Features of development in the EdTech domain

Specific requirements in EdTech

Adaptability and Accessibility

In EdTech, one of the key requirements is to create platforms that are easily adaptable to different user needs. This could mean integrating multilingual interfaces, creating versions for visually or hearing impaired users, and so on.

More details can be found in the WCAG specifications.

Personalization

Personalization in EdTech is often achieved through the use of machine learning algorithms that analyze user behavior and provide personalized content or learning paths.

Security Issues in EdTech

Data protection

• Encryption: Uses on-the-fly and on-disk data encryption to protect information from unauthorized access. It is recommended to use strong encryption algorithms, for example, AES-256.
• Two-factor authentication (2FA): This mechanism provides a second layer of security after entering your password, significantly reducing the risk of unauthorized access.
• Monitoring and auditing: monitoring and auditing systems to track all data operations and the ability to recover them in the event of an incident.

Аутентификация и авторизация

EdTech platforms usually have different levels of access: for students, teachers, and administrative staff. Each of these groups has its rights and restrictions that need to be established.

Technical Aspects:

• Role-Based Access Control (RBAC): Systems often use role-based models to manage different access levels. For example, students can view and complete assignments, teachers can create and grade assignments and administrators can manage the entire system.
• OAuth and SSO (Single Sign-On): These technologies allow users to use a single profile to access various services, simplifying the authentication process, but require special care in storing access tokens.
• Security Policies: To define which operations are available on certain objects, ACL (Access Control Lists) or other security policy mechanisms can be used.

Regulation in EdTech

Regulation in EdTech is an important aspect that has a direct impact on the development and operation of educational technologies. Because this domain frequently interacts with sensitive data, such as student and faculty personal information, regulatory requirements for data security and privacy in this domain are particularly high.

Legislation

Different countries have different laws governing EdTech. In the US, for example, this is FERPA (Family Educational Rights and Privacy Act), a law protecting the confidentiality of student records. In the European Union, the General Data Protection Regulation (GDPR) applies.

Safety Standards

There are also security standards, such as ISO/IEC 27001, which set requirements for information security management systems (ISMS). These standards can be applied to EdTech platforms to ensure a high level of data protection.

Certification

Some educational products must undergo a certification process to be approved for use in educational settings. This can be either state accreditation or international quality standards.

Technical aspects of regulation:

• Logging and Monitoring: Detailed logs of data access and usage are required to enable auditing.
• Data Loss Prevention (DLP): DLP systems prevent the leakage of sensitive data as part of data regulation requirements.
• API Security: If a platform provides an API for third-party developers, it must adhere to strict security standards such as OAuth for access tokens and Rate Limiting to prevent abuse.

Trends and future in EdTech

Microlearning и Just-in-Time Learning

Microlearning

Microlearning is a method of education where information is broken down into short, easily digestible modules. This requires the development of adaptive algorithms and user-friendly interfaces to effectively deliver material to students.

Just-in-Time Learning

Just-in-Time Learning provides information "on demand," offering relevant content when it is most pertinent for the user. This necessitates integration with other systems and solutions for quick access to needed materials.

Impact on Development in EdTech:

• Adaptive Algorithms: Both approaches require complex algorithms for personalized learning.
• Security and Privacy: It is important to pay attention to data protection, especially in Just-in-Time Learning, where access to sensitive information may be necessary.
• Performance: Systems must be capable of quickly processing requests and delivering materials, which poses a challenge for performance optimization.
• Interface and User Experience: For effectiveness, both approaches require a convenient and intuitive design.

Gamification

Gamification is the application of game mechanics and elements to non-game processes to increase their effectiveness and interest. In EdTech, this may include reward systems, points, tournaments, and so on to make the educational process more attractive and motivating.

1. Impact of gamification on development:
2. Interface Design: Gamification requires developers to create interactive and dynamic user interfaces that support game elements.
3. Analytics and monitoring: The introduction of game elements is usually accompanied by the collection of data on user behavior, which requires developed analytical tools.
4. User Adaptability: Gamification often relies on personalization, making it necessary to use machine learning algorithms to adapt to the individual needs of users.
5. Social Integration: Many gamified systems include elements of social interaction, such as leaderboards or team challenges, which require safe and effective integration of social features.
6. Security: Since gamification can involve the collection and analysis of user data, security and privacy issues become even more pressing.

Expanding the role of social networks

Social platforms are becoming a place for informal education and knowledge sharing.

How does this Impact development? The need for integration with social networks, implementation of communication and collaboration functions.

Learning through the Internet of Things (IoT)

IoT devices, such as smart boards or sensors in laboratories, can collect data to analyze and improve the educational process.

How does this Impact development? Difficulty in interacting with different types of devices, securely storing and processing data.

Artificial intelligence

AI is used to analyze large amounts of data about students and adapt educational programs to each individual. This allows teachers to focus on the complex aspects of teaching while minimizing routine work.

How does this Impact development? The a need to implement machine learning algorithms and create user interfaces that allow teachers to interpret analytical data.
