Introduction to Educational Technology
Key concepts, historical milestones, and practical implications for teaching and learning
1. What Is Educational Technology?
| Term |
Definition |
| Educational Technology (EdTech) |
The systematic use of tools, resources, and processes—often digital—to support, enhance, and transform teaching and learning. |
| Learning Management System (LMS) |
Software platform that organizes content, tracks progress, and facilitates communication (e.g., Canvas, Moodle, Google Classroom). |
| Instructional Design (ID) |
The practice of creating learning experiences that are effective, efficient, and engaging, often following models such as ADDIE or SAM. |
| Digital Pedagogy |
Teaching approaches that intentionally integrate digital tools to achieve specific learning outcomes. |
2. Historical Overview
| Era |
Milestones |
Impact on Education |
| Pre‑computer (1900‑1960) |
Radio, film strips, overhead projectors |
Expanded reach of instructional media; introduced visual/audio learning. |
| Mainframe & Early Computer Age (1960‑1980) |
PLATO, Logo, first computer‑based instruction |
Pioneered interactive learning, simulation, and programming as a learning tool. |
| Personal Computer Boom (1980‑1995) |
Apple Macintosh, Windows, CD‑ROMs, HyperCard |
Shifted focus to individual learners; multimedia authoring tools emerged. |
| Internet & Web 1.0 (1995‑2005) |
Email, discussion boards, early LMS, OpenCourseWare |
Enabled remote access to resources; introduced asynchronous learning. |
| Web 2.0 & Mobile (2005‑2015) |
Blogs, wikis, MOOCs, smartphones, BYOD |
Emphasized collaboration, user‑generated content, and anytime/anywhere learning. |
| AI & Immersive Tech (2015‑present) |
Adaptive learning platforms, AR/VR, chatbots, learning analytics |
Personalizes pathways, creates immersive simulations, and provides data‑driven insights. |
3. Core Theoretical Foundations
| Theory |
Core Idea |
EdTech Application |
| Behaviorism |
Learning = observable change; reinforcement drives behavior. |
Drill‑and‑practice software, gamified quizzes, badge systems. |
| Cognitivism |
Knowledge is mentally constructed; focus on information processing. |
Concept maps, interactive simulations, spaced‑repetition apps. |
| Constructivism |
Learners actively build meaning through experience. |
Project‑based learning platforms, collaborative wikis, VR environments. |
| Social Learning (Bandura) |
Learning occurs through observation and modeling. |
Video tutorials, peer‑review tools, community forums. |
| Connectivism |
Knowledge resides in networks; learning is about making connections. |
Social media integration, learning analytics dashboards, open‑educational resources (OER). |
