answers even if they phrase them differently than expected (90%+ content accuracy = full credit)
• Authentication Required: All evaluation requests require student authentication – no anonymous or manipulated submissions
• Rigorous AI Training: Our answer evaluation system uses extensive prompt engineering (400+ lines of instructions) to ensure the AI evaluator never:
  • Claims students said things they didn’t say
  • Marks correct answers as incorrect
  • References previous questions (each answer is evaluated in isolation)
  • Gets confused by speech recognition formatting

Teacher Benefit: Fair, consistent, and accurate grading that recognizes correct understanding even when students express it in their own words.

The Problem: Students might try to copy answers from other sources or use AI tools on other devices to generate responses they can paste into the lesson.

Our Solution:

• Voice-Only Responses: The majority of questions (13-15 out of 27-29 per lesson) require students to speak their answers out loud using their microphone
• No Copy-Paste Possible: Students cannot paste text into voice responses – they must verbally articulate their thinking
• Active Learning Required: This multi-step process means students cannot completely bypass the learning process – they must engage with, process, and articulate the content
• Engagement Even with Outside Help: Even if a student uses another AI tool or resource on a second device or phone to research an answer:
  • They must first type or speak the question into that tool (engaging with the question)
  • They must read and comprehend the response
  • They must then verbally explain it in their own words (demonstrating understanding)
  • Our AI evaluates whether they truly understand the concept, not just whether they said the right words

Teacher Benefit: Even when students seek outside help, they’re still required to process information and demonstrate verbal understanding, ensuring some learning occurs in the process.

The Problem: Students might switch to other tabs or applications and let the lesson play in the background, completing portions without actually paying attention.

Our Solution:

• Tab Visibility Monitoring: The system continuously monitors whether the lesson tab is the active, visible window
• Manual Resume Required: When the student returns to the lesson tab, they must manually click the “Resume” button to continue – the lesson does not auto-play
• Focused Learning: Students must actively pay attention to progress through the lesson
• Background Prevention: This prevents students from:
• Playing the lesson in the background while doing other work
• Multitasking during instruction time
• Gaming the time-on-task metrics
• Immediate Auto-Pause: The moment a student switches to another tab, clicks to another window, or minimizes the browser:
• All audio instruction immediately stops
• The lesson progression halts
• Any active timers pause

Teacher Benefit: Time-on-task data accurately reflects actual engagement, and students cannot passively complete lessons while doing other activities.

The Problem: Students might refresh pages or navigate backward to improve their scores by retaking questions.

Our Solution:

• First-Attempt Tracking: The system tracks which questions each student has answered and records only their first attempt for scoring purposes
• JSONB Question State Management: Each question’s state is stored in the database using advanced data structures that prevent double-counting
• Automatic Score Recalculation: If a student refreshes the page, their previous answers are restored, but scores remain based on first attempts only
• Transparent Mastery Scoring: Final scores are calculated as: (First-Attempt Correct Answers ÷ Total Questions) × 100
• Progress Persistence: All progress is automatically saved to the database every time a student answers a question

Teacher Benefit: Accurate assessment data that reflects true first-attempt mastery, not repeated attempts or score gaming.

The Problem: Students might notice patterns in answer placement (e.g., “the answer is always C”) and use this to guess rather than learn.

Our Solution:

• Balanced Distribution: Correct answers are distributed across all positions (A, B, C, D) with roughly equal frequency
• Text-Based Validation: The system stores and validates the full text of correct answers, not just letter positions, preventing manipulation
• Consistent for Each Student: Once a lesson is created, the answer order remains consistent (students who leave and return see the same order)
• Pattern Prevention: Our quality checks ensure no detectable patterns in answer placement across the 27-29 checking for understanding questions per lesson

Teacher Benefit: Students must read and understand each question carefully rather than relying on answer-position patterns.

The Problem: If teachers modify lesson content after students have started, it could invalidate saved progress or create inconsistencies.

Our Solution:

• Cryptographic Hashing: Every question is assigned a unique SHA-256 hash based on its content
• Change Detection: If a teacher modifies a question, the system automatically detects the change
• Smart Invalidation: Saved word positions and progress markers are invalidated when content changes, ensuring students always work with current content
• Fast Performance: Hash validation completes in under 5 milliseconds, maintaining smooth user experience

Teacher Benefit: Freedom to update and improve lessons while ensuring students always work with the most current version.

The Problem: Automated scripts or bots might try to scrape content or create fake student accounts.

Our Solution:

• Rate Limiting: Login attempts are limited by email and IP address to prevent brute-force attacks
• Activity Logging: All content access is logged with timestamps, user agents, and IP addresses
• Device Fingerprinting: Basic device identification helps detect unusual access patterns
• Account Blocking: Suspicious accounts can be automatically flagged and blocked
• Content Access Monitoring: The system tracks how quickly students move through content to identify bot-like behavior

Administrator Benefit: Protection against unauthorized access and content theft.

The Problem: Students might try to access other students’ work or progress data.

Our Solution:

• Row-Level Security (RLS): Database-level policies ensure students can only access their own data
• Role-Based Access: Teachers can only view data for their enrolled students; admins have broader access within their organization
• Secure API Endpoints: All data requests require valid authentication tokens
• FERPA & COPPA Compliance: Security measures align with federal student privacy requirements
• Encrypted Sessions: All session data is encrypted and validated on every request

Teacher & Administrator Benefit: Complete confidence in student data privacy and access control.

The Problem: Students might walk away from a lesson and leave it open indefinitely, or try to manipulate session timing.

Our Solution:

• Activity Tracking: The system monitors genuine user interaction (clicks, keypresses, touches)
• Heartbeat Verification: Active sessions send verification signals every 2 minutes (only when genuinely active)
• 30-Minute Timeout: Sessions automatically expire after 30 minutes of inactivity
• Hijacking Prevention: Multi-layer validation ensures session IDs haven’t been manually modified
• Comprehensive Logging: All session events are logged with detailed context for security monitoring

Teacher Benefit: Accurate time-on-task data and protection against session manipulation.

Every security-relevant event is logged with:

• Student ID
• Lesson ID
• Session ID
• Timestamp
• Failure reason (if applicable)
• Browser information
• Action taken

This creates an audit trail that administrators can review if academic dishonesty is suspected.
