Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing learning support systems fail to effectively evaluate a learner's understanding and proficiency by measuring the duration required for handwriting mathematical or chemical formulas in a step-by-step answer process, which is crucial for identifying areas of improvement.
Innovation Solution
A learning support system that includes a processor to obtain timekeeping information during handwritten input of formulas and displays the duration required for each step of the answer process, highlighting durations exceeding a threshold and providing feedback for improvement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If timekeeping information is obtained for each step of handwritten answer input, then measurement precision of learner's understanding is improved, but device complexity increases
Solution Approach 1:
The patent segments the answer input process into multiple steps (e.g., thinking step, writing step) and measures time for each segment separately. This segmentation enables precise measurement of learner's understanding at different stages without requiring complex overall system changes, as each time measurement module operates independently on its specific timekeeping function.
2Loss of information
If duration display is provided for each answer step, then information completeness for learner feedback is improved, but ease of operation deteriorates
Solution Approach 1:
The patent applies local quality by displaying duration information specifically at relevant locations (near each answer step) rather than presenting all information uniformly. The display shows thinking time and writing time in context with their corresponding answer steps, making the information complete and meaningful while maintaining ease of operation through localized, contextual presentation.
3Measurement precision
If detailed timekeeping is implemented for handwritten input, then evaluation accuracy of learner proficiency is improved, but productivity of answer input process deteriorates
Solution Approach 1:
The system implements self-service by automatically obtaining timekeeping information without requiring learner intervention. The timing modules automatically start and stop timing for each answer step, and the display automatically presents duration information, eliminating manual input requirements and maintaining high productivity while achieving accurate evaluation.
Data Source
AI summary
A learning support system includes, an operator; a display; and at least one processor. The at least one processor obtains timekeeping information in a case in which an answerer inputs by handwriting through the operator an answer including a mathematical formula or a chemical formula in a step-by-step answer process leading to a final answer. In a case in which the answer handwritten by the answerer is displayed on the display as a handwritten input image, the at least one processor controls the display to display a length of a duration required for the answerer to input by handwriting the answer process in a state associated with each step of the answer process.
