Checking Question Generation for Incorrectly Answered Questions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing study methods do not effectively generate and provide questions with correct answers or incorrect answers as choices for learners to review their incorrectly answered questions, limiting the efficiency of self-directed learning.
Innovation Solution
A device and method that select incorrectly answered questions, extract correct or incorrect answers as choices, and generate checking questions to allow learners to study these answers, minimizing the number of questions needed to review all incorrectly answered questions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If all incorrectly answered questions are reviewed individually, then the user can study each incorrect answer in detail, but the study time and number of questions to be reviewed increases significantly
Solution Approach 1:
The patent combines multiple incorrectly answered questions into a single integrated checking question. The checking question includes several choices, each corresponding to the correct answer of a different incorrectly answered question. By answering one checking question, the user simultaneously reviews multiple incorrect answers, merging what would otherwise be separate study tasks into one efficient activity.
Solution Approach 2:
The checking question serves multiple functions simultaneously: it acts as a review tool for multiple incorrectly answered questions, provides self-assessment capability, and generates study material dynamically based on user performance. This multi-functional design eliminates the need for separate review processes for each incorrect answer.
2Productivity
If checking questions are generated with extracted correct and incorrect answers as choices, then the number of questions needed for review is minimized, but the complexity of question generation increases
Solution Approach 1:
The system automatically generates checking questions by extracting correct and incorrect answers from the user's own incorrectly answered questions. The generation process is self-service in nature, using the user's performance data to create personalized review material without requiring external intervention or complex manual design.
Solution Approach 2:
The checking question structure copies the essential elements (questions and answers) from the original incorrectly answered questions, reorganizing them into a new format. Rather than creating entirely new content, the system replicates and rearranges existing educational material to serve the review function.

AI summary
Disclosed are a device and method for providing a checking question designed to allow a user to perform the checking study of correct answers or incorrect answers by using the choices of one or more incorrectly answered questions. The device includes: an incorrectly answered question selection unit which selects one or more questions incorrectly answered by a user from among questions provided to the user; a choice extraction unit which extracts correct answers as choices for the respective selected incorrectly answered questions; a checking question generation unit which generates one or more checking questions designed to allow the user to study the incorrectly answered questions by allocating the extracted choices so that the extracted choices become the choices of the checking questions; and a checking study provision unit which provides the study of the incorrectly answered questions by transmitting the generated checking questions to a user terminal.
