Problem-State Answer Display Control for Online Learning Integrity

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

In online learning support systems, there is a risk of fraud acts occurring when learners can easily access correct answers by duplicating browser logins, compromising the integrity of the learning process.

Innovation Solution

Implementing a control mechanism that prevents the display of correct answers on the user terminal when a specific electronic label is detected, ensuring that the correct answer is not visible during the input of answers to problems.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If correct answers are displayed on the display unit when problems are shown, then learners can easily view solutions, but fraud acts can be easily executed by accessing content including problems through duplicate browser logins

Engineering Contradiction:

Improveease of viewing solutionsVSAvoidintegrity of learning process

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The system applies preliminary anti-action by detecting the display state of problems and proactively preventing the display of correct answers when problems are detected on the display unit. The control unit monitors for problem content and blocks answer display in advance, preventing fraud before it can occur rather than reacting after detection

Inventive Principle:

Principle #9Preliminary anti-action

Solution Approach 2:

The control unit acts as an intermediary between the problem display system and the answer display function. It intercepts the answer display request and conditions its execution on the absence of problem content on the display unit, thereby mediating between the learner's need to view answers and the system's need to prevent fraud

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If multiple browsers are allowed to access the learning system simultaneously, then learners can use the system flexibly on different devices, but correct answers can be accessed through duplicate login to view problems

Engineering Contradiction:

Improveflexibility of system accessVSAvoidfraud risk

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The system implements feedback by continuously monitoring the display unit for problem content and using this information to control answer display permissions. The control unit receives feedback about what is currently displayed and adjusts its behavior accordingly, allowing simultaneous browser access while preventing fraud through real-time display state monitoring

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system adds a new dimension of control by introducing display state monitoring as an additional condition for answer display. Rather than simply allowing or blocking answers based on login status, the system evaluates the dimensional state of what is currently being displayed, adding a spatial/temporal dimension to the access control logic

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

AI summary

An information processing apparatus (2) includes a processor. The processor does not output data for displaying predetermined content in response to detecting a request for displaying the predetermined content and in response to satisfying a first condition that a problem generated from the predetermined content is displayed on a display unit (303) or a second condition that an answer to the problem generated from the predetermined content is not received.
