What’s New

Adaptive Pre-Test with ZPD Analysis 🎯

Your learning journey now begins with a powerful diagnostic engine that ensures your course is neither too easy nor too hard—it’s perfectly calibrated to your current knowledge.

🧬 Deep Diagnostic Journey Real-time interim analysis tracks your understanding as you progress, culminating in a ZPD (Zone of Proximal Development) Analysis.

• The Feature: Visualizes your knowledge landscape with clear divisions: “Known Concepts,” “Concepts to Learn,” and a personalized “Recommended Learning Path.”
• New: Pre-test questions now include an “I Don’t Know” option, allowing you to accurately signal uncertainty rather than guessing—resulting in a more precise diagnostic profile.
• The Science: Based on Vygotsky’s ZPD, we identify the optimal zone between what you know and what you can learn next—maximizing growth while preventing cognitive overload. Honest self-assessment prevents false positives that could create knowledge gaps later.

🎛️ Total Curriculum Control Take command of your learning experience.

• The Feature: Select or deselect “Known Concepts” to review or skip material. Add custom concepts manually to address specific learning gaps.
• The Benefit: Learn exactly what you need, when you need it—no wasted time on mastered material.

⚙️ Precision Generation We use your ZPD profile to generate a curriculum tailored specifically to your readiness level, maximizing efficiency by focusing only on material within your optimal learning zone.

Streamlined Learning Flow ⚡

Auto-Play Next Stay in the learning zone without interruption.

• The Feature: The next video segment automatically plays immediately after you complete a segment quiz.
• The Benefit: Maintain momentum and flow state, reducing friction and context-switching costs.
• The Science: Supports Flow Theory by eliminating disruptions during deep learning sessions.

Skip to Quiz Already confident in the material? Prove it.

• The Feature: New “Skip to Quiz” button lets you bypass the video and jump straight to the assessment.
• The Benefit: Respect your time and prior knowledge—test out of material you’ve already mastered.
• The Science: Honors Competency-Based Learning by letting demonstrated mastery, not seat time, drive progression.

Key Improvements & Fixes

🔧 Fixed: Stale Questions in Practice Quiz We resolved a critical issue where questions from the previous video would sometimes persist in the practice tab. The quiz now reliably refreshes to match the current segment immediately after you finish watching, ensuring your practice is always relevant.

🎓 Smart Completion Flow Finishing the final segment now correctly transitions you to the Mastery Challenge instead of attempting to load a non-existent “next video.”

✅ Quiz Accuracy Guarantee We’ve implemented a new backend validation layer to ensure every multiple-choice question matches its explanation perfectly. This eliminates “correct answer” mismatches and guarantees 100% reliable testing—because trust in the assessment is fundamental to learning.

⏱️ Precise Note Timestamps Notes now display the absolute video timestamp (e.g., 5:04) instead of relative time, making it effortless to jump back to the exact moment you captured an insight or question.

🔀 Smarter Randomization Answer options are now fully randomized across retrieval prompts, interpolated tests, and flashcards to prevent pattern guessing and shallow memorization, while strictly maintaining the integrity of correct answers and their explanations.
