Solution Overview

Problem

Existing electronic learning systems lack the ability to dynamically control the presentation duration of subject matter, queries, and response mechanisms based on user input, which limits personalized learning experiences and accurate competency measurement.

Innovation Solution

A computing device is programmed to retrieve and present question items with controlled presentation durations for subject matter, queries, and response mechanisms based on user input, and to calculate user competency measures based on response accuracy and completion time, automatically selecting question items for repeated presentation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the system presents all question item components (subject matter, query, response mechanism) simultaneously with fixed duration, then the system operation is simple, but the system cannot provide personalized learning experiences or accurately measure user competency

Engineering Contradiction:

Improvepersonalized learning experienceVSAvoidsystem complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system dynamically adjusts the presentation duration of each question item component (subject matter, query, response mechanism) based on user input and real-time performance data. This allows the same system to adapt to different learning speeds and styles without requiring multiple fixed-duration system configurations, resolving the contradiction between adaptability and complexity.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system changes the time parameter (presentation duration) of question item components based on user performance metrics such as response accuracy and completion time. By dynamically modifying this parameter, the system provides personalized learning experiences while maintaining a unified system structure, avoiding the need for multiple complex fixed-duration configurations.

Inventive Principle:

Principle #35Parameter changes

2Measurement precision

If the system uses fixed presentation duration for all components, then the system structure is simple, but the competency measurement accuracy is insufficient

Engineering Contradiction:

Improveuser competency measurement accuracyVSAvoidpresentation control complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The system uses user performance feedback (response accuracy and completion time) to dynamically adjust the presentation duration of question item components. This feedback loop enables accurate competency measurement by adapting the presentation timing to each user's actual processing speed, while the automated feedback mechanism prevents excessive complexity in the control system.

Inventive Principle:

Principle #23Feedback

3Adaptability or versatility

If the system dynamically adjusts presentation duration based on user input, then personalized learning is enabled, but the system requires more complex control mechanisms

Engineering Contradiction:

Improvedynamic adaptation to user needsVSAvoidsystem operation simplicity

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system automatically adjusts presentation durations based on user performance data without requiring manual intervention or complex configuration. The system serves itself by using its own collected performance metrics to dynamically optimize the presentation timing, maintaining ease of operation while achieving high adaptability.

Inventive Principle:

Principle #25Self-service

4Loss of time

If the system presents components simultaneously, then the presentation is straightforward, but the system cannot track individual component engagement time

Engineering Contradiction:

Improvetracking of component presentation timeVSAvoidpresentation sequence control complexity

Core Design Contradiction:

Loss of timeVSDevice complexity

Solution Approach 1:

The system segments the question item into distinct components (subject matter, query, response mechanism) and tracks the presentation duration of each component separately. This segmentation enables precise time tracking for competency measurement while the automated segmentation process prevents excessive complexity in the control mechanism.

Inventive Principle:

Principle #1Segmentation

AI summary

A question item comprising: textual, visual or auditory subject matter; a query or instruction pertaining to the subject matter; and a representation of a response mechanism for receiving a user response to the query or instruction, may be retrieved from a data store. The subject matter, query or instruction and response mechanism may be presented in a presentation sequence, wherein a presentation duration of each of the subject matter, query or instruction and response mechanism is controlled by user input. Based on the user input, a presentation duration of each of the subject matter, query or instruction, and response mechanism may be determined. Each of the three presentation durations may be stored. A completion time may be determined based on one or more of the presentation durations and may be stored along with response accuracy, for use in calculating a user competency measure for the question item. An algorithm for advancing through an electronic learning curriculum comprising multiple question items may also be provided.
