Solution Overview

Problem

Current methods for improving grammatical skills, such as filling in blanks or defining synonyms and antonyms, are manually compiled and lack adaptive testing, potentially giving users a false sense of understanding and not ensuring mastery of vocabulary, as they do not adapt to individual comprehension levels or provide follow-up testing.

Innovation Solution

An adaptive learning system that automatically generates questions and answer choices from designated sentences or words, adapts future questions based on user selections, and tracks progress through a series of rounds, using techniques like part-of-speech tagging, boilerplate removal, and quality scoring to provide tailored vocabulary learning and testing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If manual compilation of fill-in sentences and vocabulary tests is used, then questions can be created, but the process is tedious and time-consuming

Engineering Contradiction:
Improvequestion generation efficiencyVSAvoidtime for manual compilation
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The system automatically generates fill-in sentences and vocabulary questions by processing input text through part-of-speech tagging, sentence quality scoring, and automated question template application, eliminating the need for manual compilation while maintaining question quality

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The manual mechanical process of creating questions is replaced with an automated computational system that uses natural language processing, quality scoring algorithms, and adaptive testing logic to generate and deliver vocabulary assessments

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Measurement precision

If traditional static tests are used, then vocabulary knowledge can be assessed, but users may get a false sense of understanding without mastering the words

Engineering Contradiction:
Improvevocabulary comprehension accuracyVSAvoidmastery verification
Core Design Contradiction:
Measurement precisionVSReliability

Solution Approach 1:

The system implements adaptive feedback mechanisms where test results immediately influence subsequent question selection, providing continuous feedback on user comprehension and adjusting the testing strategy to ensure genuine mastery rather than superficial recognition

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The testing system transitions from a static, one-size-fits-all approach to a dynamic adaptive system that continuously adjusts question difficulty, type, and focus based on real-time assessment of user performance and comprehension depth

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If uniform testing is applied to all users, then implementation is simple, but the system cannot adapt to individual vocabulary comprehension levels

Engineering Contradiction:
Improveadaptive learning capabilityVSAvoidtesting system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system adapts to individual users by dynamically changing testing parameters including question difficulty level, question type distribution, and topic focus based on each user's demonstrated comprehension level and performance patterns

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The system performs preliminary analysis of user performance early in the testing process to establish baseline comprehension levels, then uses this information to pre-configure the adaptive testing strategy for subsequent questions

Inventive Principle:
Principle #10Preliminary action

AI summary

An adaptive learning system and method provides for automatically generating question types to a user for word comprehension and selecting multiple choice answers for display. Questions are developed for the user by obtaining online content and indexing the content into individual sentences and questions. The system provides questions in a series of rounds to the user and then adaptively tracks the progress of the user based on the categorization of each question.
