Cambridge Syllabus Notes

12. IT in Society – Technology‑Enhanced Learning (TEL)

Objective

Explain how technology‑enhanced learning (TEL) works, referring to the five delivery methods specified in the Cambridge AS/A Level IT syllabus and to their impact on learners.

What is Technology‑Enhanced Learning?

Technology‑Enhanced Learning (TEL) is the use of digital tools, platforms and standards to support, deliver or augment the learning process. TEL can be:

Synchronous – real‑time interaction (e.g., video‑conferencing).
Asynchronous – self‑paced study (e.g., MOOCs, online tutorials).

Each delivery method has its own technical and pedagogical characteristics.

Delivery Methods (Cambridge Syllabus)

1. Computer‑Based Training (CBT)

Definition: Self‑contained software modules that run on a learner’s device without needing an internet connection.
Typical features: Interactive simulations, drag‑and‑drop activities, built‑in assessments, progress tracking.
Key technical standards: Packaged as SCORM 1.2/2004 or xAPI (Tin Can) for LMS compatibility.

2. Online Tutorials

Definition: Short, self‑paced modules that focus on a single concept or skill.
Typical platforms: YouTube, Khan Academy, Coursera “guided projects”, Codecademy.
Key technical standards: Video streamed via HLS/DASH; interactive elements built with HTML5/JavaScript.

3. Networked Courses (LMS‑driven)

Definition: Multi‑user courses hosted on a Learning Management System (LMS) that manage enrolment, content delivery, communication and assessment.
Common LMSs: Moodle, Blackboard, Canvas, Google Classroom.
Key technical standards: Support for SCORM, xAPI and LTI (Learning Tools Interoperability).

4. Massive Open Online Courses (MOOCs)

Definition: Free or low‑cost courses delivered over the internet, designed for unlimited enrolment.
Key characteristics:
- Open access – anyone can enrol.
- Large scale – thousands to millions of learners.
- Structured curriculum: video lectures, readings, quizzes, peer‑reviewed assignments.
- Certificates or micro‑credentials (often fee‑based).
Key technical standards: Video streamed via HLS/DASH; platform APIs use REST/JSON; compliance with GDPR and WCAG 2.1.

5. Video‑Conferencing (Synchronous Virtual Classrooms)

Definition: Real‑time interaction between instructor and learners using audio, video and shared digital resources.
Common tools: Zoom, Microsoft Teams, Google Meet, Cisco Webex.
Key technical standards: WebRTC (peer‑to‑peer) or proprietary cloud servers; end‑to‑end encryption.

Pedagogical Impact on Learners

Research and the Cambridge syllabus identify three core impacts of TEL. The table gives a concrete classroom example for each impact.

Impact	Example in a TEL context
Motivation	Progress bars and digital badges in a CBT module encourage learners to complete each activity.
Achievement	Instant feedback from quizzes in an online tutorial enables learners to correct misconceptions immediately.
Autonomy	Self‑paced study in a MOOC allows learners to decide when, where and at what speed to engage with the material.

Advantages and Disadvantages of Each Delivery Method

Method	Advantages (syllabus wording)	Disadvantages (syllabus wording)
Computer‑Based Training (CBT)	Works offline – useful where internet is unreliable. Highly interactive with instant feedback. Content can be packaged and reused (SCORM/xAPI).	Limited opportunities for social interaction. Updates require redistribution of the software. Potential device compatibility issues.
Online Tutorials	Short, focused content – ideal for micro‑learning. Cost‑effective for learners (often free). Easy to embed in LMSs or websites.	Depth of coverage may be shallow. Assessment is usually low‑stakes. Quality varies between providers.
Networked Courses (LMS)	Supports whole‑course management (enrolment, grading, analytics). Facilitates collaboration via forums, wikis and blogs. Scalable to large cohorts.	Requires reliable internet and server infrastructure. Learning curve for teachers and learners. Risk of information overload.
Massive Open Online Courses (MOOCs)	Open to anyone – expands global access. Rich multimedia and peer‑reviewed assessment. Certificates can enhance a CV.	Low completion rates (often < 10 %). Success depends heavily on self‑regulation. Instructional quality can be variable.
Video‑Conferencing	Real‑time interaction mimics face‑to‑face teaching. Immediate clarification of doubts. Breakout rooms support collaborative tasks.	Requires a stable high‑bandwidth connection. Coordinating time zones can be difficult. “Zoom fatigue” may reduce engagement.

Technical Characteristics Summary (exam‑relevant)

Standards & Protocols: SCORM / xAPI (content packaging), HLS / DASH (video streaming), WebRTC (live conferencing), LTI (tool integration).
Typical Minimum Bandwidth:
- CBT – offline (no bandwidth required).
- Online tutorials – ≥ 1 Mbps downstream.
- Networked courses – 2–3 Mbps upstream / downstream.
- MOOCs – ≥ 1.5 Mbps downstream (adaptive streaming).
- Video‑conferencing – ≥ 2 Mbps upstream / downstream for HD video.
Security & Data Protection: Encrypted connections (HTTPS/WSS), role‑based access control in LMSs, compliance with GDPR and accessibility standards (WCAG 2.1).

Application / Practice Opportunities (AO2)

Each task is linked to a delivery method and labelled with the assessment objective it targets.

CBT – AO2: Design a simple CBT module using an authoring tool and export it as a SCORM package.
Online Tutorial – AO2: Create a 5‑minute tutorial on a maths concept, embed an interactive quiz using H5P or Google Forms.
Networked Course – AO2: Set up a mock course in Moodle: add resources, configure a gradebook and create discussion forums.
MOOC – AO2: Outline a MOOC syllabus (weekly topics, learning outcomes, assessment types) and map it to the technical requirements of a streaming platform.
Video‑Conferencing – AO2: Run a 30‑minute live lesson, record it, and analyse bandwidth usage with a network‑monitoring tool.

Enrichment – Emerging Trends (optional)

Artificial intelligence for real‑time feedback, adaptive learning pathways and automated grading.
Virtual and augmented reality for immersive laboratory or field‑work simulations.
Micro‑learning delivered via push notifications on mobile apps.
Blockchain for tamper‑proof credentialing and transcript sharing.
Learning analytics powered by big data to predict at‑risk learners and trigger early interventions.

Summary

Technology‑enhanced learning comprises five delivery methods – CBT, online tutorials, networked courses, MOOCs and video‑conferencing – each with distinct technical specifications, pedagogical benefits and challenges. When designed well, TEL can increase learner motivation, achievement and autonomy. However, issues such as low completion rates, dependence on reliable internet and quality assurance must be managed. A clear understanding of both opportunities and limitations enables educators, learners and policymakers to make informed decisions about integrating TEL into education.
