Adaptive Language Learning System with Targeted Repetition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing language learning systems struggle to effectively regulate the review of learned material, as students find it difficult to estimate familiarity with words and grammatical rules, and lack a comprehensive approach to enhance learning by practicing words and rules in authentic contexts.
Innovation Solution
A computer-based language learning system employing targeted repetition and reinforcement, where practice-sentences are dynamically adjusted based on student responses, with intervals varying based on correctness and difficulty, and targeted reinforcement is provided to drill specific aspects of rules and words previously mishandled, ensuring nuanced and efficient language learning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If spaced repetition is used to review learned material, then learning retention is improved, but learning efficiency decreases due to lack of contextual practice
Solution Approach 1:
The patent combines spaced repetition with contextual sentence practice by merging isolated word review with authentic language contexts. Practice sentences are constructed to include target words at optimally spaced intervals while maintaining natural linguistic context, allowing simultaneous retention improvement and efficiency enhancement.
Solution Approach 2:
The patent adds the dimension of contextual authenticity to the traditional spaced repetition framework. Instead of reviewing words in isolation across time intervals, the system embeds words within practice sentences that provide semantic context, grammatical structure, and authentic usage patterns, thereby enhancing both retention and learning efficiency.
2Measurement precision
If words and rules are practiced in isolation, then individual element mastery is improved, but overall language proficiency deteriorates due to lack of contextual integration
Solution Approach 1:
The patent merges isolated element practice with contextual sentence practice by constructing practice sentences that incorporate multiple target words and grammatical rules. This allows students to master individual elements while simultaneously learning their integration into authentic language structures, thereby improving both precision and adaptability.
3Device complexity
If uniform repetition intervals are used for all words, then system simplicity is maintained, but learning optimization deteriorates due to lack of individualized adjustment
Solution Approach 1:
The patent implements dynamic repetition intervals that automatically adjust based on individual student performance. The system monitors mastery levels for each word and rule, then modifies spacing intervals accordingly—extending intervals for mastered elements and reducing them for struggling areas. This dynamic adaptation optimizes learning efficiency while maintaining manageable system complexity through automated algorithms.
4Reliability
If practice sentences include only known words, then contextual learning is improved, but vocabulary expansion deteriorates due to limited exposure to new material
Solution Approach 1:
The patent applies local quality by creating practice sentences with differentiated word familiarity levels. Most words in a sentence are known to provide contextual support, while one or two strategically selected new words are introduced. This localized mixture of familiar and novel elements enables contextual learning while simultaneously expanding vocabulary through controlled exposure to new material.

AI summary
A computer-based language learning system uses targeted repetition to familiarize a student with words and language governing rules. Targeted repetition presents practice-sentences made up of specific words and rules the language learning system has targeted for practice, with the intervals between encounters of targeted words and rules varying based on prior incorrect, correct and partially correct responses to the rule-items. Targeted reinforcement determines manner of response to practice-sentences. Learning records for each word and rule track information used in calculating an up-to-the-moment ‘need to practice’ rating for the rule-item. Learning records also track each prior response to the item, allowing the language learning system to determine the aspects of the word or rule-item of which a student lacks mastery. The language learning system provides targeted reinforcement by drilling the student on the particular aspect of the rule needing practice, along with the practice-sentence incorporating it.
