Digital Learning Infrastructure

The implementation idea

Digital learning infrastructure is the shared technical foundation on which computer-based education, digital literacy and selected vocational courses can operate.

The project aims to provide institutions with a consistent, maintainable arrangement for computers, software, connectivity, classroom management and technical support. Rather than designing every installation independently, participating locations could use common specifications and deployment procedures wherever their requirements are similar.

The emphasis is on reliable infrastructure that supports a defined learning purpose. A computer should be selected for the applications and activities it must support. Network equipment should be selected for the teaching and operational functions it needs to enable. Software should be installed because it serves a curriculum or administrative purpose, not simply because it is available.

The proposed approach favours appropriate, reliable equipment, open-source software where suitable, standardised configurations and repeatable maintenance procedures. These choices can reduce avoidable costs and simplify support, but they do not eliminate the need for funding, competent technical staff or replacement planning.

This project is a proposed implementation model. It does not imply that a standard infrastructure package has already been procured, deployed or made available to partner institutions.

Why standardisation matters

When every institution chooses its own hardware, operating system, software and installation method, the resulting environment becomes difficult to support consistently.

A technical problem at one location may require a different solution from the same problem elsewhere. Staff must learn different configurations, software updates become harder to coordinate, and replacing a failed machine may involve repeating much of the original installation work.

A standardised approach can reduce this complexity by establishing:

• A small set of approved hardware configurations.
• A defined operating system and software baseline for each intended use.
• Repeatable installation and configuration procedures.
• Consistent network and classroom-management arrangements.
• Documented troubleshooting and maintenance practices.
• A process for updating the approved configuration without disrupting learning.
• Clear responsibility for technical support, repairs and equipment replacement.

Standardisation should not mean forcing every type of facility to use identical equipment. A school computer classroom, a vocational electronics workshop and a digital-services training centre may have different requirements. The aim is to standardise within appropriate equipment profiles and use cases.

Infrastructure components

The implementation plan should cover the full technical environment rather than treating computers as an isolated procurement item.

1. Computing devices

The hardware specification should reflect the intended learning activities, software requirements, expected usage and available support capability.

For general digital learning, suitable refurbished x86-64 computers may be more economical than purchasing new equipment, provided that the devices are reliable, supportable and adequate for the intended workload.

The Haflong school IT classroom specification proposes the following characteristics for its computer pods:

• SSD storage.
• At least 4 GB RAM, with 8 GB preferred.
• Gigabit Ethernet.
• Reliable keyboard and mouse.
• A monitor of 19 inches or larger where affordable.

These are proposed baseline characteristics for that particular classroom model, not universal minimum specifications for all courses. More demanding software or specialist vocational activities may require a different configuration.

Equipment should be evaluated for condition, compatibility, power requirements, repairability, availability of replacement parts and expected service life. Very old or unsupported equipment should not be selected merely because it is free.

2. Operating system and standard software

For the Haflong school classroom example, the proposed standard operating system is Linux Mint Xfce. The purpose is to provide a consistent, lightweight environment suitable for the selected hardware and educational applications.

The proposed classroom software includes:

The final software list should be controlled and documented. Every application should have a clear learning or operational purpose.

Students do not need to study operating-system administration merely because Linux is used to run the classroom. The operating system is part of the infrastructure; the curriculum should focus on the digital and technical capabilities learners are expected to develop.

Other centre types may need different software. A vocational course involving specialist equipment or applications should define those requirements separately and confirm compatibility before procurement.

3. Wired network and connectivity

A wired local area network can provide a stable foundation for a computer classroom. In the Haflong example, wired Ethernet is proposed for classroom computers, with Wi-Fi available where useful for other devices.

The local network can support:

• Internet access where connectivity is available.
• Distribution of the teacher’s screen to learner computers.
• Classroom-management functions.
• Distribution of learning materials.
• Collection of student work.
• Local administration and technical support.
• Future local learning services where they are separately designed and implemented.

The infrastructure specification should include network switches, structured cabling, router requirements, cable management and suitable power distribution. Cables should not create hazards in student movement areas, and computers should not be placed where they are vulnerable to damage.

Internet availability and local network availability are different requirements. A centre should determine which activities depend on an external connection and which can continue using locally available materials when connectivity is interrupted.

4. Power, furniture and physical arrangement

Computers and network equipment need a safe, practical physical installation. Power distribution, cable routing, ventilation, equipment placement and access for maintenance should be considered before installation.

The Haflong design deliberately avoids requiring expensive specialist computer-lab furniture. It proposes using ordinary school benches where practical and positioning computers and monitors so that equipment remains accessible without occupying student foot space.

The layout must also allow a trainer to supervise the class, enable learners to use the equipment correctly and provide space for related non-computer activities.

Other facilities may need different furniture or environmental controls, particularly where practical tools, specialist equipment or other safety-sensitive activities are involved.

The standard system image

One of the central proposals in the Haflong specification is to maintain a standard, versioned classroom system image.

A system image is a prepared installation containing the approved operating system, software, configuration and standard learning environment. It can be used to restore or deploy compatible computers without manually configuring each device from the beginning.

A standard image may contain:

• The approved operating system.
• Required productivity, browser and programming software.
• Approved educational applications.
• Desktop settings and shortcuts.
• Classroom-management configuration.
• Security settings.
• Required fonts and printer support.
• The standard student environment.

Machine-specific settings, such as hostname, machine identity, network configuration and classroom-management identity, must be applied separately where required.

The project proposes using Clonezilla as a starting point for disk imaging. Larger deployments may later use network-based imaging where the scale and operational requirements justify it.

A controlled image process should include version identification, testing, backup, deployment instructions and a record of changes. For example, an image might progress through versions such as Haflong-IT-Image-v1.0 and Haflong-IT-Image-v1.1.

An updated image should be tested before widespread deployment. The objective is to make installations repeatable without introducing the same fault or unsuitable configuration across every computer.

Classroom management and shared computer use

The infrastructure should support the teaching model rather than dictate it.

In the Haflong classroom design, 40 students are organised into 10 pods, with one computer per four students. Each pod contains two pairs of students who rotate between computer work and a related activity.

This arrangement depends on the room layout, prepared learning activities, teacher instructions and classroom-management capability. The computer is shared, but every learner should have a defined task throughout the lesson.

The proposed use of Veyon and a wired network supports teacher demonstrations and classroom supervision. The teacher’s screen can be displayed on learner monitors during instruction, while each pod can use its own computer during practical work.

The infrastructure must be tested against the intended classroom routine. Screen sharing, computer identities, user access, file distribution and recovery from common problems should be checked before learners begin using the facility.

The equipment design should also consider what happens when one computer fails. The operating plan should explain how the class continues, how the fault is reported and who is responsible for repair.

Installation and deployment process

A repeatable deployment process helps avoid inconsistent configurations and reduces the technical work required at each location.

The proposed process is:

1. Assess the site. Confirm the intended learning activities, equipment count, power, network, room layout and available technical support.
2. Approve the configuration. Select compatible hardware and define the software, network and security baseline.
3. Prepare the master system. Install and configure the approved operating system and applications on a representative computer.
4. Test the master image. Verify required applications, network functions, classroom-management behaviour, security settings and learning tasks.
5. Deploy to compatible devices. Use the approved imaging procedure, then apply machine-specific identities and settings.
6. Validate each installation. Confirm that every device boots, connects, runs the required applications and performs its intended role.
7. Document and hand over. Record device identities, configuration versions, known limitations, maintenance procedures and responsible contacts.

The deployment process should include acceptance criteria. A computer should not be considered ready simply because the operating system starts. It must perform the activities for which it was procured and configured.

Maintenance and technical support

Infrastructure remains useful only when it can be maintained. The implementation plan should establish responsibility for routine checks, fault reporting, repairs, updates and replacement.

Routine support

Depending on the installation, routine work may include:

• Checking computers, monitors, keyboards and mice.
• Inspecting cables and power connections.
• Confirming network connectivity and classroom-management functions.
• Applying approved updates.
• Checking storage and system health.
• Restoring the standard image when necessary.
• Maintaining backups of required configuration and learning resources.
• Recording faults, repairs and equipment changes.

A school-based lab assistant may handle routine startup, shutdown, basic user assistance and fault reporting when appropriately prepared. More complex technical work should be assigned to a person with the necessary competence.

Fault management

The operating model should define how a fault is reported, who assesses it, what work can be done locally and when specialist support is needed.

A useful record identifies the affected device, the reported problem, the action taken, any parts required and whether the equipment has returned to service. This creates a basis for identifying recurring problems and planning replacement.

Updates and configuration control

Operating-system and application updates should be managed in a way that maintains security without unexpectedly disrupting teaching.

The approved configuration should be documented and versioned. Significant changes should be tested on a representative device before being applied across a wider deployment.

Where devices operate with limited internet access, the support plan should specify how updates, software packages and learning resources will be obtained and transferred safely.

Offline-tolerant learning

Some participating locations may have unreliable or expensive connectivity. The infrastructure design should distinguish between functions that require the internet and those that can be delivered locally.

Depending on the course, possible measures include:

• Locally stored learning materials.
• Printed practice activities where appropriate.
• Local copies of approved software installers and system images.
• Local storage and collection of learner work.
• A documented process for synchronising records when connectivity returns.

The wider learning framework envisages online-first delivery that tolerates offline conditions, with local caching or synchronisation where appropriate. The exact approach must be designed and tested for the selected learning platform and environment.

Offline operation should not be assumed to work automatically. The project must identify which content, records and activities remain available, what happens when data must be synchronised and how conflicting or incomplete updates are handled.

Partner roles and responsibilities

Several organisations may contribute to digital learning infrastructure. Their roles should be agreed according to the installation and the capabilities they can provide.

A single organisation may fulfil several roles if it has the appropriate capability. The project should nevertheless name who is accountable for each responsibility.

Wara KarmaYoga Foundation may contribute to the educational purpose, community coordination or programme development within an agreed charitable scope. Wara Systems may provide separately agreed commercial technology or implementation services. Neither role should be assumed without a project-specific arrangement.

Local Partner may be considered as a potential collaborator where there is mutual interest and formal agreement. Its premises, personnel, funding or technical resources must not be treated as committed in advance.

The project should also define ownership of equipment, software and documentation, the rights to use the standard system image, access to administrative credentials, data protection responsibilities and the process for handover if a partner changes.

Procurement and cost planning

The project budget should cover the complete installation and its expected operating needs rather than only the purchase price of computers.

Relevant cost categories may include:

• Computers, monitors and peripherals.
• Network switches, routers, cabling and installation.
• Power distribution and any necessary electrical work.
• Furniture, mounting and cable-management materials.
• Software configuration and deployment.
• Site testing, documentation and staff orientation.
• Connectivity and recurring utilities.
• Maintenance, repairs, spare parts and replacement equipment.
• Technical support and approved updates.

Refurbished equipment may lower initial costs, but its condition and expected service life must be assessed. A lower purchase price may not be economical if the equipment fails frequently, cannot run the required software or is difficult to repair.

The budget should state which items are donated, contributed in kind, purchased or maintained by a partner. It should also identify who will pay recurring costs after the initial installation funding is exhausted.

A project should not proceed to procurement until the intended use, technical specification, site readiness, budget and maintenance responsibility have been agreed.

Security, privacy and responsible use

The infrastructure must be configured to support safe use and protect institutional and learner information.

The implementation plan should address:

• Appropriate user accounts and access permissions.
• Administrative credential control.
• Approved software installation and update procedures.
• Safe browsing and responsible use of online services.
• Protection of learner records and submitted work.
• Backup and recovery arrangements for information that must be retained.
• Physical security and safe handling of equipment.
• Procedures for reporting suspected misuse, data exposure or technical incidents.

Classroom-management tools should be configured for legitimate teaching and administration. Access to learner devices or records should be limited to authorised purposes and handled in accordance with the host institution’s policies and applicable requirements.

A standard image is not a substitute for ongoing security management. Installed software, configurations and access arrangements must be reviewed as the environment changes.

Measures of implementation success

The project should evaluate both installation quality and continued usefulness.

Possible measures include:

Targets should be established after the project scope and baseline are known. Reporting should distinguish a completed installation from a facility that remains usable over time.

Readiness before deployment

Before infrastructure is installed for a participating institution, the implementation team should confirm the following.

• The learning purpose and intended applications are defined.
• The site, power, room layout and connectivity have been assessed.
• The hardware and software configuration has been approved.
• Equipment is compatible, supportable and suitable for the intended workload.
• Network, security and classroom-management requirements are documented.
• A tested master configuration and deployment procedure are available where imaging is used.
• Technical support, maintenance and repair responsibilities are assigned.
• Equipment ownership, administrative access and documentation handover are agreed.
• The installation and recurring operating budget is approved.
• Acceptance tests and post-installation review arrangements are defined.

If these requirements are not met, the project should remain in preparation until the gaps have been addressed.

Discuss an infrastructure project

A school, community institution, training provider, technology company or funding organisation can begin by identifying the learning environment it wants to establish or improve.

The initial discussion should cover the location, intended users, existing equipment, required learning activities, current technical limitations, resources available and support still needed.

The next step is a site and requirements assessment, followed by an agreed technical specification, cost plan, division of responsibilities and implementation schedule.

The objective is not to deploy the largest possible quantity of equipment. It is to create a technical environment that supports the intended learning activities reliably, can be maintained by identifiable people and remains useful after the initial installation is complete.
